Shopify Flow: The Store Automations to Build First

Shopify Flow is the ecommerce automation app Shopify builds and gives away. Shopify’s help center (opens in new tab) lists it as a free app on the Basic, Grow, Advanced and Plus plans. In the Shopify stores we build and rebuild, it’s usually installed and barely used: a couple of templates someone switched on once, while staff still tag orders and check stock by hand. What follows is the set of automations we’d put in first, in order, along with the limit Shopify documents for each one.

The order is tagging, low-stock alerts, fraud holds, VIP routing and win-back. Tags come first because the other four workflows can branch on them. Low-stock alerts and fraud holds come next because each one catches a problem while there’s still time to act. VIP routing and win-back come last because they depend on the customer data the first three put in place.

Every platform fact below links to the Shopify, Klaviyo or App Store page it came from, all checked on September 10, 2026. Shopify ships Flow changes often, so read trigger names, limits and plan lines as a snapshot of that date. Where a vendor is describing its own product, the sentence says so, and we won’t repeat that caveat in every paragraph.

Is Shopify Flow only for Shopify Plus? No. Shopify’s Flow documentation (opens in new tab) says Shopify Flow is “a free app available on the Basic, Grow, Advanced, and Plus plans,” and adds that “Although most Shopify Flow features are available across all plans, there are some features that are accessible only to certain plans.” It then lists three gates: Grow, Advanced and Plus stores can use the Send HTTP Request action, Plus stores can use tasks created by custom partner apps, and each store gets Flow usage limits that follow the API limits of its plan.

Shopify’s API rate limits page (opens in new tab) puts numbers on that third gate: the GraphQL Admin API runs at 100 points per second at the standard limit, 200 on Advanced and 1,000 on Plus, so a Plus store’s API budget is ten times the standard one. Flow’s usage limits follow those plan limits, but Shopify doesn’t publish a Flow-specific run quota for any plan.

The current Run code (opens in new tab) and Send Admin API request (opens in new tab) pages list no plan requirement, which leaves two of Flow’s advanced actions outside the three gates as of September 10, 2026. For B2B, Shopify’s B2B plan features page (opens in new tab) marks Shopify Flow using B2B objects as available on all four plans, though Flow’s template examples page (opens in new tab) still carries a note limiting the B2B companies used in B2B workflows to Plus. Shopify’s Flow product page (opens in new tab) adds that “Flow is only available in English.”

Every workflow is built from three kinds of step. Shopify’s developer docs for Flow (opens in new tab) define a trigger as “An event that starts a workflow, and can be something that happens in a store or in an app,” a condition as “A rule that determines whether an action will be taken,” and an action as “A task that’s executed in a store or in an app when certain conditions are met.” Shopify’s workflow creation guide (opens in new tab) adds that “All workflows must start with a trigger from Shopify Flow or from an app.”

In a low-stock alert, the trigger is a variant’s inventory quantity changing, the condition checks whether stock just crossed your threshold, and the action messages whoever reorders. Apps can’t extend the middle step: the same developer page says “As a developer you cannot create a condition task,” so third-party apps plug in as triggers and actions while the branching logic stays inside Shopify Flow.

Flow runs workflows as soon as possible but doesn’t promise how fast. The workflow creation guide says “There is no defined length of time that it takes a workflow to complete.” It also warns that “Some fields in the GraphQL Admin API are populated asynchronously, particularly on orders,” and names fulfillments, UTM parameters and risk levels as data that might not exist yet when a workflow reads the order.

The same guide says “Orders and draft orders are treated separately by Flow,” so a workflow built on order triggers doesn’t act on draft orders. Conditions on tags have a ceiling: “Workflows that contain conditions that involve tags might not work if there are more than 250 tags associated with the order, product, or customer.”

Flow is a client of Shopify’s Admin API. Shopify’s Admin API concepts page for Flow (opens in new tab) says Flow evaluates conditions and takes actions on API version 2026-01, and that “Because Shopify releases new API versions every 3 months, some workflows might need to be updated when fields are changed or deprecated.” Shopify’s March 24, 2026 changelog (opens in new tab) says nearly all Admin API fields are now available natively in Flow, including fields that take arguments.

Beyond the three core step types, Flow has utility steps. Scheduled workflows run on a timer instead of waiting for a store event. Get data pulls lists of records into a workflow, For each loops over a list, and Count and Sum aggregate one, according to Shopify’s advanced workflows page (opens in new tab). The 40-wait-step cap in the table below comes from Shopify’s Flow troubleshooting page (opens in new tab).

When a wait ends, Flow re-reads store data instead of acting on what it saw at the trigger. The Wait reference (opens in new tab) gives the example of a customer whose refund during the wait flips the result of a spend-tier condition. Editing an active workflow changes what its waiting runs do, and deactivating or deleting it cancels them. For anything longer than 90 days, the page recommends a scheduled workflow with a Get data action.

Shopify keeps adding to what Get data can reach. The March 19, 2026 update (opens in new tab) added markets and articles, and the March 24, 2026 update (opens in new tab) added workflow runs, abandoned checkouts, inventory items, catalogs and pages, each returning up to 100 resources. A May 9, 2026 changelog (opens in new tab) added a Get analytics data action that runs ShopifyQL inside a workflow and returns the results as variables.

Flow’s text fields accept Liquid, the template language Shopify themes use, but in a different dialect. Shopify’s Flow variables reference (opens in new tab) says “Flow uses a variant of Liquid that most closely follows the open source library,” while theme Liquid “uses a different syntax for variables, and includes many more filters and tags than Flow supports.” A snippet copied from a theme file won’t necessarily run in a workflow.

Flow supports the conditional tags if, unless, elsif/else, case/when and and/or, the iteration tags for, cycle and tablerow, and, per the same page, “all of the open source Liquid filters.” It adds its own filters: date_minus and date_plus for date math, blake3, sha256, sha1 and md5 for hashing, and hmac_sha256 and hmac_sha1 for signing. The page recommends blake3 for new work and keeps the other three hashes for compatibility with third-party systems. The SHA, MD5 and HMAC filters shipped on September 12, 2025 (opens in new tab).

The variables page lists what Flow’s Liquid leaves out: “Flow doesn’t support dot notation that is available for some filters,” “Flow doesn’t support dot notation for metafields,” and “Flow doesn’t support using indexes to access items in a list.” You also can’t print a list or object by calling it directly, so the workaround is a for loop that picks out the fields you need. For mutation input, the Send Admin API request page (opens in new tab) says Flow supports a json Liquid filter.

Secrets use Liquid too. The Send HTTP request page (opens in new tab) references credentials as {{secrets.handle}}, and “Secret values are never visible in the Flow interface and are redacted from the workflow run logs.” If variable paths slow your team down, the variables page notes “You can ask Sidekick to write the Liquid for a step instead of tracing the variable path yourself.”

Shopify’s template library (opens in new tab) “provides hundreds of examples that demonstrate how to use Flow,” and that page sorts a sample of them into 13 categories, from B2B and Customer through Risk and Connector apps. The search is semantic: “Describe what you want to automate and any relevant templates that match your description display as search results.”

Shopify’s workflow creation guide (opens in new tab) says templates ship with placeholder data, such as tags and email recipients, that you’ll need to edit before activating, and many need a connector app installed. Our rule is that a template stays inactive until someone has read every step and replaced every placeholder.

Returns have their own triggers, added in Shopify’s August 16, 2024 update (opens in new tab), and templates such as “Cancel inactive returns,” which appears on the Wait reference (opens in new tab). How those fit into a full returns process is covered in our guide to ecommerce returns management on Shopify.

Tags are the simplest automation in Flow, and the other four workflows here read them. Shopify’s actions reference (opens in new tab) lists add and remove tag actions for customers, orders, draft orders and products. The triggers reference (opens in new tab) includes Customer tags added and Customer tags removed, so a tag written by one workflow can start another.

For customers, we’d start from “Organize customers by lifetime spend tiers,” “Organize customers by order count tiers” and “Track and reward customers based on lifetime spend,” all listed on Shopify’s Add customer tags reference (opens in new tab). For orders, Shopify’s template examples (opens in new tab) and Run code reference (opens in new tab) include “Tag orders by their shipping method,” “Tag orders paid with gift card” and “Tag orders with associated UTM campaign.” Shopify lists UTM parameters among the fields that populate asynchronously, so test the UTM workflow against real orders before anyone builds a report on its tags.

A store that tags every campaign, channel and promotion can push a customer record past the 250-tag condition ceiling, and tag conditions on that record may then stop working.

Shopify sends merchants to Flow for low-stock alerts. Its inventory overview (opens in new tab) says “If you need to receive direct notifications of low stock levels, then install an inventory alert app from the Shopify App Store,” and also that “You can also use Shopify Flow to set up low stock notifications.” The Stocky transition page (opens in new tab) is more direct: “Set up automated low-stock alerts using Shopify Flow so you can react before items run out.”

The trigger is Product variant inventory quantity changed, which the trigger reference (opens in new tab) says fires even when inventory tracking is off. Shopify’s examples page (opens in new tab) gives the condition rule: “When you create this type of workflow, the condition needs to check both the amounts before and after the inventory changes.” If the condition checks only the current quantity, every sale below the threshold sends another alert, as Shopify’s T-shirt example shows.

For multi-location stores, per-location stock comes from productVariant / inventoryItem / inventoryLevels / available, so a condition can alert on the location that ships instead of the store total. Start from “Get notified when product inventory is low,” “Send weekly email summary with list of low stock variants” or “Merchandise low stock products and hide when out of stock.” Shopify added triggers for inventory transfers on April 30, 2026 (opens in new tab).

Setting thresholds per location is inventory work, and our Shopify inventory management guide covers that side. This trigger runs on every inventory change in the store and is the high-volume example in Shopify’s optimization guide.

Build fraud workflows on the Order risk analyzed trigger, not Order created. Shopify’s workflow creation guide (opens in new tab) recommends this because risk level populates asynchronously, so an Order created workflow can read the order before its risk result exists. The trigger reference (opens in new tab) confirms the timing: “Workflows that start with the Order risk analyzed do not run immediately after an order is created.”

Does Shopify Flow read third-party fraud scores? Not through this trigger. The same page says “This trigger is only invoked for Shopify risk assessments and not for third-party assessments,” and the Risk section of Shopify’s template examples (opens in new tab) says “Risk results from third-party apps aren’t used.” Build your Flow fraud logic on Shopify’s own assessment, and treat any third-party fraud app as a separate system.

Your payment capture setting decides what Flow can do with a risky order. According to Shopify’s template examples, a store on manual capture can have a workflow capture only low- and medium-risk orders. With automatic capture and manual fulfillment, a workflow can cancel a risky order, but “You can’t prevent the payment from being captured in this case.”

Hold fulfillment order (opens in new tab) places a hold on each fulfillment order, with a reason, notes and an optional merchant notification. Cancel order (opens in new tab) “cancels the order that triggers the workflow, and voids the authorization,” with options to refund, restock and notify. A deprecated version of that action doesn’t void the authorization, so check which version an older workflow uses.

Our default is hold and notify, not auto-cancel. A hold keeps a person in the decision, while a cancel acts on Shopify’s risk level alone. Shopify’s templates cover both approaches: “Get notified about high risk orders before capturing payment,” “Request or hold fulfillments based on selected criteria,” “Capture payment if order is not high fraud risk” and “Cancel high-risk orders.”

If you run your own fraud analysis, the Create order risk assessment (opens in new tab) action displays it on the order, and “When this action creates a risk assessment, it will not cause Flow’s Order risk analyzed trigger to run again.” If Flow captures your payments, the Capture payment reference (opens in new tab) warns that an Order created workflow might miss an authorization from an order edit or a post-purchase upsell, and points to Order transaction created instead. Shopify added a Dispute created trigger for Shopify Payments chargebacks and inquiries on October 2, 2025 (opens in new tab).

VIP routing starts with a customer segment you define in Shopify and the Customer joined segment trigger, which fires when a customer enters the segment you pick. Its reference page (opens in new tab) lists customer tag, metafield and note actions as follow-ups. Shopify describes its “Welcome VIP customers” template this way: “Send high value customers a marketing email once they join the VIP customers segment. This automation requires a VIP customers segment.”

The triggers reference doesn’t list a matching trigger for a customer leaving a segment. When a workflow needs to know whether someone is still in a segment, the Look up customer in segment (opens in new tab) action checks membership from inside a running workflow.

A VIP tag can also route work to people. Shopify’s connector list (opens in new tab) describes Gorgias’s Flow action, Create a ticket, as one that “Creates a ticket containing a single internal note in Gorgias,” so a workflow can put a VIP’s order in front of your support team. If routing is part of a larger question about support spend, our breakdown of reducing customer support costs with AI covers the helpdesk side.

Shopify’s “Win back customers” template gives a discount to customers who haven’t ordered in the last 60 days, and it needs a winback segment to exist first, per the Customer joined segment reference (opens in new tab). Can Shopify Flow send marketing emails? Yes. Shopify’s template examples (opens in new tab) say a number of workflows integrate with Shopify Messaging to send branded marketing emails, and note that “Shopify Messaging marketing automation emails count toward your 10,000 free emails per calendar month.”

Most of the Shopify stores we build send email through Klaviyo, which changes the split of work. Flow notices a Shopify-side change and hands it to Klaviyo, and Klaviyo handles the send.

The handoff is the Klaviyo connector’s Track an event action, which Shopify’s connector list (opens in new tab) describes as “Pushes an event to Klaviyo.” That list still shows a Create a Campaign action, but Klaviyo’s own help article (opens in new tab) says “The Create a campaign action has been retired as of October 16th, 2025.” Klaviyo recommends Track an event in its place, with the event triggering a Klaviyo flow or defining a segment. Klaviyo owns the action, so we build to Klaviyo’s version.

In practice the win-back has two halves. On the Shopify side, you build a winback segment and a Flow workflow on Customer joined segment that tags the customer or tracks an event in Klaviyo. On the Klaviyo side, a flow triggered by that event decides what to send, when, and whether a discount goes in. Klaviyo’s troubleshooting notes say the connector’s Customer Properties and Event Properties boxes must hold valid JSON, so check those first when events don’t arrive.

Connectors are how the rest of your stack plugs into Flow. Shopify’s connectors reference (opens in new tab) says they “let you use specific apps to create triggers based on information from the app, or to create an action that uses an app.” Shopify’s page of apps that work with Shopify Flow (opens in new tab) listed 91 apps as of September 10, 2026, which counts that page, not every app that works with Flow.

For a DTC stack, the review, loyalty and messaging connectors are where most of the value sits. Okendo has an Okendo Review Created trigger, Yotpo Product Reviews & Photos has New Yotpo review and Yotpo review updated, Loox has New review, and Stamped Product Reviews & UGC has triggers for new reviews, NPS and questions. On the action side, Yotpo Loyalty & Rewards has Reward Points, Smile has Send Smile activity, SMSBump by Yotpo has Send SMS via SMSBump, and Omnisend has Track an event and Create or update the customer. Combined with the Gorgias action above, a review trigger can put new reviews in front of your support team as internal-note tickets.

Partner templates show up whether or not you’ve installed the app: shopify.dev (opens in new tab) tells developers that merchants “can discover your templates or tasks in Flow, even if they don’t have your app installed.” The App Store listings for Klaviyo (opens in new tab) and Gorgias (opens in new tab) both name Shopify Flow among the apps they work with.

Automation apps appear on the same connector page, including Mechanic, MESA and Arigato Automation. Mechanic’s connector, for example, adds four triggers for data Mechanic sends (customer, general, order and product) and a Send event to Mechanic action. What those apps do beyond their connectors is for their vendors to state, and we’d evaluate any of them against its own documentation.

The Generate text connector runs on an older OpenAI interface. Shopify’s Generate text reference (opens in new tab) says “Shopify Flow calls the legacy OpenAI completions API to generate text.”

Sidekick, the AI assistant in the Shopify admin, can draft a Flow workflow from a description. Shopify’s workflow creation guide (opens in new tab) says “You can use Sidekick to create a workflow in Shopify Flow based on a description of the workflow that you want.” The December 11, 2025 changelog (opens in new tab) says it “Works well for: customer and order tagging, email and Slack notifications, inventory alerts, scheduled automations.”

That list covers tagging and low-stock alerts, the first two automations in this post. The same changelog also states where Sidekick falls short: “Workflows with advanced Liquid or custom code may require manual editing.” Shopify’s changelog lists Sidekick workflow generation on Basic through Plus, and the help page lists no plan requirement.

Shopify’s help center lists four considerations for Sidekick-built workflows. The first two:

The third is that “Workflows generated by Sidekick are automatically tagged with sidekick.” The fourth says “You should thoroughly review and test the generated workflow to ensure that it’s functional and complete,” and warns that “Sidekick might omit business-specific logic in complex workflows that you need to refine before using the workflow.”

Inactive by default is the design we’d build a review process around anyway. The sidekick tag makes those workflows easy to filter for review, and changes Sidekick proposes to an existing workflow wait until you choose Apply changes or Discard changes.

Test the draft before activating it. Shopify added test runs (opens in new tab) on December 11, 2025 and describes them as “quick (about 10 seconds) and isolated from your live store.” Actions that change things outside the run, like tags and emails, don’t execute, while Run code, Count and Sum do. Since a May 14, 2026 update (opens in new tab), Sidekick can generate test events from real shop data, and Shopify’s testing page (opens in new tab) describes them as simulated events, for example one that passes the condition and one that fails.

After activation, audit it. Version history (opens in new tab), added May 5, 2026, logs edits, activations and deactivations with the staff member and timestamp, and the version history page (opens in new tab) marks changes made by Sidekick. Sidekick can also fix a workflow that won’t save and make optimization fixes such as adding query filters to Get data or inserting a Wait step, per Shopify’s troubleshooting (opens in new tab) and optimization (opens in new tab) pages.

Our sequence for any Sidekick-drafted workflow is to describe it, let Sidekick draft it inactive, have a person read every step and add the business logic Sidekick left out, run a passing and a failing test case, and then activate with an error alert in place. Sidekick drafting workflows is one narrow part of AI in Shopify operations. For the wider view, see our guide to agentic commerce on Shopify.

From this post’s publish date, September 15, 2026, Black Friday on November 27 is 73 days away. Shopify’s Flow product page (opens in new tab) says Flow “handles all the strains and pressures of huge sales like Black Friday Cyber Monday.” That’s Shopify marketing its own product. The figure Shopify sets beside it, “562M Workflows ran during Black Friday Cyber Monday,” gives no year and no per-store number, so plan around the documented limits instead.

The limits that apply at peak are these: no defined completion time for a run, order fields like risk and UTM data that populate asynchronously, usage limits tied to your plan’s API budget, and a warning on Shopify’s troubleshooting page (opens in new tab) when “your store has more than 10 active workflows using the same trigger.”

Shopify’s optimization page (opens in new tab) spells out the multiplier: “if a workflow fetches 100 products, and it runs 1000 times per minute, then it will be fetching 100,000 products per minute.” Its example of a high-volume trigger is Product variant inventory quantity changed, which “runs for every inventory change in a shop.” Every unit sold changes a variant’s inventory, so the low-stock workflow above runs most often when order volume is highest.

When workflows use too much, Flow throttles them. The troubleshooting page says Flow “will intentionally limit the execution of runs on your store, which might cause delays and timeout errors,” and that a GraphQL throttled error “can affect other workflows when they attempt to run.” A heavy inventory workflow can therefore delay the fraud hold that shares the store’s budget.

Of the fixes on the optimization page, we’d apply these four in September: combine workflows that share a trigger, put query filters on every Get data action, use metafield rather than metafields, and put a condition and a wait ahead of heavy data fetches so Flow only queries when the condition passes. Flow also fetches a field reused across steps one time, so consolidating workflows doesn’t mean fetching the same data twice.

Set up alerting before the traffic arrives. The Workflow error occurred (opens in new tab) trigger has Shopify templates for email, Slack and Shopify-alert notifications, and it runs only once per workflow version within 30 days, so a workflow that keeps failing sends one alert until it’s edited or 30 days pass. For a heartbeat, the Scheduled time reference (opens in new tab) lists “Send a notification when Order volume is less than 10 in last hour,” which Shopify describes as an order heartbeat notification, and a scheduled workflow can run as often as every 10 minutes.

Run search covers “the last 14 days of workflow runs,” according to Shopify’s monitoring page (opens in new tab), and manual runs (opens in new tab) cap at 50 orders, draft orders, customers or products. That makes backfilling a broken workflow’s missed orders a batch job. Since October 29, 2025 (opens in new tab), you can cancel in-progress runs, and runs retry automatically for up to 36 hours after a transient error.

Our Shopify Black Friday 2026 readiness checklist schedules automation wiring for the week beginning October 12, followed by a full rehearsal. Have your first Flow workflows built and tested before then, so October goes to consolidation and load rather than first drafts.

Can Shopify Flow call an external API? On Grow, Advanced and Plus, yes. The Send HTTP request page (opens in new tab) says “This action is only available to the Shopify Plus, Advanced, or Grow plans.” Where it’s available, it waits up to 30 seconds for a response and returns that response to the workflow, where Shopify suggests parsing it with Run code. A Basic store that needs an outside call has to go through a connector app or move to a higher plan.

Custom triggers and actions from your own app are the next boundary. Tasks from custom partner apps are Plus-only, and shopify.dev (opens in new tab) tells developers “your Flow app extensions are available only to a Shopify Plus store that has your app installed.” An Advanced store that wants a bespoke trigger from its own custom app runs into that gate. The gate is written for custom apps, and the public connectors listed earlier carry no plan line.

Code that needs the outside world is the third boundary. Run code is sandboxed: its reference page (opens in new tab) says it “supports ECMA2020 JavaScript. It doesn’t support the NodeJS or CommonJS APIs, or importing modules,” that “Your code can’t make HTTP calls (fetch),” and that “Random and clock-based functions can’t be used.” Execution is capped at 5 seconds and 10MB of memory, and the code’s input is a query over Flow’s own data, not the Admin API. Shopify keeps examples in a public code examples repository (opens in new tab).

Writing to the store past the built-in actions has limits too. Send Admin API request “can use most mutations in the GraphQL Admin API to make changes to your store, including mutations not yet available as actions in Flow,” but “The action doesn’t support GraphQL queries, only mutations.” Per the same page (opens in new tab), it doesn’t support asynchronous mutations, mutations that return a Job type, or some app-specific subscription, marketing activity and discount mutations. It can also fail after an API version change if a mutation or field it uses was changed or deprecated.

Bulk work hits volume ceilings. Get data stops at 100 items and For each at 1,000, a store can hold 1,000 workflows, and Shopify’s troubleshooting page (opens in new tab) says “Every workflow section has a combined upper execution limit of 36 hours.” A backfill across a large catalog or customer list becomes either a scheduled workflow that processes one batch per run, which is how Shopify’s own scheduled templates work, or an app.

The last boundary is sync between systems. Flow reacts to events in Shopify and in its connected apps, but we don’t use it as the sync layer between Shopify and an ERP, WMS or accounting system. Keeping two systems of record in agreement is integration work, and our Shopify ERP integration guide covers how those integrations get built.

Flow’s App Store listing (opens in new tab) shows a 4.7 rating from 13,829 reviews as of September 10, 2026. One reviewer on September 4, 2026 found it useful for small-scale tasks like updating metafields and tags, but wrote that “generally, Workflow is easily outclassed by just developing a custom app.” That’s one merchant’s view, and it lines up with the boundaries above rather than contradicting the rating.

Here’s our rule for where a job goes. If a Shopify event should change something in Shopify or in a connected app, and the job fits inside the limits above, it’s a Flow workflow. If a vendor already ships a connector or its own automation for the job, use that. If the job needs queries, writes and outside calls together, bulk volume, or a custom trigger on a plan below Plus, it’s an app or custom code.

If we were opening your store’s Flow editor on September 15, 2026, this is the order we’d build in, testing each workflow before the next goes live:

Then add error alerting and consolidate your triggers well before Black Friday on November 27. Shopify Flow costs nothing on your plan. The work is in the design, the testing, and knowing where Flow stops.

If you’d rather not work that out alone, start with our Shopify automation services. Send us your plan, your app stack, and where your team loses hours to manual work, and we’ll scope which Shopify Flow automations to build first, in what order, and which jobs belong in an app or custom code instead. Not a pitch deck. A build list your team can run.

The tool’s already on your plan. Put it to work.
