Getting started
- Introduction to Workflow WebhooksWorkflow Webhooks gives you secure HTTP endpoints that start Shopify Flow workflows, with payload data passed in as Flow variables.
- Create your first webhookStep-by-step: create a webhook endpoint, authenticate it, map your payload and connect it to a Shopify Flow workflow.
- AuthenticationSecure your webhook with a static token or HMAC SHA-256, including presets for Stripe, GitHub, Shopify, Slack, Typeform and Calendly.
- Payload mapping and Flow variablesMap up to four payload fields to Flow variables using dot paths, and forward the raw body, headers or query string when four is not enough.
- Plans and usageFree, Grow and Unlimited differ only in monthly invocation volume. What counts, what does not, and how to get alerted before you hit the cap.
Configuration
- Verifying signed webhooksWorkflow Webhooks checks a sender's HMAC signature before Shopify Flow runs: 22 built-in providers, plus a custom signature for any other service.
- Duplicate delivery protectionName the header carrying your sender's unique event id and repeat deliveries within 24 hours are accepted but not re-sent to Shopify Flow.
- Calling a webhook from FlowUse the Trigger Webhook action to call one of your webhooks as a step inside a Shopify Flow workflow.
- Synchronous responseHold the caller's request until your Shopify Flow workflow replies, using the Sync Webhook Trigger and the Return Webhook Response action.
- Scheduled URL pollingLet the app fetch a URL every 5 minutes to once a day and send the response into your webhook, so Flow runs on a timer instead of waiting for a caller.
- Body formats and splitting arraysWorkflow Webhooks parses JSON, form-encoded, multipart and XML bodies, and can fire one Shopify Flow run for every item in an array.
- Transform functionsRun your own function on every webhook request: reshape or enrich the payload, drop requests you do not need, or answer the caller directly.
- IP allowlistsLimit a Shopify Flow webhook to your sender's IP addresses or CIDR ranges, on top of its token or HMAC signature.
- CORS, the app proxy URL and browser callsEnable CORS, publish the webhook on the shop's own domain with the app proxy URL, and know what a browser-callable webhook exposes.
- Alerts and notification emailsGet an email before you run out of plan quota, or when an unusual share of your webhook invocations starts failing.
