Introduction to Workflow Webhooks
Shopify Flow is powerful, but it only reacts to events inside Shopify. Workflow Webhooks removes that limitation. It gives you a secure URL endpoint that external systems can POST to - and when they do, your Shopify Flow workflow fires instantly, with the payload data passed in as usable variables.
[!NOTE] This app was previously listed as Flow Webhooks. Same app, same install, new name.
How it works
- Your external tool sends an HTTP POST to your webhook URL with a JSON payload (e.g. name, email, question). Works with n8n, Make, Zapier, or any HTTP-capable tool.
- Workflow Webhooks receives it, authenticates the request, logs it with full headers and payload, then fires the linked Shopify Flow trigger.
- Shopify Flow runs your automation - tag a customer, send an email, update a
metafield - using the payload data as named variables (
{{fieldOne}},{{fieldTwo}},{{fieldThree}},{{fieldFour}}). You can also send additional data if you tick Security -> Allow Custom Request Body on the webhook. - One webhook endpoint can power any Flow automation.

| CORS support | Enable for browser-based or frontend integrations |
| Custom request body | Accept flexible payload structures from third-party platforms |
| Webhook dashboard | Manage, monitor, and test all endpoints in one place |
Authentication
| Method | How it works | Best for |
|---|---|---|
| None | No authentication | Testing only, not production |
| Static Token ✓ | Fixed token in the X-Api-Key header |
Most integrations (n8n, Make, Zapier) |
| HMAC SHA256 | Signature from payload + secret key | High-security or compliance |
[!TIP] The static-token header name is configurable per webhook in Advanced Settings, so you can match whatever header your sending system already uses. It defaults to
X-Api-Key.
Variable mapping
Workflow Webhooks lets you map fields in your incoming JSON payload to named variables that Shopify Flow can use. Define up to 4 field names in the Advanced Settings tab. You can also send additional data if you tick Security -> Allow Custom Request Body.
| Field in app | Your payload key | Reference in Flow |
|---|---|---|
| Field 1 | name |
{{fieldOne}} |
| Field 2 | email |
{{fieldTwo}} |
| Field 3 | question |
{{fieldThree}} |
| Field 4 | other |
{{fieldFour}} |
Common use cases
- Tag or update a Shopify customer when a form is submitted externally
- Trigger order or fulfillment actions from an n8n or Make workflow
- Sync contact data from a CRM or helpdesk into Shopify when a record changes
- Start a Shopify Flow when a Zapier automation completes
- Fire automations from a frontend form (with CORS enabled)
- Replace multiple single-purpose integrations with one unified webhook manager
