# Introduction to Workflow Webhooks

Shopify Flow is powerful, but it only reacts to events inside Shopify. [**Workflow Webhooks**](https://apps.shopify.com/flow-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.

| Authentication | Static Token (simple) or HMAC SHA256 (tamper-proof) |
| Invocation history | Full log of every request - timestamp, payload, headers, and status |
| 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
