Fern generates Webhook Reference documentation from an [OpenAPI specification](/learn/api-definitions/openapi/endpoints/webhooks). Fern supports webhooks through: * **OpenAPI 3.1+**: Use the native `webhooks` field with an `operationId` (recommended) * **OpenAPI 3.0**: Use the `x-fern-webhook: true` extension ## Configuration #### Set up your project structure Add your specification file to your `/fern` directory and create a `generators.yml` that references it: **`generators.yml`** ```yaml generators.yml api: path: openapi/openapi.yml ``` #### Add the Webhook Reference to your navigation Add `- api: Webhook Reference` to your navigation in `docs.yml`: **`docs.yml`** ```yml docs.yml navigation: - api: Webhook Reference api-name: webhooks-v1 ``` Use the `api-name` property to reference the folder containing your webhook definition. #### Customize the layout For a full list of configuration options and layout customizations, see [Customize API Reference layout](/learn/docs/api-references/customize-api-reference-layout). For a real-world example of webhook documentation generated from an API definition, check out [Webflow's webhooks](https://developers.webflow.com/data/reference/webhooks/events/form-submission). ### Include more than one Webhook Reference To include multiple webhook definitions in your documentation, use the `api-name` property. The `api-name` corresponds to the folder name containing your webhook definition. **`docs.yml`** ```yaml title="docs.yml" navigation: - api: Payment Webhooks api-name: payment-webhooks - api: Order Webhooks api-name: order-webhooks ``` ### Reference individual webhook events To display each webhook event as an individual page, reference it in the `layout` using the `subpackage_{tag}.{webhook-event-name}` format: **`docs.yml`** ```yaml title="docs.yml" navigation: - api: Webhook Reference api-name: webhooks-v1 layout: - subpackage_plants.newPlantWebhook ``` Where `{tag}` is the first tag (lowercase) and `{webhook-event-name}` is the `operationId` from your webhook definition. You must have the `tags` and `example` properties defined [in your webhook specification](/learn/api-definitions/openapi/endpoints/webhooks). > Use Fern Docs to generate your Webhook Reference documentation from an OpenAPI spec.
