Webhooks let you send real-time information from your application, database, or static site in Sevalla to another application whenever a specific event occurs. Unlike APIs, which require periodic requests to fetch data (also known as polling), webhooks automatically push data to the URL you specify. When you create a webhook in Sevalla, we send requests to the configured endpoint for the events you select. Each request includes an svl-signature header containing the webhook’s secret. Secrets can be rotated within the webhook, and you can keep the old secret active to ensure a smooth, zero-downtime key rotation. If a delivery fails, Sevalla automatically retries up to 12 times with progressively increasing intervals: 1 minute, 5 minutes, 10 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, 8 hours, 16 hours, 1 day, 2 days, and 3 days. For monitoring and debugging, you can view event delivery and response time charts for each webhook. Additionally, the Event Deliveries section allows you to inspect individual attempts, including full request and response details. ## Example application The [Sevalla Discord webhook example](https://github.com/sevalla-templates/webhook-discord-example) listens for events sent by Sevalla (such as `APP_DEPLOY` or `STATIC_SITE_UPDATE`) and forwards them as notifications to a Discord channel using your Discord Webhook URL. To use this example repository: 1. Fork the repository on GitHub. 2. [Add an application](https://docs.sevalla.com/applications/get-started/add-an-application) with the repository in Sevalla. 3. Create a [Discord webhook](https://support.discord.com/hc/en-us/articles/228383668-Intro-to-Webhooks). 4. Create a webhook in Sevalla for the `APP_DEPLOY` event, using a dummy webhook URL to obtain the webhook secret. 5. Add the following [environment variables](https://docs.sevalla.com/applications/environment-variables) ```text theme={null} SEVALLA_WEBHOOK_SECRET= DISCORD_WEBHOOK_URL= ``` 6. Deploy the application. Once deployed, click **View** and copy the URL. 7. Update the webhook endpoint with the URL from the deployed application in the format: `https://your-app.sevalla.app/webhook` The webhook will now send notifications to your Discord channel whenever an application is deployed within your Sevalla company. ## Create a webhook To create a webhook in Sevalla, go to **Integration** > **Webhooks** > **Create webhook**. Create a new webhook in Sevalla

Complete the details as follows: * **Endpoint:** Enter the URL you want to send the requests to. * **Description:** Add a description for the webhook. * **Allowed events:** You can select all events or choose the events you want to send requests for from the following: * `APP_CREATE` * `APP_UPDATE` * `APP_DELETE` * `APP_DEPLOY` * `DATABASE_CREATE` * `DATABASE_UPDATE` * `DATABASE_DELETE` * `STATIC_SITE_CREATE` * `STATIC_SITE_UPDATE` * `STATIC_SITE_DELETE` * `STATIC_SITE_DEPLOY` Click **Create webhook**. Add the webhook details

Once the webhook is set up, you can view and update its details, monitor event deliveries and response time charts, and inspect each delivery attempt under the Event Deliveries section, including full request and response details. View and update the webhook

## Roll the webhook secret To rotate your webhook secret, select the webhook and click **Roll secret**. Roll the secret for the webhook

Choose when you want the old secret to expire and click **Continue**. Select the expiration time for the old secret

## Update the webhook To change the endpoint, description, or allowed events for the webhook, click **Update**. Update the webhook details

Change the required information, and then click **Update webhook**. ## Event deliveries You can inspect each request attempt within **Event deliveries**. This shows you the individual attempt details, the request that was made, and the response details. Webhook event deliveries

## Disable a webhook To disable a webhook, within the webhook **Danger zone**, click **Disable webhook** and then click **Continue**. This stops the webhook from sending events to the endpoint. You can re-enable the webhook to start sending events again at any time. Disable the webhook

## Delete a webhook To delete a webhook, within the webhook **Danger zone**, click **Delete webhook** and then click **Continue**. This completely removes the webhook and its data. This action cannot be undone, and the data cannot be retrieved once it has been deleted. Delete the webhook
