Webhooks

💬 Strapi team needs you to improve this documentation!

We are currently reworking the Backend Customization section of the Strapi documentation. If you would like to help, please feel free to fill in this form to share with us your opinions, needs and requests.

Webhook is a construct used by an application to notify other applications that an event occurred. More precisely, webhook is a user-defined HTTP callback. Using a webhook is a good way to tell third party providers to start some processing (CI, build, deployment ...).

The way a webhook works is by delivering information to a receiving application through HTTP requests (typically POST requests).

User content-type webhooks

To prevent from unintentionally sending any user's information to other applications, Webhooks will not work for the User content-type. If you need to notify other applications about changes in the Users collection, you can do so by creating Lifecycle hooks using the ./src/index.js example.

Available configurations

You can set webhook configurations inside the file ./config/server.

webhooks
- defaultHeaders: You can set default headers to use for your webhook requests. This option is overwritten by the headers set in the webhook itself.

Example configuration

JavaScript
TypeScript

./config/server.js
module.exports = {
  webhooks: {
    defaultHeaders: {
      "Custom-Header": "my-custom-header",
    },
  },
};

./config/server.ts
export default {
  webhooks: {
    defaultHeaders: {
      "Custom-Header": "my-custom-header",
    },
  },
};

Securing your webhooks

Most of the time, webhooks make requests to public URLs, therefore it is possible that someone may find that URL and send it wrong information.

To prevent this from happening you can send a header with an authentication token. Using the Admin panel you would have to do it for every webhook. Another way is to define defaultHeaders to add to every webhook requests.

You can configure these global headers by updating the file at ./config/server:

Simple token
Environment variable

JavaScript
TypeScript

./config/server.js
module.exports = {
  webhooks: {
    defaultHeaders: {
      Authorization: "Bearer my-very-secured-token",
    },
  },
};

./config.server.ts
export default {
  webhooks: {
    defaultHeaders: {
      Authorization: "Bearer my-very-secured-token",
    },
  },
};

JavaScript
TypeScript

./config/server.js
module.exports = {
  webhooks: {
    defaultHeaders: {
      Authorization: `Bearer ${process.env.WEBHOOK_TOKEN}`,
    },
  },
};

./config/server.ts
export default {
  webhooks: {
    defaultHeaders: {
      Authorization: `Bearer ${process.env.WEBHOOK_TOKEN}`,
    },
  },
};

If you are developing the webhook handler yourself you can now verify the token by reading the headers.

Available events

By default Strapi webhooks can be triggered by the following events:

Name	Description
`entry.create`	Triggered when a Content Type entry is created.
`entry.update`	Triggered when a Content Type entry is updated.
`entry.delete`	Triggered when a Content Type entry is deleted.
`entry.publish`	Triggered when a Content Type entry is published.*
`entry.unpublish`	Triggered when a Content Type entry is unpublished.*
`media.create`	Triggered when a media is created.
`media.update`	Triggered when a media is updated.
`media.delete`	Triggered when a media is deleted.
`review-workflows.updateEntryStage`	Triggered when content is moved between review stages (see review workflows). This event is only available with the Enterprise edition of Strapi.

*only when draftAndPublish is enabled on this Content Type.
