Webhooks allow you to receive information about the key events that happen in your Crowdin project, like completed translations or proofreading. After you configure a webhook for the project, Crowdin will start sending POST or GET requests with data to the webhook URL via HTTP.

Only owners and project managers can register a webhook.

Use Cases

You can add webhooks to build integrations with the services or with your backend. For example:

  • Set up a webhook to send notifications to the system you use.
  • Pass information to the third-party services with the specific request requirements (for example, HTTP method, сontent type).
  • Create custom integrations with Crowdin.


You can configure webhooks for the following types of events:

Adding Webhooks

To configure webhooks in Crowdin, open your project and go to Tools > Webhooks. Click Add Webhook to start configuring your new webhook.

You will need to provide the following information to register a webhook:

  • The webhook name (for example, “App Project Translated”).
  • The events to post to the URL. You can select either one event or a specific set of events.
  • The URL where the callback should be sent.
  • The request method that indicates the desired action to be performed for a given resource (use either GET or POST).
  • The content type for the POST request method (multipart/form-data, application/json, or application/x-www-form-urlencoded).
  • For the application/json content type, you can select Batch webhooks to merge multiple events into a single request.

Optionally, you can add special headers to your webhook. They can be used for additional security, as an authorization method, and more. For example, if you add headers, your webhook endpoint can check them to ensure that information is coming from Crowdin.

When adding a webhook, click Test webhook to see how your application will react to that call.

Add Webhook

Depending on your approach to webhook management, you might need to add dedicated Crowdin IP addresses to your firewall to allow Crowdin to open the pre-configured webhook URLs.

Edit or Delete Webhooks

Within a specific project, you can access and manage configured webhooks by editing or deleting them directly from the displayed list.
