Outgoing webhooks

This feature is supported on Sourcegraph versions 5.0 or more.

Outgoing webhooks can be configured on a Sourcegraph instance in order to send Sourcegraph events to external tools and services. This allows for deeper integrations between Sourcegraph and other applications.

Currently, webhooks are only implemented for events related to Batch Changes. They also cannot yet be scoped to specific entities, meaning that they will be triggered for all events of the specified type across Sourcegraph. Expanded support for more event types and scoped events is planned for the future. Please let us know what types of events you would like to see implemented next, or if you have any other feedback!

WARNING: Outgoing webhooks have the potential to send sensitive information about your repositories and code to other untrusted services. When configuring outgoing webhooks, be sure to only send events to trusted service URLs and to use the shared secret to verify any requests received.

Adding an outgoing webhook

Navigate to Site Admin > Configuration > Ougoing webhooks
Click + Create webhook
Fill out the form:
1. URL: URL endpoint of the external service that Sourcegraph should send webhook events to.
2. Secret: An arbitrary secret to share between Sourcegraph and the external service. A default value is provided, but you are free to change it.
3. Event types: The types of events that will trigger a webhook event. Currently, only events related to Batch Changes are supported.
Click Create

The outgoing webhook will now be created and active. To view or edit its details, or to see the log of event requests that have been sent for it, click the Edit button on the outgoing webhook's row. Created webhook
