Webhooks enable Help Scout to call a script on your server when one or more events have happened. Webhooks can be thought of as event listeners or push notifications.
Configuring webhooks can be done through the Help Scout user interface. Simply login, click on Apps in the top header bar, then select the Webhooks app.

Each webhook includes two headers:
- X-HelpScout-Event: Lists the event name for which this webhook event is being generated
- X-HelpScout-Signature: The computed signature generated by Help Scout. Used to know if the request is valid or not.
Webhooks can be verified as coming from Help Scout by calculating a digital signature. Each webhook request contains an X-HelpScout-Signature header, which is generated using the given secret key, along with the json encoded payload data sent in the request.
To verify if the request came from Help Scout, compute the HMAC hash and compare it to the header value sent in the request. If the computed signatures match, you can be sure the request was sent from Help Scout.
When using the Help Scout PHP library, this validation is automatically handled for you.

Thanks to one of our Help Scout customers for the following Node.js example.
Anything returned in the body of the response will be discarded. In order to know the webhook was successful, an HTTP status code of 200 must be returned.
Any status code other than 200 is a failure of some kind. A failed event is retried up to 10 times (with an increasing timeout period in between each retry). If the event fails all 10 retries, it is discarded.
Webhooks are automatically deactivated if three or more events get discarded.
The supported API clients have functionality included to facilitate working with webhooks.
