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 log in, click on Manage > Apps in the top header bar, then select the Webhooks app.
Each request body uses the object format linked in the table below. All webhooks use the v1 payload unless otherwise specified in the webhook settings.
|Type||Event Name||Request Header||v1 Request Body||v2 Request Body|
|Conversation||Assigned||convo.assigned||v1 Conversation object||v2 Conversation object|
|Created||convo.created||v1 Conversation object||v2 Conversation object|
|Merged||convo.merged||v1 Conversation object||v2 Conversation object|
|Moved||convo.moved||v1 Conversation object||v2 Conversation object|
|Status Updated||convo.status||v1 Conversation object||v2 Conversation object|
|Tags Updated||convo.tags||v1 Conversation object||v2 Conversation object|
|Customer Reply||convo.customer.reply.created||v1 Conversation object||v2 Conversation object|
|Agent Reply||convo.agent.reply.created||v1 Conversation object||v2 Conversation object|
|Note Created||convo.note.created||v1 Conversation object||v2 Conversation object|
|Customer||Created||customer.created||v1 Customer object||v2 Customer object|
|Updated||customer.updated||v1 Customer object||v2 Customer object|
|Ratings||Rating Received||satisfaction.ratings||v1 Rating object||v2 Rating object|
Each webhook includes two Help Scout 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 our friends at Parse.com for the Ruby example below.
Thanks to Leo Arnold at Givve for sending us a nice Gist with a Ruby vulnerability fix.
And an updated ruby example using openssl (instead of hmac-sha1):
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 between
299 must be returned.
A status code of
410 will cause the webhook to get deactivated/deleted.
Any status code other than something between
410 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.
Note: The Agent Reply event will only return data for User-generated threads. Auto Reply messages are not included in this event.
