Sentry Issue Notifications via Mattermost Webhooks
Unfortunately, the only third party plugin I could find was a few years out of date and didn’t seem like it was compatible with newer versions of Sentry.
After a bit of playing around, I figured the easiest way was to just write an intermediary API to accept webhooks from Sentry, format a message, and pass it onto Mattermost. This is now working nicely in our environment.
The code for my middleman can be found: sentry_mattermost_webhook.php
Setting this up is fairly easy:
- Place the script on a web server, edit it to replace the placeholder variables I’ve left in.
- In Sentry, go to Settings > Developer Settings > New Internal Integration. Give it a name, and set the ‘Webhook URL’ to the location of the above script. Grant the ‘Read’ permission for ‘Issue & Event’ and enable the ‘issue’ webhook trigger.
- In Mattermost, create a new ‘Incoming Webhook‘ and add its URL to the script on line 39.
And you’re away! While it’d have been nice for us to have a native solution within Sentry, I didn’t want to spend the time writing my own Sentry plugins. This way seemed more flexible.
