Custom messages for Github Slack integration for issue tracking

Question

Is it possible to customize the messages that github will send to the slack webhook? I was able to set it up to where I get notifications whenever an issue is created/deleted/edited, however I would like to only get notifications for specific issues with a certain label and also be able to change the format of the notification.

With this level of customization, you will likely need to write a bit of custom code that:

1. Receives and authenticates the Github webhook. This means you need to host the code someplace as a web service, for example in Heroku.
2. Filters down to only the events that matter to you with the custom criteria you listed above.
3. Formats a custom Slack message in markdown based on the payload of the Github event.
4. Posts that message to Slack - probably the simplest solution is to use the Slack incoming webhooks.
