GitHub
We can do 2 types of integrations with GitHub:
- Receive alerts from GitHub (Incoming WebHook)
- Send commands to GitHub and optionally receive a response (Outgoing WebHook)
Receive alerts
- Create a new Incoming WebHook
- Select the channel where you will receive the alerts. You may wish to create a dedicated channel for your notifications.
- Select an account from which the alerts will be posted. You may wish to create a dedicated account just for notifications.
- Set the “Enable Scripts” option to
True. - Copy-paste one of the example scripts below.
- Save the integration. This will generate a webhook URL and secret for you.
- Go to your repository
Settings -> WebHooks & services -> Add WebHook - Paste your WebHook URL from pimentaCHAT into Payload URL
- Keep Content type as
application/json - Leave Secret empty and save
Example script 1:
This script will generate notifications for the following repository events:
- Issue events (create, edit, close, reopen, assign, label, etc)
- Issue comment events
- Push events (singular and multiple commits)

Customizing your integration scripts
The purpose of the integration script is to transform data in one format (the format provided by your incoming service, such as GitHub) into another format (the format expected by pimentaCHAT). Therefore, should you wish to customize either of the scripts presented above, you will need two resources:
Note that data comes into your script from GitHub as the request.content object.
The Handlebars template used by pimentaCHAT to render messages from a JSON object may also be useful, and can be found here.
Send commands to GitHub
This script only works for public repositories
- Create a new Outgoing WebHook
- Select the channel where you will use the commands and receive the responses
- Set URLs as
https://api.github.com/repos/User-Or-Org-Name/Repo-Namelikehttps://api.github.com/repos/pimentaCHAT - Enable Scripts
- Use this Script to listen for commands
pr ls,pr listandhelp
/* exported Script */
/* globals Store */
