For Slack, within a chat room open the cog ("Change settings") > "Add an app or integration". Search for "Semaphore", select a channel and you'll reach instructions and integration settings, as below.
Copy the webhook URL, save the integration and open return to Semaphore.
For Hipchat, see a separate guide for finding the right token.
Head over to your project settings, click on the Notifications tab, and choose your service. The screenshots feature Slack settings, but the build and deploy forms are identical across all services.
Note that notifications can only be set up and modified by users who have admin access to a project.
For both builds and deploys, Semaphore offers several filters to better control what information you're subscribed to:
Specifically for builds, you may choose to only receive notifications for a certain subset of branches. You can do this by selecting From whitelist in the Select branches dropdown box. A whitelist will appear, accepting Ruby regular expressions. Each line specifies a branch name pattern for which notifications will be sent.
If your project has deployment set up, a deploy section will appear in your chat notification settings, along with a checkbox list of configured servers. Untick any servers for which you do not wish to receive deploy notifications.
Save your settings, and you're done!
