GitHub Pull Request Slack Notifier

Automatically notify your Slack channel when a specific developer opens a new GitHub pull request - no more missed PRs.

Stop manually checking GitHub for new pull requests from specific contributors. Use this AI agent template to automatically monitor GitHub for new pull requests from designated users and post an instant notification to your Slack channel when one is opened.

Whether you're a team lead staying on top of your team's code contributions, a DevOps engineer monitoring external contributors, or a project manager tracking development progress, this template keeps your team informed in Slack the moment new work is ready for review.

How this template works

This agent monitors GitHub for new pull requests and notifies Slack automatically. Here's how it works:

A new pull request is opened on GitHub in your specified repository.
The agent checks whether the PR was created by one of the users on your monitored list.
If the PR matches a monitored user, the agent composes a notification with the PR title, description, and a direct link.
The notification is posted to your designated Slack channel immediately.

Once your Zaps are published, the workflow runs automatically - no manual steps needed.

Frequently asked questions

Can I monitor multiple GitHub repositories?

The template monitors one repository by default. You can duplicate the agent for each additional repository or configure the trigger to watch a GitHub organization for PRs across all repos.

Can I track all pull requests instead of just specific users?

Yes. Remove the username filter to receive notifications for all new pull requests opened in the repository.

Can the notification include the PR description?

Yes. You can configure the Slack message to include the PR title, description, target branch, and a direct link to the PR on GitHub.

Can this work with GitLab or Bitbucket instead of GitHub?

The template is configured for GitHub. Zapier supports GitLab and Bitbucket as well, so you can adapt the trigger to work with either platform.
