How do I merge a GitHub PR via API?

Short answer: You can merge pull request in GitHub by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the GitHub Merge Pull Request action to a workflow, map its 6 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Merge Pull Request.

What does the Merge Pull Request action do in GitHub?

Merges an open pull request with the chosen merge method (merge, squash, rebase). Required checks must pass first or you'll get a 405.

What inputs does Merge Pull Request require?

Required: Repository Owner, Repository Name, Pull Request Number. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if GitHub returns an error?

The run history shows the failed step with its input and the error message GitHub returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does Merge Pull Request support batch operations?

Run Merge Pull Request inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within GitHub's rate limits.
