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 workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Merge Pull Request support batch operations?

Yes. Run Merge Pull Request inside a Loop node to process arrays. Tiny Command handles GitHub's rate limits automatically so you don't have to throttle manually.
