FAQ

Questions about Create or Update File.

What does the Create or Update File action do in GitHub?

Creates or updates a file in a GitHub repository in a single commit, with branch, commit message, and content. The SHA is auto-fetched on update; the standard tool for small file commits without a full git client.

What inputs does Create or Update File require?

Required: Owner, Repository, File Path, Commit Message, File Content (base64). 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 Create or Update File support batch operations?

Yes. Run Create or Update File inside a Loop node to process arrays. TinyCommand handles GitHub's rate limits automatically so you don't have to throttle manually.
