FAQ

Questions about Post Comment.

What does the Post Comment action do in Twist?

Posts a comment to an existing Twist thread, with Markdown support and optional attachments. Used for sending automated status updates into an ongoing discussion.

What inputs does Post Comment require?

Required: Thread ID, Content (Markdown). 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 Twist 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 Post Comment support batch operations?

Yes. Run Post Comment inside a Loop node to process arrays. Tiny Command handles Twist's rate limits automatically so you don't have to throttle manually.
