How do I post a comment to a Twist thread?

Short answer: You can post comment in Twist by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Twist Post Comment action to a workflow, map its 2 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 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 run history shows the failed step with its input and the error message Twist 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 Post Comment support batch operations?

Run Post Comment 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 Twist's rate limits.
