How do I publish a post to Threads?

Short answer: You can create post container in Threads by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Threads Create Post Container action to a workflow, map its 5 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 Create Post Container.

What does the Create Post Container action do in Threads?
Step 1 of Threads publishing: stages the post (text, media URL, alt text) and returns a creation_id. Pair with Publish Post to actually push it live.
What inputs does Create Post Container require?
Required: Media Type. 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 Threads returns an error?
The run history shows the failed step with its input and the error message Threads 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 Create Post Container support batch operations?
Run Create Post Container 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 Threads's rate limits.
