How do I create a Discourse forum topic?
Short answer: You can create discourse topic in Discourse by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Discourse Create Discourse Topic action to a workflow, map its 3 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 Discourse Topic.
What does the Create Discourse Topic action do in Discourse?
Starts a new topic in a specified category with title, body (markdown), and optional tags. For "weekly release notes → auto-post to release-notes category" or "support request from external → create topic in Help category" workflows.
What inputs does Create Discourse Topic require?
Required: Title, Body (Markdown), Category ID. 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 Discourse returns an error?
The run history shows the failed step with its input and the error message Discourse 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 Discourse Topic support batch operations?
Run Create Discourse Topic 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 Discourse's rate limits.
