Create and Update a Discourse Post

Create a Discourse topic, update its first post and read it back.

Setup

Connect a Discourse account allowed to create topics in the chosen category and edit its posts. The Open Flow connection requires a publicly reachable HTTPS forum; private network addresses are not supported. In Open Flow, select the account for Create the topic, Update the post and Read the post. Allow the create-topic Action for the first node and Provider API access for the two HTTP nodes. Run with the category ID, title, initial post and updated post. In n8n, connect the same Discourse credential to all three service nodes, set the forum URL in Set topic details to exactly match the credential’s forum URL, and enter the category ID, title and both bodies there.

Behavior

The workflow creates a topic, changes the first post and retrieves that same post. Both writes can notify forum members and trigger other integrations. An error stops later steps. There is no automatic retry or rollback; if a response is lost, inspect the forum before retrying to avoid duplicate topics or edits.

Changes to the source

Replace the example category and text with inputs and verify post identity after updating.
Use the Discourse create-topic Action and Provider API in Open Flow. Both formats use the current nested post update payload; the source n8n node sends the text at the top level.
