What this operation supports in Circle
Retrieves a single post's full details by its ID, including its content, author, and the Space it belongs to.
Implementation details
This returns the post itself -- its comments are fetched through a separate call rather than being embedded automatically in this response.
Operational considerations
Confirming a post still exists (hasn't been deleted) before taking further action on it avoids automations failing partway through a multi-step process.
Use cases
1) Mirror Circle posts to an external CMS; 2) Populate dashboards with post metrics; 3) Validate post content before automation steps; 4) Archive posts in external storage.
