Before you call either
Publer API + MCP
- List workspaces first and send Publer-Workspace-Id on later calls, or expect a 403
- Poll /job_status/{job_id} after posts/schedule and read payload.failures, since status reads complete even when posts failed
- Use the Bearer-API scheme, not Bearer
- Leave a one-minute gap between posts to the same account, or the job fails
- Read X-RateLimit-Reset after a 429 and wait until then, as there's no Retry-After
SocialCannon
- Use the sandbox before publishing to a real account.
- Check X quota separately from the general post allowance.
- Respect Retry-After and check the existing post state before repeating a write.
