Before you call either

Mixpost API + MCP

  1. Call list-workspaces first. Workspace endpoints sit under /api/{workspaceUuid}
  2. Check MIXPOST_CORE_PATH. It's empty by default from Pro v7 but defaults to mixpost in older versions and Lite
  3. Create the token as a Viewer-role user when the agent only needs to read
  4. Use unschedule-post rather than delete-post when a person wants a post pulled back to draft
  5. Expect HTTP 422 with an errors.limit entry when a Cloud plan limit is hit

SocialCannon

  1. Use the sandbox before publishing to a real account.
  2. Check X quota separately from the general post allowance.
  3. Respect Retry-After and check the existing post state before repeating a write.
