Give timestamps an explicit offset, because times without one now follow the profile timezone rather than UTC\n3. Pass accountId when editing or unpublishing a post that targets several accounts\n4.

List workspaces first and send Publer-Workspace-Id on later calls, or expect a 403\n2. Poll /job_status/{job_id} after posts/schedule and read payload.failures, since status reads complete even when posts failed\n3. Use the Bearer-API scheme, not Bearer\n4.
