Answer: Prepare one final video file, then fan out with platform-specific Postifys endpoints (or n8n nodes). Expect different account types, fields, and outcomes - especially TikTok inbox completion and no LinkedIn Company Pages.
Design rule
One media asset, six platform jobs - not one “magic” payload. Each network still needs the correct account type and fields.
| Platform | Account | Video path | Watch-out |
|---|---|---|---|
| Page | Feed / Reel fields | No personal profile wall | |
| Professional | type REEL | No personal accounts | |
| YouTube | Channel | Upload + title required | Provider processing after accept |
| Board | Image Pin today | Video Pin not claimed | |
| Member | Member video post | No Company Pages currently | |
| TikTok | Creator | Upload to inbox | Not Direct Post unless separately approved |
Recommended pipeline
- Encode once (MP4/H.264 when possible) and host a stable URL.
- Validate size against Postifys temporary-media limits.
- Create six platform jobs (API or n8n fan-out).
- Track each lane in Post History; retry only failures.
- For TikTok, complete publish in the creator app/inbox when required.
