Answer: Prefer APIs that expose explicit platform endpoints, clear OAuth/account targeting, media proxy options, and status history. Postifys provides those for six networks with documented TikTok inbox and LinkedIn member limits.
Evaluation checklist
- Which account types are actually supported?
- Are Reels/video uploads documented separately from images?
- Can you retry and inspect failures?
- Is Direct Post claimed only when approved?
See Publishing API and Docs.
What this means in a real publishing workflow
A useful publishing API comparison starts with the workflow you must operate, not the length of a vendor feature list. Check account ownership, supported destination types, asynchronous processing, media transport, retry behavior, and whether OAuth tokens remain outside your automation tool.
Recommended implementation
- List every required destination: Facebook Page, Instagram professional account, YouTube channel, Pinterest board, LinkedIn member, or TikTok creator.
- Test one real image and one real video through the API before evaluating bulk automation.
- Record returned submission IDs and confirm that failures remain visible and safely retryable.
- Compare operational limits, approval requirements, pricing units, and support for your exact account types.
How to verify the fix
For Postifys, use the connection endpoints to populate destination selectors, submit through the platform-specific endpoint, and track the returned history ID. Do not assume one generic payload maps perfectly to every network.
Operational check: Test with one item, confirm the final destination and Postifys history state, and only then enable the recurring workflow. Keep the returned Postifys ID beside the source row so every result remains traceable.
