Facebook Reduce Data Error
This Facebook error usually points to a platform-side limitation or temporary instability rather than a unique Postly-specific content bug.
Please reduce the amount of data you're asking for, then retry your request
What it usually means
In practice, this error can appear when:
- Facebook is under temporary API strain
- large or media-heavy requests hit backend limits
- the same valid request succeeds later without changes
- Facebook returns a failure even though part of the request may still complete
What to do first
- Check whether the post actually published or partially published.
- Retry after a short interval instead of immediately rebuilding the content.
- Reduce unnecessary complexity if the payload is unusually heavy.
- Confirm the connected page is healthy and still authorized.
- Review Postly notifications and activity history for the final outcome.
What not to assume
Do not assume:
- the content is automatically invalid
- Postly changed the post payload in a destructive way
- every future Facebook post will fail the same way
This error has historically been intermittent.
If failures are clustered around very large media or unusually complex payloads, simplify one variable at a time. Change less, not more, so you can tell what actually mattered.
When to escalate
Escalate if:
- the same simplified post keeps failing repeatedly
- the account or page appears disconnected
- only one workspace or destination is affected
- publishing reports repeated failure over time instead of random recovery
