What Publishly actually supports for Xtoday — authentication, posting, analytics & how a failed post is reported. Nothing below is a roadmap item presented as shipped.
Platform facts last verified: 2026-08-10
Publishly connects to X using Official OAuth, can post to it today, and reports analytics back through Publishly. Any failed X post carries one of 20 documented failure codes, shared across every connected network.
| Capability | X |
|---|---|
| Authentication | Official OAuth |
| Posting via Publishly | Supported by Publishly |
| Analytics via Publishly | Supported by Publishly |
| Scheduling | Supported — schedule from the calendar or the public API, same as every other connected account. |
| Failure codes | Same shared catalog as every other network — the 20-code reference |
We don’t publish numbers we haven’t re-verified.
Media specs, character limits & rate limits vary by API version and change without much notice from the platform. Rather than print numbers here that go stale, Publishly points you at X’s own developer documentation — the detailed per-platform specs on this page are still being verified against the current API.
Every post to X authenticates using Official OAuth — Publishly never asks for your platform password to post on your behalf.

Ten networks, one API, one shared failure catalog.
