How to read the matrix
Yes means that the product has an implementation for that action. It does not promise that an account is connected, a file meets every check, or a network will accept a post. No and not available mean that this route through PostEveryPlatform does not offer it. A media requirement applies even if the caption is empty.
Image counts are split by format. A PDF is a document, not an image. A video goes alone rather than alongside images. For a text-only destination, optional media means you can write without attaching a file. For a media destination, first choose the file and then check the format.
What the checks mean
- Text is counted as Unicode characters. An emoji sequence can contain several characters. X Premium uses the connected account's text limit when available, rather than the default in this table.
- First comments have both a partner ceiling and a storage cap. The product trims and truncates the top-level first_comment before saving. JavaScript string code units differ from Unicode characters when text contains emoji.
- Threads use the active provider's part limit. On reply-chain platforms, later parts cannot carry files when the provider's part-media count is zero. Destinations without thread support receive joined text.
- Title limits apply where the format uses a title. LinkedIn titles are for PDF documents; Google Business titles are for events and offers. Reddit requires a title and stores it with its own cap.
- Alt text is listed separately for images and video. A shared description is only sent to destinations where the provider supports that file kind. Missing support is shown explicitly.
- Inbox means importing comments on your posts and replying to them. Hide and like depend on the individual comment as well as the provider. It does not include direct messages or a general search of public conversations.
- Post analytics lists the fields the integration reads. It needs our posting partner's analytics access and a post reference; a field can be unavailable. These cells do not claim that every network returns every metric.
- Special options are the supported field names in NET_OPTS. Other settings, such as video privacy, still appear on the individual platform pages and in the account capabilities response.
Plan with an agent
An agent can read the connected account's capabilities before it writes. Those capabilities include the account's text limit, format rules and available choice lists. Account details can matter: an X Premium account can have a different text limit from the default shown here. Use the account response when checking a particular post.
The preview tools return problems and warnings without saving a post. Fix the problems, show the owner each destination's version, and save a draft or schedule only as requested. Agent posts wait for the owner's approval by default. A workspace with no plan or trial is read-only; writes answer plan_required. Choose an agent recipe or open the API reference.
