Dashboard pages and API pages cover different jobs
Each platform has two entry points. The dashboard page describes what a team can schedule and publish through the bundle.social UI: post types, media, and per-platform options. The API page describes the same platform as an integration: which endpoint to call, which fields the platform requires, which scopes the connection needs, and what fails at publish time. If you are evaluating the product, start with the dashboard page. If you are integrating, start with the API page.
The platforms differ more than a unified API suggests
A single publish call hides real differences. Instagram requires a media container, a processing poll, and then a publish step. TikTok blocks certain privacy and spam-risk combinations and requires audit status before some flows. YouTube uses resumable uploads with a quota cost per video. Reddit rejects posts on community rules that no API can see in advance. Slack returns ok false inside a 200 response. The platform pages document those behaviors, because they determine what your integration must handle.
Character, media, and upload limits are per platform
Caption length, attachment counts, video duration, and comment length all vary by platform, and some vary by the user's own subscription. X allows 280 characters on free tiers and 25,000 on Premium. bundle.social validates against the current limit for the connected account instead of a lowest-common-denominator cap, so a post that a platform would reject fails validation before it reaches the platform.
Narrow surfaces get their own pages
Some platform capabilities are specific enough to document separately: TikTok's Content Posting API, YouTube resumable uploads, Snapchat Stories, LinkedIn company pages, comment reading and replies, music and commercial-audio rules, and audience demographics. Those pages sit under the same platform cluster and go deeper than the general platform page.
