Platform options

MADIAD Hub forwards any option a platform supports verbatim, so you are never limited to what is listed here. The fields below are the common and important ones. Prefix the field with the platform name where the option is platform-specific (<platform>_<field>). Array fields use the field[] convention — repeat the key once per value.

Every field on this page is optional unless explicitly marked required. Omitting a field uses the platform’s default.

TikTok

Field	Type	Effect
`privacy_level`	String	Who can see the post: `PUBLIC_TO_EVERYONE` (default), `MUTUAL_FOLLOW_FRIENDS`, `FOLLOWER_OF_CREATOR`, `SELF_ONLY`

brand_content_toggle and brand_organic_toggle can both be true at the same time — e.g. a creator promoting their own brand in a paid partnership.

Manual-credential channels

Eleven channels connect by pasting your own credential rather than by OAuth — see Channels for the field list and the connect endpoints. They accept only the shared caption / title: there are no additional creative options, and no analytics data is returned for any of them. Several of them also accept only one kind of post. Sending a channel a kind it does not take is refused locally with 400 invalid_request before anything is published — the matrix on Channels is the reference.

Chat channels

Text over the platform limit is truncated, not rejected, so keep captions within the limits shown in Character limits:

Telegram — 4,096 chars for text-only messages; 1,024 chars for media captions.
Discord — 2,000 chars.
Slack — text posts only.

Fediverse

Mastodon — text, photo and video. The per-post limit is set by the instance you connected (500 chars on most, but instances may raise it), so it is not pre-checked here.
Lemmy — text and photo. The shared caption becomes the post title; the target community is fixed at connect time.
Nostr — text only, relayed to the relays you supplied at connect time.

Publishing surfaces

WordPress — text, photo and video. The shared caption becomes the post title.
dev.to, Hashnode — text only; the shared caption becomes the article title.
Whop — text only, posted to the experience you supplied at connect time.
listmonk — text only, sent to the list you supplied at connect time. This one sends email to real recipients — test against a small list first.
