Postiz talks to each platform through that platform’s own API, which usually means you have to register a developer app with them and give Postiz the resulting keys. This section covers that registration, one page per platform.
Looking for what a platform can actually carry, character limits, media rules and per-post settings? That is Posting rules by platform.

​
Ten platforms need no configuration at all

These providers take credentials that each user supplies in the Postiz dialog when they connect a channel. There is nothing for you to register and no environment variable to set. They are the quickest way to confirm a fresh install works.

​
Everything else needs a developer app

For the remaining platforms you register an app on the platform’s developer portal, then set the keys as environment variables on your instance. Each page in this section walks through one platform.

​
Redirect URIs

Every OAuth provider asks for a redirect URI. Postiz always uses the same shape:
So an instance at https://social.example.com connecting X uses https://social.example.com/integrations/social/x. The provider identifier is the one in the platform table, which is not always the name you expect: Farcaster is wrapcast, Google My Business is gmb.

​
Keys that are shared between platforms

Three pairs of platforms share credentials, which trips people up:
  • Instagram (Facebook Business) uses FACEBOOK_APP_ID and FACEBOOK_APP_SECRET, the same app as Facebook Page. Only Instagram Standalone uses INSTAGRAM_APP_ID and INSTAGRAM_APP_SECRET.
  • LinkedIn Page uses the same LINKEDIN_CLIENT_ID and LINKEDIN_CLIENT_SECRET as LinkedIn.
  • Google My Business falls back to the YouTube Google credentials if GOOGLE_GMB_CLIENT_ID and GOOGLE_GMB_CLIENT_SECRET are not set.

​
Unconfigured platforms still appear in the list

Postiz shows every platform in the Add Channel dialog whether or not its keys are set. Clicking one you have not configured produces a failed connect rather than a helpful message, so if a platform will not connect on a fresh install, check its keys first.
