Post type: `now`, `schedule`, or `draft`

The top-level type field controls when (and whether) the post is published:

Value	Behaviour
`"now"`	Publish immediately. `date` is ignored.
`"schedule"`	Publish at the time given in `date` (ISO 8601).
`"draft"`	Save as a draft. The post is created and stored against the integration but not scheduled or published. You can promote it to a real post later from the Postiz UI.

Drafts are how you stage content via the API without committing to a publish time, useful for content review workflows or pre-filling a calendar from an external CMS.

Duplicating a post

There is no dedicated duplicate / clone endpoint. To copy an existing post, fetch it with GET /posts and submit the content as a new POST /posts request. Before re-submitting, strip the server-managed fields from the fetched object, re-sending them either causes validation errors or, worse, accidentally updates the original. At minimum drop:

id and any nested post IDs
createdAt, updatedAt, and any other timestamps
state / status / releaseId (these are assigned by the scheduler)
Anything else the API didn’t ask you to provide when you originally created the post

Then set a fresh type (now, schedule, or draft) and date, and POST the cleaned object.

Video cover frame (`thumbnailTimestamp`)

Each media object in a post’s image array accepts an optional thumbnailTimestamp field: the number of milliseconds into the video to use as the cover/thumbnail frame.

{
  "image": [{ "id": "vid-123", "path": "https://uploads.postiz.com/video.mp4", "thumbnailTimestamp": 3000 }]
}

Supported providers: Instagram, Instagram Standalone, TikTok Business, and TikTok (Direct Post only: the UPLOAD/inbox flow does not support cover selection). Other providers ignore the field. For TikTok, in our testing the cover was applied only to public posts (privacy_level: "PUBLIC_TO_EVERYONE"); posts published with a restricted privacy level kept the first frame as the cover.

Provider-Specific Settings

When creating posts, each social media platform requires different settings. The settings object must include a __type field that identifies the platform.

All 27 Supported Platforms

Platform	`__type`	Required Settings
X (Twitter)	`x`	`who_can_reply_post` (optional: `community`, `made_with_ai`, `paid_partnership`)

TikTok honors these settings only when content_posting_method is DIRECT_POST, with UPLOAD it keeps only the post content/title. duet, stitch, and video_made_with_ai apply to video posts only; autoAddMusic to photo posts only. See TikTok settings.
