# Create a post group

`POST /v0/post-groups`

## Request

- Base URL: `https://api.schedulin.app`
- URL: `https://api.schedulin.app/v0/post-groups`
- Auth: one of:
  - API key in header `x-api-key`
  - OAuth 2 (authorization code, authorization URL `https://api.schedulin.app/oauth/authorize`, token URL `https://api.schedulin.app/oauth/token`, scopes: `posts:write`)

Create posts for several social accounts in one request — for example the same caption and image sent to Instagram, Threads and Facebook. Each post is validated exactly like `POST /v0/posts` (including per-platform rules), and media may reference stored library URLs or publicly reachable URLs; an external URL shared by several posts is imported once. The request is atomic: if any post is invalid, nothing is created. Posts with `action: "queue"` on the same account take consecutive queue slots. Up to 50 posts per request.

## Other responses

- `400`: Bad Request — the request isn't allowed in the resource's current state (e.g. editing a published post).
- `401`: Unauthorized — missing or invalid API key / access token.
- `403`: Forbidden — the credential lacks the required scope or access.
- `409`: Conflict
- `422`: Unprocessable request. Schema validation failures have `code: "INPUT_VALIDATION_FAILED"` and `data.fieldErrors` mapping each invalid field to its messages (nested issues name their full path, e.g. `media[0].url: ...`). Business-rule rejections (e.g. a `scheduledAt` in the past) have `code: "UNPROCESSABLE_CONTENT"` and carry the reason in `data.message` and `data.formErrors`.
- `429`: Rate limit exceeded. Wait `Retry-After` seconds before retrying.
- `500`: Internal Server Error
