}Use this endpoint to programmatically create or update a preview deployment for a Git branch. If a preview already exists for the specified branch, the endpoint triggers a redeployment instead of creating a duplicate.
The response includes a

statusId that you can pass to Get deployment status to track the deployment progress.
Branch requirements
Thebranch must exist in the repository connected to your Mintlify project and you must have the Mintlify GitHub App installed. This endpoint does not support branches on forks. See Fork pull requests for how to preview changes from a fork.
Use cases
- CI/CD pipelines: Automatically create preview deployments when users open or update pull requests.
- Scheduled previews: Build previews from long-running feature branches on a schedule.
- Custom tooling: Integrate preview creation into internal workflows or Slack bots.
Access to previews
By default, previews created with this endpoint are publicly accessible unless you enable authentication for your previews. See Restrict access to preview deployments. To restrict access to a specific preview, pass anauth object in the request body. Mintlify applies the access setting to the preview before queuing the deployment. If you omit auth, the preview keeps its current access settings.
{ "type": "password", "password": "..." }: Anyone with the password can view the preview. Passwords must be at least 8 characters. Setting a password replaces any existing password on the preview.{ "type": "mintlify" }: Only members of your organization signed in to Mintlify can view the preview.
