Update an existing AI Task Builder Collection. This is a full replacement — all fields must be provided.

To preserve existing entities (collection items, page items) when updating, include their id fields in the request. Entities without IDs will be created as new, and existing entities not included in the request will be deleted.

Authentication

Authorizationstring

The Prolific API uses API token to authenticate requests. You can create an API token directly from your settings.

Your API token does not have an expiry date and carries full permission, so be sure to keep them secure.

If your token is leaked, delete it and create a new one directly in the app.

In your requests add Authorization header with the value Token <your token>.
