Get responses for a Task Builder Collection.

**Note:** This endpoint is coming soon and is not yet available.

Reference: https://docs.prolific.com/api-reference/task-builder/get-collection-responses

## Authentication

- `Authorization` header (required) (prefixed with ` Token  `) — 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>`.
