<Update label="Apr 30, 2025">
  **Auto-invite, Completion URLs, audience size estimates, and enhanced participant profiles**

  * Added support for auto-invite when creating or editing projects so you can automatically invite participants to a project if they qualify after completing the screener. Only available when `targetResearchMethodology` is `unmoderatedStudy` or `survey`.
    ```json theme={null}
    automations: {
      autoinvite: true / false
    }
    ```
  * Added `completionUrl` to projects on creation, allowing participants to self-report task completion. Only available when `targetResearchMethodology` is `unmoderatedStudy` or `survey`.
  * Added an audience size estimate endpoint that provides an estimate of the audience that you can reach with your project.
  * Added topics and profile picture URLs to profile and screener response endpoints.
  * Added support to allow `targetMarketType` to be updated for draft projects via API.
  * Fixed a bug where NDAs could not be removed when updating a published project.
