<Update label="Aug 11, 2025">
  **\[Action Required] Breaking changes to Respondent API — live Sept 15**

  We're rolling out several breaking changes to the API and want to ensure you're fully informed and prepared.

  ### What's changing?

  * The `publicDescription` field will be required to publish projects.
  * We're enabling webhook retries. A 2xx status code will be expected within 3 seconds; if not, we'll retry delivery up to 5 times at 10-minute intervals.
  * Screener questions will be limited to a maximum of 40 per project when adding single or multiple questions.

  ### Why are we changing?

  These updates are designed to:

  * Improve recruitment efficiency and the quality of participant experiences.
  * Ensure more reliable event delivery through webhook retries and reduce reliance on frequent polling or manual intervention.

  ### Key dates

  * **Aug 18, 2025** — these changes go live in our staging environment.
  * **Sept 15, 2025** — these changes go live in our production environment.

  ### Action required

  * Require your researchers to add a description to projects created on your platform prior to Sept 15, 2025.
  * If you have a webhook set up with us, ensure it responds with a 2xx response within 3 seconds prior to Sept 15, 2025.
  * Enforce a maximum screener question limit of 40 questions per project on your platform prior to Sept 15, 2025.
