How to complete the challenge GET /challenger/guid (existing X-CHALLENGER)

By Alan Richardson · Published 2026-07-31

Use GET /challenger/{guid} to retrieve your current challenger progress as JSON.

The {guid} in the URL should match the active X-CHALLENGER value. The response body is the progress payload you can later send back to PUT /challenger/{guid}.

This is useful when you want to save your challenge progress outside the browser.
