Validating CAPTCHA challenge secret
From ePrize Developers Wiki
This is not a resource itself, but validation of a CAPTCHA challenge takes place as a side-effect of creating a profile if the API key is marked as requiring CAPTCHA validation. For these API keys, the client must send CAPTCHA challenge/response information in the request headers of the API call.
For full information please see create profile.
Headers
Both headers must be added to the create profile request for the challenge to be correctly validated.
Request header representation:
X-CAPTCHA-Challenge: /v1/{apikey}/captcha/{challenge-id} X-CAPTCHA-Response: {secret}
