CaptchaSolver

typedef · Source

Solves an hCaptcha challenge returned by Discord and returns a verified token.

When a request hits a captcha challenge, the REST handler calls this function with the challenge payload and the user agent that Discord observed, then replays the original request with the returned token as the X-Captcha-Key header (and Discord's captcha_rqtoken as X-Captcha-Rqtoken).

Common implementations delegate to a commercial solving service (for example CapSolver or 2captcha). The function must resolve to a non-empty string token; any other value rejects the request with CAPTCHA_SOLVER_INVALID_RESPONSE.

Solver failures propagate unchanged so callers can distinguish them from HTTP failures. Type: functionParameters
