Not sure which Windows tab to use? The two aren’t interchangeable — pasting one into the wrong shell fails with a ... is not recognized error. Use CMD only in classic Command Prompt. Use PowerShell if your terminal is PowerShell, Windows Terminal, or VS Code’s integrated terminal — the default on most modern Windows setups. The PowerShell example uses Invoke-RestMethod rather than curl.exe to avoid PowerShell’s known issues passing complex quoted JSON to external executables.
Response (correct code)
{ "valid": true}
Response (wrong code)
{ "valid": false, "attempts_remaining": 3}
Each otp_id allows a limited number of incorrect attempts (default 5). Once exhausted, verification returns the otp_max_attempts error instead of valid: false — send a new code rather than retrying indefinitely. An expired code returns otp_expired. Both are structured errors, not valid: false — see Errors.
