PII inquiry: submit the ID card as one PDF
Same PII inquiry as POST /api/FRAServices/PersonallyIdentifiableInformation, but the national ID is uploaded as one PDF file that contains both the front and the back, instead of two base64 images.
The request is multipart/form-data. The file must be a real PDF (not another file renamed to .pdf) and at most 5 MB. The front and back are read from the PDF and saved as the usual ID front and ID back steps, so the response has the same shape as the image variant.
OTP is optional: to prove phone-number ownership, call POST /api/FRAServices/RequestOtpForPii first and send otpRequestId and otpCode together. Send both or neither.
Authentication
End-user JWT from registration or login. Required for verification, signing, and user-scoped operations.
Request
Optional. The otpRequestId returned by POST /api/FRAServices/RequestOtpForPii. Send together with otpCode.
Optional. The OTP the user received. Send together with otpRequestId.
Optional. Defaults to false. Set it to true to skip the spoofing check on the ID pages read from the PDF, so a scanned or printed copy is not rejected as a forged document (5005). Every other document check still runs.
