⌨️Request identity verification API

Sends OTP number via SMS confirming the user's identity based on the submitted personal information.

Sends OTP number confirming user's identity via SMS.

POST https://api.iamport.kr/certifications/otp/request

If the user's personal information is passed to the API and verified by the carrier, an OTP (6-digit verification number) is sent to the user via SMS. This is only supported by some merchants who have been pre-approved by the carrier, and is currently only being serviced through Danal.

You can call the API by directly entering the name, date of birth + 7th digit of social security number, mobile phone number, and carrier information from the merchant. If the transmitted personal information is correct, a verification code SMS is sent to the mobile phone.

When you receive an HTTP Status 200 response, it contains the verification ID (imp_uid) in the response body. To complete the verification process, call the /certifications/otp/confirm/{imp_uid} API with the OTP number.
