Mobile Payment Hybrid Capture API

The Hybrid Capture method performs authentication only in the checkout, while the capture is requested separately from the merchant server. Authentication and capture can be processed independently.

Important Notes

NOTE

Hybrid Capture Flow

1) Authentication request in the checkout (linkMethod='HBRD') → 2) Authentication success response (outStatCd='0061') → 3) Capture request using this API
  • Set the linkMethod parameter to HBRD when making the checkout request.
  • On authentication success, outStatCd returns 0061.
  • Use the trdNo returned upon authentication success as authTrdNo when requesting capture.
  • The merchant order number (mchtTrdNo) must be the same value used in the authentication request.
