Why did I get API error code 10602?
This error occurs when an authorization has already been completed. The following API calls can produce this error:
- DoAuthorization.
- DoCapture.
- DoReauthorization.
- DoVoid.
Use the GetTransactionDetails API call to check the status of the authorization. If it’s pending, you can try to capture it.
