Apart from it, I am using PHP, to call the API using the CURL method, but when I am trying to call any of the VISA API, it's not working anymore. Can you please send me the PHP curl method format where can I change the credentials and can set the configuration to call any API? as I am trying multiple times but it's not working at my end.
I have also tried with the two-way-SSL method and its sample code to call another API but it's not working.
Kindly, assist me to fix this issue and guide me for the visa API configuration for direct visa payment. As the work is on priority and needs to configure it asap.
The ERROR 400 - 9124 Expected input credential was not present error usually occurs when the credentials used are invalid. I am sharing the below webinar on how to configure Two-way SSL with openSSL and Test on Postman.
