Hi @Soumith

 

If you are using DPS Card and Account Services API, this product uses Mutual (Two-Way) SSL Authentication and Channel Encryption (CE), not X-Pay Token. For more information on this, please visit this page: 

 

DPS Card and Account Services Authentication Method (visa.com)

 

Please let me know if you have additional questions.

 

Thanks,
