American Express (AMEX) Wallet Web Service

The project aimed to create a secure and reliable payment gateway for the AMEX wallet web service. Our team conducted a thorough analysis of the requirements and system architecture before developing a Restful (RESTEasy) web service with open APIs for payment solutions. We prioritized security by implementing JSON Web Encryption (JWE) for secure communication and digital signing with client certificates for authentication and authorization. The project was completed successfully within the timeline, delivering a robust payment gateway to enhance transaction safety for banks and merchants using the AMEX wallet web service.
