About the project

A start-up in the US wanted to integrate multiple payment gateways on their online B2B SaaS portal to collect payments for their services from their customers through Credit cards & Debit cards. They wanted the system to utilize online payments, reconcile transactions and charge the customers using their authorization.

Problem

The new system should provide ways to accept cards on the existing web application, authorize, and charge while ensuring that the payments and the transactions are secure. The payment gateways to be supported had varied integrations, some providing purely backend authorizations where the cards’ authorizations had come through PoS terminals, while some other providing client-side widget based authorizations on the UI.

Solution

The existing B2B product was built on an AWS solution. C4Scale researched on problem scope, requirements and built an innovative generic solution to handle multiple payment gateways using a secure API layer on AWS. The architecture and the solution uses a mix of AWS Amplify, CodeCommit, CodeBuild, CodePipeline, React.js, Node.js Backend, API Gateways, JWT, RDS (PostgreSQL), DNS/Route53, AWS KMS, Cognito etc. The portal accepts the payments from multiple payment gateways such as Stripe, Tempus etc.
