Potential Micro-Services in a Payment Gateway

This post is particularly important for you if you want to:

• Do technology transformation to break a monolith payment solution to micoservices
• Want to cloud optimize your payment solution
• Want to develop payment solutions from scratch in a cloud native way
• Want to know potential microservices in a payment gateway
  

A payment gateway is a sophisticated system with many components and these components need to work in proper cohesion in order to deliver fast transactions with greatest possible transaction success rate. Following are potential micro-services to serve this purpose.

1. CRM Service: A service to facilitate dashboards, backend-operations to merchants, resellers & administrators. It is also used to enable, disable, configure pricing and other features of a merchant by admin.
   
   
2. Fraud prevention service: It can be a pre-auth or post-auth service running it’s business logic in parallel to other services.
   
   
3. Core Transaction Service: It can be a service to facilitate all transactions like authorization, sale, settle, refund etc. You can also do a logical separation of such micro-services instances on bases of transaction type or category of transaction like card-present and card-not-present.
   
   
4. SMS Service: It can be a service working in completely asynchronous ways to send SMS to customers
   
   
5. Email Service: It can be a service working in asynchronous ways to send Emails to customers
   
   
6. Transaction Batch Processing Service: It can be a service to process batches of transactions packed in files at scheduled times or on immediate bases. They can be required for processing refunds, settlements etc
   
   
7. Reporting Service: Merchants, resellers and acquirers need reports on daily bases and this micro-service can automate all such daily, weekly or monthly reports

 This list can grow as per the need and some other potential micro-services can also be like 3DS service, tokenization service, dynamic currency conversion service etc
