The Transaction endpoints are essential for handling payment transactions and communicating with payment processors such as TSYS, Fiserv, Chase, and FIS within the payment processing system. They are designed to process various types of transactions, including authorization, capture, refund, and void.
These endpoints ensure the secure storage of transaction data, including transaction ID, client, user, amount, currency, status, and related metadata. They integrate with multiple payment processors using their respective APIs, and provide the status of a transaction (e.g., approved, declined, pending). The Transaction endpoints can retrieve transaction history for a client or user, with the ability to filter by date range, transaction type, and other relevant criteria. They also handle various error scenarios, such as invalid credentials or insufficient funds, and return appropriate error messages to the client. Additionally, these endpoints enforce transaction limits per client as configured within the system.
The design of Transactions endpoints emphasizes security, performance, scalability, reliability, and monitoring/logging. They ensure that sensitive data, such as card information, is securely transmitted, stored, and accessed. The endpoints are capable of handling a high volume of transactions and providing fast response times. They are designed to scale horizontally to accommodate growth in transaction volume and have mechanisms in place to handle failures, ensuring transaction data integrity. Finally, the endpoints include monitoring and logging capabilities to track performance, errors, and other relevant metrics.
The Transaction endpoints include the following APIs:
POST /transactions/authorization: Authorize a credit card
POST /transactions/capture: Capture an authorization
POST /transactions/sale: Process a sale transaction.
POST /transactions/refund: Refund a sale.
POST /transactions/void: Void a sale.
These endpoints offer robust capabilities for managing payment transactions and interacting with payment processors, providing a solid foundation for the payment processing system.
