# Introduction to Vyafac API

The **Vyafac API** is a **payment gateway** that provides programmatic access to transaction
processing functionality. This RESTful implementation exposes endpoints for payment operations,
refunds, and transaction monitoring.

## Technical Overview

This documentation serves as the reference specification for integrating with the Vyafac payment
infrastructure. It contains:

- **Authentication & Authorization**: Token-based access control mechanisms and scope limitations.
- **Endpoints & Methods**: HTTP verb specifications, request/response schemas, and resource paths.
- **Error Handling**: Error codes, exception handling patterns, and response structures.
- **Security Best Practices**: TLS requirements, token rotation protocols, and security headers.


## Implementation Notes

Developers implementing this API should be familiar with RESTful concepts, HTTP status codes,
and standard authentication flows. The API follows JSON formatting for all request and response
bodies.

API versioning is managed through URI path prefixing. Rate limiting is enforced and detailed
in the appropriate sections.

This documentation assumes familiarity with payment processing concepts.
