Customer Login API

This endpoint allows customers to authenticate and obtain access tokens for the FinHub platform.

​
Authentication Flow

The login process follows these steps:

  1. Client submits credentials (username/email and password)
  2. Server validates credentials
  3. If valid, server returns access and refresh tokens
  4. Client stores tokens for subsequent API calls
