About PSP Client API

• The Transaction Report Service consumes the PSP client API and delivers transaction reports.
• Following authorization to the PSP API, an access token is generated and remains valid for 10 minutes. -The Transaction Report Service caches this token for 9 minutes and 45 seconds (with a 15-second buffer to avoid using a stale token) and automatically adds it as an authorization header to each request for the PSP API through an interceptor.

Run/Testing the Application

• You can try out the API live using Swagger. Live URL : https://transaction-report-service.onrender.com/swagger-ui/index.html
• No manual login/authentication is required. In the absence of a token, interceptors will automatically set it during the call.
• The token will be cached for a duration of 9 minutes and 45 seconds. Upon expiration, it will be evicted, and a new token will be provided.
• Local test: Access Swagger UI to test the API after running the project at http://localhost:8080/swagger-ui/index.html
• Please find api-contract.yml here
