I will fix or integrate a rest API in your java application
Rony Reyna
About this gig
Is your application failing to connect to another service? I can troubleshoot or implement a focused REST API integration in an existing Java or Spring Boot application. Basic provides an API review and a written plan. Standard covers one agreed endpoint or failing connection. Premium covers a small workflow using up to two endpoints from the same provider, with error handling and logging. Deliverables include source changes, example requests, tests and setup notes. Please share the provider documentation, expected data flow and test access before ordering. Provider fees, subscriptions, bulk migrations and additional systems are excluded. Written communication in Spanish or basic English.
