Urgent Developer Needed for API Integration

We are looking for an experienced developer to complete a small but urgent integration task for our existing application. The project involves integrating a third-party API/service, ensuring proper data flow, handling authentication, validating responses, and resolving any integration-related issues. The ideal candidate should have experience with REST APIs, webhooks, JSON, authentication methods, and debugging integration problems. Strong knowledge of PHP, Laravel, Node.js, or similar backend technologies is a plus. The project budget is $25 (Fixed Price), and we need someone who can start immediately and deliver a reliable, well-tested solution within a short timeframe. Please include your relevant experience with API integrations, similar projects you have completed, and confirm your availability to start right away. Successful completion may lead to additional integration and backend development opportunities.
