Connect your application to the services your business uses with a custom ASP NET Core API or integration.

The $350 package includes up to 3 REST API endpoints OR one simple third-party integration. Delivery takes 1 week and includes source code, setup notes and 2 revisions.

I develop backends with C# and ASP NET Core and can help with request validation, API responses, webhooks, existing API fixes and connecting an Angular frontend to an API.

Before starting, please provide your endpoint specification, third-party API documentation, sample inputs and expected outputs, plus relevant existing code. We will agree on the exact scope and acceptance criteria.

Database integration, authentication, deployment and larger workflows can be quoted separately. Hosting, paid service subscriptions and API usage fees are not included. Revisions cover the agreed scope; new endpoints and features need a separate quote.
