About API Development and Integration
API work begins with a contract for the data exchanged, authentication and expected failure behaviour. We implement validation, integration tests and documentation around the systems that need to communicate.
Why It Matters
Why API Development and Integration Matters for Your Business
A connection can fail silently when upstream data or interfaces change. Versioning, useful logs and ownership for operational alerts make the integration easier to support.
