Services
API Integration
A connected API is only part of a working integration.

API Integration
Follow the handoff between systems
We review authentication, field mappings, limits and the way errors are handled, then test exchanges with realistic records. The team needs to see both the successful transaction and what happens when the other service slows down or rejects it.
Connections to review
- REST & GraphQL API integration
- Authentication & security implementation
- Error handling & retry mechanisms
- API version change monitoring
- Integration testing & documentation
In practice
API Integration: a practical example
Follow an update from the source application into the receiving system. Then try a rejected request and an interrupted connection. Agree how duplicates, retries and corrected information are handled, and identify which team receives the evidence when the two systems disagree.
An illustrative scenario to discuss when planning your project.
