Rivac LabsAPI Tester
A single undocumented change to an API response can quietly break every downstream integration that depends on it, and by the time a partner or a mobile app notices, the trust cost is already paid. This service builds automated contract and integration testing across your endpoints — functional behavior, edge cases, and third-party dependencies — so breaking changes get caught in a build, not in a partner's inbox. It's for teams shipping public or partner-facing APIs, or running enough microservices that manual spot-checks stopped being reliable. The result is a regression suite that fails the build the moment a contract breaks, instead of waiting for someone downstream to notice.
How We’d Approach This
A clear, staged plan — not a black box
- 1
Map existing endpoints, consumers, and integration points to find where contract breaks have caused problems before.
- 2
Build automated test coverage for the highest-traffic or highest-risk endpoints first, as a pilot for the full suite.
- 3
Review test results and contract definitions with API owners and consuming teams to close any gaps in shared understanding.
- 4
Expand coverage to the full endpoint surface and wire it into CI so a broken contract blocks the build, not the customer.
What You Get
