Backend changes silently break clients that depend on the API, and nobody notices until support tickets come in.
Service
API testing that catches breakage before your users do.
We validate your REST and GraphQL endpoints directly, checking contracts, edge cases, and failure handling, so integration bugs get caught before they ever reach a UI. Coverage is scoped during discovery to the endpoints your product actually depends on.

Why teams come to us
What this service helps you solve
Error responses and edge cases go untested because most manual testing only exercises the UI's happy path.
Third-party or service-to-service integrations fail under load or unexpected input with no automated safety net.

Final roles are recommended after discovery.Discovery before SOW
Discovery comes before every reliable statement of work.
Before we recommend roles, timelines, or pricing, we need to understand your goals, technology stack, product situation, scope, risks, and constraints. Discovery helps us align expectations and create a realistic statement of work.

FAQ
Questions about this service
Yes, that's often the ideal time. Testing directly against the API before a frontend exists means we validate the contract early, and you avoid discovering backend issues only once the UI is built on top of them.
Both. We cover auth flows, role-based access, and authorization edge cases alongside standard request and response validation, since permission bugs are some of the costliest ones to miss.
We can run API testing as an embedded ongoing function alongside your backend engineers, or as a fixed-scope engagement to build out a test suite they then own. Discovery determines which model fits your team's bandwidth.
