API Testing
Rigorous validation of REST, GraphQL, and SOAP endpoints for security, payload structure, and performance.
Why API Testing Matters
Validate REST and API integrations for functionality, data accuracy, authentication, error handling, and reliability.
Tools & Technologies We Use
What We Test
What This Looks Like In Practice
New Endpoint Contract Validation
Before a new endpoint ships, we validate the request/response schema, required vs. optional fields, and status codes against the OpenAPI spec, not just a single happy-path call.
Authorization Boundary Testing
We call every endpoint as a lower-privileged role to confirm data scoped to another tenant or user can't be reached - a class of bug a UI-only test would never surface.
Third-Party Integration Failure Handling
We simulate a payment gateway timing out or returning a server error, and verify your API degrades gracefully instead of leaving an order in a broken, half-completed state.
What You Walk Away With
Why We're a Good Choice for API Testing
APIs fail quietly - a wrong status code or a malformed payload can pass a surface check and still break every client that depends on it. We test contracts, schemas, and negative/edge cases as rigorously as the happy path, and we build automated API regression suites that run on every change, so backend defects get caught before they surface as a frontend bug three teams removed.
Common Questions About API Testing
Do you test GraphQL as well as REST and SOAP APIs?+
Yes - we test REST, SOAP, and GraphQL APIs, including query/mutation validation and schema correctness for GraphQL specifically, not just standard REST endpoint checks.
How do you test authentication and authorization on our APIs?+
We validate token handling, session expiry, and authorization boundaries directly - including attempts to access endpoints or data a given role shouldn't be able to reach.
Can you set up automated API regression suites we can run on every deploy?+
Yes - building automated, CI-integrated API regression suites (typically with Postman/Newman or RestAssured) is a standard part of this service, so backend changes get regression coverage on every build.
