API Testing
Catch breaking changes before your clients do.
Functional, contract and integration testing for REST and GraphQL APIs — automated in CI so a backend change can't silently break web, mobile or partner integrations.
Sound familiar?
“Several clients depend on your APIs, and you find out about breaking changes from bug reports.”
A good fit if you have
- Microservice architectures
- Public or partner APIs
- Mobile apps that depend on backend stability

Questions
What people usually ask
Do you need access to our source code?
Not necessarily. API testing can be done black-box against a test environment, though contract testing benefits from code access.
