Common questions

Q: How long does API testing take?
Typically 2-4 weeks for a standard API with 20-50 endpoints. Complex systems with multiple services may take longer.
Q: Do you need access to our codebase?
No. We test from the consumer perspective using your API documentation and endpoints. Source code access is optional.
Q: What about internal/private APIs?
We can work within your VPN or set up secure tunnels. Our team is experienced with enterprise security requirements.
Q: Can you integrate with our CI/CD?
Yes. We deliver tests compatible with GitHub Actions, GitLab CI, Jenkins, CircleCI, and most other platforms.
