Hey everyone 👋


I’ve been exploring API testing services lately and wanted to get some insights from the community.


From what I understand, API testing is all about validating whether APIs work correctly in terms of functionality, performance, security, and reliability by sending requests and checking responses . Since modern apps rely heavily on APIs, even small issues at the API layer can break entire systems.


💡 Why API testing services matter​


  • Helps detect bugs early (even before UI is ready)
  • Faster and more efficient than UI testing
  • Ensures secure and stable integrations
  • Supports automation and CI/CD pipelines

🚀 What I found useful​


I came across this detailed guide on API testing services .


It explains how modern tools (especially AI-driven ones) can automate API test generation and improve coverage without writing tons of manual test cases.


🤔 My questions:​


  • What API testing services/tools are you currently using?
  • Do you prefer automated API testing or manual testing?
  • Has anyone tried AI-based tools like Keploy for API testing?
  • How do you handle testing in microservices architecture?

Would love to hear real-world experiences and recommendations 🙌
