API Testing Use Case

“We need to test this third-party app, but we don’t control its development. How do we do it?” 

 This is a question I hear often during integration projects. 

Recently, a client was rolling out a new internal system that had to work seamlessly with a third-party tool. The challenge? 

• The vendor updated their UI frequently. 

• No advance notice of changes. 

• Our automation scripts kept breaking. 

So, what’s the solution?  

Shift the focus from UI to APIs. 

APIs are the backbone of these integrations. They’re far more stable than the UI, and they allow us to validate data flow and business logic without worrying about cosmetic changes. By automating API tests, we: 

• Reduce maintenance headaches. 

• Ensure faster, more reliable integration testing. 

• Keep pace with evolving third-party systems. 

Pro Tip: Use API testing as your foundation and add minimal UI checks for critical workflows. This hybrid approach gives you coverage without the chaos.
