Would be nice if there was a way to record HTTP requests from the browser directly into HTTP objects, in a similar way Web recording does.
The workaround that I’m using for that is:
1- Use Postman interceptor to capture requests
2- Export Postman collection and use a tool (apimatic) to convert it to Swagger 2.0 spec
3- Import swagger spec into Katalon
4- Recreate all missing headers lost during conversion from Postman to Swagger
5- Create the test case manually using the imported requests
Both Postman and JMeter are able to capture the requests by firing up a local proxy that must be configured in the browser. If Katalon had that feature we would be able to design our API test cases a lot faster.
