This is also what I use. Others mention insomnia, but it does not support testing responses (validating them) with a script. With the Http Client in IntelliJ you can do that, as well as with Postman. But with Postman you need to import/export everything and put it into you projects, so you can check it in with your source code. Using IntelliJ you don't need to do that anymore too.

Having used Postman, Insomnia and the IntelliJ Http Client, the last one is the best out of them all.
