Creative ideas for testing REST API

[Maddy17]

Hello !

Now I have an Endpoint that I can retrieve it using Rest request with some mandatory parameters. I have java application that send the requests and I need to do test to this endpoint using my program.
Example:
I have a Rest api endpoint which is retrieved using GET request and 4 parameters: name, type ( has defined list) , id, and code .

So any creative ideas for testing ?

Thanks in advance !
