Can we append URL parameters to an endpoint based on values in a test case?

Is it possible to send input parameters to the chatbot from test cases, both with and without user input? What I have in mind is that I should be able to do this in the test cases:

Test case 1 

#me
Hello
INPUT_PARAMETER sttConfidence : 0.58
INPUT_PARAMETER callerCountry : GB

#bot
Hi human! I see that you sent some input parameters. Thank you!
...
...

The input parameters need to be appended to the endpoint, so the URL would look like this:

https://MyChatBotsEndpoint.com/?userinput=&sttConfidence=0.58& callerCountry=GB

The values that we send need to be of type string.

Is this possible to achieve in Botium? And if yes, are there any native tools in Botium that can achieve this, or do we need to develop our own function?
