Mobile testing and capturing traffic

Dear all,

I need help 😉 At the time of this message, I test a mobile app manually and with Fiddler I inspect resquest/response from my app. Sometimes I have to change de body of the request/response to observe the consequence on the app (with Fiddler). 

But I need to know if this process is possible with Testcomplete or an other product of the Smartbear collection ? This is what I need in a simple words : 

- Launch tested app and capture all the https traffic

- the captured traffic need to be inspect and compare to a reference. 

- I need to have some https resquest/response body changed to inject them when the app start.

- And obviously, the most automatic way possible.

Thanks to everyone who will read me and help me.
