Integrating the SaaS Application in Azure AD

Is anyone successfully done the simulation of integrating SaaS application in Azure AD ?1 i tried earlier and could not succeed .  i struck in things like SSO settings .  I guess we need some Application parameter that has to come from Application vendor , not sure about it . 

My objective is to simulate the application integration and publish it in Myapps portal , so that test user can access the published application successfully  . If any one tried and succeed earlier please assist me . Thanks in advance . 

This is my first message in this forum . I believe i will get the expert help
