I have many users on my website its an educational portal where by students post about a subject area they are not good at and an instructor or an expert in that field then provide a solution for them .
So i wanted to know is there a way where i can use the google hang outs api to solve this solution .
This is what i want .

I want the lecturer or the expert to be able to invite the student for an interview / lecture at a specific date and time to attend a class from a widget on my website .
i already checked http://banckle.com/apis/default.html But that cant solve my problem very well
Please i need your feedback on this guys or if there is any other way i cas do that . I would really aopreciate it
Chers !
