we wanted customize our salesforce application via giving the skype conference link while sending the email from the application itself. the application is completely on visualforce pages and controller so i dont see any appexchange app will help on this.
I have already checked the below links though i could not get any integration apis https://msdn.microsoft.com/en-us/skype/ucwa/onlinemeetinginvitation_ref https://ucwa.skype.com/websdk
There are no integration Apis as of now. Only you have to write your own integration logic using Skype for Web SDK. It is a bit complicated SDK and not properly documented or maintained. It has tight coupling with Azure AD and video streaming doesn't work in Chrome/Firefox.
Some integration use cases/examples can be found here
