Report Embed to App for Customers

[d_u_a]

I have some questions that i didn't understand clearly from documentation. 

1) I 'm using Power Bi Pro with my company mail . Currently i can't access to our company Azure Active Directory with my company mail (asada@companyname.com) because of security process so I opened an Azure acount with my individual account (asadasds@outlook.com) and i will create an app in azure to get accessToken to embedding . 
My question : My Power Bi Pro acoount mail (company mail) is different from Azure account mail (individual mail) , Is it a problem for embedding my reports ? Should two mail be the same in Azure and Power Bi Pro account to embed my reports?

2)When embedding reports to App for customer can i use only Javascript Api or should i use Rest api and Javascript Api together ?
I made a demo project with using this link :  https://microsoft.github.io/PowerBI-JavaScript/demo/v2-demo/index.html  .
So i only used Javascript Api but if i develop for my customer is it enough to use Javascript Api like this example ?

Hi @d_u_a,

I think they are complementary. The Javascript SDK have more interactive functions while the REST API has more administrative functions. For example, we need to use groups_adduserasadmin to add a user to the App workspace. We can use PowerBI-JavaScript Bookmarks to operate the bookmarks. 

Please refer to api/power-bi/ and PowerBI-JavaScript/wiki.

Best Regards,

Dale
