I want to call Rest api which is not of SharePoint. I have created one Api which is in php. And I want to call that api in my SharePoint hosted App.
Is it possible to call API which not of SharePoint in SharePoint hosted app?
Because when I tried to call API to my app it throw error : Access Denied.!.
Any suggestions..?!
This problem is due to the fact that SharePoint only allows out of the box REST & CSOM endpoints consumption from Apps so if you deploy custom WCF services, it won't be allowed from within the App.
If you use sp.webrequestinfo cross-domain library, you'll notice that it will work providing your service is consumable anonymously. Remember that in the context of a SharePoint-Hosted App, your only ways to consume web services are: 1. with JavaScript 2. using an External Content Type but that only works for data services and I'm not sure that it works if your service requires authentication.
So, given the above, one way to achieve our goal is to use CORS but it will require some extra efforts before it works.
