Well, the title is self descriptive, but here's my issue again:
I have a SharePoint Online which I've managed attach some event receiver to one of it's list, now after this is successfully done, i need to call an external web service (WCF) from that event receiver but i can't (I get "No endpoints were found for serivce . . .")
Does anyone know how to do this.
I'm pretty new to SPO, so any help would be appreciated.
Thank you.
Best regards.
Edit: The solution is not Provider-hosted, it's a SharePoint App and as for the WCF service it is hosted on some public server of our's (Not SharePoint hosted)
