Hi Chhaya,

Yes, you can consuming web service from custom workflow activity or plugin.

There are 2 ways to do that in CRM Online.

1. You can host your web service in Azure server and then consume it via BasicHttpBinding.

2. If you host your service at your server, you have to consume it via IP of your server (also using BasicHttpBinding)

Also you should be to connect custom web services only if they are deployed on standard secured port 80 or 443. You can consume it in a standard way like in .net applications.

Thanks

Hi,

Plugin registered in CRM online runs into isolation mode "sandbox". Sandbox isolation mode has some limitations in web access to external resources.

Please check WEB ACCESS section in below link-

msdn.microsoft.com/.../gg334752.aspx

In CRM Online, you cannot access wcf service methods directly through IP address, you would need to assign a web address(URL) to the service and that web address will be used as pointer for your web service in plugin.

Best Regards,

Abhishek
