Hi,

I am using dynamic 365 version 9.0.1. It is a sandbox instance.

I am using web service in plugin to get some data in CRM.

Webservice : http://dev.xxxxx-systems.com:7047/DynamicsNAV90B49326-02/WS/xxxxx%20Pvt%20Ltd/Codeunit/CRMManagement

Web service IP address is accessible publicaly and also give DNS.

Code :

CRMManagement.Credentials = new System.Net.NetworkCredential("xxxxxxx", "xxxxxxx", "xxxxxxxxxx");
CRMManagement.Url = "dev.xxxxxx-systems.com/.../CRMManagement";

CRMManagement.GetSalesPrice_gFnc(customer_no, item_no, uom_code, orderline.CreatedOn.Value, currency_code, ref unitPrice);

I have used same web service in crm2016. It is working fine.

Thanks,

keyur shah.

EDIT: This is incorrect suggestion, apologies for the confusion.

Hello,

All plug-ins in Dynamics 365 Online run in an isolation sandbox, which limits your capabilities for security purposes.

You are unfortunately not allowed to use non-standard port numbers, I see you are using 7047 ( http ://dev.xxxxx-systems.com : 7047 ), which is not allowed.

You are only allowed to use port 80 for HTTP or port 443 for HTTPS as standards define.

Please refer to this article about the isolation and limitations of plug-ins in Dynamics 365, specifically the section "Web Access":

https://docs.microsoft.com/en-us/dynamics365/customer-engagement/developer/plugin-isolation-trusts-statistics#web-access

Hi Keyur,

You wont be able to access Web service having IP address. You need to host that service and also you need domain name for your service then only it will work. I had this issue in past.

Best Regards,

Shahbaaz

Hi Keyur,

What is the authentication you have used ?

As you cannot use integrated windows authentication inside a sandboxed plugin.

Please try with HttpProxyCredentialType.Basic .

Please check HttpProxyCredentialType reference -

referencesource.microsoft.com

Hi Goutam,

I have to use this web service like this. I already used in past.

Hi All,

I got solution.

We are using .net framework 4.5.2.

Now We are change to .net framework 4.6.2 for dynamic 365 v9.0 and it is working fine.

: We can use windows authentication for web service with sandbox plugin.

Thanks,

keyur shah.

Hi Keyur,

I'm facing similar issue. Through web service we are getting details like customer name , mail id passing the mobile number of customer. This was working fine in 8.2 version. After upgrading to version 9 it is not working in dev and uat environment. It is working properly in production environment as it is still in version 8.2. If we just change framework to 4.6 and add latest dll and reregister it is enough. The original plugin is working , only to get customer details it is not working as we use webservcies

Rebuild this assembly using .NET Framework version 4.5.2 and try again. when i change framework back to 4.5.2 i'm able to register the plugin. I'm not able to get the required output.
