Hi all.

I'm facing a Permission error when i try to call an external WebService from my plugin.

Notes:
1. The web service was developed by another company and they said that they could not put a friendly name (dns) for this url
2. The web service is on IP format (http://200.279.18......).

So, for a temporary solution, i did a Windows Scheduler console APP that runs every 1min calling the Web Service and update the Quote entity. But i need this web service executing on real time.

Any help?

A couple of questions

1. Which version of CRM are you using? How is the plugin registered?

2. Is your CRM tenant using https? If yes, a call to a http service will be blocked, due to security issues.

What kind of errors,

Can you write here the text of the error catched in your Plugin?

Otherwise if it works in a console app, so it can work in a plugin.

Best Regards,

System.Security.SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I don't know if your affirmative is correct, because the Console App is executing on my windows server and the plugin executes from cloud (SandBox).

You can't use an IP address when calling a web service from a plug-in in CRM Online - needs a DNS name

@Jason Lattimer

Thanks, i didn't see this page before.

I will try to do a intermediary Web Service, it will be:

1. Plugin call my custom Web Service

2. My Web Service call the another company Web Service.

If it works, i will answer here.

I'm sorry, i forgot to answer here.

Yes, the solution below works well considering that the company can't put a DNS on their web service ip adress

1. Plugin call my custom Web Service

2. My Web Service call the another company Web Service.
