I am working on the integration of adobe campaign( On-premise v7) with the Microsoft Dynamics CRM (Web API ), where I am facing the attached error.
Could you guys please help me on this and let me know in case of any information required to help on this.
Also I have one doubt that we are facing this error for the reason that one of solution is on-premise( adobe campaign) and another is on cloud ( Microsoft Dynamics)?
Your outgoing URL is not whitelisted.
For more information on how to configure it, refer to the Server configuration section of the Security configuration checklist document.Security configuration checklist
And of course, also in your firewall rules if you are On-Premise hosting...
If you need to use an external URL inside a workflow, then define an AC external account (Administration/Platform/External Accounts, create a new one, choose http to type an then type your https web service URL and select SSL security and if needed the credentials and port if not 443).
As stated in the error message, It seems you have to get it added this url to serverconf file.
