MSCRM – External Connector License

Integrating your CRM system with external world is a tricky business.  For example if you need to gather customer information from your website and populate in your CRM system as leads you need an external connector license. This License is required to view, manipulate and query data by non-CRM user. 

If you want to share Microsoft CRM data with external users such as your customers or partners, you can purchase an External Connector License that allows you to share Microsoft CRM data with an unlimited number of third-party users and systems.  

By using the External Connector License, you do not need to purchase a user license (create an Active Directory Account) for each external user. For example, you can create and external Web Site that lets customer log on and retrieve Microsoft CRM data real time. You could also create a special Web site for your partners to enter and update Microsoft CRM data. You need and External Connector license for every server required to support external access.

    well any application accesing data(create, update, select, delete) from crm needs external connector license.

    you can simply add web service reference and create web service object to fetch complete frame work api.

    Hi Ayaz,

    You said that any application that interacts with CRM requires an external connector license but there have been times that I’ve created applications windows as well as web that by accessing CRM’s web service accesses and edits CRM’s data without worrying about the connector license and stuff.
    Is something missing here? I guess, the information of the requirement of a connector license for accessing CRM’s database discussed in this forum incomplete. What say?

    Well, if your application is using one of the CRMr to access and edit data then its ok and no need for External connector license. But if you application is exposing data to public or not users of crm then you will have to go for external connector license.

    Even if you are creating a service that is synchronous and migrating data from crm database to your custom database, still you need an external connector license. For only services those who are not synchronous can transfer crm data to custom database for customer portals and service management.

    Can you clear something for me,

    I have a newsletter that people subscribe to on a CMS system that’s built in to our website (mysql db) We have just deployed CRM 4.0, so I took the data from the mysql and exported to CSV and imported to CRM- is there a way to automate this WITHOUT an external connector license?

    Well, as per my knowledge, External Connector License is not required when you import data to Dynamics CRM. You just use a user license with approperiate access to import data to Dynamics CRM. Exterbal Connector is required when you are moving CRM data to some otherdatabase synchronously or displaying CRM data to public.
