Extend Dynamics 365 for Customer Engagement on the client
Applies to Dynamics 365 for Customer Engagement apps version 9.x
Client extensions can provide a very rich and responsive experience for users because the code runs on their device. However, critical business logic should not be applied only by client-side scripts. Unlike extensions that are applied on the server, client extensions can’t apply business logic for data entering the system by other means, such as integrations with other systems, custom clients, or data import.
