Entity attribute metadata messages
An entity attribute is a container for a piece of data in an entity. In this developer guide, the term “attribute” and “property” (class property) are often used interchangeably with the term “entity attribute.” The Dynamics 365 Customer Engagement (on-premises) application uses the term “field” when it refers to entity attributes.
Note
It is possible to create and update entity attributes using the Web API. See Create attributes using Web API for more details.
