Customize entity metadata
Applies to Dynamics 365 (online), version 9.x
Entities are defined by metadata. By defining or changing the entity metadata, you can control the capabilities of an entity. To view the metadata for your organization, use the metadata browser. Download the metadata browser.
More information: Browse the Metadata for Your Organization
This topic is about how to work with entities programmatically. See Create or edit entities (record types) for information about working with entities in the application.
Entities can be created using either the Organization service or the Web API. The following information can be applied to both.
- With the Organization service you will use the EntityMetadata class. More information: Create a custom entity and Retrieve, update, and delete entities
- With the Web API you will use the EntityMetadata EntityType. More information : Create and update entity definitions using the Web API.
Entity metadata operations
How you work with entity metadata depends on which service you use.
Since the Web API is a RESTful endpoint, it uses a different way to create, retrieve, update, and delete metadata. Use
DELETE HTTP verbs to work with metadata entitytypes. More information : Create and update entity definitions using the Web API.
One exception to this is the RetrieveMetadataChanges Function provides a way to compose a metadata query and track changes over time.
If working with Organization Service, use RetrieveMetadataChangesRequest class. This class contains the data that is needed to to retrieve a collection of metadata records that satisfy the specified criteria. The RetrieveMetadataChangesResponse returns a timestamp value that can be used with this request at a later time to return information about how metadata has changed since the last request.
|Message||Web API||SDK Assembly|
|CreateEntity||Use a POST request to send data to create an entity.||CreateEntityRequest|
|DeleteEntity||Use a DELETE request to delete an entity.||DeleteEntityRequest|
|RetrieveAllEntities||Use GET request to retrieve entity data.||RetrieveAllEntitiesRequest|
|UpdateEntity||Use a PUT request to update an entity.||UpdateEntityRequest|
Used together with objects in the Microsoft.Xrm.Sdk.Metadata.Query namespace to create a query to efficiently retrieve and detect changes to specific metadata. More information: Retrieve and Detect Changes to Metadata.
