Retrieves the metadata for the specified entity.

The relevant classes are specified in the following table.



To perform this action, the caller must be a user in the organization for which metadata is requested and must have Read Attribute, Read Entity and Read Relationship privileges.


The following example shows how to use the RetrieveEntity message.

// Create an authentication token.
CrmAuthenticationToken token = new CrmAuthenticationToken();
token.OrganizationName = "AdventureWorksCycle";

// You can use enums.cs from the SDK\Helpers folder to get the enumeration for Active Directory authentication.
token.AuthenticationType = 0; 

// Create the metadata Web service;
MetadataService metadataService = new MetadataService();
metadataService.Url = "http://<servername>:<port>/MSCRMServices/2007/MetadataService.asmx";
metadataService.CrmAuthenticationTokenValue = token;
metadataService.Credentials = System.Net.CredentialCache.DefaultCredentials;
metadataService.PreAuthenticate = true;

// Create the request
RetrieveEntityRequest entityRequest = new RetrieveEntityRequest();
// Retrieve only the currently published changes, ignoring the changes that have
// not been published.
entityRequest.RetrieveAsIfPublished = false;
entityRequest.LogicalName =;
entityRequest.EntityItems = EntityItems.EntityOnly;
// Execute the request
RetrieveEntityResponse entityResponse = (RetrieveEntityResponse)metadataService.Execute(entityRequest);
// Access the retrieved entity
EntityMetadata retrievedEntityMetadata = entityResponse.EntityMetadata;
[Visual Basic .NET]
' Set up the CRM Service.
Dim token As New CrmAuthenticationToken()
' You can use enums.cs from the SDK\Helpers folder to get the enumeration for Active Directory authentication.
token.AuthenticationType = 0
token.OrganizationName = "AdventureWorksCycle";

// Create the metadata Web service.
Dim metadataService As New MetadataService ()
metadataService.Url = "http://<servername>:<port>/mscrmservices/2007/MetadataService.asmx";
metadataService.CrmAuthenticationTokenValue = token;
metadataService.Credentials = System.Net.CredentialCache.DefaultCredentials
metadataService.PreAuthenticate = true;

' Create the request.
Dim entityRequest As New RetrieveEntityRequest()
entityRequest.RetrieveAsIfPublished = True
entityRequest.LogicalName =
entityRequest.EntityItems = EntityItems.EntityOnly

' Execute the request.
Dim entityResponse As RetrieveEntityResponse = CType(metadataService.Execute(entityRequest), RetrieveEntityResponse)

' Access the retrieved entity.
Dim retrievedEntityMetadata As EntityMetadata = entityResponse.EntityMetadata

'#Region "check success"

If retrievedEntityMetadata.SchemaName <> "Contact" Then
   success = False
End If
