Posted on by Goutham A

I am using web api to retrieve records from multiple entities(which are added to a dynamic list).
i need the name of the entity in web api response to address business requirement. i see the request URL in @odata.context property.
Is there any way we can get the schemaname\displayname of the entity in web api response?

Hi,

I used this to get first the entitymetadataid by entityname: "/api/data/v8.2/EntityDefinitions?$filter=LogicalName%20eq%20'" + entityName + "'&$select=MetadataId"

With these EntityMetadataID you can get all Metadata from the entity like this: "/api/data/v8.1/EntityDefinitions(" + entityMetadataID + ")?$expand=Attributes"

Take a look in my question here: https://community.dynamics.com/crm/f/microsoft-dynamics-crm-forum/370899/retrieve-attributes-from-record-without-entitymetadataid

Hi Gowtham,

I thought you should create another function to retrieve entity's metadata with your current entity name variable by EntityDefinitions(LogicalName='xxx'),

then get its display name from callback result.

var Name = Xrm.Page.data.entity.getEntityName(); var record = retrieveEntityMetadata(Name); console.log(record["DisplayName"]["UserLocalizedLabel"].Label); function retrieveEntityMetadata(entityName) { var data = null; var req = new XMLHttpRequest(); req.open('GET', Xrm.Page.context.getClientUrl() "/api/data/v9.0/EntityDefinitions(LogicalName='" entityName "')", false); req.setRequestHeader("Accept", "application/json"); req.setRequestHeader("OData-MaxVersion", "4.0"); req.setRequestHeader("OData-Version", "4.0"); req.setRequestHeader("Prefer", "odata.include-annotations=*"); req.send(); if (req.readyState == 4 /* complete */ ) { if (req.status == 200) { data = JSON.parse(req.response); } else { var error = JSON.parse(req.response).error; console.log(error.message); } } return data; }

Result:

Syntax:

Attributes in entity's metadata:

Thanks Daniel!!

However, I am not looking at retrieving entitydefinitions.

The requirement is when i retrieve account records,from response ,how do i know that the records retrieved are of entity "Account"(and not contact)?

To elaborate, we have a drop down which lists all the entities(retrieved from metadata using entitydefinitions) and once we select a particular entity, we need to retrieve records for that entity based on some conditions. My question is , once we retrieved records of entity 'x', How to i know from response that the records are of type entity 'x'?

Hi Gowtham,

I thought "@odata.context" property would be actually what you want, as you mentioned it in your question.

You could search for the property description, it's context URL for entity.
