Calling Dataverse Web API functions

Single source of truth

To find all

  • entities, their attributes (columns) and relationships,
  • complex and enum types and
  • functions

available in your Dataverse environment, you may call the following endpoint:

https://org0.api.crm17.dynamics.com/api/data/v9.2/$metadata?annotations=true
Enter fullscreen mode Exit fullscreen mode

It will return xml document full of wisdom =)
You may find this endpoint in my Postman Beyond Microsoft Graph collection here: Single Source of Truth

Calling Dataverse functions

Let's assume we need to access documents attached to a Dataverse record. SharePoint integration is configured for this entity, so all the files are saved in a SharePoint site.
What we need to do now, is to find the location of all attached documents.

RetrieveAbsoluteAndSiteCollectionUrl

This can be accomplished using the RetrieveAbsoluteAndSiteCollectionUrl function.

After calling the metadata endpoint, I have access to the documentation for this function:

//...
<ComplexType Name="RetrieveAbsoluteAndSiteCollectionUrlResponse">
   <Property Name="AbsoluteUrl" Type="Edm.String" Unicode="false" />  
   <Property Name="SiteCollectionUrl" Type="Edm.String" Unicode="false" />
</ComplexType>
//...
<Function Name="RetrieveAbsoluteAndSiteCollectionUrl" IsBound="true">
   <Parameter Name="entity" Type="mscrm.sharepointsite" Nullable="false" />
   <ReturnType Type="mscrm.RetrieveAbsoluteAndSiteCollectionUrlResponse" Nullable="false" />
</Function>
<Function Name="RetrieveAbsoluteAndSiteCollectionUrl" IsBound="true">
   <Parameter Name="entity" Type="mscrm.sharepointdocumentlocation" Nullable="false" />
   <ReturnType Type="mscrm.RetrieveAbsoluteAndSiteCollectionUrlResponse" Nullable="false" />
</Function>
Enter fullscreen mode Exit fullscreen mode

Neat! 🚀

Note the IsBound="true" parameter and the fact that the <Function Name="RetrieveAbsoluteAndSiteCollectionUrl" is displayed twice. Bound functions can have multiple definitions when bound to different types.

This means that I can call the RetrieveAbsoluteAndSiteCollectionUrl with a reference to either sharepointsite or sharepointdocumentlocation.

Sharepoint Document Locations

Information about locations configured for the entity, or created for a record, can be obtained using sharepointdocumentlocations endpoint (line-breaks added for readability only):

https://org0.api.crm17.dynamics.com/api/data/v9.2/sharepointdocumentlocations?
 $select=
  sitecollectionid,
  _regardingobjectid_value,
  relativeurl,
  name,
  sharepointdocumentlocationid
 &$filter=
  _regardingobjectid_value eq '7399f668-90fc-4cf3-babb-75fa0c108486'
Enter fullscreen mode Exit fullscreen mode

which returns the following reponse:

{
    "@odata.context": "https://orgbb429a1a.api.crm17.dynamics.com/api/data/v9.2/$metadata#sharepointdocumentlocations(sitecollectionid,_regardingobjectid_value,relativeurl,name,sharepointdocumentlocationid)",
    "value": [
        {
            "@odata.etag": "W/\"8333355\"",
            "sitecollectionid": "fec93c89-fd02-ef11-9f89-6045bd2c4a3e",
            "_regardingobjectid_value": "7399f668-90fc-4cf3-babb-75fa0c108486",
            "relativeurl": "AAA_7399F66890FC4CF3BABB75FA0C108486",
            "name": "Documents on External Cloud Service Site 1",
            "sharepointdocumentlocationid": "42c244ad-a375-ef11-ac20-002248c9a7cb"
        }
    ]
}
Enter fullscreen mode Exit fullscreen mode

Calling RetrieveAbsoluteAndSiteCollectionUrl (I)

I will now call the RetrieveAbsoluteAndSiteCollectionUrl function with the sharepointdocumentlocation parameter, using the sharepointdocumentlocationid value returned in the previous step (line-breaks added for readability only):

https://org0.api.crm17.dynamics.com/api/data/v9.2/
 sharepointdocumentlocations(42c244ad-a375-ef11-ac20-002248c9a7cb)
/Microsoft.Dynamics.CRM.RetrieveAbsoluteAndSiteCollectionUrl()
Enter fullscreen mode Exit fullscreen mode

Important: When an function is bound, it will have a reference to a specific item within the service namespace. To use the function, you must use the fully qualified name including the Microsoft.Dynamics.CRM namespace.

It returns the following response:

{
    "@odata.context": "https://org0.api.crm17.dynamics.com/api/data/v9.2/$metadata#Microsoft.Dynamics.CRM.RetrieveAbsoluteAndSiteCollectionUrlResponse",
    "AbsoluteUrl": "https://contoso.sharepoint.com/sites/powerplatform/ENTITY_NAME/AAA_7399F66890FC4CF3BABB75FA0C108486",
    "SiteCollectionUrl": "https://contoso.sharepoint.com/sites/powerplatform"
}
Enter fullscreen mode Exit fullscreen mode

Calling RetrieveAbsoluteAndSiteCollectionUrl (II)

And what would happen if I used the sitecollection parameter?

https://org0.api.crm17.dynamics.com/api/data/v9.2/
 sharepointsites(fec93c89-fd02-ef11-9f89-6045bd2c4a3e)
/Microsoft.Dynamics.CRM.RetrieveAbsoluteAndSiteCollectionUrl()
Enter fullscreen mode Exit fullscreen mode

Same same, but different. In this case I only see the references to the SPO site configured in SharePoint integration settings for the entity, but of course there's no folder

{
    "@odata.context": "https://org0.api.crm17.dynamics.com/api/data/v9.2/$metadata#Microsoft.Dynamics.CRM.RetrieveAbsoluteAndSiteCollectionUrlResponse",
    "AbsoluteUrl": "https://contoso.sharepoint.com/sites/powerplatform",
    "SiteCollectionUrl": "https://contoso.sharepoint.com/sites/powerplatform"
}
Enter fullscreen mode Exit fullscreen mode

I already added these two calls to the Power Platform Environment folder in the Beyond Microsoft Graph collection.
Check it out to see them in action =)
