ASP.NET Web API Usage with Dynamics Web Api

I’ve blogged about connection setup with the Dynamics Web API over the last little while – Getting it Setup and how to use with the USD.

One critical piece that I forgot (or rather overlooked) that needs to be mentioned is what is called the “Headless” connection.  This is a connection to your Dynamics tenant that does not use a Username or Password combination and does not prompt the user to enter in their credentials when accessing.

In my previous examples, my Application type was “native”, however, for this to work in a headless modality in a web api world, this needs to be configured as Web app / API.  If not configured this way, you will always be prompted for access to your Dynamics

Unified Service Desk and the Dynamics Web API

A follow-up to my post on Getting Started with the Dynamics Web API – on a recent project, I was building a custom hosted control in the USD that leveraged the Dynamics Web API.

However, when I went to deploy my control, my USD instance would implode and not load whatsoever.

Turns out the issue was a result of me using a higher version of the Microsoft.IdentityModel.Clients.ActiveDirectory dll (the latest 3.19) than what is supported in the USD (using 2.22).

The resolution was to downgrade my implementation of this dll to use 2.22 et voila, my solution deployed perfectly and my USD was no longer imploding.

I should note that for the above this is all done using v2 of the USD on a Dynamics 8.2 instance.

Saving data with the Dynamics Web Api

In my previous posts on using the Dynamics Web Api, I invested a significant amount of time in figuring out the connection protocols, querying and accessing data from the results (not being an Azure, Active Directory or JSON expert).

However, when it came to saving data, the hard work was over and I was able to do with relative ease.

To save data via the Dynamics Web API, the interface is quite similar to how you would access your controls via LateBinding except that instead of the Entity object you are consuming a JObject.

JObject phoneCall = new JObject();
 phoneCall["subject"] = "Here comes my call";
 phoneCall["phonenumber"] = "888-999-7777";
 phoneCall["scheduledend"] = DateTime.Now;
 phoneCall["description"] = "Who called me.";
//The Direction Code is always an incoming call.
 phoneCall["directioncode"] = false;

string recordId = string.Empty;
 try
 {
 HttpClient httpClient =

Retrieving Data with the Dynamics Web API

So after I worked that whole plural entity name thing on getting data from Dynamics, I now had my data coming back to me in a wonderful Json format.  When interacting with data from the Web API you query for information via the rest interface of your URL. (more on MSDN).

As an example, if I wanted to retrieve some information on a custom entity I could do it using this query syntax.

HttpResponseMessage response = await httpClient.GetAsync(dyanmicsTenant + "/api/data/v8.1/enc_medias?$select=dat_name,_dat_customer_value,dat_dataid&$filter=dat_name eq '" + SearchParameter + "'");

Which would return a Json package in the format of

{
"@odata.context":"https://myCrmTenant.crm.dynamics.com/api/data/v8.1/$metadata#datas(dat_dataid,dat_name)","value":[
{
"@odata.etag":"W/\"874140\"","dat_dataid":"fd95bfa1-ddb8-e711-8114-c4346bdcf161","_dat_customer_value":"{00665E23-779E-4C8C-A5D4-36213C41EA27}","dat_name":"0000000006"
}
]
}

A few things…

What is _dat_customer_value?

In my query, I wanted to get the lookup for a customerid, the field itself is called data_customerid, however, when accessing lookups you must prepend “_” to the field and append “_value” to the

Getting Started with the Dynamics Web API

The Dynamics Web API is the new “preferred” method for interacting with Dynamics entities from web-based applications.  If you are writing plugins and coded workflow activities, you would still use the pre-existing Dynamics SDK.

Getting familiar with the Web API is a bit of a leap of knowledge as you will dabble in Azure Authentication, JSON and Async implementations (if you’re not familiar with it).

Even though the API has been around since 2016, it’s disheartening to see there not being a singular location for Dynamics developers to bridge their current knowledge of the Dynamics SDK to the Web API.

Lots of trial and error still exists and this isn’t helped by the naming of the API either.

Also note, if you are hoping to get away with the now “vintage” Dynamics SDK, in
