We have a web app (ASP.Net) published on Azure and we connected the web app with CRM Dynamics 365 on Azure Active Directory.

We followed this tutorial https://debajmecrm.com/2016/02/29/dynamics-crm-web-api-external-application/ and we were able to retrieve records from crm using this method:

{var webRequest = (HttpWebRequest)WebRequest.Create(new Uri("https://XXX.crm.dynamics.com/api/data/v8.0/accounts?$select=name,address1_city&$top=10"));
webRequest.Method = "GET";
// webRequest.ContentLength = 0;
webRequest.Headers.Add("Authorization", String.Format("Bearer {0}", authResult.AccessToken));
webRequest.Headers.Add("OData-MaxVersion", "4.0");
webRequest.Headers.Add("OData-Version", "4.0");
webRequest.ContentType = "application/json; charset = utf-8";
using (var response = webRequest.GetResponse() as System.Net.HttpWebResponse)
{
//Get reader from response stream
using (var reader = new System.IO.StreamReader(response.GetResponseStream()))
{
var accounts = new List<Account>();
string responseContent = reader.ReadToEnd();

dynamic dynamicObj = JsonConvert.DeserializeObject(responseContent);

foreach (var data in dynamicObj.value)
{
var account = new Account
{AccountName = data.name.Value,
City = data.city != null ? data.city.Value : string.Empty};

accounts.Add(account);}

Now i want to update record in crm using the same method(HttpWebRequest). How can i do that?

To retrieve data from an entity you are updating you can compose your PATCH request so that data from the created record will be returned with a status of 200 (OK). To get this result, you must use the return=representation preference in the request headers.

To control which properties are returned, append the $select query option to the URL to the entity set. The $expand query option will be ignored if used.

This example updates an account entity and returns the requested data in the response.

Request

HTTPCopy

PATCH [Organization URI]/api/data/v9.0/accounts(00000000-0000-0000-0000-000000000001)?$select=name,creditonhold,address1_latitude,description,revenue,accountcategorycode,createdon HTTP/1.1 OData-MaxVersion: 4.0 OData-Version: 4.0 Accept: application/json Content-Type: application/json; charset=utf-8 Prefer: return=representation {"name":"Updated Sample Account"}

Response

HTTPCopy

HTTP/1.1 200 OK Content-Type: application/json; odata.metadata=minimal Preference-Applied: return=representation OData-Version: 4.0 { "@odata.context": "[Organization URI]/api/data/v9.0/$metadata#accounts/$entity", "@odata.etag": "W/\"536537\"", "accountid": "00000000-0000-0000-0000-000000000001", "accountcategorycode": 1, "description": "This is the description of the sample account", "address1_latitude": 47.63958, "creditonhold": false, "name": "Updated Sample Account", "createdon": "2016-09-28T23:14:00Z", "revenue": 5000000.0000, "_transactioncurrencyid_value": "048dddaa-6f7f-e611-80d3-00155db5e0b6" } I hope this helps!

Hello,

Please refer to this sample code found in: http://himbap.com/blog/?p=2043

var crmUrl="xxx"; var contactId var contact = {}; contact["description"] = "xxx"; contact["emailaddress1"] = "xxx"; var req = new XMLHttpRequest(); req.open("PATCH", crmUrl "/api/data/v8.0/accounts(" contactId ")", true); req.setRequestHeader("Accept", "application/json"); req.setRequestHeader("Content-Type", "application/json; charset=utf-8"); req.setRequestHeader("OData-MaxVersion", "4.0"); req.setRequestHeader("OData-Version", "4.0"); req.onreadystatechange = function () { if (this.readyState == 4) { req.onreadystatechange = null; if (this.status == 204) console.log("contact is updated"); } else { var error = JSON.parse(this.response).error; console.log(error.message); } } req.send(JSON.stringify(contact));

Additionally, you need to add your access_token in the request header.
