Form Digest issue in SharePoint REST API

In this article we will discuss about SharePoint Form Digest issue in REST API. At the time of POST event in SharePoint REST API, we have to pass  "X-RequestDigest": jQuery("#__REQUESTDIGEST").val();  but it seems, some time jQuery("#__REQUESTDIGEST").val(); returns noting(undefined).

 So, in this case we can use below code to get Form Digest and can use in our JavaScript code instead of jQuery("#__REQUESTDIGEST").val();


   var hostUrl = "http://mycompany.sharepoint.com/sites/site1/SharePoint/oAuth";
   function getFormDigest() {
    $.support.cors = true;
    var _formDigest;
    $.ajax({
        url: hostUrl + "/_api/contextinfo",
        type: "POST",
        dataType: "json",

      headers: { "Accept": "application/json; odata=verbose" },
        xhrFields: { withCredentials: true },
        async: false,
        success: function (data) {
            _formDigest = data.d.GetContextWebInformation.FormDigestValue;
        },
        error: function () {
            console.log("Error Occured");
         }
    });

    return _formDigest;
   }

Using ExecuteMultiple and Upsert Request in C#

ExecuteMultiple in Dynamics 365 is used to execute multiple requests, at the same time.  

In Dynamics 365, we can insert or update request in a single request that is called Upsert. 

Now here we are using a scenario for applying ExecuteMultiple and Upsert Request in a single request.

Here I have created a key inside Contact entity with the name  ”sam_myerpid”. I have mapped ”sam_myerpid” with “ContactId”.

Code: - 

            ///Creating a list

            List<Customer> customers = new List<Customer>();

            customers.Add(new Customer() { id = 1, firstname = "Sam", lastname = "Khan" });

            customers.Add(new Customer() { id = 2, firstname = "Michel", lastname = "Andrew" });

            customers.Add(new Customer() { id = 3, firstname = "Robert", lastname = "Grew" });

            ///Define ExecuteMultipleRequest

            ExecuteMultipleRequest multipleRequest = new ExecuteMultipleRequest()

            {

                Settings = new ExecuteMultipleSettings()

                {

                    ContinueOnError = true,

                    ReturnResponses = true

                },

                Requests = new OrganizationRequestCollection()

            };

            

            foreach (var cust in customers)

            {

                //Define and add value to KeyAttributeCollection

                KeyAttributeCollection keyColl = new KeyAttributeCollection();

                keyColl.Add("sam_myerpid", cust.id.ToString());

                ///Define Entity and pass KeyAttributeCollection

                Entity custEntity = new Entity("contact", keyColl);

                ///Map fields data

                custEntity.Attributes["firstname"] = cust.firstname;

                custEntity.Attributes["lastname"] = cust.lastname;

                ///Define UpsertRequest

                UpsertRequest req = new UpsertRequest()

                {

                    Target = custEntity

                };

                ///Add UpsertRequest to ExecuteMultipleRequest

                multipleRequest.Requests.Add(req);

            }

            ///Execute

            ExecuteMultipleResponse multipleResponse = (ExecuteMultipleResponse)service.Execute(multipleRequest);

Screenshot: -

So now after execute, this request It will insert records and if there are already records with same ”sam_myerpid” then it will update that records.
