Hello Guys
We are now new to support Dynamics platform . To change order status in Dynamics , we used XRM tool box and it worked fine. But when trying to automate using WebAPI Call it throws error Object Reference not set to instance of object.
Can you please help me to resolve this issue??

Hi,
Use below C# web api code to update status of order. Make sure you pass correct Statecode and statuscode integer values. Combinations should be correct.
using (HttpClient httpClient = new HttpClient()) { httpClient.BaseAddress = new Uri(Resource); httpClient.Timeout = new TimeSpan(0, 2, 0); httpClient.DefaultRequestHeaders.Add("OData-MaxVersion", "4.0"); httpClient.DefaultRequestHeaders.Add("OData-Version", "4.0"); httpClient.DefaultRequestHeaders.Accept.Add( new MediaTypeWithQualityHeaderValue("application/json")); httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", _authResult.AccessToken); //update order status JObject updateOrder = new JObject { {"statecode", 0}, {"statuscode", 2} }; HttpResponseMessage updateResponse = await httpClient.SendAsJsonAsync(new HttpMethod("PATCH"), "api/data/v8.2/salesorders(" salesorderid{replace with guid of order} ")", updateorder); }
Please find below link which has sample Web API c# code to perform basic operations in CRM.
