Posted on by Eduteam srl 35

I am getting status 400 error while creating record in Crm its post method, for get method its working fine, in crm restbuilder its working fine to create record.

string resource = "https://*****.crm4.dynamics.com/";
UserCredential clientredentials = new UserCredential("****t@******onmicrosoft.com", "****@716");
string client_id = "2b572be0-*****-4581-8481-*******";
AuthenticationContext authenticationContext = new AuthenticationContext("">login.microsoftonline.com/.../authorize");
AuthenticationResult authenticationResult = authenticationContext.AcquireToken(resource, client_id, clientredentials);
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
HttpClient httpClient = new HttpClient();
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", authenticationResult.AccessToken);
httpClient.BaseAddress = new Uri("">orgf65ea8ad.api.crm4.dynamics.com/.../");
account_creation_1 ac_1 = new account_creation_1()
{
name = account_Creation.name,
preetham_reasonforregistration = account_Creation.reason_for_registration,
preetham_DepartmentId = Guid.Parse(account_Creation.Department),
preetham_doctorId = Guid.Parse(account_Creation.Doctor)
};


HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post,new Uri("https://*****.api.crm4.dynamics.com/api/data/v9.2/accounts"))
{
Content = new StringContent(ac_1.ToString(), Encoding.UTF8, "application/json")
};
var response = httpClient.SendAsync(request, HttpCompletionOption.ResponseContentRead).Result;
if (response.IsSuccessStatusCode)
{
Console.Write("Account Created");
}
}

    Hi,

    httpClient.BaseAddress = new Uri("">orgf65ea8ad.api.crm4.dynamics.com/.../");

    right string of "">?

    Hi, please share what the error says, 

    The Uri for the request should only be the entityNameSet ("accounts","leads",etc..) because your are setting a "BaseAddress" property for you HttpClient Class.

    Also I'd use NewtonJson for converting the account_creation_1 to JSON format, doing this "Content = new StringContent(ac_1.ToString(), Encoding.UTF8, "application/json");" doesn't pass a valid JSON payload.

    for testing purposes in connection to microsoft dataverse take a look of the samples in their Official repo at PowerApps-Samples

    I made SolutionContainer a solution repo base on PowerApps-Samples, where your just clone and play change just this fields by your own.

    private static readonly string Url = "https://contoso.crm.dynamics.com";
private static readonly string ClientId = "00000000-0000-0000-0000-000000000001";
private static readonly string UserName = "USER@contoso.onmicrosoft.com";
private static readonly string Password = "YOUR_PASSWORD";

    here Oficial documentation Docs

    regards.

    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post,new Uri("accounts")) //<--when i changed this got error of invalid url

    preetham_DepartmentId = Guid.Parse(account_Creation.Department),//<-- if this is lookup the fortmat should be "fieldname@odata.bind = entityname_in_plural(GUID)"

    preetham_doctorId = Guid.Parse(account_Creation.Doctor)//<--yes this is lookup

    but now i had removed, now i am just testing with one field "name" but still got the same error

     account_creation_1 ac_1 = new account_creation_1()

                   {

                       name = account_Creation.name

                   };

                   HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post,new Uri("orgf65ea8ad.api.crm4.dynamics.com/.../accounts"))

                   {

                       Content = new StringContent(ac_1.ToString(), Encoding.UTF8, "application/json")

                   };

                   var response = httpClient.SendAsync(request, HttpCompletionOption.ResponseContentRead).Result;

    still the same error

    Hi Eduteam,

    I'd change this lines

    Payload

    account_creation_1 ac_1 = new account_creation_1()
{
name = account_Creation.name,
preetham_reasonforregistration = account_Creation.reason_for_registration,
preetham_DepartmentId = Guid.Parse(account_Creation.Department),//<-- if this is lookup the fortmat should be "fieldname@odata.bind = entityname_in_plural(GUID)"
preetham_doctorId = Guid.Parse(account_Creation.Doctor)//<-- if this is lookup the fortmat should be "fieldname@odata.bind = entityname_in_plural(GUID)"
};

    URI

    //wrong
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post,new Uri("https://*****.api.crm4.dynamics.com/api/data/v9.2/accounts"))
//good
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post,new Uri("accounts"))

    Check for lookup data WebAPi
