Update Datasource Credentials With OAuth2 using PowerBI Rest API on C#

Hello, 

I need to update a Datasource credential, inside a Workspace on Powerbi, inside a C# Project.

I'm using the PowerBI Rest API to do it, but when I try to update the Datasource Credentials, I get an error.

Error Body:
"... HTTP/1.1 400 Bad Request
{"error":{"code":"BadRequest","message":"Bad Request","details":[{"message":"The property 'oauthcredentials' does not exist on type 'Microsoft.PowerBI.ServiceContracts.Api.GatewayDatasource'. Make sure to only use property names that are defined by the type.","target":"datasourceDelta"}]}}"

 

My code :

var AccessToken = userAuthnResult.AccessToken;
string
 restUrlPatchCredentials = PowerBiServiceRootUrl + "gateways/" + gatewayToUpdate.gatewayId + "/" + "datasources/" + gatewayToUpdate.id; PBIDataSourceCredentials dataSourceCredentials = new PBIDataSourceCredentials {     credentialType = "OAuth2",     oauthcredentials = new PBICredentialData     {         accessToken = AccessToken     } };
string jsonDelta = JsonConvert.SerializeObject(dataSourceCredentials);

// add JSON to HttpContent object and configure content type HttpContent patchRequestBody = new StringContent(jsonDelta); patchRequestBody.Headers.ContentType = new MediaTypeWithQualityHeaderValue("application/json"); var method = new HttpMethod("PATCH"); var request = new HttpRequestMessage(method, restUrlPatchCredentials); request.Content = patchRequestBody; HttpClient client = new HttpClient(); clien.DefaultRequestHeaders.Add("Accept""application/json"); clien.DefaultRequestHeaders.Add("Authorization""Bearer " + AccessToken); var result = client.SendAsync(request).Result;

I think the error is the name of the "oauthcredentials" propriety, but i can't find the correct name.
Anyone having the same issue?

 

Thanks you!
