Report download using HTTPClient still gives an Error "Missing client information"

[Michael D]

Hey,

I tried to get some reports, but I get the following Error:

"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>
<reportDownloadError>
<ApiError>
<type>ReportDownloadError.INVALID_PARAMETER</type>
<trigger>Missing client information</trigger>
<fieldPath></fieldPath>
</ApiError>
</reportDownloadError>"

This is my code:

 var client = new HttpClient();

            var postRequest = this.ConstructPostRequest();
            var content = new StringContent(postRequest, Encoding.UTF8, "application/x-www-form-urlencoded");

            client.DefaultRequestHeaders.TryAddWithoutValidation("Authorization:", "Bearer " + accesToken);
            client.DefaultRequestHeaders.TryAddWithoutValidation("developerToken: ", developerToken);
            client.DefaultRequestHeaders.TryAddWithoutValidation("clientCustomerId: ", clientCustomerId);

            var request = new HttpRequestMessage(HttpMethod.Post, baseAdressAdWords)
            {            
                Content = content
            };
           
            var response = client.SendAsync(request).Result;
           
            var responseString = response.Content.ReadAsStringAsync().Result;
        }

        private string ConstructPostRequest()
        {
           
             string xml=@"<reportDefinition xmlns=""https://adwords.google.com/api/adwords/cm/v201409"">
                  <selector>
                    <fields>CampaignId</fields>
                    <fields>Id</fields>
                    <fields>Impressions</fields>
                    <fields>Clicks</fields>
                    <fields>Cost</fields>
                    <predicates>
                      <field>Status</field>
                      <operator>IN</operator>
                      <values>ENABLED</values>
                      <values>PAUSED</values>
                    </predicates>
                  </selector>
                  <reportName>Custom Adgroup Performance Report</reportName>
                  <reportType>ADGROUP_PERFORMANCE_REPORT</reportType>
                  <dateRangeType>LAST_7_DAYS</dateRangeType>
                  <downloadFormat>XML</downloadFormat>
                </reportDefinition>";

             return "__rdxml="+ System.Net.WebUtility.UrlEncode(xml);
        }

Does anyone know what Im doing wrong?

Thank you very much.

Solved :)

            var client = new HttpClient();

            var postRequest = this.ConstructPostRequest();
            var content = new StringContent(postRequest, Encoding.UTF8, "application/x-www-form-urlencoded");

            var request = new HttpRequestMessage(HttpMethod.Post, baseAdressAdWords)
            {            
                Content = content,
            };
            request.Headers.Add("Authorization", "Bearer " + accesToken);
            request.Headers.Add("developerToken", developerToken);
            request.Headers.Add("clientCustomerId", clientCustomerId);
            var response = client.SendAsync(request).Result;
           
            var soapResponse = response.Content.ReadAsStringAsync().Result;

            return soapResponse;

        }

        private string ConstructPostRequest()
        {
           
             string xml=@

"<reportDefinition>

;

             return "__rdxml="+ System.Net.WebUtility.UrlEncode(xml);
        }
