Re: cannot download the report data and the message "MISSING_PARAMETER" appears

Hi,

For an XML report definition, the POST request body must contain a parameter named "__rdxml" whose value is your XML report definition. Your HTTP POST request should look something like this:

HTTP HEADER:

Authorization:Bearer xxxxxxxxxxxxxxxxxxxxxxxxxx
clientCustomerId:xxx-xxx-xxxx
Content-Type:application/x-www-form-urlencoded
developerToken:xxxxxxxxxxxxxxxxxxxxxxxx

Request Parameters:

__rdxml: <?xml version="1.0" encoding="UTF-8"?>
<reportDefinition xmlns="https://adwords.google.com/api/adwords/cm/v201509">
  <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>CSV</downloadFormat>
</reportDefinition>

PS: You might get ReportDefinitionError.INVALID_FIELD_NAME_FOR_REPORT and SelectorError.INVALID_PREDICATE_FIELD_NAME errors, because the fields "Id" and "Status" are not defined for AdGroup Performance Report. Use "AdGroupId" and "AdGroupStatus" instead.
