Impersonation SOAP XML Example

Integration users need to provide the <ImpersonateAsResourceID> tag in the AutotaskIntegrations SOAP header. This examples creates a ticket note on behalf of another user account.

 <?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="" xmlns:xsi="" xmlns:xsd="">
    <AutotaskIntegrations xmlns="">
      <IntegrationCode>[substitute Tracking Identifier here]</IntegrationCode>
      <ImpersonateAsResourceID>[substitute ID of RESOURCE TO IMPERSONATE here]</ImpersonateAsResourceID>
    <create xmlns="">
        <Entity xsi:type="TicketNote" xmlns:xsi="">
          <Description>Note Description</Description>
          <Title>Note Title</Title>
