    Error Message 20133 - Invalid Import List Header

    Danielle Prey

      Our company uses Marketo as a customer integration with the application our company supports.  I don't know a lot about SOAP and APIs, ect, but the integration is used with these account details:

       

      • Marketo Account Number
      • Marketo Encryption Key
      • Marketo SOAP API Endpoint
      • REST API Endpoint
      • REST API Identity

       

      When a user processes the request for a test email campaign, the Error Message 20133 - Invalid Import List Header is always the ending result.

       

      Can anyone tell me what this error is and maybe how to resolve the issue? I would greatly appreciate it!
