Why are we getting a Zuora internal error: The request failed with HTTP status 404: Not Found?


When trying to calculate sales tax in Zuora an error is received explaining that "The request failed with HTTP status 404: Not Found".




  • This is most likely caused by the bill run exceeding the number of lines or documents allowed per bill run, cannot exceed:
    • 1,000 items per single transaction
    • 10,000 transactions (documents)
    • 40,000 or more lines
    • If your bill run exceeds these numbers, you must split them into smaller bill runs or invoices (exceeds item limit)
  • When you review your bill run, if it does not exceed any of the above requirements, please contact Support.
