AutoBill.addCampaign to add a Campaign Code to an existing AutoBill.
Add a Campaign Code to an existing AutoBill:
First, create the AutoBill:
AutoBill.update, or AutoBill.addCampaign. (AutoBill.addCampaign works similarly to AutoBill.update when adding a Campaign Code to an existing AutoBill.)
AutoBill.update, and will return an error code of 400, with a text string explanation. The error may be that no Product or Billing Plan on the AutoBill is eligible for the Promotion, or that the Coupon Code has already been used against its defined number of AutoBills, or that the Promotion Code is out of date.Applying a Campaign Code to a Specific Product on an AutoBill
