When you collect cards from your payers and store them for later use, you must provide an agreement ID when you use the stored values for:

  • Recurring payments: you have an agreement with the payer that authorizes you to automatically debit their account at agreed intervals for fixed or variable amounts. For example, gym membership, phone bills, or magazine subscriptions.
  • Installment payments: you have an agreement with the payer that authorizes you to process multiple payments over an agreed period of time for a single purchase. For example, the payer purchases an item for $1000 and pays for it in four monthly installments.
  • Unscheduled: you have an agreement with the payer that authorizes you to process future payments when required. For example, the payer authorizes you to process an account top-up transaction for a transit card when the account balance drops below a certain threshold.
  • Industry Practice: you have an agreement with the payer that authorizes you to initiate additional transactions to fulfil a standard business practice related to an original payment initiated by the payer. For example, a delayed charge for use of the hotel mini bar after the payer has checked out or a no show penalty charge when the payer fails to show for a booking.
When you first establish an agreement with the payer you should also specify the type of agreement in agreement.type.
