In the Canopy system of record, a line item represents a transaction that occurs on a customer’s account. These line items can be created via API call (eg. POST payment, charge) or could be created via an automated action (eg. applying a late fee to an account, issuer processor voiding a transaction). See additional information regarding line item status here. Line items can broadly be categorized into four groups:

Interest

These are different types of interest that can accrue in a customer’s account.

Name	Description
AM_DI	Aggregated deferred interest accrued on embedded loan line items, calculated at the end of the promotional period.
AM_INTEREST	Interest accrued on an embedded loan line items.
CHARGE_REVERSAL_INTEREST	A line item, related to a CHARGE_REVERSAL, that decreases the account interest balance by the amount of the interest assessed on the reversed CHARGE line item.
CREDIT_OFFSET_INTEREST	An arbitrary line item created to increase the interest balance of the account.
CREDIT_OFFSET_DEFERRED_INTEREST	An arbitrary line item created to increase the deferred interest balance of the account.
DEFERRED_INTEREST	Deferred interest accrued on account from within the promotional period.
INTEREST	Accrued interest which increases the balance of an account.
PAYMENT_REVERSAL_INTEREST	Generated if the account accrues additional interest due to a payment reversal. This is due to a higher principal balance for interest generation based on the payment's reversal.
PAYMENT_REVERSAL_DEFERRED_INTEREST	Generated if the account accrues additional deferred interest during a deferred interest promotion due to a payment reversal. This is due to a higher principal balance for interest generation based on the payment's reversal.

Payments

Payments are transactions that decreases the balance owed on an account.

CHARGE_REVERSAL_PRINCIPAL	A line item, related to a CHARGE_REVERSAL, that decreases the account principal by the principal amount of the reversed CHARGE line item.
DEBIT_OFFSET	An arbitrary line item created to decrease the principal, interest, or fee balance of the account. The allocation column of this line item determines whether this offset is applied to principal, interest, or fees.
DI_WAIVER	Deferred interest waiver. An amount of interest, which will be reversed if a loan is paid off before promotion expiration.
REFUND	An arbitrary line item that decreases the account balance: this is distinct from a CHARGE_REVERSAL, which will also reverse fees and interest on the account as a result of the reversed CHARGE.
PAYMENT	Payment created via API call
PAYMENT_SPLIT	Line item representing portion of payment applied to reducing a particular fee, interest, or principal line item. See Payment Split.
