# Offer deferred interest

> Let customers finance eligible orders with a deferred-interest benefit

## Overview

Deferred interest lets a customer finance an eligible purchase over a fixed term with no interest, provided the financed balance is paid off within that term. Customers are offered a choice between their standard rewards and a deferred-interest financing benefit on qualifying orders.

Because eligibility is assessed at the **order** level rather than the **transaction** level, integrating deferred interest requires you to share order data with Imprint. This guide walks through the end-to-end flow.

<Info>
  Deferred interest is only available for programs whose rewards accrual type is `STATEMENT` or `DELAYED`. Programs that issue rewards with `INSTANT` accrual do **not** support deferred interest. See [Benefit selection windows](#benefit-selection-windows) below.
</Info>

## Integration flow

<Steps>
  <Step title="Order creation — Partner">
    When a customer places an order, create a corresponding order in Imprint with a **`POST`** to [**`/v2/orders`**](https://docs.imprint.co/api-reference/orders/create-orders). Imprint responds with an `order_id`, which you should store to reference the order later.
  </Step>

  <Step title="Order events — Partner">
    Map the order to its card transaction(s) with a **`POST`** to [**`/v2/order_events`**](https://docs.imprint.co/api-reference/order-events/create-order-events), associating one or more `network_transaction_id` values with the `order_id`. Imprint uses this mapping to determine eligibility for the order.
  </Step>

  <Step title="Benefit selection — Customer">
    The customer chooses between rewards and financing within the eligibility window inside Imprint's servicing experience. They are notified of an eligible order via SMS, which links them to the selection flow. See [Benefit selection](#benefit-selection) below.
  </Step>

  <Step title="Order modification — Partner">
    If the order changes (for example, an item is removed or refunded), keep Imprint in sync with a **`PUT`** to [**`/v2/orders/{order_id}`**](https://docs.imprint.co/api-reference/orders/modify-order). Order amount changes can affect eligibility.
  </Step>
</Steps>

## Order eligibility & terms

Eligibility is determined by Imprint's ledger based on the **order amount** and **term criteria**. Eligibility is performed at the *order* level, not the *transaction* level — this is the core reason orders are required for deferred-interest eligibility.

The eligibility criteria are configured as a table of duration, minimum order amount, and maximum order amount. An order qualifies for a given term when its amount falls within that term's amount range. For example:

| Template | Duration  | Min order amount | Max order amount |
| -------- | --------- | ---------------- | ---------------- |
| `6mo`    | 6 months  | \$500.00         | \$999.99         |
| `12mo`   | 12 months | \$1,000.00       | \$1,999.99       |
| `24mo`   | 24 months | \$2,000.00       | (no upper bound) |

<Note>
  The values above are illustrative. The exact duration tiers and amount ranges are configured per program — your Imprint team will provide the table that applies to your program.
</Note>

If a customer selects financing but does not pay off the balance within the term, the order **breaches**. APR for breached deferred-interest orders is assessed at the cardholder's base APR.

## Benefit selection

After placing an eligible order, a customer is opted into their default benefit, `REWARDS`. They then have a configurable number of days to select their benefit — either `REWARDS` or `FINANCING` — within Imprint's servicing experience, generally by following a link sent over SMS that informs them of their eligibility.

### Benefit selection windows

The configurable selection window is constrained by the program's rewards accrual type:

| Accrual type | Behavior                                                      | Selection window                                                                                                   |
| ------------ | ------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------ |
| `STATEMENT`  | Rewards are batched and issued on statement dates.            | Up to 5 days.                                                                                                      |
| `DELAYED`    | Rewards are issued after a configurable delay (in days).      | Must be shorter than the reward-issuance delay. E.g. if rewards accrue after 5 days, the window is at most 4 days. |
| `INSTANT`    | Rewards are issued immediately when the transaction confirms. | Not supported — deferred interest is unavailable.                                                                  |

<Warning>
  The benefit-selection window must close before rewards are issued. With `INSTANT` accrual, rewards are issued before a customer could ever make a selection, so deferred interest cannot be offered.
</Warning>
