**What Is Afterpay messaging?**

---

Afterpay Messaging informs your customers - as they browse - that pay by installments with Afterpay is available. This helps to improve your conversion rates and average order value.

The Afterpay Messaging Widget takes all the following actions:

* Automatically displays the most optimal payment option. If you have the Pay Monthly product, the widget displays monthly installment messaging for higher priced items and Pay-in-4 (installments) messaging for lower priced items

* Calculates and displays the installment amount

* Displays the Afterpay Information Modal when a customer clicks on the ⓘ (information) icon.
