# Adds the number of installments for Alma payments to Charge objects

## What’s new

Adds the [count](https://docs.stripe.com/api/charges/object.md?api-version=2025-08-30.basil#charge_object-payment_method_details-alma-installments-count) of [installments](https://docs.stripe.com/api/charges/object.md?api-version=2025-08-30.basil#charge_object-payment_method_details-alma-installments) for [Alma payments](https://docs.stripe.com/payments/alma.md) to the [Charge](https://docs.stripe.com/api/charge/object.md?api-version=2025-08-27.basil) object.

## Impact

You can now track Alma payments by product type by using the new [count](https://docs.stripe.com/api/charges/object.md?api-version=2025-08-30.basil#charge_object-payment_method_details-alma-installments-count) property, which contains the number of installments selected by the customer for an Alma payment.
