# getCartDetailsById

Use this global method to verify whether the cart contains a subscription product. If the cart contains a subscription product, do not allow customer credit as the payment method since subscription renewals require a primary payment method. If your store sells subscriptions, use this method to verify whether the cart contains subscription products before allowing the user to select the customer credit as a payment method.

## Sending a request

This method accepts parameters in JSON string format. You need to pass the `cartId` to this method.
