In the VTEX documentation, we included Yape as a payment method available for activation in the payment settings with the Checkout API.

The payment identifier field (payment_id), which currently accepts 11 digits (up to 99,999,999,999), will start accepting 12 digits (from 100,000,000,000 to 999,999,999,999). This change will occur in the coming weeks, so please review your integration if necessary to avoid transaction errors.

From now on, the user ID fields, which were previously of type Int32, have changed to the Int64 format. If your application uses this information through fields such as ‘user_id’, ‘payer_id’, ‘collector_id’, or any other reference to user IDs provided by Mercado Pago, your integration may generate errors if you do not make the necessary adjustments. See more details here.

We inform you that the integration with Mercado Pago is not compatible with the Store Credit feature of the Shopify platform.
