Follow the steps below to configure the Mercado Pago account as the only payment method available in the checkout. ::::TabsComponent :::TabComponent{title="Configure via frontend SDK"} To restrict payments to users with a Mercado Pago account only, include the \`purpose\` parameter with the value \`wallet\_purchase\` in the payment preference configuration.
