\# Restrict purchases to registered users This setting allows only users with a Mercado Pago account to make purchases in your Checkout Pro. Once enabled, only authenticated customers will be able to access the checkout and use the available payment methods to complete the purchase. > WARNING > > By adding this option, it will not be possible to receive payments from users not registered in Mercado Pago, nor will you be able to receive payments via cash or bank transfer. To restrict payments exclusively to users with a Mercado Pago account, include the \`config.online.allowed\_user\_type\` parameter with the value \`account\_only\` when sending the request to the :TagComponent{tag="API" text="Create order" href="/developers/en/reference/online-payments/checkout-pro/create-order/post"} endpoint. \`\`\`curl curl -X POST \\ -H 'accept: application/json' \\ -H 'Content-Type: application/json' \\ -H 'Authorization: Bearer ENV\_ACCESS\_TOKEN' \\ -H 'X-Idempotency-Key: UNIQUE\_KEY' \\ 'https://api.mercadopago.com/v1/orders' \\ -d '{ "type": "online", "processing\_mode": "manual", "total\_amount": "1000.00", "external\_reference": "order\_pro\_123", "payer": { "email": "buyer@email.com" }, "items": \[ { "title": "My product", "unit\_price": "1000.00", "quantity": 1, "unit\_measure": "unit", "total\_amount": "1000.00" } \], "config": { "online": { "allowed\_user\_type": "account\_only" } } }' \`\`\`
