\# One-time payments with saved cards One-time payments with saved cards (Card on File) are payments that use the registered payment method data to make occasional charges without requiring the user to re-enter the card information. These are payments that do not have a recurrence, but rather depend on an action by the merchant or the customer to be executed, such as automatic toll charges or payments in delivery apps with saved cards, respectively. To process one-time payments with saved cards, send a \*\*POST\*\* to the endpoint :TagComponent{tag="API" text="/v1/orders" href="/developers/en/reference/online-payments/checkout-api/create-order/post"}. You must send your :toolTipComponent\[Access Token\]{content="Private key of the application created in Mercado Pago, used in the \_backend\_. You can access it through \*Your integrations > Application details\*."} and the information detailed below for this type of payment. \`\`\`curl curl -X POST \\ 'https://api.mercadopago.com/v1/orders' \\ -H 'Content-Type: application/json' \\ -H 'X-Idempotency-Key: {{SOME\_UNIQUE\_VALUE}}' \\ -H 'Authorization: Bearer {{YOUR\_ACCESS\_TOKEN}}' \\ -d '{ "type": "online", "external\_reference": "ext\_ref\_1234", "total\_amount": "1000.00", "processing\_mode": "automatic\_async", "payer": { "customer\_id": "1234567890" }, "transactions": { "payments": \[ { "amount": "1000.00", "automatic\_payments": { "payment\_profile\_id": "035979dc46c645c4ae12554835b07943", "retries": 3 }, "stored\_credential": { "payment\_initiator": "merchant", "reason": "card\_on\_file", "previous\_transaction\_reference": "REF-987-654-321", "first\_payment": false } } \] } }' \`\`\` | Attribute | Type | Description | Required | | :--- | :--- | :--- | :--- | | \`Authorization\` | \_Header\_ | Refers to your private key, the :toolTipComponent\[Access Token\]{content="Private key of the application created in Mercado Pago, used in the \_backend\_.
