Magento2 - How to place order using graphql?

Question

I am following this tutorial to process cart / checkout for placing orders using graphql. Magento GraphQl Tutorial. And we have installed stripe on magento(backend).

So we are facing issue while placing order.

• Customer logs in get a authentication token
• Create empty cart
• Add product to cart
• Set billing and shipping address for cart
• Set payment method to stripe_payments (without card details)
• Placing order receiving error here

How can I set payment method and debit card details to cart using graphql and place successful test order?

Answer 1

Make sure all steps ( 1 to 4 ) have been done without any issue. Please check the below steps for the mutation by which you can set the payment method and place the order.

Example: Use the setPaymentMethodOnCart mutation to set the payment method for your order. The value checkmo ("Check / Money order" payment method code) was returned in the query.

mutation {
      setPaymentMethodOnCart(input: {
          cart_id: "{ CART_ID }"
          payment_method: {
              code: "checkmo"
          }
      }) {
        cart {
          selected_payment_method {
            code
          }
        }
      }
    }

Response:

If the operation is successful, the response contains the code of the selected payment method.

{
  "data": {
    "setPaymentMethodOnCart": {
      "cart": {
        "selected_payment_method": {
          "code": "checkmo"
        }
      }
    }
  }
}

      payment_method: {
          code: "checkmo"
      }
  }) {
    order {
      order_id
    }
  }
}

Response:

If the operation is successful, the response contains the order ID.

{
  "data": {
    "setPaymentMethodAndPlaceOrder": {
      "order": {
        "order_id": "000000001"
      }
