GraphQL API

The Headless Magento architecture, coupled with GraphQL, enables us to deliver a more responsive and personalized user interface. This enhancement provides the agility to adapt and incorporate future payment innovations seamlessly

Below are the steps to be followed:

1. Generate customer Token for authentication
URL : {{magento_base_url}}/graphql

Request

mutation {
 generateCustomerToken(email: "emailid", password: "password") {
 token
 }
}

Response

{
 "data": {
 "generateCustomerToken": {
  "token": "1qenuvub2pk7yft7t4zd131ekyia6wu3"
  }
 }
}

Note : Use this token for authentication.

2. Retrieve the Magento cart ID

URL : {{magento_base_url}}/graphql

Request

{
 customerCart{
  id
 }
}

Response

{
 "data": {
 "customerCart": {
  "id": "RpFl1pemya4oBw1w0l23JvBk8TsToeye"
  }
 }
}

Note : Use this card_id for payment session creation and place order

3. Create mastercard payment session using Magento
Create the payment session only after billing and shipping address are added.
URL : {{magento_base_url}}/graphql

card_id : It is getting from step 2
method_code : tns_hpf or tns_hosted

Request

mutation {
 createNewPaymentSession(input: { cart_id:"card_id", 
 payment_method: { code: "method_code" } }) {
  id
  version
 }
}

Response

{
 "data": {"createNewPaymentSession": {
  "id": "SESSION0002129083069L01811395H8",
  "version": "0b687ae901"
  }
 }
}

4. Add card details to session using Mastercard API endpoint
URL : {{host}}/api/rest/version/{{version}}/merchant/{{merchantId}}/session/{{session}}

Request

{
"sourceOfFunds": {
 "type": "CARD",
 "provided": {
  "card": {
   "number": "512345XXXXXXXXX8",
   "expiry": {
    "month": "01",

    },
   "securityCode": "100"
   }
  }
 }
}

mutation {
 setPaymentMethodAndPlaceOrder(
 input: { cart_id: "card_id", payment_method: { code:
