Sending back the payment method nonce

How to send the payment method nonce you receive from Braintree back to Commerce Layer

Problem

Your customer has submitted credit card information to Braintree — i.e. through its Checkout UI integrated into your client. Your client has received a payment method nonce in response and you need to send it back to Commerce Layer to proceed with the payment flow.

The term payment method mentioned here when referring to the nonce is used to match Braintree internal naming convention and has nothing to do with Commerce Layer API payment method concept you'll find elsewhere in the guides.

Solution

To send the payment method nonce back to Commerce Layer you have to update the Braintree payment object. To do that, send a PATCH request to the /api/braintree_payments/:id endpoint, setting the payment_method_nonce attribute.

Example

The following request updates the Braintree payment source identified by the "vdDEAsZYzR" ID with the payment method nonce received from the client:

curl -g -X PATCH \
  http://yourdomain.commercelayer.io/api/braintree_payments/vdDEAsZYzR \
  -H 'Accept: application/vnd.api+json' \
  -H 'Authorization: Bearer your-access-token' \
  -H 'Content-Type: application/vnd.api+json' \
  -d '{
  "data": {
    "type": "braintree_payments",
    "id": "vdDEAsZYzR",
    "attributes": {
      "payment_method_nonce": "aaaaaa-bbb-ccc-ddd-eeeeee"
    }
  }
}'

On success, the API responds with a 200 OK status code, returning the updated Braintree payment object:

{
  "data": {
    "id": "vdDEAsZYzR",
    "type": "braintree_payments",
    "links": {
      "self": "https://yourdomain.commercelayer.io/api/braintree_payments/vdDEAsZYzR"
    },
    "attributes": {
      "client_token": "xxxx.yyyy.zzzz==",
      "payment_method_nonce": "aaaaaa-bbb-ccc-ddd-eeeeee",
      "payment_id": null,
      "local": false,
      "options": {},
      "payment_instrument":{...},
      "created_at": "2018-01-01T12:00:00.000Z",
      "updated_at": "2018-01-01T12:00:00.000Z",
      "reference": null,
      "reference_origin": null,
      "metadata": {}
    },
    "relationships": {
      "order": {
        "links": {...}
      }
    },
    "meta": {
      "mode": "test"
    }
  }
}
