Commerce API with JWT Encryption - QA ONLY


This document describes the steps needed to integrate with Walmart Checkout API(V2). Please note that this is a work in progress and is subject to change.

 

Checkout API Workflow

  1. Partner will create an account on developer.walmartlabs.com and let Walmart API team know about their username for Mashery account.

  2. Partner will provide order details in an JSON format that conforms to the JSON Schema document that Walmart provided to partner.

  3. Partner will use Checkout Feed (http://api.walmartlabs.com/v1/feeds/checkoutV2?apiKey=<apikey>) daily to get all items available for checkout.

  4. Products available for checkout to partner will exclude any Walmart.com Marketplace items, service plans, bundles and tires. Certain heavy items included in the catalog that are categorized as freight items will not be available for delivery to Alaska, Hawaii, and U.S. Protectorates like Puerto Rico and U.S. Virgin Islands. Walmart will use commercially reasonable efforts to identify such excluded items in the Checkout Feed API.

  5. Until the development of separate APIs for cancellations and returns, they will be completed through a manual process

  6. Daily and monthly reports will be shared via FTP with partner containing details of orders placed, orders shipped and cancellations. Month-end report will also contain details of commissions payable for the month. You need to provide us your FTP server location and credentials so that we can put the files on your server. 

 

Dev Portal

You need to create an account on http://developer.walmartlabs.com and send us an email at affilops@wal-mart.com  with your Mashery username. Walmart will then create a Checkout API package account for you. 

 

Authentication

Before you can make actual Checkout calls, you will to get an OAuth token. This token is valid for 10 mins and you will have to get a new token after that. Here is a sample way to get your OAuth token:

curl -i -u '<Your API key>:<your API shared secret>' -d 'grant_type=client_credentials' https://api.walmartlabs.com/v2/qa/oauth2/token

A typical response will look like:

HTTP/1.1 200 OK
Cache-Control: no-store

Content-Type: application/json;charset=UTF-8

Date: Tue, 18 Jun 2013 08:17:54 GMT

Server: Mashery Proxy

X-Mashery-Responder: prod-j-worker-us-west-1c-13.mashery.com

Content-Length: 116

Connection: keep-alive


{"token_type":"bearer","mapi":"z8snfepkm763xvg85ngt9jq6","access_token":"dr9r4uue4a4mewejyyhm5x8q","expires_in":600}

 

The access_token field in above response contains the OAuth token.

 

Headers

Every API call should have the following headers.

 

Header        Value
X-Walmart-User-IP Customer IPv4 address (Eg. 161.170.244.20)
X-Walmart-User-Device-Type        Customer Device Type. One of browser, mobile_web, batch, 

iphone_app, ipad_app, android_app, mobile_other
X-Walmart-User-Agent Customer User Agent (Eg. Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36) 

 

 

 

API Flow

Checkout occurs in 2 steps. The first step is the Prepare Order call which gives pricing/tax/shipping details of items sent in the request and returns back an id. The subsequent Place order call executes the order.

 

Prepare Order

There are 3 top level json objects: customerInfo, items and shippingInfo

Request:

 

curl -H "Authorization: Bearer dr9r4uue4a4mewejyyhm5x8q" -H "X-Walmart-User-IP: 127.0.0.1" -H "X-Walmart-User-Device-Type: browser" -H "X-Walmart-User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36" -d @prepare.json https://api.walmartlabs.com/v2/qa/order/prepare

            "modified": true,
            "valid" : true 
        }
    }
}

 

Address Validation


The "shippingInfo" field in the prepare request optionally takes an parameter "addressValidationMode" which is used to control the behaviour of address validation failure. The "address" field in response in turn has two fields, "modified" which indicates if the address was modified by Walmart and "valid" which indicates if address is valid. The behaviour of these two fields is summarized below,

 

STRICT LENIENT
Valid Address

valid : true

modified: false

valid : true

modified: false
Valid Address with small correction (eg. zip) 

valid : true

modified : true

valid : true

modifed : true
Invalid Address

Error response with status code 40019

valid : false

 

Passing an "Invalid Address" in STRICT mode returns an error response with status code 40019 whereas in LENIENT mode "valid" is set to false with a successful 200 response. Though our address validation service makes the best effort to validate an address, there are cases where valid addresses are called out as invalid. The consumer should treat our valid flag as a warning that the address could be probably wrong and allow for the customer to either make corrections or submit the address as is if the customer confirms.

 

Use the token received above in the Place Order call.

}

 

Response:

{
  "orderId": "5091400341459"
} 

 

CVV:

API does NOT expect CVV. 

CVV should NOT be passed in the payload as plain text. 

Work is in progress to to enhance API to accept encrypted CVV. Until otherwise communicated, CVV should not be part of payload.

 

Credit Card:

Card number to use for testing : 4012000077777777

Item id to use for testing : 173053133, 915607725, 256177555, 460509746, 578022998, 705958404, 21693006

Note: some items can return out of stock


The "cardNumber" field in the above request is encrypted with JWT format string of the actual card number.

The exchange of credit card number is done using JWE (JSON Web Encryption). This is standard format for encrypting json based structures over web, as defined in RFC https://tools.ietf.org/html/rfc7516.  There are a number of libraries opensource and propietary available implementing this standard, in all programming languages so it is easier to create a JWE encrypted JSON and decrypting. 

We will be using JWE compact serialization for encrypting information.

Refer JWT: https://en.wikipedia.org/wiki/JSON_Web_Token

JWT Introduction: https://jwt.io/introduction/

Creating a JWE can be referred here https://connect2id.com/products/nimbus-jose-jwt/examples/jwt-with-rsa-encryption

A public documentation how JWE is created can be refered here https://medium.facilelogin.com/jwt-jws-and-jwe-for-not-so-dummies-b63310d201a3

JWT Libraries: https://jwt.io/

 

QA:  Use the sample java code below which contains public key cert (X509 Certificate) used for encrypting credit card number. 

Production:  Please contact affilops@wal-mart.com for the public key cert (X509 Certificate) that you need to use for the encryption in production.

Developing with the QA environment

Once you begin development, you should first try out against our QA environment. This way you'd be able to iron out all issues and place successful mock orders without getting your credit card charged. The list of items and the corresponding seller ids which work in the QA environment is available here. Note that not all items in this list are guaranteed to work all the time and the list is subject to change.

You should use the following endpoints:

https://api.walmartlabs.com/v2/qa/order/place
