Introduction

If you do not already have an account with Merchant Warrior, first you will need to sign up for our services.

Once your account has been set up, navigate to Barracks and select Settings from the lefthand navigation menu. Near the top of this page there's a section labelled "Direct API" under "Merchant Settings". This contains three key pieces of information you will need to utilize Merchant Warrior services.

  1. Your Merchant UUID and API Key. These are two identifiers we use to check that a request is coming from you, and are included as parameters in most API requests.
  2. Your API Passphrase. This is the final primary aspect of identity verification and must be kept hidden from the public. If you believe your passphrase may have been compromised, we recommend that you change it as soon as possible.
Requests

API requests are submitted to Merchant Warrior API services using POST, and must be performed over HTTPS. These POST requests will be directed at https://api.merchantwarrior.com/[endpoint]/, where [endpoint] is detailed in the introduction to each API section. Requests made as part of sandbox testing, https://base.merchantwarrior.com/[endpoint]/ is used instead.

If you would prefer to submit JSON requests and receive JSON responses you will need to submit two additional headers with your requests:

  • MW-API-VERSION: 2.0
  • Content-Type: application/json
Hash Generation

Verification hashes are used to prove to MW that the request(s) being sent have been generated by you, and not a malicious third party who may have discovered your merchantUUID and apiKey. Even if a malicious third party was to discover the request data you have sent, they would not be able to create requests without knowing your API Passphrase. Your API Passphrase can be modified in the MW administration interface.

Hash Generator

Responses

Responses will be received in XML or JSON formatting (depending on if the JSON headers have been sent)

<?xml version="1.0" encoding="UTF-8"?>
<mwResponse>
    <responseCode>0</responseCode>
    <responseMessage>...</responseMessage>
   ...
</mwResponse>
{
"responseCode":0,
"responseMessage":"...",
...
}

Details about the specific contents of each response can be found with the corresponding method in this documentation.

Response Codes

There are three possible types of responseCode.

If the responseCode is >= 0, the responseMessage field will either contain a preset error or, if applicable, the direct error response given by the provider or MW Vault.

responseCode Meaning
< 0 MW validation error
= 0 Transaction/Operation was successful
> 0 Transaction/Operation was declined or delayed by the provider or service

Response Messages

All MW validation errors will contain a three-digit code prefix at the beginning of the responseMessage. This code will allow you to determine what specifically caused the MWE validation error to be returned, and allow you to deal with it accordingly.

responseCode Prefix Description
-3 001 Required field missing
-2 002 Invalid amount
-2 003 Invalid currency
-2 004 Invalid email
-2 005 Invalid name

Simulator

Merchant Warrior has developed a simulation engine to enable your testing to be as comprehensive as possible. Please use these cards if you have been told that you are connected to the MW Simulator. The cards listed here will only work in the sandbox environment, and will not function in production.

These cards will all give the specified response. Any card name, expiry and CVN can be used with these cards, as long as they are valid for the card. eg. Amex cards must have a 4 digit CVN, all other cards must have 3 digits, and the expiry needs to be in the future.

Specific Authorization Code Testing

If you need to simulate a specific issuer response code that is not covered by the above scenarios, use the following cards. You can include the exact issuer response code you want to receive by including it in the Card Name field, eg "08Bob Jones" will produce an "08 - Honour with identification" response.
