Quick Start

Install

To use this module directly install it as a dependency:

npm install amazonpay

Testing in Sandbox Mode

Instantiating the client: The sandbox parameter is defaulted to false if not specified:

Your Amazon Pay keys are

available in your Seller Central account

const Client = require('amazonPayClient').amazonPayClient;

const configArgs = {
    'merchantId' : 'MERCHANT1234567',
    'accessKey' : 'ABCDEFGHI1JKLMN2O7',
    'secretKey' : 'abc123Def456gHi789jKLmpQ987rstu6vWxyz/ds', 
    'clientId' : 'amzn1.application-oa2-client.45789c45a8f34927830be1d9e029f480',
    'region' : 'us',
    'currencyCode' : 'USD',
    'sandbox' : true,

    /**
     * Below is a variable that can be passed that will convert 
     *  the XML response to a JSON string or object instead. 
     *  It is not part of the API values. If you specify this value in 
     *  reqParam, this will overide configArgs value
     * jsonResponse can be 'jsonString' for a JSON string
     *  or it can be 'jsonObject' for a JSON object
     * @optional 'jsonResponse' - [String]
     **/
    'jsonResponse' : 'jsonString'
};

const client = new Client(configArgs);

Making an API Call

Below is an example on how to make the SetOrderAtributes API call:

const reqParam = {
    'amazonOrderReferenceId': amazonOrderReferenceId,
    'amount': amount,
    'orderItemCategory': orderItemCategories,
    'storeName': storeName,
    'sellerOrderId': sellerOrderId,
    'sellerNote': sellerNote,
    'customInformation': customInformation

     **/
    'accessToken' : 'Atza|IwEBICpkg...', 
    'amazonOrderReferenceId': 'S01-8022464-2595273' 
};

const response = newClient.getOrderReferenceDetails(reqParam);

Below is an example on how to make the Authorize API call:

/** For idempotency the AuthorizationReferenceId must be unique.
 *   To accomplish this we can generate a 32 character unique identifier
 *   using uuid/v4 https://www.npmjs.com/package/uuid and remove 
 *   the dashes.
 **/

const uuidv4 = require('uuid/v4');

const reqParam = { 
    'amazonOrderReferenceId' : 'S01-8022464-2595273',
    'authorizationReferenceId' : uuidv4().toString().replace(/-/g, ''),
    'amount' : '10',
    'sellerNote' : 'Test note',
    'transactionTimeout' : '0',
    'captureNow' : 'false'

 *   To accomplish this we can generate a 32 character unique identifier
 *   using uuid/v4 https://www.npmjs.com/package/uuid and remove 
 *   the dashes.
 **/

const uuidv4 = require('uuid/v4');

const reqParam = {
    'amazonCaptureId': amazonCaptureId,
    'refundReferenceId': uuidv4().toString().replace(/-/g, ''),
    'amount': amount,
    'sellerNote': 'Test note',
};

const response = newClient.refund(reqParam);

Below is an example on how to make the GetRefundDetails API call:

const reqParam = {
    'amazonRefundId': amazonRefundId
};

const response = newClient.getRefundDetails(reqParam);

Below is an example on how to make the CreateOrderReferenceForId API call:

const reqParam = {
    'id': amazonBillingAgreementId,
    'amount': billingAmount,
    'idType': 'BillingAgreement',
    'storeName': storeName,
    'sellerOrderId': sellerOrderId,
    'sellerNote': sellerNote,
    'customInformation': customInformation
};

const response = newClient.createOrderReferenceForId(reqParam);

Below is an example on how to make the GetMerchantAccountStatus API call:

const response = newClient.getMerchantAccountStatus(reqParam);

Below is an example on how to make the SetBillingAgreementDetails API call:

const reqParam = {
    'amazonBillingAgreementId': amazonBillingAgreementId,
    'storeName': storeName,
    'sellerOrderId': sellerOrderId,
    'sellerNote': sellerNote,
    'customInformation': customInformation
};

const response = newClient.setBillingAgreementDetails(reqParam);

Below is an example on how to make the GetBillingAgreementDetails API call:

const reqParam = {
    /** If you call this before ConfirmBillingAgreement, 
     *   to get all the buyer address information you 
     *   must pass 'accessToken'.
     *   After Confirm, 'accessToken' is not used.
     **/
    //'accessToken' : accessToken, 
    'amazonBillingAgreementId': amazonBillingAgreementId,
};

const response = newClient.getBillingAgreementDetails(reqParam);

Below is an example on how to make the ValidateBillingAgreement API call:

reqParam = {
    'amazonBillingAgreementId': amazonBillingAgreementId,
};

const response = newClient.validateBillingAgreement(reqParam);

Below is an example on how to make the CloseBillingAgreement API call:

reqParam = {
    'amazonBillingAgreementId': amazonBillingAgreementId,
};

const response = newClient.closeBillingAgreement(reqParam);

Below is an example on how to make the AuthorizeOnBillingAgreement API call:

/** For idempotency the AuthorizationReferenceId must be unique.
 *   To accomplish this we can generate a 32 character unique identifier
 *   using uuid/v4 https://www.npmjs.com/package/uuid and remove 
 *   the dashes.
 **/

const uuidv4 = require('uuid/v4');

reqParam = {
    'amazonBillingAgreementId': amazonBillingAgreementId,
    'authorizationReferenceId': uuidv4().toString().replace(/-/g, ''),
    'amount': billingAmount,
    'transactionTimeout': transactionTimeout,
    'orderItemCategory': orderItemCategories,
    'captureNow': captureNow,
    'storeName': storeName,
    'sellerOrderId': sellerOrderId,
    'sellerNote': sellerNote,
    'customInformation': customInformation
};

const response = newClient.authorizeOnBillingAgreement(reqParam);

Below is an example on how to make the GetUserInfo API call:

const accessToken = 'Atza|IwEBIAplM...';

const response = newClient.getUserInfo(accessToken);

Parsing the Response for getUserInfo only

The response will return a Promise containing a JSON object

response.then(function (result) {
    console.log('User Info:');
    console.log(result);
    console.log('');
}).catch(err => {
    console.log(err);
}); 

Parsing the Response for API calls except for GetUserInfo

The response will return a Promise containing a XML string

// no additional processing
response.then(function (result) {
    responseData = result;
    console.log(responseData);
    parseString(responseData, function (err, parseResult) {
        parsedXML = parseResult;
        const initialParse = JSON.parse(JSON.stringify(parsedXML));
        if (initialParse.CreateOrderReferenceForIdResponse) {
            jsonOutput = initialParse.CreateOrderReferenceForIdResponse.CreateOrderReferenceForIdResult[0];
            const amazonCaptureIdRegion = (OrderReferenceDetails[0].AmazonOrderReferenceId[0]).toString();
            console.log('CreateOrderReferenceForID response data:');
            console.log(responseData);
            console.log(`AmazonOrderReferenceId: ${amazonamazonOrderReferenceIdRegion}`);
        }
    });
}).catch(err => {
        console.log(`Capture error data ${regionVal}:`);
        console.log(err.body);
});

If you set jsonResponse = 'jsonString' in the config or reqParam

The response will return a Promise containing a JSON string

// Retrieve the AmazonOrderReferenceId from CreateOrderReferenceForId API response
response.then(function (result) {
    responseData = result;
    jsonOutput = JSON.parse(responseData).CreateOrderReferenceForIdResult;
    const amazonOrderReferenceIdRegion = (jsonOutput.OrderReferenceDetails.AmazonOrderReferenceId).toString();
    console.log('CreateOrderReferenceForID response data:');
    console.log(responseData);
    console.log(`AmazonOrderReferenceId: ${amazonamazonOrderReferenceIdRegion}`);
}).catch(err => {
    console.log(err.body);
});
