Installation

$3

The Product Advertising API NodeJS SDK can be installed via npm:

``shell
npm install paapi5-nodejs-sdk-codeit --save
`

You should now be able to require('paapi5-nodejs-sdk') in javascript files.

The library also works in the browser environment via npm and browserify. After following
the above steps with Node.js and installing browserify with npm install -g browserify,
perform the following (assuming main.js is your entry file, that's to say your javascript file where you actually
use this library):

`shell
browserify main.js > bundle.js
`

Then include bundle.js in the HTML pages.

Using Webpack you may encounter the following error: "Module not found: Error:
Cannot resolve module", most certainly you should disable AMD loader. Add/merge
the following section to your webpack config:

`javascript
module: {
rules: [
{
parser: {
amd: false
}
}
]
}
`

Please follow the installation instruction and execute the following JS code:

Simple example for SearchItems to discover Amazon products with the keyword 'Harry Potter' in All categories:

`javascript
var ProductAdvertisingAPIv1 = require('paapi5-nodejs-sdk');

var defaultClient = ProductAdvertisingAPIv1.ApiClient.instance;

// Specify your credentials here. These are used to create and sign the request.
defaultClient.accessKey = '';
defaultClient.secretKey = '';

/**
* Specify Host and Region to which you want to send the request to.
* For more details refer:
* https://webservices.amazon.com/paapi5/documentation/common-request-parameters.html#host-and-region
*/
defaultClient.host = 'webservices.amazon.com';
defaultClient.region = 'us-east-1';

var api = new ProductAdvertisingAPIv1.DefaultApi();

/**
* The following is a sample request for SearchItems operation.
* For more information on Product Advertising API 5.0 Operations,
* refer: https://webservices.amazon.com/paapi5/documentation/operations.html
*/
var searchItemsRequest = new ProductAdvertisingAPIv1.SearchItemsRequest();

/* Enter your partner tag (store/tracking id) and partner type /
searchItemsRequest['PartnerTag'] = '';
searchItemsRequest['PartnerType'] = 'Associates';

// Specify search keywords
searchItemsRequest['Keywords'] = 'Harry Potter';

/**
* Specify the category in which search request is to be made.
* For more details, refer:
* https://webservices.amazon.com/paapi5/documentation/use-cases/organization-of-items-on-amazon/search-index.html
*/
searchItemsRequest['SearchIndex'] = 'All';

// Specify the number of items to be returned in search result
searchItemsRequest['ItemCount'] = 1;

/**
* Choose resources you want from SearchItemsResource enum
* For more details, refer: https://webservices.amazon.com/paapi5/documentation/search-items.html#resources-parameter
*/
searchItemsRequest['Resources'] = ['Images.Primary.Medium', 'ItemInfo.Title', 'Offers.Listings.Price'];
