Amazon Product Advertising API Client for Node
npm install apac
apac (Amazon Product Advertising Client) will allow you to access the Amazon Product Advertising API from Node.js.
Learn more about the Amazon Product Advertising API.
node-apac is just a thin wrapper around Amazon's API. The only intent is to take care of request signatures, performing
the HTTP requests, processing the responses and parsing the XML. You should be able to run any operation because the
operation and all parameters are passed directly to the execute method just as they will be passed to Amazon. The result
is that you feel like you're working directly with the API, but you don't have to worry about some of the more tedious
tasks.
Install using npm:
``bash`
$ npm install apac
Here's a quick example:
`javascript
const {OperationHelper} = require('apac');
const opHelper = new OperationHelper({
awsId: '[YOUR AWS ID HERE]',
awsSecret: '[YOUR AWS SECRET HERE]',
assocId: '[YOUR ASSOCIATE TAG HERE]'
});
opHelper.execute('ItemSearch', {
'SearchIndex': 'Books',
'Keywords': 'harry potter',
'ResponseGroup': 'ItemAttributes,Offers'
}).then((response) => {
console.log("Results object: ", response.result);
console.log("Raw response body: ", response.responseBody);
}).catch((err) => {
console.error("Something went wrong! ", err);
});
`
Example Response:
`javascript`
{
ItemSearchResponse: {
OperationRequest: [Object],
Items: [Object]
}
}
Since we just wrap the Amazon Product Advertising API, you'll reference their API docs:
API Reference
Sign up here: https://affiliate-program.amazon.com/gp/advertising/api/detail/main.html
This will also direct you where to get your security credentials (accessKeyId and secretAccessKey)
You will also need to go here: http://docs.aws.amazon.com/AWSECommerceService/latest/DG/becomingAssociate.html
and click on one of the locale specific associate websites to sign up as an associate and get an associate ID,
which is required for all API calls.
By default, Amazon limits you to one request per second per IP. This limit increases with revenue performance. Learn
more here: http://docs.aws.amazon.com/AWSECommerceService/latest/DG/TroubleshootingApplications.html
To help you ensure you don't exceed the request limit, we provide an automatic throttling feature. By default, apac will
not throttle. To enable throttling, set the maxRequestsPerSecond param when constructing your OperationHelper.
`javascript`
var opHelper = new OperationHelper({
awsId: '[YOUR AWS ID HERE]',
awsSecret: '[YOUR AWS SECRET HERE]',
assocId: '[YOUR ASSOCIATE TAG HERE]',
maxRequestsPerSecond: 1
});
To use a locale other than the default (US), set the locale parameter.
`javascript`
var opHelper = new OperationHelper({
awsId: '[YOUR AWS ID HERE]',
awsSecret: '[YOUR AWS SECRET HERE]',
assocId: '[YOUR ASSOCIATE TAG HERE]',
locale: 'IT'
});
