Unofficial TypeScript SDK for Product Advertising API 5.0
Installation
In order to install this SDK, you just have to run you well-known npm
or yarn
scripts:
npm i -S paapi5-typescript-sdk
Or
yarn add paapi5-typescript-sdk
And there you go! Enjoy 😎
API
Everything is exported from the SDK: requests' classes, models, utility types, helper and so on..
If you want to import everything
import * as SDK from 'paapi5-typescript-sdk';
And use what you need later
const request = new SDK.SearchItemsRequest(/* ... */);
You can refer to the Amazon Product Advertising API 5.0 for further details about every request
Auth
In order to validate all the requests against the APIs, I've implemented almost from scratch the AWS V4 signing process, creating the SignHelper
class.
This is intended for interal use, but if you want to use it for other purposes, here you can find an example:
import { HttpMethod, SignHelper, Region } from 'paapi5-typescript-sdk'
const timestamp = 1609426121130;
const path = '/paapi5/getbrowsenodes';
const method = HttpMethod.POST;
const service = 'ProductAdvertisingAPI';
const accessKey = 'accessKey';
const secretKey = 'secretKey';
const signHelper = new SignHelper(accessKey, secretKey);
const headers = {
host: 'webservices.amazon.it',
'x-amz-target': 'com.amazon.paapi5.v1.ProductAdvertisingAPIv1.GetBrowseNodes',
'x-amz-date': signHelper.toAmzDate(timestamp),
'content-encoding': 'amz-1.0',
'content-type': 'application/json; charset=utf-8',
};
const header = signHelper.getAuthorizationHeader(path, method, {}, headers, Region.ITALY, service, timestamp);
// 'AWS4-HMAC-SHA256 Credential=accessKey/20201231/eu-west-1/ProductAdvertisingAPI/aws4_request, SignedHeaders=content-encoding;content-type;host;x-amz-date;x-amz-target, Signature=ba741bfb87f9bf3b9b343d72e4f76dc9f169f2e86a047423d783a2169f03c595'

Requests
Here you can find all the classes you need in order to communicate with the APIs
CommonRequest
This is intended to be just a parent class to be extended by all the other specific classes.
Its only purposes are:
- Instantiate a
SignHelper
for internal use - Prepare all the request's parameters including the URL, the headers and the payload
- Abstracts away the
send()
method so that all the sub-classes don't need to implement it
Example
import { CommonRequest, PartnerType, Host, Region } from 'paapi5-typescript-sdk'
const commonRequest = new CommonRequest(
'partnerTag',
PartnerType.ASSOCIATES,
'accessKey',
'secretKey',
Host.Italy,
Region.Italy
);
// Not an real request, just an example
const data = await commonRequest.send();
GetBrowseNodesRequest

Example
import { GetBrowseNodesRequest, PartnerType, Host, Region } from 'paapi5-typescript-sdk'
const request = new GetBrowseNodesRequest(
{ /* parameters */ }
'partnerTag',
PartnerType.ASSOCIATES,
'accessKey',
'secretKey',
Host.Italy,
Region.Italy
);
const data = await request.send();
GetItemsRequest

'secretKey',
Host.Italy,
Region.Italy
);
const data = await request.send();
GetVariationsRequest

'secretKey',
Host.Italy,
Region.Italy
);
const data = await request.send();
