paapi5-typescript-sdk

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:

``shell
npm i -S paapi5-typescript-sdk
`

Or

`shell
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_

`typescript
import * as SDK from 'paapi5-typescript-sdk';
`

And use what you need later

`typescript
const request = new SDK.SearchItemsRequest(/ ... /);
`

You can refer to the Amazon Product Advertising API 5.0 for further details about every request

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:

`typescript
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'

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

`typescript
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

Amazon documentation here

Example

`typescript
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

Amazon documentation here

Example

`typescript
import { GetItemsRequest, PartnerType, Host, Region } from 'paapi5-typescript-sdk'

const request = new GetItemsRequest(
{ / parameters / }
'partnerTag',
PartnerType.ASSOCIATES,
'accessKey',
'secretKey',
Host.Italy,
Region.Italy
);

const data = await request.send();
`

#### GetVariationsRequest

Amazon documentation here

Example

`typescript
import { GetVariationsRequest, PartnerType, Host, Region } from 'paapi5-typescript-sdk'

const request = new GetVariationsRequest(
{ / parameters / }
'partnerTag',
PartnerType.ASSOCIATES,
'accessKey',
'secretKey',
Host.Italy,
Region.Italy
);

const data = await request.send();
`

#### SearchItemsRequest

Amazon documentation here

Example

`typescript
import { SearchItemsRequest, PartnerType, Host, Region } from 'paapi5-typescript-sdk'

const request = new SearchItemsRequest(
{ / parameters / }
'partnerTag',
PartnerType.ASSOCIATES,
'accessKey',
'secretKey',
Host.Italy,
Region.Italy
);

const data = await request.send();
