Nager.AmazonCreatorsApi

A lightweight and easy-to-use .NET client for the Amazon Creators API.

Nager.AmazonCreatorsApi simplifies authentication and sending requests to the Amazon Creators API. Currently, the package supports GetItems requests to retrieve product data.

✨ Features

• Simple authentication workflow
• Strongly-typed request and response models
• Easy-to-use GetItems implementation
• Built for modern .NET applications
• Minimal dependencies

License Key Logic

The Nager.AmazonCreatorsApi uses a hybrid access model. While basic product metadata is accessible for free, any requests involving pricing, savings, or availability data require a valid License Key.

Feature Access Overview

Category	Access	Resource Scope	Example Fields
Basic Metadata	🔓 Free	AmazonFields.ItemInfo.*	Title, Features, ...
Media Assets	🔓 Free	AmazonFields.Images.*	Primary, Variants
Pricing & Offers	🔐 License	AmazonFields.Offers.*	Price, Availability, MerchantInfo

Important

The Product Advertising API (PA-API) will be deprecated on April 30, 2026.
This project has been renamed and updated to support the new Amazon Creators API.

⚠️ The old PA-API documentation is no longer maintained and contains outdated information.
Please refer to the official Creators API documentation:

Action Required: If you are still using PA-API, migrate your integration to the Creators API before the deprecation date.

Installation

The package is available on NuGet

PM> install-package Nager.AmazonCreatorsApi

🚀 Getting Started

GetItems

Retrieve detailed product data using ASINs.

var clientId = "YOUR_CLIENT_ID";
var clientSecret = "YOUR_CLIENT_SECRET";
var partnerTag = "YOUR_PARTNER_TAG";

var client = new AmazonCreatorsApiClient(new HttpClient());
if (!await client.AuthenticateAsync(AmazonEndpoint.US, clientId, clientSecret))
{
    Console.WriteLine("Cannot Authenticate");
    return;
}

var itemRequest = new ItemsRequest
{
    ItemIds = new string[] { "B09B2SBHQK", "B09B8V1LZ3" },
    PartnerTag = partnerTag,
    Resources = new string[]
    {
        AmazonFields.ParentASIN,
        AmazonFields.ItemInfo.Title,
    }
};

try
{
    var itemResponse = await client.GetItemsAsync(itemRequest);
}
catch (RequestException exception)
{
    var amazonErrorMessage = exception.ErrorResponse.Message;
}
catch (Exception exception)
{
}

Global Marketplaces

Switching the target marketplace is a one-liner. This automatically adjusts the base URL for all subsequent requests.

client.ChangeMarketplace(AmazonEndpoint.DE); // Germany
client.ChangeMarketplace(AmazonEndpoint.JP); // Japan
client.ChangeMarketplace(AmazonEndpoint.BR); // Brazil

Set LicenseKey

You can set your license key globally on the client class. This key is required if you plan to request any resources from the Offers scope.

AmazonCreatorsApiClient.LicenseKey = "YOUR_NAGER_LICENSE_KEY";
