+## Title
+
+Amazon Seller Integration
+
+## Introduction
+
+This proposal outlines the integration of Amazon Seller as a data provider for the Catoff-Reclaim integration project. The integration aims to retrieve and process user order data from Amazon Seller, such as the number of orders sold, to be used within the Catoff platform. This will enable users to validate their sales performance and use it for various challenges and verifications on Catoff.
+
+## External APIs Needed
+
+- Amazon Seller API: https://developer-docs.amazon.com/sp-api/docs
+
+## Use Cases
+
+1. **User Verification**: Verify the sales activity of users on Amazon by checking their order history.
+2. **Loan Applications**: Support users in providing verified sales data for loan or credit applications, showcasing their business performance.
+3. **Tax Documentation**: Provide users with verified sales data for accurate and streamlined tax reporting and redemption.
+
+## Data Provider
+
+- **Name**: Amazon Seller Orders - Fix
+- **Hash Value**: 0x37a34b1c65f5d2a8e74b919a8e7743b5c2e0c98b4d8b9c2f64e3e7e9a84a9f2e
+
+## Code Snippet
+
+Below is a code snippet that demonstrates the key parts of the GitHub integration. The full implementation should follow the service file template.
+
+**`services/amazonSellerService.js`**
+
+```javascript
+const axios = require('axios')
+const { ReclaimServiceResponse } = require('../utils/reclaimServiceResponse')
+
+exports.processAmazonSellerData = async (proof, providerName) => {
+  const sellerId = JSON.parse(proof[0].claimData.context).extractedParameters
+    .sellerId
+  const lastUpdateTimeStamp = proof[0].claimData.timestampS
+
+  const orderCount = await getSellerOrders(sellerId)
+
+  return new ReclaimServiceResponse(
+    providerName,
+    lastUpdateTimeStamp,
+    sellerId,
+    orderCount,
+    proof[0]
+  )
+}
+
+const getSellerOrders = async sellerId => {
+  // Defining the start date to calculate orders
+  const startDate = '2020-01-01'

+  const url = `https://sellingpartnerapi-na.amazon.com/orders/v0/orders?MarketplaceIds=ATVPDKIKX0DER&CreatedAfter=${startDate}&CreatedBefore=${endDate}&SellerId=${sellerId}`
+  const amazonToken = process.env.RECLAIM_AMAZON_SELLER_TOKEN
+

+    },
+  })
+
+  const orders = response.data.Orders
+  console.log(
+    `Total orders for seller ${sellerId} since ${startDate}: ${orders.length}`
+  )
+  return orders.length
+}
