Whether you’re an established e-commerce business or exploring ways to compete with Amazon’s marketplace dominance, this comprehensive guide reveals everything you need to master this game-changing service for sellers.

From understanding the merchant requirements to implementing advanced sales strategies, you’ll discover how to leverage Buy with Prime to increase conversions, reduce cart abandonment, and earn customer trust while keeping shoppers on your branded experience.

What is Amazon Buy with Prime?

Buy with Prime is Amazon’s merchant service that allows e-commerce businesses to offer Prime benefits directly on their websites to Amazon Prime members.

Core Functionality:

  • Integrates Amazon’s fulfillment network with your website
  • Provides Prime delivery speeds (1-2 day delivery) for eligible products
  • Uses Amazon’s payment processing and checkout system
  • Maintains your brand experience while leveraging Amazon’s logistics

How It Works:

  • Products are stored in Amazon fulfillment centers (FBA)
  • Prime members can check out using their Amazon credentials
  • Amazon’s logistics network fulfils orders
  • Customers receive the same delivery and return experience as Amazon.com
  • You retain the direct customer relationship

Business Model: Amazon Buy with Prime extends its logistics capabilities beyond its marketplace, allowing third-party retailers to compete on delivery speed and checkout convenience while maintaining their independent e-commerce presence.

Understanding Amazon’s Multi-Channel Fulfillment (MCF)

Before diving into Buy with Prime implementation, it’s crucial to understand Amazon’s Multi-Channel Fulfillment (MCF) service, which forms the backbone of Buy with Prime operations.

What is MCF?

Multi-Channel Fulfillment is Amazon’s service that allows sellers to fulfill orders from any sales channel (your website, other marketplaces, social media) using Amazon’s fulfillment network. Your inventory stored in Amazon warehouses can be used to fulfill orders from anywhere, not just Amazon.com.

Key MCF Features for Buy with Prime:

  • Unified Inventory Management: Your FBA inventory automatically becomes available for MCF orders, eliminating the need for separate stock allocations.
  • Flexible Shipping Options: Choose from standard, expedited, or priority shipping speeds tailored to your customer’s needs and pricing strategy.
  • Branded Packaging Options: Amazon offers plain packaging or your custom branded packaging (additional fees apply) to maintain your brand experience.
  • Order Tracking Integration: Customers receive tracking information that can be customized to reflect your brand while using Amazon’s delivery network.
  • Return Management: Returns are processed through Amazon’s network, but you maintain control over return policies and customer communication.

  • Request access through the official Buy with Prime API portal
  • Complete business verification process
  • Receive API credentials after approval

Step 3: Integrate Login with Amazon or Amazon Pay 

To identify the shopper and verify that they are a Prime member, you can use Login with Amazon (LWA) or Amazon Pay

JavaScript

// Login with Amazon Integration

// Source: https://documents.buywithprime.amazon.com/bwp-api/docs/use-login-with-amazon-for-shopper-identity

// Initialize LWA

window.onAmazonLoginReady = function() {

    amazon.Login.setClientId(‘YOUR_LWA_CLIENT_ID’);

};

// Handle LWA authorization

function loginWithAmazon() {

    amazon.Login.authorize({

        scope: ‘profile’

    }, function(response) {

        if (response.error) {

            console.error(‘LWA Authorization failed:’, response.error);

            return;

        }

        // Store the access token for Buy with Prime API calls

        const lwaAccessToken = response.access_token;

        localStorage.setItem(‘lwa_token’, lwaAccessToken);

    });

}

Step 4: Generate API Credentials and Access Token 

Before you call the Buy with Prime API, you must generate your Buy with Prime API credentials and use the API credentials to get an access token

javascript

// Get Buy with Prime Access Token

// Source: https://documents.buywithprime.amazon.com/bwp-api/docs/authenticate-to-the-buy-with-prime-api

async function getBuyWithPrimeAccessToken() {

    const tokenUrl = ‘https://api.buywithprime.amazon.com/token’;

    const response = await fetch(tokenUrl, {

        method: ‘POST’,

        headers: {

            ‘Content-Type’: ‘application/x-www-form-urlencoded’,

        },

        body: new URLSearchParams({

            ‘grant_type’: ‘client_credentials’,

            ‘client_id’: ‘YOUR_CLIENT_ID’,

            ‘client_secret’: ‘YOUR_CLIENT_SECRET’,

            ‘scope’: ‘buy-with-prime:write buy-with-prime:read’

        })

    });

    const tokenData = await response.json();

    return tokenData.access_token;

}

Step 5: Configure Product Inventory 

Before you can offer Buy with Prime, you must populate the Buy with Prime catalog with products. You can add products to your Buy with Prime catalog in the following two ways: You can upload a CSV file that contains your product information, which supports up to 15000 products per upload

javascript

// Create Product in Catalog

// Source: https://documents.buywithprime.amazon.com/bwp-api/docs/create-and-manage-products-in-a-catalog

async function createProduct(accessToken, targetId, productData) {

    const url = ‘https://api.buywithprime.amazon.com/graphql’;

    const mutation = `

        mutation CreateProduct($input: CreateProductInput!) {

            createProduct(input: $input) {

                id

                externalId

                title

                status

            }

        }

    `;

    const variables = {

        input: {

            externalId: productData.sku,

            title: productData.title,

            description: productData.description,

            brand: productData.brand,

            price: {

                amount: productData.price,

                currencyCode: “USD”

            },

            images: productData.images.map(img => ({

                url: img.url,

                altText: img.altText

            }))

        }

    };

    const response = await fetch(url, {

        method: ‘POST’,

        headers: {

            ‘Content-Type’: ‘application/json’,

            ‘Authorization’: `Bearer ${accessToken}`,

            ‘x-api-target-id’: targetId,

            ‘x-api-version’: ‘2024-11-01’

        },

        body: JSON.stringify({

            query: mutation,

            variables: variables

        })

    });

    return await response.json();

}

Step 6: Create Delivery Previews 

The following is an example of a complete request to the delivery Preview query

JavaScript

// Get Delivery Preview

// Source: https://documents.buywithprime.amazon.com/bwp-api/docs/create-delivery-previews

async function getDeliveryPreview(accessToken, targetId, productId, lwaToken = null) {

    const url = ‘https://api.buywithprime.amazon.com/graphql’;

    const query = `

        query DeliveryPreview($input: DeliveryPreviewInput!) {

            deliveryPreview(input: $input) {

                id

                deliveryGroups {

                    id

                    deliveryOffers {

                        policy {

                            messaging {

                                messageText

                                locale

                                badge

                            }

                        }

                    }

                }

            }

        }

    `;

    const variables = {

        input: {

            products: [{

                productIdentifier: {

                    externalId: productId

                },

                amount: {

                    unit: “UNIT”,

                    value: 1

                }

            }],

            // Include shopper identity if available for a more accurate preview

            (lwaToken && {

                terms: {

                    shopperIdentity: {

                        lwaAccessToken: {

                            externalId: “session_” + Date.now(),

                            value: lwaToken

                        }

                    }

                }

            })

        }

    };

    const response = await fetch(url, {

        method: ‘POST’,

        headers: {

            ‘Content-Type’: ‘application/json’,

            ‘Authorization’: `Bearer ${accessToken}`,

            ‘x-api-target-id’: targetId,

            ‘x-api-version’: ‘2024-11-01’

        },

        body: JSON.stringify({

            query,

            variables

        })

    });

    return await response.json();

}

Step 7: Create Buy with Prime Orders 

To create an order, you call the function to “create Order” with a “Create Order” Input object

JavaScript

// Create Buy with Prime Order

// Source: https://documents.buywithprime.amazon.com/bwp-api/docs/create-a-buy-with-prime-order

async function createOrder(accessToken, targetId, orderData) {

    const url = ‘https://api.buywithprime.amazon.com/graphql’;

    const mutation = `

        mutation CreateOrder($input: CreateOrderInput!) {

            createOrder(input: $input) {

                id

                externalId

                status

                total {

                    amount

                    currencyCode

                }

            }

        }

    `;

    const variables = {

        input: {

            externalId: orderData.orderId,

            products: orderData.items.map(item => ({

                productIdentifier: {

                    externalId: item.sku

                },

                amount: {

                    unit: “UNIT”,

                    value: item.quantity

                }

            })),

            terms: {

                shopperIdentity: {

                    lwaAccessToken: {

                        externalId: orderData.sessionId,

                        value: orderData.lwaAccessToken

                    }

                }

            }

        }

    };

    const response = await fetch(url, {

        method: ‘POST’,

        headers: {

            ‘Content-Type’: ‘application/json’,

            ‘Authorization’: `Bearer ${accessToken}`,

            ‘x-api-target-id’: targetId,

            ‘x-api-version’: ‘2024-11-01’

        },

        body: JSON.stringify({

            query: mutation,

            variables

        })

    });

    return await response.json();

}

Step 8: Subscribe to Buy with Prime Events

Buy with Prime publishes events when the state of underlying resources changes. To subscribe to events, see Steps to Subscribe to Buy with Prime events

JavaScript

// Event Processing Webhook Endpoint

// Source: https://documents.buywithprime.amazon.com/bwp-api/docs/steps-to-subscribe-to-buy-with-prime-events

const express = require(‘express’);

const crypto = require(‘crypto’);

app.post(‘/webhooks/buy-with-prime-events’, express.raw({type: ‘application/json’}), (req, res) => {

    const signature = req.headers[‘x-amz-sns-signature’];

    const body = req.body.toString();

    // Verify webhook signature (implementation depends on your setup)

    if (!verifyAmazonSignature(signature, body)) {

        return res.status(400).send(‘Invalid signature’);

    }

    const event = JSON.parse(body);

    // Handle different event types

    switch (event.Type) {

        case ‘Notification’:

            const message = JSON.parse(event.Message);

            handleBuyWithPrimeEvent(message);

            break;

        case ‘SubscriptionConfirmation’:

            // Confirm subscription by visiting the SubscribeURL

            confirmSubscription(event.SubscribeURL);

            break;

    }

    res.status(200).send(‘OK’);

});

function handleBuyWithPrimeEvent(eventData) {

    switch (eventData.eventType) {

        case ‘OrderStatusChange’:

            updateOrderStatus(eventData.orderId, eventData.newStatus);

            break;

        case ‘InventoryChange’:

            updateLocalInventory(eventData.productId, eventData.newQuantity);

            break;

        case ‘RefundProcessed’:

            processRefund(eventData.orderId, eventData.refundAmount);

            break;

    }

}

Advanced Configuration Options

Error Handling Implementation

GraphQL Error Management

Per the GraphQL specification, the Buy with Prime API always returns a 200 status OK for all responses, even if those responses contain errors. 

If the errors array is present in the response, iterate through the errors array to evaluate the errors

JavaScript

// Error Handling for Buy with Prime API

// Source: https://documents.buywithprime.amazon.com/bwp-api/docs/call-the-buy-with-prime-api

function handleBuyWithPrimeResponse(response) {

    const { data, errors } = response;

    if (errors && errors.length > 0) {

        errors.forEach(error => {

            const { extensions } = error;

            if (extensions && extensions.classification) {

                const { type, code } = extensions.classification;

                switch (type) {

                    case ‘ThrottlingError’:

                        const retryAfter = extensions.retryAfter || 5000;

                        setTimeout(() => {

                            // Retry the request

                        }, retryAfter);

                        break;

                    case ‘ValidationError’:

                        console.error(`Validation error: ${code}`, error.message);

                        // Handle validation errors

                        break;

                    case ‘InternalServerError’:

                        if (extensions.retryAfter) {

                            setTimeout(() => {

                                // Retry once

                            }, extensions.retryAfter * 1000);

                        }

                        break;

                    case ‘ResourceNotFoundError’:

                        console.error(‘Resource not found:’, error.message);

                        break;

                }

            }

        });

    }

    return data;

}

Real-time Inventory Sync

javascript

// Inventory Management Configuration

// Based on the Buy with Prime event system

const inventoryManager = {

    async syncInventoryWithBuyWithPrime(accessToken, targetId) {

        const url = ‘https://api.buywithprime.amazon.com/graphql’;

        const query = `

            query GetInventory($input: ProductsInput!) {

                products(input: $input) {

                    id

                    externalId

                    inventory {

                        quantity

                        status

                    }

                }

            }

        `;

        const variables = {

            input: {

                // Add your product filters here

            }

        };

        const response = await fetch(url, {

            method: ‘POST’,

            headers: {

                ‘Content-Type’: ‘application/json’,

                ‘Authorization’: `Bearer ${accessToken}`,

                ‘x-api-target-id’: targetId,

                ‘x-api-version’: ‘2024-11-01’

            },

            body: JSON.stringify({

                query,

                variables

            })

        });

        const result = await response.json();

        return handleBuyWithPrimeResponse(result);

    }

};

Companies selling specialized software, educational materials, and professional equipment serve urgent business needs. 

B2B buyers increasingly expect B2C-level convenience, and you can capture emergency orders and end-of-quarter purchases with Amazon’s reliable delivery infrastructure.

Top 6 Advanced Strategies to Maximize Your Buy with Prime Success

1. Strategic Product Selection for Maximum Impact

Start Small, Think Big

Don’t rush to make every product of  Amazon Buy with Prime eligible right away. This is one of the biggest mistakes sellers make. Instead, pick your winners first.

Here’s what to do: Choose products that make you the most money per sale. These high-margin items can handle Amazon’s fees and still leave you with good profits. Also, focus on your best-selling products – the ones customers already love and buy frequently.

Think about which products really benefit from fast delivery. Emergency items, last-minute gifts, or business supplies work great. Items like decorative artwork or furniture might not need two-day delivery as much.

Start with 5-10 products, learn how the system works, then expand based on what performs well.

Why this works: You make more money while learning the ropes. The data from your best products helps you decide what to add next.

2. Pricing Intelligence and Margin Optimization

Price for the Premium Service You’re Providing

Amazon’s fulfillment isn’t free, but it’s not just a cost – it’s a premium service that customers value. Many shoppers will pay extra for guaranteed fast delivery and Amazon’s trusted service.

Here’s what to do: Calculate all your costs first – Amazon’s fees, storage, and service charges. Then look at what competitors charge for fast shipping. You’ll often find customers are willing to pay more for the convenience and reliability.

Test different prices. Start higher than you think and see how it affects sales. The Amazon Prime badge creates trust that can justify premium pricing. Monitor your conversion rates to find the sweet spot between profit and sales volume.

Why this works: Customers often connect higher prices with better quality and service. The Prime badge gives them confidence in their purchase.

3. Inventory Forecasting and Demand Planning

Use Amazon’s Data Superpowers

Amazon has massive amounts of data that can help you predict what customers want and when they want it. This helps you avoid the nightmare of running out of stock.

Here’s what to do: Use Amazon’s tools to see buying patterns and seasonal trends. Set up automatic reordering so you never run out of your most important products. Being out of stock kills your conversion rates and frustrates customers.

Pay attention to Amazon’s inventory reports. They show you optimal stock levels and help you plan for busy seasons or sales events. The data is much more detailed than what you can get from your website alone.

Why this works: Empty shelves equal lost sales and disappointed customers. Amazon’s data helps you stay stocked with the right products at the right times.

4. Customer Journey Optimization

Make Prime Benefits Impossible to Miss

Your website needs to showcase Amazon Buy with Prime benefits clearly. Don’t hide this valuable feature – make it the star of your product pages.

Here’s what to do: Put Prime badges where customers can see them easily – on product pages, search results, and during checkout. 

Create special sections for Prime-eligible products. Use countdown timers showing delivery deadlines like “Order by 2 PM for delivery tomorrow.”

Show trust signals like Amazon’s customer service guarantee and easy returns. Create urgency with messages about limited-time fast delivery availability. 

Test different badge placements and messages to see what works best.

Why this works: The Prime badge reduces purchase anxiety. Customers trust Amazon’s delivery promises, which helps them buy with confidence.

5. Multi-Channel Revenue Stream Development

Get Amazon’s Power Without Amazon’s Control

Buy with Prime lets you use Amazon’s amazing fulfillment system while keeping control of your business. You’re not dependent on their marketplace rules and fees.

Here’s what to do: Get your own website as your main sales channel while Amazon handles shipping. Keep control over your prices, branding, and customer relationships. You can also sell on other platforms while using Amazon for fulfillment.

Collect customer emails and create your database. Create exclusive offers only available on your website. Use Amazon’s reliable shipping to support growth across all your sales channels.

Why this works: You get the best of both worlds – operational excellence without giving up control of your business or customer relationships.

6. Customer Data and Remarketing Integration

Keep the Customer Relationship Yours

Amazon ships your products, but the customers are still yours. Use this relationship to drive future sales and earn loyalty.

Here’s what to do: Collect customer information during checkout on your website. Create email campaigns based on what people bought and when they bought it. Set up retargeting ads created using an ad maker tools on social media and Google using purchase data.

Calculate how much each customer is worth over time. Create loyalty programs and special offers like prime shopping for your best customers. Use purchase timing to predict when people need to reorder consumable products.

Why this works: You combine Amazon’s excellent service with your own marketing skills. This creates a powerful advantage that drives both immediate sales and long-term customer value.

Troubleshooting – 5 Common Seller Issues and Business Solutions

Issue 1: Low Buy with Prime Adoption Rates

Solution: Audit your product mix and pricing. Ensure your Buy with Prime products offer clear value over marketplace alternatives. 

Consider promotional pricing during initial rollout to drive adoption.

Issue 2: Inventory Management Conflicts

Solution: Implement separate inventory planning for FBA and your other sales channels. 

Use Amazon’s inventory management tools to prevent conflicts and ensure adequate stock levels for Prime delivery promises.

Issue 3: Customer Service Confusion

Solution: Create clear customer service protocols, distinguishing between pre-sale inquiries (your responsibility) and post-sale/shipping issues (Amazon’s responsibility). Train your team on the handoff process.

Issue 4: Profitability Concerns with FBA Fees

Solution: Conduct a thorough cost analysis, including increased conversion rates and reduced operational costs. 

Factor in the customer lifetime value increase from improved experience when calculating ROI.

Issue 5: Technical Integration Challenges

Solution: Work with Amazon-certified developers or use approved e-commerce platforms with built-in Buy with Prime support. Invest in proper integration to avoid customer experience issues that hurt conversions.
