WhatsApp’s global user base has crossed 2.7 billion users. Your business could benefit significantly by setting up AWS WhatsApp for ecommerce operations.

The numbers tell a compelling story. Customers feel 70% more connected when they can message businesses directly. They expect quick responses, with 82% wanting immediate replies when they ask questions. Each day, 175 million users connect with WhatsApp business accounts. Your business can make use of the WhatsApp API through AWS to automate interactions and create individual-specific experiences while cutting down operational costs.

This beginner’s piece provides straightforward, practical steps to create a WhatsApp messaging service with AWS End User Messaging Social. We cover everything from WhatsApp Business profile setup to AWS Connect WhatsApp integration.

The guide helps you send automated notifications, deliver customer support, and build interactive shopping experiences that transform your ecommerce business through AWS and WhatsApp’s capabilities.

How can I use WhatsApp Business for ecommerce?

Research by Spectrm shows 69% of customers are more likely to purchase from companies they can reach through WhatsApp. This makes WhatsApp a great tool that ecommerce businesses can use to boost their sales and customer connections.

You need to pick between two business solutions to add WhatsApp to your ecommerce strategy. The WhatsApp Business App comes free and works perfectly for small operations. It gives you basic features like quick replies, automated greetings, and product catalogs. The WhatsApp Business Platform (previously called the API) suits medium to large businesses that handle many conversations.

The Platform comes with three powerful APIs that change how you talk to customers:

• Cloud API hosted by Meta helps send and receive messages at scale
• On-Premises API runs on your own servers
• Business Manager API manages your Meta account and campaigns

WhatsApp opens up many practical uses for ecommerce. Your product catalog becomes a digital storefront where customers browse items right in their chats. You can send automated messages to recover abandoned carts, which helps a lot since 75.6% of carts get abandoned across sectors.

The app shines in keeping customers updated after purchase. Automated messages about order confirmation, shipping, and delivery keep customers informed through an app they check often. This builds trust and reduces worry. You can also collect payments safely through WhatsApp Pay.

The app becomes even more powerful when you connect it with AWS, especially through AWS End User Messaging Social. This setup lets you handle thousands of chats at once, use AI chatbots, and link WhatsApp data to your CRM systems.

Set Up Your WhatsApp Business and AWS Accounts

Setting up your Meta Business and AWS accounts is vital before you start WhatsApp automation. These accounts build the foundation of your ecommerce messaging system.

Create a Meta Business Account and WhatsApp Business Profile

Your Meta Business Account acts as the main container for your WhatsApp Business Account (WABA). Business Settings allows you to create a new account if you don’t have one already.

The setup process starts with selecting your business portfolio from the dropdown menu. Head to WhatsApp Accounts and click “Add WhatsApp account.” You’ll need to:

• Verify your phone number
• Name your account
• Specify if the account belongs to you or a client
• Pick your timezone and currency
• Set a display name that aligns with Meta’s guidelines

Meta reviews all new accounts. You can still access WhatsApp Manager during this period, but full features unlock after approval.

Set up your AWS account and install AWS CLI

AWS configuration begins with account creation. The next step involves installing AWS Command Line Interface (CLI).

Download the right package based on your system:

• Windows users should get the MSI installer from https://awscli.amazonaws.com/AWSCLIV2.msi
• macOS needs version 11 or higher
• Linux users should follow their distribution’s guidelines

Run aws --version in your terminal to verify the installation. Configure AWS CLI by typing:

aws configure

The system will ask for:

• AWS access key ID
• Secret access key
• Default region
• Output format (json, yaml, text, or table)

Your home directory stores these credentials in the .aws folder.

Understand the WhatsApp API to send messages

The WhatsApp API supports various message types. You can send text, images, documents, interactive buttons, and templates.

The “customer service window” spans 24 hours from a customer’s last message. This window lets you send any message type, but outside it, you can only use template messages.

Message sending uses endpoints like:

POST /<WHATSAPP_BUSINESS_PHONE_NUMBER_ID>/messages

Message delivery updates come through webhooks rather than API responses. Your AWS integration needs an SNS topic configured to receive these events.

Connect WhatsApp to AWS Using End User Messaging Social

Your next step after setting up both accounts is to connect WhatsApp and AWS. This connection will give your ecommerce business uninterrupted messaging capabilities. AWS End User Messaging Social (formerly part of Amazon Pinpoint) simplifies this integration.

Create an SNS topic for incoming messages

The first task is to create an Amazon Simple Notification Service (SNS) topic. This topic will work as the central hub that receives WhatsApp messages:

1. Go to the SNS console in your chosen AWS region for End User Messaging Social
2. Choose “Standard” as the topic type (FIFO topics aren’t supported)
3. Name your topic “WhatsAppIncomingMessages”
4. Save the topic’s ARN (Amazon Resource Name) after creation

This SNS topic serves as the message broker between WhatsApp and your Lambda function that processes messages.

Link your WhatsApp Business Account to AWS

The next step connects your WhatsApp Business Account (WABA) with AWS:

1. Access the End User Messaging Social section in AWS console
2. Select “Add WhatsApp phone number” button
3. Choose “Launch Facebook portal” to link AWS with your Meta business portfolio
4. Fill out the registration in the Facebook popup
5. Add the SNS topic ARN you created in the “Message and event destination” field
6. Complete the setup by clicking “Add phone number”

Check that your account status shows “Active” on the WABA page and save the “Phone number ID” for later use.

Configure message routing to AWS Lambda

The final setup involves message routing configuration:

1. AWS End User Messaging Social gets messages sent to your WhatsApp number
2. Each message creates an event published to your SNS topic
3. You need a subscription to the SNS topic to receive messages
4. AWS Lambda functions respond to these SNS notifications automatically

This setup lets you build robust ecommerce messaging workflows. Your system can now process customer questions, deliver shipping updates, and share product details through WhatsApp automatically.

Deploy and Automate WhatsApp Messaging Workflows

Now that you’ve connected your WhatsApp and AWS accounts, let’s build the functional components that will power your ecommerce messaging workflow. This significant step will help you create an automated system that naturally handles customer interactions.

Deploy the Lambda function using AWS SAM

AWS Serverless Application Model (SAM) makes it easier to deploy Lambda functions that process WhatsApp messages. Here’s how to implement it:

1. Clone the example repository:git clone https://github.com/aws-samples/aws-end-user-messaging-social-automation.git cd aws-end-user-messaging-social-automation/
2. Build the project:sam build
3. Deploy with guided prompts:sam deploy --guided

The deployment will ask you to provide:

• Stack name (e.g., “EndUserMessagingWhatsApp”)
• AWS region (matching your WABA account)
• SNS topic ARN (created earlier)
• Phone number ID (from your Meta Developer account)

You can accept the defaults for all other questions to finish the deployment.

Automate WhatsApp replies using Lambda triggers

Your Lambda function will respond to incoming WhatsApp messages automatically after deployment. Here’s how it works:

1. A customer sends a WhatsApp message to your business number
2. The message gets published to your SNS topic
3. The Lambda function starts and processes the message
4. Based on your business logic, the function sends back an appropriate response

The Lambda function handles WhatsApp’s verification requests by checking if the verify token matches the one in its environment variables. It then returns the expected HubChallenge code to establish the connection.

Use WhatsApp API to send message from website or app

You can also send messages proactively through the AWS CLI:

aws socialmessaging send-whatsapp-message \
 --cli-binary-format raw-in-base64-out \
 --message '{"messaging_product": "whatsapp", "to": "+15554567890", "text": { "preview_url": false, "body": "Hello! How can we help you?"}}' \
 --origination-phone-number-id phone-number-id-beac123456789abcdefgh \
 --meta-api-version v20.0

WhatsApp has specific rules for sending messages. You can send plain text messages only during the 24-hour “customer service window” after a customer reaches out. Marketing messages or notifications like OTPs need pre-approved templates outside this window.

Your website can use this functionality through its backend, which can call AWS Lambda whenever customer actions need WhatsApp communication.

Test, Monitor, and Optimize Your Setup

Testing AWS WhatsApp integration plays a significant role before your ecommerce messaging system goes live. A full picture will give your customers an uninterrupted experience.

Test WhatsApp message flow from user to AWS

Your testing process becomes simple after deploying the infrastructure. Add your WhatsApp business test number to your phone’s contacts. Send a simple “Hello” message to start the workflow.

The successful test indicators should show:

1. A blue check mark confirming message delivery and reading
2. A 👋 reaction appearing on your original message
3. A customized reply: “Hello {your profile name}, how can I help you?”
4. A selection list with options

This exchange shows the complete message flow: from your input through AWS processing back to WhatsApp. The technical sequence moves through this path: user sends a message → AWS End User Messaging Social routes to SNS → Lambda function processes it → response returns through the same channel.

Monitor message logs using CloudWatch

CloudWatch logs offer evidence-based information to help with troubleshooting and performance analysis. Here’s how to access these logs:

1. Go to the CloudWatch logs page
2. Search for “WhatsAppMessageHandler“
3. Select the appropriate log group
4. Click on the log stream matching your test time

Lambda’s default logging leaves out sensitive data like sender phone numbers and profile names. Check your organization’s data handling policies before you enable additional logging.

Set up cost alerts and usage metrics

AWS End User Messaging Social automatically sends cost-related metrics to CloudWatch. Create the required IAM service-linked role first:

aws iam create-service-linked-role --aws-service-name social-messaging.amazonaws.com

This creates the “AWSServiceRoleForSocialMessaging” role and enables access to two key metrics:

• WhatsAppMessageFeeCount: Tracks WhatsApp message fees
• WhatsAppConversationFeeCount: Monitors conversation fees

You can avoid surprise charges by setting up CloudWatch alarms:

1. Enable billing alerts in AWS Billing priorities
2. Create an alarm through CloudWatch console (US East region)
3. Choose “Billing” and “Total Estimated Charge” metric
4. Set your desired threshold (e.g., USD 2.00)

These metrics stay available for 15 months. This helps you analyze historical usage patterns and cost trends.

Conclusion

AWS WhatsApp integration gives your ecommerce business a great chance to revolutionize customer engagement. The steps above will help you build a powerful messaging system that handles thousands of conversations simultaneously with minimal manual work. This setup simplifies communication and creates individual-specific experiences that today’s customers expect.

The combination of WhatsApp’s worldwide reach and AWS’s reliable system gives your business enterprise-level features that were once limited to big corporations.
