4) How does WhatsApp Business API work ?

5) Getting Started with GreenAds Global : Requirements

To successfully set up and operate WhatsApp Business API, businesses need to meet Meta’s technical and operational requirements such as :

• Meta Business Portfolio (Meta Business Manager account): A Meta Business Portfolio is your business's central account on Meta. It is used to create and manage your WhatsApp Business Account (WABA), phone numbers, users and permissions.

• WhatsApp Business Account (WABA): A WABA is the account within your Meta Business Portfolio that owns your WhatsApp Business phone number(s) and enables them to be used with the WhatsApp Business API.

• Proof of Legal Business Status: Meta requires official documents, to verify that your business is legally registered (any one document from each category) :  

Business Name Verification: Certificate of Incorporation, GST Registration Certificate, Udyam/MSME Certificate, PAN Card, Shop & Establishment Certificate, or Business License (for international businesses).  

Business Address & Phone Verification: Utility bill (electricity, water, gas, or broadband) or a bank statement with the business address and phone number.

• Dedicated Business Phone Number and mail ID: It can be a new number or an eligible existing number migrated to the WhatsApp Business API. The number and email ID will be the point of contact for all customer communication.

• Business Website: An active website with updated Privacy Policy and Terms & Conditions, mandatory to support business verification and compliance with Meta's requirements.

‍

Once these you have these requirements, there are 2 ways that you can access the WhatsApp Business API :

a) Meta’s WhatsApp Cloud API

The WhatsApp Business Cloud API is hosted and maintained by Meta, so businesses don't need to manage servers, software updates or security.

To get started, you need to create a Meta Business Portfolio, register your application (eg: your business website), connect your WhatsApp Business Account (WABA) and business phone number.  

This gives you your API credentials that allow your website to communicate with WhatsApp.

While Meta manages the infrastructure, businesses are still responsible for integrating the API, configuring real-time messaging updates and building features such as chatbots or shared inboxes—making the setup complex for businesses without a development team.

b) WhatsApp API through a Business Solution Provider (BSP)

A WhatsApp API solution provider, such as GreenAds Global, still uses Meta's Cloud API, but handles most of the setup and provides additional business tools.

Typical onboarding looks like this:

• Sign Up with a BSP: Create an account with an official WhatsApp Business Solution Provider (BSP), such as GreenAds Global.

• Connect Your Meta Business Portfolio/ Business manager account, WABA and Phone Number: Connect your Meta Business Portfolio (Business Manager account), then link your WhatsApp Business Account (WABA) and register your business phone number with the WhatsApp Business API.

• Complete Business Verification: If your business hasn't been verified by Meta, we can guide you through the verification process.

• API Configuration: GreenAds configures the WhatsApp Cloud API, API credentials and webhooks required for messaging.

• Start Using Business Tools: Once setup is complete, you can use GreenAds Telinfy platform to manage conversations, send campaigns, build chatbots, integrate with your CRM, view analytics and collaborate through a shared team inbox.

With GreenAds Global, the technical setup and ongoing maintenance are handled by us, allowing you to focus on communicating with customers faster and growing your business.

6) Operational Concepts of the WhatsApp Business API

After setup, the WhatsApp Business API operates according to Meta's messaging policies, pricing model and quality standards. Understanding these concepts is essential for using the API effectively and scaling customer communication.

• Messaging Categories and Templates: There are two message categories- Marketing and Utility. Creating message templates for each and obtaining Meta approval before sending them is mandatory.

• Pricing for messages: Meta charges businesses per delivered template message, with rates varying by recipient country and message category.  Since WhatsApp API access alone doesn't include a dashboard or user interface, official providers like GreenAds add platform fees to provide the tools, support and infrastructure needed to actually use the API.

• Customer opt-in: Customers must opt-in to receive WhatsApp messages. Among others, opt-ins can be collected through websites, checkout pages, SMS or email.

• Quality rating: Your quality rating is based on the recent messages that your customers have received over the past seven days. This rating is determined by feedback from your customers.

• Messaging limits: Meta analyses your message quality to the customer base. Based on this analysis, your business portfolio’s eligibility for automatic scaling will either be approved or denied.

• Security and Compliance: Ensure customer data is protected and follow privacy rules, including GDPR (General Data Protection Regulation) and Meta’s Business and Commerce Policies.

• Developer or BSP based API Integration: Choosing between a direct Cloud API integration or official providers depends on your business's technical bandwidth. It is much easier to integrate WhatsApp with business applications, automate messaging and manage a large customer base with an official provider like GreenAds Global.

7) Key features and capabilities of the WhatsApp Business API

WhatsApp Business API provides businesses with powerful tools to communicate with customers at scale. It includes features such as:  

• Supports rich media: Businesses can share rich media such as images, videos or audio files, location pins, and product catalogues, directly within WhatsApp thanks to the WhatsApp Business API. This eliminates the need for customers to visit external website, thus effectively engaging customers on a platform that customers use everyday.

• Bulk messaging at scale: Unlike the free WhatsApp Business app, the WhatsApp Business API is built for volume. It allows you to send thousands of messages instantly to your target audience

• ‍No-Code AI Chatbot: Build and deploy automated WhatsApp chatbots using a visual drag-and-drop builder of predefined customer conversations —no coding required. Automated customer service via WhatsApp bots is expected to save greater than 2.6 billion hours globally by 2025, reducing agent workload and improving customer  service.

• AI Chatbot or BYOA (Bring Your Own AI): Use the GreenAds Telinfy AI chatbot or connect your own AI chabot to automate intelligent, context-aware customer conversations. ‍

• Customer relationship management (CRM) integrations: You can connect WhatsApp directly to your existing business tools, like customer database or email systems, so that all data is in sync. This enables businesses to connect customer conversations with orders, payments and customer records delivering a much faster and personalized customer service.

• Analytics and reporting: While WhatsApp Business API can be used to send any type engaging content, it can also be used to track message delivery rates, read rates and customer engagement. This can help you optimize the communication strategies.

• Shared team inbox: Unlike the WhatsApp Business App, which limits access to a single device, the API allows multiple agents to manage customer conversations simultaneously from one shared WhatsApp number. This eliminates delays and missed conversations, ensuring every customer query is handled promptly.

• Role-Based Access Control: Assign user roles and permissions to control who can access, manage and respond to customer conversations. ‍
