How does WhatsApp Business API work ?

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 :

• Verified Meta Business Portfolio:

‍ Business Phone Number and mail ID: You need a dedicated phone number and email ID for WhatsApp Business API. The contact number can be new number or an existing WhatsApp number that is migrated to the API platform. The number and email ID will be the point of contact for all customer communication. ‍

Business Website: A business website with updated Privacy Policy and Terms & Conditions is mandatory to support business verification and compliance with Meta's requirements. ‍

Verified Facebook/Meta Business Account: required to manage business assets, users, permissions and WhatsApp Business Accounts. If not verified, BSPs like GreenAds Global can help with the verification.

• 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.
