1. WhatsApp Business API:
   • WhatsApp offers a Business API that allows businesses to send messages to their customers in a more structured and compliant manner.
   • Businesses need to apply and be approved by WhatsApp to use the API. The API enables messaging automation, template messaging (for predefined messages like transaction notifications), and integration with CRM systems.
2. Compliance and Guidelines:
   • WhatsApp has strict guidelines to prevent spam and ensure user privacy. Messages sent through the WhatsApp Business API must adhere to these guidelines.
   • Messages should be opt-in, meaning users must consent to receive messages from businesses.
3. Third-Party Providers:
   • Some third-party providers offer services to manage bulk WhatsApp messaging campaigns. These providers typically facilitate compliance with WhatsApp’s policies and provide tools for managing contacts, scheduling messages, and analyzing campaign performance.
   • Examples of third-party providers include Twilio, MessageBird, and Infobip, which offer WhatsApp API integration for businesses.
4. Types of Messages:
   • Template Messages: Pre-approved message templates can be used for specific types of notifications or customer interactions.
   • Session Messages: Messages sent within a 24-hour window after a user’s last interaction with the business are considered session messages and do not require templates.
5. Legal and Ethical Considerations:
   • Businesses should comply with local regulations regarding electronic messaging and data protection laws (e.g., GDPR in Europe).
   • Ensuring users have consented to receive messages and providing opt-out mechanisms are crucial for compliance and maintaining trust.
