FAQs

What’s the difference between the WhatsApp Business API and the WhatsApp Business app?

The WhatsApp Business API is built for medium to large businesses handling a high volume of messages, while the WhatsApp Business app is designed for small businesses with simpler needs.

The API supports advanced features like automation, integration with customer management tools, and the ability to manage communication across multiple users and devices. In contrast, the app is limited to a single user on one device. The API also allows for template messaging (pre-approved messages) and scalable broadcast capabilities, which are restricted in the app.

If your business needs robust automation, multi-user access, or integration with existing systems, the API is the better choice. The app, however, is ideal for small businesses looking for a straightforward, user-friendly solution.

What steps should businesses take to follow WhatsApp's messaging policies when using the API?

To stay compliant with WhatsApp's messaging policies, businesses need to follow a few key steps:

Obtain user opt-in: Make sure users explicitly agree to receive messages from your business. Clearly state your business name and the purpose of the communication.
Use approved templates: When initiating conversations, only send pre-approved Message Templates. For user-initiated messages, respond within 24 hours without using a template.
Respect user preferences: Honor opt-out requests promptly and ensure users can easily unsubscribe from communications.
Follow data protection laws: Safeguard user data and comply with applicable privacy regulations.

By adhering to these guidelines, businesses can maintain compliance while building trust and delivering a seamless customer experience.
