What is WhatsApp Business API?
WhatsApp Business API is a powerful solution designed for medium and large businesses to manage customer communication at scale. Unlike the regular WhatsApp Business app, it does not have a user interface and works through software integrations like CRM, chatbots, and automation tools. It enables businesses to send notifications, automate replies, and handle multiple customer queries efficiently. This API is ideal for companies that need bulk messaging, team access, and advanced automation to improve customer engagement, support, and overall communication experience.

The phone number tier of your WhatsApp API account will determine your messaging limit – the number of Contacts an account can message. There are five tiers a phone number inside a WABA can reach, including:
● Unverified Trial Tier: Send messages to 50 unique Contacts in a rolling 24-hour period & have up to 2 numbers
● Tier 1: Send messages to 1K unique Contacts in a rolling 24-hour period & have up to 25 numbers

● Tier 3: Send messages to 100K unique Contacts in a rolling 24-hour period

To maintain the quality of customer experience, WhatsApp requires businesses to obtain opt-ins from customers prior to starting a chat with Message Templates.
Opt-ins can be obtained both on and off WhatsApp. Think interactive voice response (IVR), website forms, WhatsApp Ads, WhatsApp links, WhatsApp QR codes or through WhatsApp threads (customer-initiated messages).
All Unicode languages—including RTL scripts (Arabic, Hebrew), Indic scripts (Hindi, Tamil), and CJK languages.
You pay per message template approval and per incremental message. Volume discounts kick in at 10,000+ messages/month.

WhatsApp does not allow businesses using WhatsApp API to send messages without approval. To prevent spam and ensure businesses reply to incoming messages quickly, WhatsApp imposes a messaging limitation called Session Messaging
Session Messaging allows you to reply to incoming messages within a 24-hour window. Once the 24-hour window closes, you can no longer send Session Messages. There is no need for any prior approval before sending a Session Message, provided that it abides by WhatsApp Business Policy and WhatsApp Commerce Policy.
After 24 hours from last incoming message, businesses are only allowed to reply with Message Templates. Message Templates are pre-approved messages used to reopen the 24-hour Messaging Window or start a new conversation. Policy and WhatsApp Commerce Policy.
A phone number lives under a WABA, which is managed through Facebook Business Manager. Facebook Business Manager is also where you manage other Facebook assets. Each WABA can have up to 25 numbers, depending on the phone number tier. Each Chat ON Desk account supports integration with a single phone number.
