Customer Support: Managing 2-Way Conversations via WhatsApp API
Broadcasts are great, but customer service requires a 2-way conversation. Learn how to set up an interactive helpdesk via WhatsApp Business API.

While WhatsApp Business API is famous for sending massive OTPs and notifications, its true power lies in 2-way conversations. Customers expect to reply to your messages and get immediate help.
What is 2-Way Chat on WhatsApp API?
Unlike SMS Masking which is strictly 1-way (recipients cannot reply), WhatsApp API supports full conversational flows. When a customer replies to your broadcast or sends the first message to your number, a 'Customer Service Window' opens for 24 hours.
The 24-Hour Rule
Meta enforces a strict 24-hour customer service window to prevent spam. If a customer messages you, you have 24 hours to reply with free-form text. Once the 24 hours pass, you can only message them again using a pre-approved Template Message.
To handle 2-way chat at scale, you connect your WABA number to an Inbox Dashboard or an Omnichannel platform. This allows multiple agents to reply to customers simultaneously from the same official WhatsApp number.
