Tap a conversation to view the full message history

Conversations show the contact name, last message preview, and timestamp. Unread messages are highlighted.

Reply to a WhatsApp message

Open a WhatsApp conversation
Type your reply in the message input field
Tap Send

Replies are delivered through the WhatsApp Business API. The customer sees your response in their WhatsApp app as a message from your verified business account.

Note: WhatsApp has a 24-hour messaging window. You can send free-form replies within 24 hours of the customer's last message. After 24 hours, you must use an approved template message to re-open the conversation.

Send template messages

When the 24-hour window has closed or you need to initiate a conversation:

Open the WhatsApp conversation (or start a new one)
Tap the Templates icon in the message input area
Browse or search your approved WhatsApp templates
Select a template and fill in any required variables (such as customer name or order number)
Tap Send

Templates must be pre-approved through your WhatsApp Business account. You create and submit templates on the JustCall web dashboard.

Start a new WhatsApp conversation

From the Messages tab, tap the New Message icon
Enter the recipient's phone number
Select WhatsApp as the channel
Choose an approved template to initiate the conversation
Send the template message

The customer receives the message in their WhatsApp app. Once they reply, the 24-hour free-form messaging window opens.

Notifications for WhatsApp messages

WhatsApp message notifications follow your existing notification settings. If SMS alerts are enabled, you receive push notifications for incoming WhatsApp messages as well. Configure notification preferences in Settings > Notifications.
