Sending from a Conversation

You can send WhatsApp messages to any contact directly from their conversation thread in QuantixOne. The first message in a new conversation must use an approved template. Once a contact replies, you can send free-form messages within a 24-hour window.

Opening the WhatsApp Composer​

  1. Open a contact's conversation (click Conversations in the left sidebar, then select the contact).
  2. In the message composer at the bottom, click the WhatsApp tab.

Sending the First Message (Template Required)​

Templates are required to open a conversation

WhatsApp's policy mandates that every new conversation — and any conversation where the 24-hour window has expired — must start with a Meta-approved template. Free-form messages are only available after the contact replies.

WhatsApp requires an approved template for the opening message in any new conversation. The composer shows a template selector when no conversation has been initiated yet.

  1. Click Select Template in the composer.
  2. Browse or search for an approved template.
  3. Select the template — a preview renders on screen.
  4. If the template has variables (e.g. {{1}}), fill in each value in the mapping panel.
  5. Click Send.

Sending Free-Form Messages (24-Hour Window)​

After a contact replies to your message, a 24-hour messaging window opens. During this window, you can send free-form text and media without a template.

  1. Type your message in the text input area.
  2. Use the formatting toolbar for bold, italic, or strikethrough if needed.
  3. Click Send.

The 24-hour window resets only when the contact replies

The window is counted from the contact's last reply, not from when you sent a message. If the contact goes quiet, the window will close and you'll need an approved template to reach out again.

Once the window closes, you must use a template again to re-initiate the conversation.

Sender Information​

The composer shows:

  • From — Your connected WhatsApp Business phone number and display name
  • To — The contact's phone number and name
