Messaging
Overview of messages — individual communications within a chat thread.
Messages are individual communications within a chat thread.
Messages can include text, media attachments, rich link previews, special effects (like confetti or fireworks), and reactions. All messages are associated with a specific chat and sent from a phone number you own.
Messages support delivery status tracking, read receipts, and editing capabilities.
Rich Link Previews
Send a URL as a link part to deliver it with a rich preview card showing the
page’s title, description, and image (when available). A link part must be the
only part in the message — it cannot be combined with text or media parts.
To send a URL without a preview card, include it in a text part instead.
Limitations:
- A
linkpart cannot be combined with other parts in the same message. - Maximum URL length: 2,048 characters.
