Quick answer. A suggested action is a tappable button that triggers a device action: open a URL, dial a number, view a location on a map, share the user’s location, or add an event to their calendar. Like replies, each action has display text and postbackData, plus an action-specific block. Actions turn a message into a one-tap task — “Track,” “Call,” “Directions,” “Add to calendar” — which is where RCS replaces error-prone typed input.
Common action types:
{ "action": { "text": "Visit site", "postbackData": "visit",
"openUrlAction": { "url": "https://example.com" } } }
{ "action": { "text": "Call us", "postbackData": "call",
"dialAction": { "phoneNumber": "+18005551234" } } }
{ "action": { "text": "Add to calendar", "postbackData": "cal",
"createCalendarEventAction": {
"startTime": "2026-06-12T15:00:00Z",
"endTime": "2026-06-12T15:30:00Z",
"title": "Service appointment" } } }
