Send Typing Indicator RCS | Pinnacle

Send a typing indicator from an RCS agent to a recipient.

This endpoint allows RCS agents to display a typing indicator to recipients. The indicator is a message bubble with animated typing dots like this:

Use Case: Typing indicators are especially useful for providing feedback to users while the agent is thinking or generating a response that may take some time, creating a more engaging conversational experience.

Expiration: Typing indicators automatically expire after around 20 seconds or when the agent sends a message, whichever comes first.

Frequency: You can send typing indicators as many times as needed, though only one will be displayed at a time. Sending multiple typing indicators will extend the duration of the current indicator.

Note: Typing indicators are best-effort hints, not delivery-guaranteed state. The platform is allowed to coalesce or drop them, and the client UI decides when to show/hide.
