# Sending message

To send a message to a person on LinkedIn, include the st.sendMessage action in your workflow. Supports text messages to existing connections.

To send a message to a person in LinkedIn, you need to include [st.sendMessage](/docs/action-st-send-message) action in your workflow. Here's an example:

**Workflow:**

```json
{
  "actionType": "st.sendMessage",
  "personUrl": "https://www.linkedin.com/in/person1",
  "text": "Hi! I'd love to connect and discuss some ideas."
}
```

**Completion:**

```json
{
  "actionType": "st.sendMessage",
  "success": true
}
```

> 💡 If you want to send a message in **Sales Navigator** (spend your Sales Navigator in-mail credits), use [`nv.sendMessage`](/docs/action-nv-send-message) action.

> 💡 To reply into a known conversation without resolving the person's profile URL, pass a `threadId` (as returned by [inbox](/docs/monitoring-inbox) or [conversation](/docs/working-with-conversations) polling) instead of `personUrl`. See [`st.sendMessage`](/docs/action-st-send-message).

> This page provides examples of [workflows](/docs/building-workflows) and their [completions](/docs/executing-workflows). For detailed documentation on constraints, parameters, and possible results of specific actions, always refer to the corresponding [action documentation pages](/docs/actions-overview).
