API Reference/Endpoints

Send a message in a chat

POST/api/linkedin/gateway/chats/{chat_id}/messages

Sends a message into an existing chat. This is the raw messaging call the higher-level Send a connection request or message endpoint uses under the hood, exposed directly for when you already have a chat to reply into.

Authentication

Send your personal API key as a bearer token. A missing, malformed or revoked key returns 401.
