When a connection request is sent, a connection.sent webhook event will be triggered. When the connection is accepted, a connection.accepted webhook event will be triggered.
Connection notes are only supported for LinkedIn Premium accounts. For free accounts, the connection request will be sent without a note.
LinkedIn has daily limits on connection requests. Check the sender’s remaining capacity using the List Senders endpoint.
