Send Connection Request

Use the Send Connection Message endpoint to reach out to people who aren’t yet in your network — including 2nd and 3rd+ degree connections.
You can send a connection request with or without a personalized message, all via a simple API call .

  • You must have already connected your LinkedIn account.

  • Include the X-AccountId header in the request.

  • You need to provide the profileId of the profile you want to connect with.

  • Use "message": null to send a blank connection request.

  • To send a personalized message, insert your custom text into the "message" field.
