<Warning>
  As of Cognigy.AI 4.97.0, the Handover Providers section in the Endpoint settings is deprecated. From Cognigy.AI 2026.4 on, the Handover Settings section in the Endpoint settings is in read-only mode. You can't use this section to configure new handover providers. You can still view configured handover provider settings, but you can't change them.
  To configure handover providers, use the [Handover Providers](/ai/escalate/migration) interface, which offers greater flexibility for managing your integration with contact centers.
  For a smooth migration, refer to the [migration guide](/ai/escalate/migration).
</Warning>

The LINE Endpoint enables you to connect your AI Agent to the [LINE platform](https://www.line.me/).

## Prerequisites

* Access to [LINE Developer Console](https://developers.line.biz/console/).

## Restrictions

* The LINE Messaging API requires you to follow rules that might block some messages. Check your Node settings with the [Line Messaging API requirements](https://support.cognigy.com/hc/en-us/articles/5721825020444) to ensure all messages are delivered.
