This API allows you to Login to LiveEngage, as a user, using a username and password or as an application, using an API key. Once you login, a session token (Bearer) will be provided and can be used for relevant API calls.

This API provides endpoints for managing the User Session (User Login, Application Login, Logout and Refresh).

Here are the API terms of use.

When using this API, it is recommended that you implement our Retry Policy and KeepAlive best practices

Use Cases

User Login

Use this method when you need to provide a programmatic way for users to access and manage a LiveEngage session such as customized agent workspace or hosting a LiveEngage user in an external app.


  • Using the User Login method, logged in users will be managed under the same restrictions as normal users in LiveEngage, including (for example) password expiration, concurrent conversations limits, skill groups and so on.

  • Using the User Login method, if your account has SSO enabled, this method will not be standalone and you will have to register the relevant user through your hub to provide LiveEngage with an SSO SAML assertion.

Application Login

Use this method when you need to provide a programmatic way for applications to access and manage a LiveEngage session such as bots, virtual agents or any other app that needs to act as an agent in the LiveEngage.


  • The Application Login method overcomes both issues detailed above with the User Login method, for example password expiration or SSO integration_**.
