# Get API Token

> This endpoint returns an api_token to open a Nexus session.

This endpoint returns an `api_token` to open a Nexus session. The `api_token` is one-time use and expires in ten minutes. A fresh `api_token` must be requested each time a Nexus session is initiated.

The endpoint will return a 404 response if the client does not have access to Nexus enabled. Please work with your account representative to add this functionality to the client.
