# How to Authenticate

After generating an [API Token](/authentication/create-and-manage-your-api-token.md#how-to-create-an-api-token), the system displays the associated Username and password for authentication, which is based on the Basic authentication method.

To retrieve the token value, navigate to `Sesame Data > API Tokens > [edit]`.

In your preferred tool, select the Authorization type as `Basic Auth`. Your tool will prompt you to enter the Username and Password. Please input the credentials as provided in the API Tokens tool.

The simplest call that you can make is [Entity List](/api-endpoints/entity-list.md), which contains all Legal entities, Portfolios and Groupings of your account. This endpoint does not include any additional request parameter.

Therefore the Authentication and a request to our APIs would require:

* Verb `GET`
* URL: [https://data.api.landytech.net/api/v1/entitylist](https://data.api.landytech.net/api/v1/entityList) [Entity List](/api-endpoints/entity-list.md)
* Authorization type: `Basic Auth`
  * Username: from `API Tokens`
  * Password: from `API Tokens`

Users also can troubleshoot the results by [Viewing Logs](/faq-and-troubleshooting/viewing-logs.md).
