Upon token generation, clients will receive their unique password. This password and their client-specific username are required as authentication when making requests.


Username	A unique code belonging to each client. This will be available in the Developer portal.
Password	The token which allows you to make requests. This is generated in the Developer portal.

In this section of the documentation, you will find information about how to create and manage your tokens and how to use your token to authenticate. Additionally, the API provides support for IP whitelisting, enhancing data security by restricting authentication to a predefined list of IPs. This feature ensures that only authorized IPs can authenticate by presenting a valid token. You may also find it valuable to explore our tutorial on [Using Sesame Data with Postman](/tutorials-recipes/using-sesame-data-with-postman.md).
