// To obtain User Info, you have to follow three steps in general.
// First, you need to obtain user's consent to retrieve the information you want.
// This is explained in the example "ObtainUserConsent.php".

// Once you get the user's consent, the end result would be long lived refresh token.
// This refresh token should be stored in a permanent storage for later use.

// Lastly, when you need to retrieve the user information, you need to generate the short lived access token
// to retreive the information. The short lived access token can be retrieved using the example shown in
// "GenerateAccessTokenFromRefreshToken.php", or as shown below

// You can retrieve the refresh token by executing ObtainUserConsent.php and store the refresh token
