|
|
|
6 * In most cases when an app receives an Access Token, it will also receive an
|
|
|
7 * expires parameter which indicates when you can expect that token to expire.
|
|
|
8 * However, there are several events which can cause an access token to become
|
|
|
9 * invalid before its expected expiry time. Examples include: when a user
|
|
|
10 * changes their password, when a user de-authorizes an application, or when an
|
|
|
11 * App's Secret is reset.
