The OAuth 2.0 Refresh Access Token filter enables an OAuth client to get a new access token using a refresh token. This filter supports the OAuth 2.0 Refresh Token flow. After the client consumer has been authorized for access, they can use a refresh token to get a new access token (session ID). This is only done after the consumer already has received an access token using either the Web Server or User-Agent flow. For more details on supported OAuth flows, see API Gateway OAuth 2.0 Authentication Flows.

Configure the following fields on the this tab:
Access Token will be stored here:
Click the browse button to select where to cache the access token (for example, in the default OAuth Access Token Store). To add an access token store, right-click Access Token Stores, and select Add Access Token Store. You can store tokens in a cache, in a relational database, or in an embedded Cassandra database. For more details, see the section called “Managing Access Tokens and Authorization Codes”.
Access Token Expiry (in secs):
Enter the number of seconds before the access token expires. Defaults to 3600
(one hour).
Access Token Length:
Enter the number of characters in the access token. Defaults to 54.
Access Token Type:
Enter the access token type. This provides the client with information required to use
the access token to make a protected resource request. The client cannot use an access
token if it does not understand the token type. Defaults to Bearer.
Include Refresh Token:
Select whether to include a refresh token. This is a token issued by the Authorization Server to the client that can be used to obtain a new access token. This setting is selected by default.
Refresh Token Expiry (in secs):
When Include Refresh Token is selected, enter the number of seconds
before the refresh token expires. Defaults to 43200 (twelve hours).
Refresh Token Length:
When Include Refresh Token is selected, enter the number of characters
in the refresh token. Defaults to 46.
Store additional Access Token parameters:
Click Add to store additional access token parameters, and enter
the Name and Value in the dialog (for example,
Department and Engineering).
The settings on this tab configure service-level monitoring options such as whether to store usage metrics data to a database. This information can be used by the web-based API Gateway Manager tool to display service use, and by the API Gateway Analytics tool to produce reports on how the service is used. For details on the fields on this tab, see the section called “Monitoring” in OAuth Access Token Information.
