Adding an Excluded App or Tenant¶
Scenario¶
If you want to control the number of API calls received from a specific app or tenant, add an excluded app or tenant to a request throttling policy.
Prerequisites¶
You have created an app or obtained an app ID of another account or an account ID.
Adding an Excluded App¶
Log in to the management console.
In the navigation pane, choose Dedicated Gateways. Then click Access Console in the upper right corner of a dedicated gateway.
In the navigation pane, choose API Publishing > Request Throttling.
Click the name of the target request throttling policy.
On the displayed request throttling policy details page, click the Excluded Apps tab.
Click Select Excluded App.
Select an app to exclude. You can use one of the following methods:
To select an existing app, click Existing, select an app, and enter a threshold.
To select an app of other tenants, click Cross-tenant, and enter the app ID and a threshold.
Note
Excluded app thresholds take precedence over the value of Max. App Requests.
For example, a request throttling policy has been configured, with Max. API Requests being 10, Max. App Requests being 3, Period being 1 minute, and two excluded apps (max. 2 API requests for app A and max. 4 API requests for app B). If the request throttling policy is bound to an API, apps A and B can access the API 2 and 4 times within 1 minute, respectively.
Adding an Excluded Tenant¶
Log in to the management console.
Hover the mouse pointer over the username, click the username, and choose My Credentials from the drop-down list.
On the My Credentials page, view the account ID and project ID.
In the navigation pane, choose Dedicated Gateways. Then click Access Console in the upper right corner of a dedicated gateway.
In the navigation pane, choose API Publishing > Request Throttling.
Click the name of the target request throttling policy.
Click the Excluded Tenants tab.
Click Select Excluded Tenant.
In the Select Excluded Tenant dialog box, set the parameters listed in Table 1.
Table 1 Excluded tenant configuration¶ Parameter
Description
Account ID
Account ID or project ID obtained in 3.
Enter a project ID if you will bind or have bound this policy to an API that uses app authentication.
Enter an account ID if you will bind or have bound this policy to an API that uses IAM authentication.
Threshold
The maximum number of times an API can be called by the tenant within a specified period.
The value of this parameter cannot exceed that of Max. API Requests.
Click OK.
Note
Excluded tenant thresholds take precedence over the value of Max. User Requests.
For example, suppose a request throttling policy is configured, with Max. API Requests being 10, Max. User Requests being 3, Period being 1 minute, and two excluded tenants (max. 2 API requests for tenant A and max. 4 API requests for tenant B). If the request throttling policy is bound to an API, tenants A and B can access the API 2 and 4 times within 1 minute, respectively.
