API Manager admins can add new throttling tiers and define extra properties to throttling tiers using the management console as discussed below. For a description of throttling tiers, see API-level throttling.
- Log in to the API Manager's Management Console and select Browse under Resources menu.
- Select the file:
In the Contents panel, click Edit as text link and the throttling policy opens.
You can add a new policy configuration by editing the XML code. For example, we have added a new tier called

Tier DisplayName : You can add this optional attribute to each throttle ID of tiers.xml file in order to decouple the throttle policy name defined in tiers.xml from the tier name showing in APIPublisher/Store UIs. That is, a user can add a different throttle display name to appear in APIPublisher/Store UIs without changing the throttle ID policy name. The configuration below has a displayName as
platinofor the throttle value
platinum. This value is displayed in APIPublisher/Store apps.
Tier Attributes : In the configuration below, there's a commented out XML section starting from the XML tag
<throttle:Attributes>. You can use it to define additional attributes related to each throttling tier definition. For example, if the throttling tier
Platinumhas attributes called
Availability, first uncomment the
<throttle:Attributes>section and then define the new attributes as follows:
After the edits, click Save Content. Your new throttling policy (Platinum) is now successfully saved in the Repository used by WSO2 API Manager. You can view this new throttle tier available for selection when creating a new API through the API Publisher.
