According to the tiers s/he selects, the subscriber is granted a maximum number of requests to the API.
Setting tier permissions
An API creator Users with
Manage Tiers permission can set role-based permissions to API-level access throttling tiers. This is done using the Tier Permissions tab of API Publisher as follows:
With this feature role based permissions for each Tier can be defined through the API Publisher. Then the API subscription Tiers are filtered based on the subscriber’s role.
In the API Publisher, new ‘Tier Permissions’ page allows defining the roles against each Tier.
This 'Tier Permissions' page will be visible to users with 'Manage Tiers' Permissions only.
Either you can define the Roles, ALLOWED for a Tier or DENIED for a Tier. By default all the Tiers are ALLOWED for everyone.
If you need to ALLOW a Tier to some roles only, then you can select “allow” and define those roles as a comma separated list. For each tier, you can specify a comma-separated list of roles and either Allow or Deny access to the list as shown below:
By default, all the Tiers are allowed for everyone.So only the subscribers who fall under those roles will be able to subscriber to APIs using that Tier.
Only subscribers who has role1 or role2 will be able to subscribe using Bronze Tier.
If you need to DENY a Tier to some roles, then you can select “deny” and define those roles as a comma separated list. So all the subscribers who fall under those roles will not be able to to subscriber to APIs using that Tier.
Subscribers Only subscribers who has role1 or role2 will not be able to subscribe using Bronze Tier. Others can subscriber using Bronze Tier.
In the API Store, when a user is subscribing to an API, the available Tiers will be filtered based on the subscribers role. So only the ALLOWED roles will appear here.
