Configuring an API-specific rate limit policy

Configure a rate limit policy for a managed API or custom API by assigning a general API-specific tier that applies to all users that access the API. You can also assign tiers to specific users. User-specific tiers determine the access policies of the user that you assign them to and override the general API-specific tier.

On the

API Registry

page, select an API.

The API details window appears.

Select the

Policies

tab.

If no tiers are defined, click

Tier Setup

and create tiers.

Select

Enable API-specific rate limit policy

To assign a general API-specific rate limit policy, select a rate limit tier for the API from the

Tier

list. Select how to assign the tier:

To assign a rate limit tier that applies to all users, select

Shared by all users

and click

Save

. All users share the rate limit that you select.

To assign a rate limit tier that applies to each user individually, select

Allocated per user

and click

Save

. Each user is allocated the rate limit that you select.

To assign a user-specific rate limit policy to a specific API user, expand the

User-specific Tiers

area.

Enter the user name in the

User Name

field, select a tier from the

Tier

list and click

Add

You can assign only one tier to each user.

Assign tiers to as many users as required.

Click

Save

To disable the rate limit policy for the API, clear the option

Enable API specific rate limit policy

and click

Save
