The following topics walk you through the steps to add, edit, and delete advanced throttling policies.

Adding a new advanced throttling policy

Follow the steps below to add a new advanced throttling policy, which you can apply when publishing an API.

Note

Depending on your requirement, you can apply an advanced throttling policy either to the API or per API resource.

  1. Sign in to WSO2 API Cloud (https://api.cloud.wso2.com) as an admin user.
  2. On the top pane of the API Publisher, click Configure and then click Admin Dashboard.

    This takes you to the Admin Dashboard.
  3. On the left navigation pane, click THROTTLING POLICIES, and then click ADVANCED POLICIES. This displays the Advanced Throttling Policies screen with the existing policies.
  4.  Click ADD NEW POLICY.

    This displays the Add Advanced Throttle Policy screen.
  5. Specify appropriate values for each of the fields.
    • Under Default Limits, you will see two options, namely Request Count and Request Bandwidth. Select an option depending on your requirement. 
      For example, If you are using an API for file sharing or data transmission, select Request Bandwidth to limit the data bandwidth for a given time unit.

    • Under Conditional Groups, you can add a required condition to the throttling policy to apply a throttling limit based on a specified condition. 

       Click here for instructions on how to add conditional groups.
      1. Click Add Conditional Group.

      2. Click on the condition group to expand it, then select a required condition and turn it on. The conditions you can add are as follows:

        ConditionDescription
        IP ConditionAllows you to set a throttling limit for a specific IP address or a range of IP addresses.
        Header ConditionAllows you to set a throttling limit to specific headers and parameters. If you select this condition, you can specify a regular expression as the Param Value. The regex pattern can be specified to make either an exact match or a pattern match for the value.
        Query Param ConditionAllows you to set a throttling limit to specific query parameters.
        JWT Claim ConditionAllows you to set a throttling limit to specific claims. If you select this condition, you can specify a regular expression as the Param Value. The regex pattern can be specified to make either an exact match or a pattern match for the value.

        You can configure multiple condition groups when creating an advanced throttling policy. For example, if necessary it is possible to apply an IP condition and a query pram condition to the same advanced policy that you create.

      3. Specify appropriate values for each of the fields depending on the condition you selected.

      4. Under Execution Policy, specify appropriate values for the fields depending on your requirement.

        An execution policy is applicable only to the condition it is specified for. For example, if you select IP condition and set the request count as shown in the diagram given below, then only 5 requests are allowed per minute via the specified IP address. Any request that is not from the specified IP address falls to the default limit.

  6. Click Save. 

Now you have successfully added a new advanced throttling policy, which you can apply to an API or a resource.

If necessary, you can configure multiple conditional groups when defining an advanced throttling policy. For example, it is possible to apply an IP based condition together with a query param condition for a particular advanced throttling policy that you create.

Editing an existing advanced throttling policy

Follow the steps below to modify an existing advanced throttling policy depending on your requirement.

  1. Sign in to WSO2 API Cloud (https://api.cloud.wso2.com) as an admin user.

    This takes you to the Admin Dashboard.
  3. On the left navigation pane, click THROTTLING POLICIES, and then click ADVANCED POLICIES. This displays the Advanced Throttling Policies screen with the existing policies.
  4. Click Edit on the policy you want to modify.

    This displays the existing policy details so that you can do necessary changes.

  5. Edit the existing values depending on you requirement. 

    You can follow the steps provided in step 5 above to update the policy fields appropriately depending on your requirement.

  6. Click Update to save the modified policy.
