Question

Actually I'm trying to re-new a quota for specific client because he exceed the quota, but in same time i don't want to reset it for all client only for this one , Also without changing the subscription key .

the code below is not working fine i try to test it , does not reaching the limit exactly sometimes reaching more than the quota and sometimes less than and it's not small different it's huge different

<choose>
        <when condition="@(context.Subscription.Id == "")">
            <quota-by-key calls="20" renewal-period="500" counter-key="@(context.Subscription.Key)" />
        </when>
   <otherwise />
</choose>

Answer 1

I have used the same policy at my end by creating a new subscription key and it worked as expected for me.

Please verify if you are using the correct subscription id. By default, APIM takes the Built-in all-access subscription subscription key if you haven't provided ocp-apim-subscription-key in the request header for any other subscription key. For Built-in all-access subscription, subscription id value is master.

You can check the subscription key name and id which is being used by your API with the help of below policy-

<set-variable  name="ID"  value="@(context.Subscription.Id)"  />
<set-variable  name="Name"  value="@(context.Subscription.Name)"  />

You can see the values in Trace

Policy

<choose>
<when  condition="@(context.Subscription.Id== "test")">
<quota-by-key  calls="2"  renewal-period="300"  counter-key="@(context.Subscription.Key)"  />
</when>
</choose>
