  • 1.  Rate limit policy to pass object name Dynamically

    Posted 11/28/25 04:21 AM

    Dear team,
    I want to use assembly rate limiting without a client ID. I have already created the assembly rate limit objects on DataPower. I have three different rate limit objects, for example: Client1, Client2, Client3. Each of these objects has different rate limits. These values (Client1, Client2, Client3) in the payload. How can I pass this value to as limit name in rate limit policy?

    I have tried this but getting and error "Rate limit $(serviceId) is in rate limit assembly action
    cbuae_sandbox_singleurlservice_1.0.1_ratelimit_0 but not in API gateway Stg-Int01". 

    why is not assigning the variable value?
    kindly guide me how to do this.
    Thankyou

    The rate limit name in the above field cannot be a variable; it must be a literal string that corresponds to a rate limit defined on the gateway.

    Dear Chad Petty,
    Thank you. Could you please let me know if there is a method to pass a variable? Any guidance would be appreciated

    There is no way to make rate limit name a variable. Check out the other answers on this thread, I think they are pointing you in the right direction.

    Hi,

    This blog might be helpful wrt setting up the rate-limit as an assembly-rate-limit in the Product-Plan.
    Also shows how you can use dynamic values for the rate limiting.

    https://community.ibm.com/community/user/blogs/amit-kumar-singh/2025/04/30/ibm-apic-connect-applying-rate-limit-based-on-dyna

    This DataPower functionality is explained here (although the parameters APIC side and the DataPower side aren't a perfect match cache-only vs cache-first for example).

    Dear Nick Cawood
    I have tried this, but the issue is that I need to pass the name as a variable

    Sorry, I don't understand your use-case.

    Why are you passing the rate-limit name as a variable?
    The rate-limit name must be a constant which is referenced in the Product-Plan - this is how the rate-limit definition is set for that API in the published Product.
    You can set multiple Plans with different rate-limits referencing the rate-limit name in the API and subscribe different Apps to each different Plan.

    If you want the rate-limit to be dependent to a specific dynamic variable then that must be then added to the Product-Plan syntax as per the blog.

    What are you trying to do?

    Hi Nick Cawood
    need to configure the Assembly rate limit without relying on clientId. The rate-limit name should be generated dynamically from the payload's client1 value (e.g., CCMSRQ001).

    The name of the rate-limit must be constant and be the same in the API and the Product-Plan.
    If you want the client1 value to relate to a different rate-limit then that must be designed outside of the API instead creating multiple Plans in the Product related to the rate-limit name. Then programmatically subscribe the different client1s to the Plan relating to the required rate-limit.

    The rate-limit is not set in the API.
    The rate is set in the Product-Plan.
    How you link the API to the rate is via the name of the rate-limit.
    Therefore you can have multiple rate-limits / Product-Plans assigned to the same rate-limit name / API.
    Which Plan an App subscribes to defines the rate-limit chosen.

    As for "not relying on client-id" are you suggesting that multiple Apps subscribe to the same Product-Plan and all those Apps can use up the calls of the rate-limit simultaneously?
    If so in the Product-Plan set "use-client-id false".
    However I'm not sure that's what you mean.

    I think you need to have a clear design for what you want to achieve and then you can use the functionality to achieve that.

    Some of what you want to achieve may not be possible - i.e. deciding which rate-limit to apply based on a variable, the code that invokes the API will need to decide that.
