    Hi Anurag,

    How exactly did you try it? Can you post snippet of how it was defined in the API, how it was used in the API, as well as catalog names/titles you have?​

    AFAIK for 2018, catalog properties are applied only when you publish API with current property value, and not changing when you change property value. So it isn't really dynamic.

    I assume you expect properties values to change frequently, so you'll need to republish all APIs on property changes.

    But I clouldn't find this information in documentation right now, it's from hands-on experience.Somebody plz correct me, if I'm wrong.

    @Denis Migulin you are correct - you have to stage/re-publish the Product​ containing the API again for API properties changes to take effect.

    I will create an internal docs issue to update the API Connect documentation - thank you for checking.

    Unfortunately, that's a big pain point for some implementations. Unless you call an external service or use extensions, there is no way currently in the product to provide dynamic config values.

    Hi Denis,

    After Changing the catalog properties, we can republish the product still better option than changing target url individually as all the APIs inside product follows same domain whose version is changing(PFA of screenshot in which catalog property is defined where I am trying to change version).
    But catalog property values isn't accessible to me inside API.
    How is defined catalog property in my API -(cat_1.0.0.yaml)
    properties:
        empty: {}
    catalogs:
        Sandbox:
           properties: {}

    where empty is property define inside catalog named sandbox.
    and also what reference variable is required to access value of same property.

    I didn't quite understand the second part of your questions, but you can access your catalog property inside your API flow by using $(catalog-var-name)
    Use a set-variable policy to assign $(catalog-var-name) value to a new context variable e.g: target-url. Then use target-url context variable in your Invoke.

    Hi Romil,

    The name of catalog is 'sandbox' and variable name is 'empty' so reference i tried to get value $(sandbox-empty)/$(api.properties.empty)/$(apim-sandbox-empty) but any of them doesn't return value the which i defined in catalog.

    You don't have to specify the catalog name if your API is deployed/consumed in that catalog. Just use variable name : $(empty)
