NamedValue is not accessible in APIM

Hi @Sukhmeet Bhatia Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.

Just wanted to check if you have created the Named Value as Plain Value type or a Secret If someone else has created the Named Value as Secret, please ensure you have access to the Key-Vault where the secret is stored. Please refer the article Add a key vault secret to API Management for more information.

If you have defined a Plain Named Value, you should be able to access it by using {{}} per the documentation.

Here is an example of how a Named Value can be used

<set-header name="{{ContosoHeader}}" exists-action="override">
  <value>{{ContosoHeaderValue}}</value>
</set-header>

Notice that both ContosoHeader and ContosoHeaderValue are Named which are referenced in the above policy. If the Named Value is not accessed within the <value> tag, they need to be enclosed with double quotation.

If you still face additional issues, please share the type of Named Value you are trying to use and the policy statement through which you are accessing the named space.
