Is there a builtin APIM context variable that will list all the request headers?
I find there is a built in context variable which will list the header and value if I know the name of the header. My requirement is to list all the headers and possibly their values in the request object and response object .

    @Martin Kallukalam Thanks for reaching out. Yes, the context.Request.Headers context.Response.Headers variable provides access to all the request/response headers.

    You can indeed iterate over the context.Request.Headers dictionary to list all the request headers and their values.

    <set-variable name="allHeaders" value="@(string.Join(", ", context.Request.Headers.Select(h => h.Key + ": " + h.Value.FirstOrDefault())))" />

    This policy sets a variable allHeaders that contains a string with all the headers and their values, separated by commas. The FirstOrDefault() method ensures that you get the actual value of each header.

    do let me know incase of further queries, I would be happy to assist you.
