    Hi Experts,
    I have a requirement to pass different query parameters to back end url in policy. here are the examples of back end url's. sometimes there should be one query parameter and sometimes 2 or more.

    https://hostname/orders?orderId=8416531&pageSize=10&pageNo=1
    https://hostname/orders?orderStartDate=08-11-2019&orderEndDate=08-18-2019&orderStatus=E&pageSize=10&pageNo=1
    https://hostname/orders?jaOrderId=148371&storeId=1101&pageSize=10&pageNo=1

    i do not want to use save each parameter in context variable. is there a way to configure in layer 7?

    Thanks,
    Sri

    Hi Sri,

    If you want to pass all of the query parameters from the request to the backend service, you can append the variable ${request.url.query} to the end of your backend url in the routing assertion like: https://backendhostname/orders${request.url.query}

    You've got a few options:

    1. As previously noted, you can just pass through the query string in the request as-is with ${request.url.query}.
    2. You can build a query string from specific query string parameters with ${request.https.parameter.<param name>}.
    3. You can build a query string using hard-coded values using whatever you want.
