Azure Functions Route binding with unknown URL

I’m trying to construct the function.json file where the url has a custom ending that we don’t know. This customer ending may include forward slashes so I can’t be guaranteed this will be one parameter. My current code :

    {
    "bindings": [
      {
        "authLevel": "function",
        "type": "httpTrigger",
        "direction": "in",      
        "route": "{param1}/customer/{param2}/{restOfUrl}",
        "name": "req",
        "methods": [
          "get"
        ]
      },
      {
        "type": "http",
        "direction": "out",
        "name": "res"
      }
    ],
    "scriptFile": "../dist/src/handlers/myScript.js"
  }

this works fine when for example the url is:

...123/customer/456/rest-of-url

however if the rest of the url contains forward slashes eg:

...123/customer/456/rest/of/url

I get a 404 not found.

How do I correctly define the route if the url is unknown and will likely include forward slashes / ?

    After trying the suggested solution I discovered this doc in Azure documentation. The solution was to * the remaining parameter which returns the remainder of the path as a string. The change looks as so :

     "route": "{param1}/customer/{param2}/{*restOfUrl}"

    There is an appsetting to disable the url encoding so that it will match a full path. By default slashes are encoded as %2F
