How to remove the word ‘api’ from Azure functions url

Question

When you create an Http triggered API, Azure function hosts it on

https://[function-app-name].azurewebsites.net/api/[Route-configured-in-application]

Is there any way of getting rid of the term api from the URL and make it look like:

https://[function-app-name].azurewebsites.net/[Route-configured-in-application]

Answer 1

The Azure Functions v2 solution is covered in this answer, the http bit needs to be wrapped in an extensions property.

{
  "version": "2.0",
  "extensions": {
    "http": {
      "routePrefix": "customPrefix"
    }
  }
}

Answer 2

Edit the host.json file and set routePrefix to empty string:

{
  "http": {
    "routePrefix": ""
  }
}

Answer 3

The accepted answer no longer works if you're using version 2 functions, instead you need to put the http settings in an extensions property:

"extensions": {
    "http": {
        "routePrefix": ""
    }
}

You can get caught out looking at the hosts.json reference because if you only look at the http section it shows just the http properties so make sure to check the start of the doc for the top level hosts.json format.
