Get Azure Function keys from an Azure Function at deployment time?

Question

I\'m sending an email in Azure Functions using the SendGrid bindings. As part of the contents of that email, I\'d like to include a link to one of the HTTP methods in the Azure

Answer 1

try the following two steps:

1. get the host master key:

   GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourcegroupName}/providers/Microsoft.Web/sites/{functionApp}/functions/admin/masterkey?api-version=2016-08-01
   

2. Get the function keys:

   GET https://{functionApp}.azurewebsites.net/admin/functions/{functionName}/keys?code={masterKeyFromStep1}
   

response from the step 2:

    {
      "keys": [
        {
          "name": "default",
          "value": "xxxxxxxxxxxxxxxxxxxxxx"
        }
      ],
      "links": [
        {
          "rel": "self",
          "href": "https://myFncApp.azurewebsites.net/admin/functions/myFunction/keys"
        }
      ]
 }

Update:

Note, that the step 1 requires an authorization header in the format:

Authorization: Bearer bearerToken

where a bearerToken string can be obtained from Azure Active Directory (AAD), see the following code snippet of the example:

    private string AccessToken(string clientID)
    {
        string redirectUri = "https://login.live.com/oauth20_desktop.srf";
        authContext = new AuthenticationContext("https://login.windows.net/common/oauth2/authorize", TokenCache.DefaultShared);
        var ar = authContext.AcquireTokenAsync("https://management.azure.com/", clientID, new Uri(redirectUri), new PlatformParameters(PromptBehavior.SelectAccount)).Result;
        return ar.AccessToken;
    }

Note, that the clientID is the quid of your registered application in the AAD with an API access permission for Windows Azure Service Management API.
