+  Gets information about an Azure Function hosted in an FunctionApp.
+---
+
+# Data Source: azurerm_function
+
+Use this data source to access information about an Azure Function hosted in a Function App.
+
+## Example Usage
+
+```hcl
+data "azurerm_functions_key" "test" {
+  function_app_name   = "function_app_name_here"
+  resource_group_name = "resource_group_here"
+  function_name       = "name_of_function_you_want_key_for_here"
+}
+
+output "key" {
+  value = "${data.azurerm_function.test.key}"
+}
+```
+
+## Argument Reference
+
+* `function_app_name` - (Required) Specifies the name of the Function App in which the Function is hosted.
+* `function_name` - (Required) Specifies the name of the Function.
+* `resource_group_name` - (Required) Specifies the name of the resource group the Function App is located.
+
+## Attributes Reference
+
+* `key` - The Function Key
+* `trigger_url` - The full URL with Function Key used to trigger the function
