+description: |-
+  Gets information about an existing Function App.
+
+---
+
+# Data Source: azurerm_function_app
+
+Use this data source to access information about a Function App.
+
+## Example Usage
+
+```hcl
+data "azurerm_function_app" "example" {
+  name                = "test-azure-functions"
+  resource_group_name = "${azurerm_resource_group.example.name}"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - The name of the Function App resource.
+
+* `resource_group_name` - The name of the Resource Group where the Function App exists.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - The ID of the Function App
+
+* `app_service_plan_id` - The ID of the App Service Plan within which to create this Function App.
+
+* `app_settings` - A key-value pair of App Settings.
+
+* `connection_string` - An `connection_string` block as defined below.
+
+* `default_hostname` - The default hostname associated with the Function App.
+
+* `enabled` - Is the Function App enabled?
+
+* `site_credential` - A `site_credential` block as defined below, which contains the site-level credentials used to publish to this App Service.
+
+* `outbound_ip_addresses` - A comma separated list of outbound IP addresses.
+
+* `possible_outbound_ip_addresses` - A comma separated list of outbound IP addresses, not all of which are necessarily in use. Superset of `outbound_ip_addresses`.
+
+---
+
+The `connection_string` supports the following:
+
+* `name` - The name of the Connection String.
+* `type` - The type of the Connection String. 
+* `value` - The value for the Connection String.
+
+---
+
+The `site_credential` block exports the following:
+
+* `username` - The username which can be used to publish to this App Service
+* `password` - The password associated with the username, which can be used to publish to this App Service.
+
+### Timeouts
+
+~> **Note:** Custom Timeouts are available [as an opt-in Beta in version 1.43 of the Azure Provider](/docs/providers/azurerm/guides/2.0-beta.html) and will be enabled by default in version 2.0 of the Azure Provider.
+
+The `timeouts` block allows you to specify [timeouts](https://www.terraform.io/docs/configuration/resources.html#timeouts) for certain actions:
+
+* `read` - (Defaults to 5 minutes) Used when retrieving the Function App.
