# Execute the function

A function can be executed by calling the `execute()` method in which the function ID and the configuration (of type dictionary) are passed as parameters. To know more about the component instance `function_service` used below, please refer to [this help section](https://docs.catalyst.zoho.com/en/sdk/python/v1/serverless/functions/get-component-instance/).

Before executing a function, you must set the configuration required for it. Here, the configuration specifies the function arguments and their values.

The unique functionID is passed as a parameter to the `execute()` method to call the function to be executed with the necessary configuration.

The configuration can be set using the following code snippet :

**Parameters Used**

<table class="content-table">
	<thead>
		<tr>
			<th class="w20p">Parameter Name</th>
			<th class="w20p">Data Type</th>
      <th class="w60p">Definition</th>
		</tr>
	</thead>
	<tbody>
		<tr>
			<td>`function_ID`</td>
			<td>Numeric</td>
			<td>A **Mandatory** parameter. Will store the unique ID the function to be executed.</td>
		</tr>
    <tr>
			<td>`function_config`</td>
			<td>Object</td>
			<td>A **Mandatory** parameter. Will store the configuration of the function to be executed.</td>
		</tr>
	</tbody>
</table>

```python
function_service = app.functions()
args = {"Name": "Amelia"}
return_value = function_service.execute(5249000000015567, args)

```

> **Info :** 

1. Refer to the [SDK Scopes table](https://docs.catalyst.zoho.com/en/sdk/python/v1/sdk-scopes) to determine the required permission level for performing the above operation.

2.  You can also pass the function name as a string to the `execute()` method instead of using the function ID.
