# Execute a Function

> **Note:** This SDK is currently in deprecation. Migrate to [JavaScript SDK](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/serverless/functions/execute-function/) now.

A function can be executed by calling the _execute()_ method in which the function ID and configuration (of type JSON)
are passed as parameters. The _functions_ reference used in the code snippets below is the [component instance.](https://docs.catalyst.zoho.com/en/sdk/nodejs/v2/serverless/functions/get-component-instance)

#### Create a Function Configuration (JSON)

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

The configuration can be set using the following code snippet:

```javascript
//Create Configuration for function Execution 
let conf = { args: { Name: 'Amelia' } }
```

### Execute function

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

The promise returned here will be resolved to an object which is a JSON.

```javascript
let functions = app.functions(); 
//Call Function with the function ID and the configuration 
let promiseResult = functions.execute(1510000000059262, conf); 
promiseResult.then((functionResponse) => 
{ 
console.log(functionResponse); 
});

```

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