# Add

Add a new key-value pair to the record.


## Example

This example shows how to use the Add transformation to add a new key-value pair to a record.

```json
{
    "operation": "add",
    "arguments": {
		"key": "new_field",
		"value": "new_value"
	} 
}
```

Given the input record:

```json
{
    "existing_field": "existing_value"
}
```

The output record will be:

```json
{
    "existing_field": "existing_value",
    "new_field": "new_value"
}
```
