# RatePlan.recordEvent

The `recordEvent` method records `Events` against a defined `Account`, `AutoBill`, or `AutoBillItem`.

`recordEvent` will return an error if you attempt to pass in a negative amount.

**Note:** This method is a bulk interface, which allows up to 50 `Events` to be recorded in a single call.

## Input

*srd*: sparse response description, a SOAP string (which must be a JSON object), in which you specify the elements you want returned.This parameter enables the calling system to constrain a `method` call to return only components you specify. This gives you greater control over returned content, and improves response time within the Vindicia platform by reducing the processing needed for the call.

Some fields are required, either practically or in the WSDL, and will be returned regardless of the *srd*. A null *srd* returns the complete response.

*event*: the array of `Event` objects that you wish to record.

## Output

*return*: an object of type `Return` that indicates the success or failure of the call.

## Returns

This method returns the codes listed in [The Return Object](The_Return_Object#).

## Example

```

$rateplan = new RatePlan;
$event = new Event;

$event->setMerchantEventId('rating_129');
$event->set('ab_715');
$event->setAmount(2);

$response = $rateplan->recordEvent(array($event));
// check $response
```
