# Track Instant Event

> Send events immediately to Zeotap without waiting for the batch queue.

<Warning>
  **Important:** Please ensure your CMP configuration includes new **Vendor ID 1469** for 1st Party data tracking. Additionally, include **Vendor ID 301** if cookie sync is enabled. [Learn more](/articles/sdks/web-js/configurations/consent-options#shouldcheckzeotapvendorconsent)
</Warning>

The `setInstantEventProperties` method sends an event immediately to Zeotap, bypassing the normal batching queue. Use this for high-priority events that need to be delivered without delay.

## Syntax

```java theme={null}
Collect.getInstance().setInstantEventProperties(String eventName, Map<String, Object> eventProperties, SDKCallback callback)
```

## Parameters

| Parameter       | Type                  | Required | Description                          |
| --------------- | --------------------- | -------- | ------------------------------------ |
| eventName       | `String`              | Yes      | The name of the event to track       |
| eventProperties | `Map<String, Object>` | No       | Key-value pairs of event properties  |
| callback        | `SDKCallback`         | No       | Callback function to handle response |

## Usage Examples

### Simple Instant Event

```java theme={null}
Collect.getInstance().setInstantEventProperties("payment_completed");
```

### Instant Event with Properties

```java theme={null}
Map<String, Object> eventProperties = new HashMap<>();
eventProperties.put("transaction_id", "TXN-12345");
eventProperties.put("amount", 99.99);
eventProperties.put("currency", "USD");

Collect.getInstance().setInstantEventProperties("payment_completed", eventProperties);
```

### With Callback

```java theme={null}
Map<String, Object> eventProperties = new HashMap<>();
eventProperties.put("transaction_id", "TXN-12345");
eventProperties.put("amount", 99.99);

Collect.getInstance().setInstantEventProperties("payment_completed", eventProperties, (response) -> {
    // Handle response
});
```

## When to Use

* **Critical conversion events** (purchases, sign-ups) where real-time delivery matters
* **Time-sensitive events** that need immediate processing
* **App termination events** where the batch queue may not have time to flush
