# Trigger Drop Processor

The Trigger Drop Processor is used to whiteout metadata during a trigger start/stop pair, with an optional timeout.

There are no default values.

| **Param Name** | **Mandatory** | **Description** | **Possible Value** |
| --- | --- | --- | --- |
| Key | Yes | Key to track for Start and Stop Triggers. | Not null. |
| Start Trigger | Yes | This value will start the whiteout. Could be a mask (VB-like syntax). E.g., `S*` will trigger the whiteout for messages `S01` and `S_P`. Stop Trigger has the same format. | Not null. |
| Stop Trigger | Yes * | This value will stop the whiteout. If no timeout is set, the whiteout will continue until Stop Trigger is received. | Not null. |
| Timeout | Yes * | Timeout in seconds if Stop Trigger is not received, or used without a Stop Trigger. | Numeric. |

* **Stop Trigger** and **Timeout** are each optional, but *one* of them is required for proper operation.

### Example Use

In the above example:

- A single Trigger Drop whiteout will be activated when `ad_type` equals `GAME_START`. The whiteout will end if `ad_type` equals `GAME_STOP`, or two hours (7200 seconds) has passed (whichever occurs first).
