# Malformed CTV bundle IDs

> Malformed and unidentified CTV bundle ID feed reference. What it contains, file name, schema, cadence and how to apply it to CTV traffic pre-bid.

The malformed and unidentified CTV bundle ID feed lists connected TV (CTV) bundle IDs that are malformed or that Pixalate can't map to a known app. These bundle IDs carry a high risk of app spoofing and lack transparency, so you can reject them before the bid.

Unmapped bundle IDs cause problems for targeting and post-bid reporting, and they can indicate fraud or spoofing. That affects buyers and every seller in the supply chain.

## File format and cadence

|                        |                                  |

| Format                 | CSV                              |
| File name              | `UnIdentifiedBundleIds_YYYYMMDD` |
| Update frequency       | Weekly                           |
| Estimated availability | 8:00 AM UTC                      |

## Schema

| Column         | Description                                                                          |
| -------------- | ------------------------------------------------------------------------------------ |
| `osName`       | The CTV operating system, for example `fireos`.                                      |
| `platformName` | The CTV platform, for example `amazon`.                                              |
| `bundleid`     | The malformed or unidentified bundle ID. Note the lowercase `id` in the column name. |

fireos,amazon,com.sample.unidentified.app
```

## Apply it pre-bid

You apply the feed in your own systems, so you choose the scope: all of your CTV traffic, or only some of it. Common uses:

* **Confirm the bundle ID before you buy.** Check that the inventory you're buying really runs on the bundle ID you intend, before the impression.
* **Block by platform.** Block specific bundle IDs on a given platform, and apply different rules to different supply paths or traffic partners.
* **Review delivered campaigns.** Check post-bid data for impressions that ran on unidentified bundle IDs, then troubleshoot with your partner or request clawbacks.
