# VAST Wrapper Tag

As a Publisher, you receive a VAST wrapper tag response when your video player requests an ad that redirects to a secondary VAST response.

## XML Example

{% code expandable="true" %}

```xml
<?xml version="1.0" encoding="UTF-8"?>
<VAST version="3.0">
    <Ad id="1111111">

| `VASTAdTagURI`                           | Element is used to provide a URI to a secondary VAST response. This secondary response may be another Wrapper, but eventually a VAST wrapper must return an `<InLine>` ad. Version 3 doesn't limit the number of Wrapper redirections, but from Version 4, a maximum of 5 Wrapper VAST redirections are allowed. |
| `VideoClicks`                            | Element which is used to specify what the video player should do if the user clicks directly within the video player frame while the ad is being displayed. When a `<VideoClicks>` element is provided, it contains a single child `<ClickTracking>` element with URI (or `<ClickThrough>` in case of VAST Tag). |
| `ClickTracking`                          | Element is used to track the `clickthrough` when the creative file handles the `clickthrough`.                                                                                                                                                                                                                   |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.exads.com/publishers/vast/vast-wrapper.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
