Vungle will return an error if any of the above requirements are not met.

Endcards (CompanionAds)

We encourage all DSP partners to run endcards to increase performance. VAST-capable inventory supports companion ads, or endcards.


In the VAST response, inside the <CompanionAds> element and define at least one <Companion> node with the desired resource file information for the endcard. The resource file can be of type <StaticResource> or <HTMLResource>.


The following is an example of a static image endcard.

Sample Code

        <StaticResource creativeType="image/jpeg">
            < [CDATA[https://Your_endcard_image_url]]>  // Required
            <Tracking event='creativeView'>
                < [CDATA[https://endcard_tracking]]>  // Required
            < ![CDATA[https://endcard_click_through]]>  // Required
            < ![CDATA[https://endcard_click_tracking]]> // Required


The following is an example of an HTML endcard.

Sample Code

    <div>Your end card content</div> // Content can not be empty
    <script src=""></script>
            <Tracking event='creativeView'>
                < ![CDATA[https://endcard_tracking]]> // Required


HLS streaming is supported on iOS versions >= 11 for fullscreen inventory only. HLS is not supported for mrec video. Vungle Exchange will pass the value '1' in the field of the bid request to indicate that a bid request is eligible for streaming. Please do not respond to bid requests with streaming video unless they support streaming.

If bidding on steaming eligible inventory with streaming video, make sure to include the following in the bid response:

  • MIME type (type) must be must be application/x-mpegURL
  • Delivery should be passed as streaming
  • Media file URI extension must be .m3u8
  • If you provide multiple .mp4/.m3u8 media files in the VAST, we will pick the first valid media file

VAST Error Code

Vungle Exchange supports VAST error codes on VAST 2.0 and 3.0. Additionally, Vungle Exchange displays VX Error Message on the Vungle Exchange DSP Demo App to give DSP more details for creative troubleshooting.

The following example is a sample VAST response that includes the <Error> element for an inline ad.



  • The error tracking URL must use 'https'. 'http' is not accepted.
  • If the error_code parameter is provided, the macro [ERRORCODE] is case-sensitive.
  • If a VAST file triggers multiple errors, we report the first error with the IAB Error Code, and we list all the errors with the VX Error Message on the Vungle Exchange DSP Demo App.

The following error codes are supported by Vungle Exchange:
