Supported Ad Markup and Protocol

The Vungle Exchange supports VAST, MRAID and HTML creatives. Refer to the HTML & MRAID Creative Submission Guidelines and VAST Integration Guide for more details.

When pasting your bid response or ad markup into the demo app, either use code block, or paste from a saved TXT file. Pasting from email or a messaging app may cause formatting errors.

GDPR and CCPA in the Demo App

We set GDPR and CCPA to opt_out. Most of the DSP demo app request body fields are hard-coded. We follow OpenRTB 2.5 protocol and the request body has been minified. All optional privacy information has been removed from the request body.

AdMarkup Only Mode

Toggle on AdMarkup Only mode within the test app by clicking on the settings gear in the upper right corner of the app. When using AdMarkup Only mode, you don't need to test a full bid response. Instead, you can simply paste in the ad markup you want to test. Make sure the ad markup is escaped before testing in the test app.

Not Supported in the Demo App

SKAdnetwork attribution for iOS: the demo app does not include any SKAdNetwork IDs in plist.


Untrusted Enterprise Developer

If your iOS device throws this error, follow Step 2 in Install the Demo App to trust the Vungle, Inc. certificate.
