In-Stream: How to implement In-Stream Part 3 - Testing the ad zone

After implementing the In-Stream ad zone, you might not see ads in the video. Why?

The most common reason is that the In-Stream ad zone is receiving an empty VAST response. When there is no video ad to show, our ad-server replies with an empty VAST XML as per the VAST 3.0 standard.

However, this does not necessarily mean that your in-stream ad zone is not working. In order to troubleshoot your player for VAST compatibility issues, you need to use one of the following test codes.

Test Codes

If your player displays ads with any of the codes above, then your integration has been made correctly. You can switch to your own ad zone and start monetizing your traffic. Remember that, even if you don't see ads in your current environment, users from other countries and devices will be monetized correctly.


Note: This is for testing purposes ONLY. Once you can see the pre-roll video is running correctly then you will have to replace the test zone id for your real ad zone id.
