Please be advised that all MoPub Marketplace inventory requires fully secure creatives, as specified by the
bidrequest.imp.secure=1 field. This includes all creative resources, impression trackers, redirects, and the click through URL. This means that insecure network communication calls (http) may fail, resulting in blank ads, click through failures, discrepancies, and other ad serving issues.
To mitigate negative impact, where possible, MoPub will upgrade http calls to https. However, if the end server for the content does not support https, then the network call will still fail.
- Check that your bidder is reading and respecting the secure flag:
bidrequest.imp.secure=1. Note: All Marketplace bid requests will have this flag set to true (1).
- Ensure that all creative is fully secure, including all creative resources, impression trackers, redirects, and the click through URL(s).
- Test your creatives through the testing process to ensure that the ads render, the click through URL, and all click and impression trackers are firing.
- Make sure to test creatives of all sizes and formats including VAST, MRAID and Native on both iOS and Android.
