MRAID is injected by the ironSource Ads webview, so you can use MRAID methods detailed in the guidelines.

MRAID related requirements

  • Your MRAID file should not have any reference of the “DAPI initialization script” (see here for example) or DAPI in general as it may disrupt upload process.
  • Avoid accessing the top window object (it may cause an error) All URLs within the creative should be secured
    • Correct: HTTPS://
    • Wrong: HTTP://
  • Creatives should be contained in a single HTML index file, with no links to other files or folders
  • Ads are required to wait for the MRAID ready, stateChange events before starting playable content
  • To redirect a user on click, methods mraid.open(URL_STRING) or mraid.openStoreURL() should be used
  • The most recommended way to request mraid.js in MRAID ads is to directly include the <script src=”mraid.js”></script> tag within the <head> section of the HTML file.
    This ensures the mraid.js script is requested as early as possible during the loading of your ad creative.
