Bid Params

Name Scope Description Example Type
adUnitID required Ad Unit ID provided by Holid '12345' string


To increase the match rate and monetization, Holid recommends turning on iframe-based user sync.

    userSync: {
        filterSettings: {
            iframe: {
                bidders: '*',   // '*' means all bidders
                filter: 'include'
