Configuration

PubMatic recommends the UserSync configuration below. Without it, the PubMatic adapter will not able to perform user syncs, which lowers match rate and reduces monetization.

pbjs.setConfig({
  userSync: {
    filterSettings: {
      iframe: {
        bidders: '*',      // '*' represents all bidders
        filter: 'include'
      }
    }
  }
});

Note: Combine the above the configuration with any other UserSync configuration. Multiple setConfig() calls overwrite each other and only last call for a given attribute will take effect.

adSlot Specification and Multi-Size Ad Units

The adSlot parameter supports two different formats:

Format Example
Without Size '38519891'
With Size '38519891@300x205'

adSlot parameter is optional. To omit the adSlot parameter, your publisher account must have default site and tag enabled. Consult your account manager to find out if default site and tag is enabled on your account. If used, both formats are supported. Without Size is the recommended option. Both options will send the ad request with all sizes specified in the Prebid ad unit configuration.
