Callback Event

You can use BSANativeCallback function to retrieve the attributes from the request. Here is the list of attributes you can access through this callback.

Attribute	Note
type	The ad format rendering type
key	The zone key for the request
segment	The segment or placement of this request
options	The value of options you pass into `_bsa.init`
ads	The response from the request

Handling empty ads

You can check the length of of the ads to see whether the API has returned any ads. Here is an example:

function BSANativeCallback({ ads, key }) {
  console.log(JSON.stringify(ads, null, 2))
  console.log(`${ads.length} ad(s) was served in zone ${key}`)
  if (ads.length === 0) {
    // Do something here to display fallback banner
  }
}
