## Enhanced Ads (Google only)

    <Card title="Off (Default)">

    </Card>

    <Card title="On">

  </CardGroup>
</Card>

## Asynchronous Requests

Requests are handled seamlessly in the background, allowing for you to collect responses at a later more convenient time via a designated endpoint, increasing stability, flexibility, and efficiency.

<Tip>
  ### Whitelist our webhook IPs

  Our asynchronous webhooks delivery sends notifications from a pair of stable IP addresses:

  1. `100.27.150.189`
  2. `18.214.10.85`

  Customers may need to whitelist these IPs on their side.
