Callback Feature

Updated: May 21, 2026
The callback feature allows users to submit their contact information (e.g., name, phone number) from your call ad. You can then download the callback requests.

Create a callback ad

To enable the callback feature on a call ad, add callback_type": "FORM" in call_ads_configuration when creating the ad creative.
"asset_feed_spec":
  {
  "call_ads_configuration":
    {
      "callback_type": "FORM"
    }
  }

Download callback requests

Use the bulk read by leads endpoint. Note that for callback requests, it can only be read by an ad, not by a form.
curl -X GET \
  -d 'access_token=<ACCESS_TOKEN>' \
