Webhook to capture leads from Google Ads lead forms

In Google Ads, we can define an exporting webhook trigger, to send new lead form entries to any CRM with webhooks.

While investigating options with FluentCRM, I found that there is no individual mapping available. How would you suppose to capture leads from Google Ads lead forms?

Sample webhook payload:

{
"lead_id": "TeSter-123-ABCDEFGHIJKLMNOPQRSTUVWXYZ-abcdefghijklmnopqrstuvwxyz-0123456789-AaBbCcDdEeFfGgHhIiJjKkLl",
"user_column_data": [
{
"column_name": "User Email",
"string_value": "test@example.com",
"column_id": "EMAIL"
},
{
"column_name": "Full Name",
"string_value": "FirstName LastName",
"column_id": "FULL_NAME"
},
{
"string_value": "Example answer",
"column_id": "wie_viele_mitarbeiter_beschäftigen_sie?"
},
{
"string_value": "Example answer",
"column_id": "in_welcher_branche_sind_sie_tätig?"
}
],
"api_version": "1.0",
"form_id": 284082731522,
"campaign_id": 22824963093,
"google_key": "1",
"is_test": true,
"gcl_id": "TeSter-123-ABCDEFGHIJKLMNOPQRSTUVWXYZ-abcdefghijklmnopqrstuvwxyz-0123456789-AaBbCcDdEeFfGgHhIiJjKkLl",
"adgroup_id": 20000000000,
"creative_id": 30000000000
}
