Webhooks: Connect Zapier, Make, n8n & Slack

Send an event to another app the moment something happens — add every approved ID to a Google Sheet, post on Slack when an order is held for an age review, or update your CRM. Open Age Verification → Integrations & Access.

Add a webhook

1. Create a catch URL in your app — in Zapier use Webhooks by Zapier → Catch Hook, in Make a Custom webhook, in n8n a Webhook node.
2. Click + Add webhook, paste the URL and tick the events you want.
3. Save, then click Send test event. The result appears under Recent deliveries.

You can add up to 5 webhooks; https:// addresses are recommended.

Events

Payload

}

Visitor events also include country and a masked IP (ip_masked). Headers: X-AVP-Event, X-AVP-Delivery and X-AVP-Signature.

Verify the signature

Every request is signed with your signing secret: X-AVP-Signature: sha256=HMAC-SHA256(raw body, secret).

$expected = 'sha256=' . hash_hmac('sha256', file_get_contents('php://input'), $secret);
if (! hash_equals($expected, $_SERVER['HTTP_X_AVP_SIGNATURE'] ?? '')) {
    http_response_code(401); exit;
}

Note: Webhooks are sent after the visitor's page has loaded, so they never slow your site down.
