Sets or updates the webhook URL and event subscription preferences for receiving automated, real-time notifications about platform events. Configure which events trigger webhooks (transaction completed, beneficiary verified, payment failed, balance updated, etc.), the HTTPS endpoint URL where notifications should be sent, and retry behavior. Your webhook endpoint must respond with 200 OK within 5 seconds and should validate webhook signatures using your webhook secret.
