Webhook for Completed Payment

If you call CreatePayment with directly with the following it will trigger a webhook event with the customer_id:

{
    "idempotency_key": "{{$guid}}",
    "autocomplete": true,
    "amount_money": {
        "amount": 100,
        "currency": "USD"
    },
    "source_id": "cnon:card-nonce-ok",
    "customer_id": "{{customer_id}}"
}
