| description | Receive and acknowledge Zift (Zift Payments / payment gateway) webhook notifications. Use when setting up a Zift webhook receiver, understanding why there is no signature/HMAC header to verify, returning the required {"notificationId": ...} acknowledgement, or handling billing and processing events like billing.subscription-created, processing.chargeback, and processing.return.

Zift Webhooks
Zift (a payments platform / gateway) delivers notifications — billing and
processing events — to an HTTPS endpoint you register with Zift support. Each
delivery is a plain HTTPS POST with a JSON body. There is no signature,
no HMAC, and no auth header on the delivery. Instead, your endpoint proves it
received the notification by echoing the notificationId back in the response
body — that response is the acknowledgement, and skipping it triggers retries.
When to Use This Skill
- How do I receive Zift webhook notifications?
- How do I acknowledge a Zift webhook (the
{"notificationId": ...} response)?
- Why is there no
X-Zift-Signature / HMAC header to verify?
- How do I secure a Zift webhook endpoint with no signature?
- How do I handle Zift
billing.* and processing.* events (chargeback, return, NOC)?
- Why does Zift keep retrying / marking my webhook
Failed?
Verification & Acknowledgement (core)
There is NO per-message signature/HMAC header on Zift notifications. Do not
look for X-Zift-Signature, webhook-signature, or any Standard Webhooks
header — none exists, and Zift sends no Basic/token auth on delivery either.
Authenticity relies on the transport and endpoint secrecy:
- HTTPS only — publish the endpoint over TLS so the body can't be read or
tampered with in transit.
- Endpoint-URL secrecy — treat the path as a shared secret; use a long,
unguessable path.
- IP allowlisting (recommended) — restrict inbound to Zift's egress ranges
at your load balancer / firewall (confirm ranges with Zift support).
Because there is no body signature, ordinary JSON parsing is fine — the raw
bytes are not security-critical (unlike HMAC providers).
The critical part is the acknowledgement. To ACK a delivery your endpoint
MUST return a JSON body echoing the received notificationId (Zift accepts an
int or a string). Anything else — 200 OK, an empty body, {"received":true} —
is not an acknowledgement and triggers Zift's retry schedule.
function ackBody(payload) {
return { notificationId: payload.notificationId };
}
function eventCategory(eventCode) {
if (typeof eventCode !== 'string') return 'unknown';
const category = eventCode.split('.')[0];
return category === 'billing' || category === 'processing' ? category : 'unknown';
}

Payload Structure
Every notification shares the same envelope:
{
"notificationId": 272638,
"eventCode": "billing.subscription-created",
"eventDate": 1753670400000,
"dataType": "subscription",
"data": { }
}
| Field | Type | Meaning |
|---|
notificationId | int or string | Unique delivery id — echo this back to ACK |
eventCode | string | Dotted event name, e.g. billing.subscription-created |
eventDate | number | Event time in epoch milliseconds |
dataType | string | Describes the shape of data (e.g. subscription) |
data | object | Event-specific payload |
Common Event Types
Events are grouped by the eventCode prefix. Only billing.subscription-created
is documented verbatim; the others follow Zift's category.entity-action pattern
from the setup trigger names — confirm the exact literal strings with Zift
support at onboarding and dispatch on the billing / processing prefix.
eventCode | Category | Triggered when |
|---|
billing.subscription-created | billing | A recurring subscription is created |
billing.payment-option-created | billing | A payment option (method) is added |
billing.allocation-created | billing | A billing allocation is created |
billing.payment-processed | billing | A scheduled billing payment is processed |
processing.chargeback | processing | A chargeback is received |
processing.return | processing | An ACH/eCheck return occurs |
processing.reversal | processing | A transaction is reversed |
processing.noc | processing | An ACH Notice of Change (NOC) is received |
See references/overview.md for the setup trigger names
(subscription~create, payment-option~create, chargeback, NOC, …).
Retry Behaviour
If your endpoint does not acknowledge with the notificationId, Zift retries at
+5 min, +15 min, +60 min, +24 h, then marks the notification Failed
with no further redelivery. Make your handler idempotent — a retry may deliver a
notification you already processed.
Environment Variables
Zift sends no secret on delivery, so no signing secret is required. The only
optional config is your own comma-separated IP allowlist (enforced by your
infra, shown here for documentation):
ZIFT_ALLOWED_IPS=
Local Development
npx hookdeck-cli listen 3000 zift --path /webhooks/zift
Setup
Zift webhooks are configured out-of-band: email Zift support your HTTPS
endpoint URL and the events you want. Webhooks are set at the
integrator/reseller level, not per-merchant. See
references/setup.md.
