referral.* events

A full refund reversed a commission, or clawed back one the creator had already paid.

When this fires

A payment that had earned a commission was fully refunded or charged back, which Subscriby learns from the same gateway event that emits payment.refunded. A row never paid out is reversed in place; a row already paid is answered with a clawback, a second row carrying the negative amount, so the affiliate's balance drops and the creator's next payout nets it off.

A partial refund changes nothing. The creator kept most of the money, and the rule an affiliate can be told is the simple one: only a full refund takes a commission back. Days are never taken back.

Caveats

  • A redelivered refund writes no second clawback. The second delivery finds the rows reversed and the clawback written, and touches nothing.
  • A refund that names its payment touches that payment's commission only. One that names none unwinds every live commission on the subscription, which is what a refund of "the last charge" means.

Headers

SB-Signaturestring required

t=<unix seconds>,v1=<hex>: the HMAC-SHA256 of "<t>.<raw body>" under the endpoint's secret. Verify it before acting, and refuse a t more than 300 seconds from now. During a secret rotation a v0= signature under the previous secret may precede v1=.

SB-Event-Idstring required

The event's ULID, bare. The envelope's id is the same ULID prefixed evt_, so strip the prefix before comparing. Deduplicate on it: a retry carries the same id.

SB-Event-Namestring required

The event name, the same as the envelope's type.

Content-Typestring required

Always application/json.

User-Agentstring required

Always Subscriby-Webhooks/1.0.

Payload

idstring required

A ULID unique to the event, prefixed evt_. Every retry carries the same id, so it is the key to deduplicate on.

type'referral.reward_reversed' required

The event name, always referral.reward_reversed here.

created_atstring date-time required

When the event was emitted, server time, ISO 8601.

api_versionstring required

The contract version of the payload shape, 2026-05-01 today. A breaking change to a shape ships under a new version.

project_idstring uuid nullable required

The project the event belongs to; null for team-scoped and billing events.

Response

Your endpoint acknowledged the delivery. Any 2xx status within 30 seconds marks it delivered; the response body is ignored.

Changes

Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
