member.* events

A subscriber connects a platform account to their membership.

When this fires

A member of the project gains a connected account on a connector: the platform account that signs them in to the portal and that the project's bot knows them by. Three doors raise it: the member completes Connect … from the portal's Account & Recovery screen and the project's bot confirms the account; the member signs in to the portal through a connector the project had not seen them on before; or the member taps Use the same account to adopt an account they already use in another of the creator's projects. Each connected account emits its own event. Nothing is emitted when an account the member already holds is confirmed again.

Caveats

  • identity_id is the account row, not the link: the same value appears in member.identity_unlinked and in the identities of the member endpoint. The link's own id (what the disconnect endpoint takes) is only in the REST payloads.
  • Accounts the bot creates on first contact are mirrored into the identity tables without raising this event; it is reserved for acts the member takes.

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'member.identity_linked' required

The event name, always member.identity_linked 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.
