project.archived

When this fires

A project is archived through POST /v1/projects/{project}/archive or the MCP archive_project tool. Archiving from the dashboard does not emit this event. The only state change is the project's active flag flipping to false; existing subscriptions and the public landing page are untouched.

Caveats

Archive is reversible; pair with project.restored for the inverse transition.
Subscribers retain their existing access until their ends_at ticks over. Expect subscription.expired events to follow as those subscriptions wind down.
Hard-delete fires project.deleted instead and is final.

Related events

project.restored: paired transition.
project.deleted: terminal state, replaces archive when the row is hard-deleted.

Ability to subscribe

project:view

A token needs this to subscribe an endpoint to the event.

Header Parameters

SB-Signature*string

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-Id*string

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-Name*string

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

Content-Type*string

Always application/json.

User-Agent*string

Always Subscriby-Webhooks/1.0.

Payload

JSONWhat Subscriby posts to your endpointapplication/json

The signed JSON envelope posted to your endpoint.

The envelope every event is delivered in.

id*string

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

type*"project.archived"

The event name, always project.archived here.

Value in

"project.archived"

created_at*string

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

Formatdate-time

api_version*string

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

project_id*|

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

Formatuuid

data*

The event-specific payload. Keys that do not apply to a given emission are omitted rather than sent as null, so check for presence.

Responses

2XXAny success status

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

defaultAny other status

Any other status, a connection failure, or no answer within 30 seconds counts as a failed attempt. The delivery is retried 8 times, after 10 seconds, 30 seconds, 2 minutes, 10 minutes, 1 hour, 6 hours, 1 day, 3 days; the last failure dead-letters it, and it can be retried from the dashboard or POST /v1/webhook-deliveries/{delivery}/retry. After 20 consecutive failures the endpoint is paused until it is resumed.

Delivery to your endpoint

Subscriby sends this event as one HTTP request to every endpoint subscribed to it.
