Hey Api Platform Webhooks

asyncapi_published: false
asyncapi_note: >-
  Hey API publishes NO AsyncAPI document. Probed /asyncapi.yaml and
  /asyncapi.json on heyapi.dev and api.heyapi.dev (404), and the GitHub org
  carries no event spec. This artifact is the webhook catalog derived from the
  provider's own OpenAPI — it is deliberately NOT dressed up as an AsyncAPI
  document, because Hey API did not author one.

api: Hey API Platform API
description: >-
  Project-scoped outbound webhooks. A project owner registers an HTTPS
  endpoint; Hey API POSTs a signed event to it when a specification is created
  or deleted. This is what makes the registry reactive — a downstream repo can
  regenerate its client the moment a new spec lands.

subscription_management:
  create: POST /v1/organizations/{organization_slug}/projects/{project_slug}/webhooks
  create_body: '{ "endpoint": "https://example.com/api/webhooks" }'
  list: GET /v1/organizations/{organization_slug}/projects/{project_slug}/webhooks
  read: GET /v1/organizations/{organization_slug}/projects/{project_slug}/webhooks/{webhook_id}
  update: POST /v1/organizations/{organization_slug}/projects/{project_slug}/webhooks/{webhook_id}
  delete: DELETE /v1/organizations/{organization_slug}/projects/{project_slug}/webhooks/{webhook_id}
  auth: Clerk session JWT
  enable_flag: Webhook.is_enabled (boolean)

signing:
  secret_field: Webhook.secret
  secret_prefix: whsec_
  disclosure: >-
    The secret is only present on the `Webhook` schema returned at creation.
    Every listing returns `WebhookConcealed`, which omits it.
  algorithm: not documented
  signature_header: not documented
  note: >-
    A signing secret exists in the contract but the verification procedure —
    header name, hashing scheme, timestamp tolerance — is published nowhere.
    A consumer cannot currently verify a Hey API webhook from public docs.
    This is a real gap for the provider to close.

events:
  - type: specification.created
    payload: Specification
    description: >-
      A new OpenAPI document was uploaded to a project — typically by the
      hey-api/upload-openapi-spec GitHub Action on a push or pull request.
      The payload carries the full CI provenance (repository, branch,
      commit_sha, workflow, run_id, actor, tags, version).
    typical_consumer_action: regenerate the downstream SDK against the new spec
  - type: specification.deleted
    payload: Specification
    description: A stored specification was removed from the project.
