description: >-
  Squarespace authorizes third-party applications (Squarespace Extensions) with OAuth 2.0
  authorization code grant. The scope parameter on the authorize endpoint takes a COMMA-separated
  list of permission values — not the space-separated list RFC 6749 describes — and the
  confirmation page always presents the merchant's website(s) for selection because every scope is
  rooted at `website.*`. The scope list below is transcribed verbatim from the provider's OAuth
  guide. Note that the published OpenAPI declares only a single `http bearer` security scheme and
  no `oauth2` scheme, so these scopes exist ONLY in prose documentation and cannot be derived from
  the machine-readable contract — `derive-oauth-scopes.py` finds zero.
flow: authorization_code
grant_types:
  - authorization_code
  - refresh_token
endpoints:
  authorization: https://login.squarespace.com/api/1/login/oauth/provider/authorize
  token: https://login.squarespace.com/api/1/login/oauth/provider/tokens
  registration: https://developers.squarespace.com/oauth
scope_delimiter: ','
scope_delimiter_note: >-
  Squarespace documents "comma-separated list of client permission values", e.g.
  scope=website.inventory,website.orders. This deviates from the space-delimited convention in
  RFC 6749 §3.3 and is a common integration failure.
token_lifetimes:
  access_token: 30m
  refresh_token: long-term (requires access_type=offline)
  authorization_code: 2m, single use
long_term_access:
  parameter: access_type=offline
  note: >-
    Omit access_type for short-term API access. Use offline to receive a refresh token for
    long-term access; subsequent token requests use grant_type=refresh_token.

  parameter: state
  required: true
  note: Squarespace requires state and documents verifying it on the redirect URI to prevent CSRF.

api_key_permissions:
  note: >-
    API keys are a separate authorization path from OAuth and use permission LEVELS selected in the
    Squarespace admin (Settings > Advanced > Developer API Keys), not scope strings. Permissions on
    an issued key or token can never be modified — a new key must be generated, and OAuth clients
    must have the merchant re-initiate the connection.

  apis:
    - api: Forms
      levels: [read]
      note: For Zapier integration only.
    - api: Inventory
      levels: [read, read-write]
    - api: Orders
      levels: [read, read-write]
    - api: Products
      levels: [read, read-write]
    - api: Contacts
      levels: [read, read-write]
      note: API key support added 2026-06-17; previously OAuth only.
    - api: Discounts
      levels: [read, read-write]
    - api: Webhook Subscriptions
      levels: [read-write]
      note: OAuth only — no API key path.
    - api: Profiles
      levels: [read]
      note: Maintenance mode; new integrations should use Contacts.
    - api: Transactions
      levels: [read]
gaps:
  - The published OpenAPI declares no oauth2 securityScheme, so scopes are not machine-readable.
  - >-
    No scope is documented for the Webhook Subscriptions API even though it is OAuth-only; the docs
    describe the permission by name but do not publish a website.* scope string for it.
  - No scope is published for the Analytics API surfaced in the OpenAPI (POST /v1/analytics/transaction-summaries).
