  version: 1.12.0
  description: 'The HummingDeck API. Provides document search, upload and replacement, room creation and structure (tabs, documents, links, embeds, sections), room archive and restore, document and room share link management, company/contact find-or-create operations, view and decision events, and webhooks for the Zapier integration.


    Two credential types are accepted, and they are not interchangeable:


    **Workspace API key** (`Authorization: Bearer hd_api_...`): issued by a workspace owner or admin in Workspace settings, Integrations, HummingDeck API. REST API access is available by request on Business and is enabled per workspace after review. A workspace can have multiple named keys, each with an explicit set of scopes and independent revocation. Each write scope includes the matching read scope; read scopes do not grant write access. The raw key is shown once at creation and is not retrievable afterwards; it expires one year after creation. Every key is bound permanently to its workspace, so a request cannot select or override its workspace. Webhook subscription endpoints are not available to this credential.


    **Zapier OAuth** (`Authorization: Bearer {access_token}`): issued through the OAuth authorization flow when a workspace connects the Zapier integration. Access tokens expire after 30 days; the 90-day refresh token obtains a new one. This is the only credential that can create or delete webhook subscriptions.


    Each operation documents its primary always-required workspace-key capability in `x-required-api-key-scope`. Additional always-required capabilities appear in `x-additional-required-api-key-scopes`; body-dependent capabilities appear in `x-conditional-api-key-scopes`, keyed by scope with the exact trigger as its value. `GET /me` requires no scope. A valid key that lacks a required capability receives `403 INSUFFICIENT_SCOPE`; the response names `requiredScope`.


    Manual keys and Zapier OAuth connections are limited per credential to 600 reads per 5 minutes, 120 writes per minute, 60 room-view reads per minute, and 20 uploads per hour. Shared workspace ceilings are twice those values across all credentials. Failed bearer authentication and invalid OAuth client authentication are each limited per trusted client IP to 60 attempts per 5 minutes. Requests may receive `429 RATE_LIMITED`; use the delta seconds in `Retry-After` before retrying. Rooms API JSON bodies are limited to 262,144 bytes; company, contact, share, and webhook JSON bodies are limited to 32,768 bytes; and document-upload and replacement multipart requests are limited to 32,505,856 bytes, including at most a 30 MiB file. Oversized bodies return `413 PAYLOAD_TOO_LARGE` before structured parsing.


    A request is rejected with 401 when the token is unknown or malformed, has expired, has been switched off, belongs to a workspace whose API access was turned off, or was issued by someone who is no longer an owner or admin of that workspace.'
