List Canvas Pages
List pages in a canvas with dimensions and node counts.
Authorizations
API key from Settings > Developer > REST API
Headers
Calendar-dated API version pin. New integrations should pin 2026-05-01 to opt into the newest response shapes. For back-compat the server also accepts requests with no header and resolves them to the current default (today: 2026-04-12); that default advances on each sunset date. Any unsupported value returns 400 unsupported_version.
2026-04-12, 2026-05-01 "2026-05-01"
Path Parameters
Prefixed cvs_ wire ID (Crockford base32 body) — the canonical, recommended form. For back-compat, a bare UUID string is also accepted in both path parameters and JSON request bodies (older integrations that stored raw UUIDs keep working), as is the prefix over a UUID body (cvs_00000000-0000-4000-8000-000000000000). All three are permanent, supported inputs; only the canonical form is ever emitted.

Query Parameters
Optional share token (see GET /canvases/{canvas_id}).
Response
Successful Response
Display name of the canvas.
Page objects with id, name, dimensions, and element counts. Which identifier to use depends on the endpoint: the authoring and capture endpoints (markup, edit, screenshot) take the id, while the semantic-read and export endpoints (design, tokens, export) take the page_number ordinal. Prefer id where it is accepted: an ordinal renumbers when a page is deleted or reordered, so it names a different page over time. id is either a durable real page id or a session-scoped short ref (p_a) — see id_note, returned whenever short refs are present, for the short-ref lifetime; re-list to refresh rather than storing one. A page-less canvas lists one entry with no id.
Total number of pages in the canvas.
Present only when pages[].id carries session-scoped short refs: states their lifetime, and that a real id is accepted anywhere a short ref is. Absent when every id returned is already a durable real page id.
