Called with an editor session, only a canvas whose widgets were all made for the session's managed user can be deleted; one that also holds somebody else's widgets is refused with 409 and `CANVAS_HAS_OTHER_WIDGETS`, and nothing is deleted. Delete such a canvas with your API key. ## OpenAPI ````yaml /openapi/widgetic-api-public.json delete /canvases/{id} openapi: 3.0.0 info: title: Widgetic API Gateway version: 1.0.0 description: API documentation for the Widgetic API Gateway license: name: Widgetic Integration License url: https://docs.widgetic.com/resources/license servers: - url: https://api.widgetic.com/v1 description: Production server variables: env: default: production description: Environment apiUrl: default: https://api.widgetic.com description: API URL apiVersion: default: /v1 description: API Version path prefix security: [] tags: [] paths: /canvases/{id}: delete: tags: - Canvases summary: Delete Canvas description: > Deletes a canvas together with every widget on it.
