  title: Nowsta Integration Venues API
  version: 1.0.0
  description: "The Nowsta Integration API lets an approved partner platform publish event, shift and position data\ninto Nowsta, along with the supporting system inputs — venues, clients, uniforms and workers — that\nenrich that data.\n\nThe API is deliberately narrow: every resource is exposed through a single bulk \"publications\"\nendpoint that accepts an array of objects and performs create-or-update by the caller's own external\n`id`. There are no read (GET), PATCH or DELETE operations in the public integration surface.\n\nSemantics published by Nowsta and preserved here:\n\n* Every publication is a **POST, not a PATCH** — omitted fields are reset to their default (`null`),\n  so callers must send the complete object on every update.\n* Every successful publication returns **202 Accepted** with the id of the queued job; Nowsta cannot\n  guarantee a request is honoured on receipt (for example it will not remove shifts or shift slots\n  that would unassign already-scheduled staff without coordinator confirmation).\n* Batches are limited to **32 items**; larger batches are rejected with 422 / error code 1203.\n* Publication requests for the same company are **queued and processed serially**, so callers are\n  advised to issue requests in series rather than in parallel.\n* Access is **allow-listed**: Nowsta must approve a company before its token works, otherwise\n  requests return 403 with error code 1101.\n\nDERIVATION NOTE — this document was transcribed by API Evangelist from Nowsta's own published\nIntegration API reference (the Slate-generated site formerly at https://developer.nowsta.com/,\ncaptured at https://web.archive.org/web/20240603053309/https://developer.nowsta.com/). Every path,\nmethod, field name, type, nullability, constraint, status code and error code below appears verbatim\nin that reference. Nowsta does not publish a machine-readable specification; nothing here was\ninvented. The live production API was probed on 2026-08-01 and confirmed to still serve these paths\n(unauthenticated POST returns `401 {\"errors\":[{\"code\":1000,\"message\":\"Nil JSON web token\"}]}`)."

      summary: Publish venues
      description: Bulk create or update venues on Nowsta, matched on the caller's own `id`. Venue names carry a uniqueness constraint in Nowsta, so a submitted name that collides with an existing one will be altered by Nowsta to preserve uniqueness — which is one reason the response is 202 rather than 200. Omitted fields are reset to `null`.

    Accepted:
      description: Accepted and queued. Nowsta returns 202 because it cannot always guarantee that an update will be honoured on receipt — in particular it will not remove shifts or shift slots that would unassign staff without coordinator confirmation, and colliding venue/client/uniform/position names are altered to preserve uniqueness. The body carries the id of the queued job.

      description: 'A per-company integration token issued by Nowsta and retrieved by the customer from the Nowsta UI, then entered into the integrating platform (for example on a settings page). The token is scoped to the single company that purchased the integration and only authorizes operations for that company. Send it as `Authorization: Bearer <token>`. HTTPS is required; cross-origin browser requests are not permitted. Nowsta must first approve a company for the integration — requests on behalf of an unapproved company return 403 with error code 1101.'
