title: HourSquare Public Employees API
description: 'The HourSquare public API: record clock events and completed shifts, read time entries, and list employees for one company.
**Authentication.** Create an API key in HourSquare (Settings → API & integrations; you see it once). Exchange it for an access token at `https://api.hoursquare.com/api/public/v1/oauth/token` (OAuth 2.0 client credentials: `grant_type=client_credentials`, the key as `client_secret` or as the HTTP Basic password). Send the token as `Authorization: Bearer `. **Tokens live 15 minutes** — cache one and request a new one when it expires or on a 401. Never put a key or a token in a URL.
**Scopes.** A key carries the scopes it was created with; each operation below names the one it needs (`attendance.record`, `attendance.read`, `employees.read`, …). A person''s own HourSquare token may also call the operations their permissions cover. Calling without the scope returns `403 insufficient_scope`. When fetched with a token, this document lists only the operations that token may call.
**Rate limits.** 300 requests per minute per key on these resources and 60 per minute per key on the token endpoint, sliding windows, enforced per server instance (so approximately). Every response carries `RateLimit`, `RateLimit-Policy` and `X-RateLimit-Limit` / `X-RateLimit-Remaining` / `X-RateLimit-Reset`; a `429 rate_limited` carries `Retry-After`.
**Revocation.** Revoking a key stops new tokens immediately; tokens already issued keep working until they expire, so **within 15 minutes of Revoke every request with that key fails**.
**Errors.** Every error is `application/problem+json` (RFC 9457) with a stable snake_case `error` you can branch on (`employee_not_found`, `already_clocked_in`, `no_open_session`, `session_too_long`, `overlaps_existing_entry`, `day_locked`, `validation_failed`, `idempotency_key_reused`, `time_tracking_disabled`, `insufficient_scope`, `rate_limited`, …), the numeric `code`, a human `detail`, and a `correlationId` to quote to support. `validation_failed` (422) lists the offending fields in `errors[]`.
**Idempotency.** Send an `Idempotency-Key` header (unique per request, at most 128 characters) on writes to make retries safe: the same key replays the first response. Without it, the same employee, event type and caller within 60 seconds of an existing entry returns that entry with `200` instead of a duplicate; a later retry may see `409` instead of the original `201`.
**Dry run.** `X-HourSquare-Dry-Run: true` on any write validates and resolves everything, writes nothing, and returns the would-be result with `dryRun: true` and status 200. This document declares the header with default `true`, so a try-it panel never writes unless you flip it; the server treats an absent header as a real write.
**Time zones.** `occurredAt`, `clockIn` and `clockOut` are RFC 3339 timestamps with an explicit offset. They are recorded in the employee''s workplace time zone, else the company''s; when neither is configured the wall-clock you sent is kept. The response echoes `timeZone` (an IANA id or `offset`) and the server-resolved instant.
**Versioning.** The major version is in the path (`/api/public/v1`). Within v1 only additive changes happen: new optional fields, new endpoints, new enum values (documented as "may grow"). Breaking changes get `/v2`; v1 then carries `Deprecation` and `Sunset` headers for at least six months.
**Keep it safe.** Keys and tokens never belong in a URL, a browser page or a log; rotate a key when in doubt (the old one keeps working for the grace period you choose).'
