Frequently asked questions
When I Work scores D+ on Supergood's API Report Card. When I Work publishes a public REST API split into Primary, Login, Forecast Tools, Tasks, and Tags services, with webhooks available. The developer key comes through support rather than self-serve signup, and API tokens require an admin user's username and password.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
When I Work is a mobile-first workforce-management platform built for hourly and shift-based teams.
Vertical: Enterprise / HR / ERP, specifically the workforce-management / shift-scheduling segment for SMB and mid-market deskless workforces. Building weekly/biweekly schedules from templates and publishing to staff via push notification. Auto-scheduling shifts based on employee availability, eligibility, role, and certifications.
High inside its niche.
Employee PII (name, contact info, employment status, role, location assignment). Shift schedules, published rosters, shift swaps, drop/pickup requests, time-off requests. Time-clock punches with GPS coordinates and geofence verification.
Founded in 2010 (~15+ years old as of 2026). Cloud-native and mobile-first from inception, with iOS, Android, and web clients.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official When I Work MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. When I Work doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
