Acall

Acall Inc. (アコール株式会社) is a Japanese workplace-experience software company, founded in 2010 and headquartered in Tokyo with a Kobe office, whose Acall / WorkstyleOS platform runs the physical side of hybrid work for more than 7,000 organizations. The product is a set of check-in surfaces — Acall Reception (iPad visitor reception and entry/exit records), Acall Meeting (meeting-room booking and utilization), Acall Desktop (free-address desk and workspace "spot" reservation / hoteling), Acall Gate (entry-gate integration), AI Meeting, Neat device integration and a multi-tenant building mode — stitched to Microsoft 365 and Google Calendar, Teams/Slack/Chatwork notifications, and SSO/SCIM-style provisioning. Acall publishes a REST "Acall Public API" (v1, bearer token) covering workers, facilities, events, gate access logs, spots and spot reservations, plus an outbound Webhook surface for appointment and internal-meeting events. API access is not self-serve: a token is issued only after a request through the contact form, and the API is unavailable on the multi-tenant plan.

Acall publishes 1 API on the APIs.io network: Public API. Tagged areas include Workplace Management, Visitor Management, Meeting Room Booking, Desk Booking, and Hybrid Work.

The Acall catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Acall’s developer surface includes authentication, documentation, API reference, support, pricing, changelog, engineering blog, and 22 more developer resources.
