Keyper

keyper is an Austrian technology company providing connected ticketing and digital access solutions. Its developer platform lets ticketing systems, resellers and access control systems (ACS) deliver e-tickets and exchange access data through the keyper Access API, Connect Provider / Reseller APIs, Ticket Delivery API, native Android and iOS SDKs, and embeddable web components (seatmaps and checkout). The Access API sends entry transactions for keys (ticket barcodes) and their permissions (events), and returns the Grant / Block permission whitelist an access control system enforces at the gate. keyper serves sports, arts and culture organisations across Austria and Central Europe and is backed by Speedinvest.

Keyper publishes 2 APIs on the APIs.io network: Permissions API and Transactions API. Tagged areas include Company, Ticketing, Access Control, Event, and Developer Platform.

Keyper’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, sandbox, and 16 more developer resources.
