Overview

Cerrtify wraps three Swedish registries — BankID (authentication & signing), SPAR Persondata (person lookup), and Bolagsverket Company (company lookup & search) — behind a single, modern HTTP API. One API key, one base URL, sandbox and production parity.

What you get

• BankID auth, sign, phone, and payment flows — start an order, poll for status, render the rolling QR.
• SPAR person lookup by ID or name + address — XML or JSON, in sandbox and production. Production uses your own SPAR agreement with Skatteverket (details).
• Company lookup & fuzzy search — live Bolagsverket records by orgnr, plus name autocomplete over the synced register.
• Async-friendly — append ?async=true to enqueue and poll a job, or call synchronously.
• First-class sandbox — BankID and SPAR test environments with Cerrtify's test certificates, built-in test companies, no production data, no billing.
