SAPI-SK v1.0 — standard
The nationally standardised interface. The same code works with any Slovak provider implementing SAPI-SK. No vendor lock-in.
- OAuth 2.0, request body is a JSON envelope (payload = UBL XML)
- Idempotency required on every send
- 8 endpoints, 19 error codes
Enterprise API — platform
Our extended interface. Everything SAPI does, plus what the standard leaves out — events, PDF rendering, credit, archive search.
- Webhooks signed with HMAC-SHA256
- four event types, e-mail and webhook
- PDF rendering and full-text archive search
