Access & accounts
eFaktúra has three integration paths, and each issues credentials in a different place. This page tells you which one is yours, before you go looking for keys in the wrong spot.
Which path is yours?
| Who you are | What you use | Where you get access |
|---|---|---|
| A company with its own system (e-shop, ERP, internal app), invoicing for yourself | REST API with a key from the app | fa.efaktura.sk → Settings → API keys (self-service) |
| A software vendor / accounting SW, integrating for multiple companies, possibly white-label | Partner Agent API | developers.efaktura.sk/register (self-service, instant) |
| A system built on the SAPI-SK standard of the Slovak Financial Administration | SAPI-SK (OAuth2 client_id/secret) | developers.efaktura.sk/register → SAPI-SK interface (self-service, instant) |
Path 1: A company with its own system
Create the API key directly in the app: fa.efaktura.sk → Settings → API keys. No approval process: you get a test and a live key immediately. API access is included in the Pro plan and above (including the trial).
App-issued keys use the efk_test_… / efk_live_… prefixes and call the same API as partner keys, so all of this documentation (invoices, webhooks, validation, error codes) applies unchanged. The only difference: where the key is issued, and that the sections about the partner portal, the contract, and live-key approval do not apply to you.
Path 2: Partner (vendor, white-label)
If you integrate eFaktúra on behalf of multiple companies (accounting software, an ERP, an agency, or white-label under your own brand), you belong in the partner developer portal (developers.efaktura.sk → Dashboard). Partner keys (efk_pk_test_… / efk_pk_live_…) can create and manage client organizations.
Registration is self-service: developers.efaktura.sk/register, e-mail and OTP, company via eFirma (IČO autofill), pick your type (API integrator / white-label) and interface (REST or SAPI-SK, optional). You get a sandbox key and SAPI-SK credentials (client_id/secret) immediately after registering, free of charge, no waiting for approval.
You request production access right in the portal, 3 steps: request production access (approved instantly for catalogue terms) → contract (e-mail code signature) → production key. You track the whole thing on the Overview, no manual e-mails with a key. Full walkthrough: Going live.
Prefer to talk to sales first (volume, pricing, white-label branding)? Write to podpora@efaktura.sk. We'll set it up manually; you end up with the same account and sandbox key, just through the sales team instead of the form.
Path 3: SAPI-SK
SAPI-SK is the standardised interface of the Slovak Financial Administration (OAuth2 client_credentials). The client ID and secret are issued in the same registration form as path 2, just pick SAPI-SK instead of REST as the interface and you get them immediately, alongside the sandbox key. Details: the “SAPI-SK (FS standard)” section in the sidebar.
client_id/client_secret, register in the partner developer portal (developers.efaktura.sk/register). An app-issued key will not work for that.Not sure?
Write a few sentences about what you are integrating to podpora@efaktura.sk. We will point you to the right path, usually within one business day.
