Connect Illizeo to your identity provider, signature solution, calendar and in-house tools.
Fully configurable OAuth 2.0 (endpoints, scopes, client_id, client_secret, callback_uri). Native Google and LinkedIn social SSO. Per-role TOTP 2FA via Google Authenticator.
DocuSign and Adobe Sign natively integrated. Connect your existing account via OAuth, use your current credits, signature statuses sync back into Illizeo automatically.
Personal tokens with expiration date, rate limiting, usage statistics and individual revocation. Every API call is logged (endpoint, IP, duration, HTTP status).
CSV, XLSX, PDF for business exports (headcount, positions, pay grades, work orders…). iCal feed to sync absences with Google Calendar, Outlook or Apple Calendar.
Optical receipt reading via Tesseract (FR + EN), automatic extraction of merchant, amount, date and category. Receipts never leave the browser on the client side.
Event-driven webhooks (signature, approval, payroll closed) and sandbox environment for integration testing. Available on request for Enterprise accounts.
Issue a token per user, per use case or per environment. Define expiration, permissions, rate limit. Track calls in real time: who, from where, on which endpoint, in how much time.

Basic workflow without legal value
All communications with the Illizeo API are encrypted in TLS 1.3. Authentication tokens are stored and transmitted securely. Swiss hosting, ISO 27001 certified, GDPR and Swiss DPA compliant.
Four integration principles competitors prefer to forget.
Documented REST API, named tokens, standard formats. You stay in control of your integrations.
CSV, XLSX, PDF, iCal — your data leaves in the format you choose, whenever you choose.
Plug in your existing DocuSign or Adobe Sign via OAuth. Your current credits are used, no surcharge.
Standard OAuth 2.0, fully configurable end to end. Compatible with your existing identity provider.
Via the secure REST API. Generate a token with the right permissions and call the endpoints from your middleware. For recurring needs (Sage, Cegid, etc.), our team can help you build custom connectors.
Fully configurable OAuth 2.0 (Auth0, Okta, Microsoft Entra ID, Keycloak, Google Workspace, and any standard OIDC provider). Native Google and LinkedIn social SSO too.
Event-driven webhooks (signature, approval, payroll closed, etc.) are available on request for Enterprise accounts. Public roll-out is in progress.
From Settings → API Tokens. Provide a name, expiration date, permissions and rate limit. The token is shown only once — copy it to your secret vault.
Configurable per token. Default: 60 req/minute and 50,000 req/month on the standard plan. Beyond that the API returns 429. Enterprise accounts can negotiate higher limits.
On our developer portal: developer.illizeo.com. You’ll find full endpoint documentation, request examples, webhooks and a sandbox environment.
Yes, TLS 1.3 on 100% of communications. Tokens are never stored in clear on Illizeo’s side (hash + salt). All calls are audited in real time.
