Your paths from Comarch ERP to Peppol

3. API — call the REST API (OAuth2, webhooks) from custom automations for fully hands-off flows.
4. CSV / Excel — export documents and upload them in the portal; received invoices export back for import. Zero setup.

Comarch Optima/XL integrate via exports or API, with KSeF bridging for domestic invoices.

Whichever path you start with, the same account covers all of them — begin with the zero-setup option today and automate later without re-onboarding.
