Integrační příručka: Napojení třetí strany na QHUB a příjem/odeslání Peppol dokumentů přes APEX

1. Dohodnutie SystemCode + TenantId s ASOL
         ↓
2. Odoslanie popisu entity PeppolDocument do QHUB Registration API
         ↓
3. Administrátor ASOL vygeneruje jednorazový registračný kľúč
         ↓
4. Váš systém odošle kľúč na Registration API → získa RabbitMQ credentials
         ↓
5. Nakonfigurujete RabbitMQ v svojom systéme
         ↓
6. Otestujete end-to-end komunikáciu
