Duve supports manual per-reservation access codes and access codes from third-party providers which are connected to Cloudbeds (ex. Lynx, Operto etc.)
How to set it up?
Go to Settings > Custom Fields to create custom fields for Access codes in Cloudbeds
The Custom Field Name in Cloudbeds must match exactly to the Custom Field name in Duve's Connect&Sync Page
After pressing 'Save' on Connect&Sync, your access codes should start showing per room/reservation in the Unique Codes section. If needed, click 'Full Sync' and wait for the sync to be successful before checking the Unique codes per reservation.
