Configure C4C linking objects
External Account
An external account links an account in Planon ProCenter to an account in the third-party reservation management system. The account of the third-party reservation management system will be linked through an account identifier, which depends on the related C4C app (e.g. the C4C app for a Microsoft Graph API requires an account identifier to be the email address of an user in Exchange).
External Reservation Unit
An external reservation unit links a reservation unit in Planon ProCenter to a resource in the third-party reservation management system. The resource of the third-party reservation management system will be linked through a resource identifier, which depends on the related C4C app (e.g. the C4C app for Microsoft Graph API requires the resource identifier to be the email address of the resource in Exchange).
External Reservation / Non-Bookable Period
An external reservation links a reservation in Planon ProCenter to an event in the Calendar of the corresponding resource in the third-party reservation management system, whereas an external non-bookable period links a (virtual) occurrence of a non-bookable period to an event in the calendar of the corresponding resource.
