How do I make sure that Availability Blocks created in Rental Ninja are send to Rentals United?
In Rental Ninja:
Go to Rentals
View a Rental
Go to iCal Exports
Click on +New iCal Export
Give it a Name (This is an internal name. for example: RN Blocks for Rentals United)
Select the Source of the Bookings you want to export to Rentals United. This should be: Block in Rental Ninja. (When connecting to Rental Ninja through Rentals United, all Bookings of the other Sources should already be visible in Rentals United's calendar).
Click on Create
Copy the iCal export link
In Rentals United:
Paste the iCal link in the Rental's Calendar so that it will import all the Blockings from Rental Ninja.
