Using Airbnb's API connection is always recommended over iCal due to its ability to push listing changes. In the event, where you need to use an iCal connection, use the method outlined below to ensure you have synchronized availabilities.
If you've already read the iCal Connection document, you will find the following instructions familiar. We will go into more detail about specifically sharing with your Airbnb account.
For full API instructions instead, see: Connecting the Airbnb API with Sympl
