Guesty has an Open API that Boom can connect to to pull property and reservation data directly from Guesty.
Steps to connect Guesty to Boom:
This article from Guesty explains how to create a unique API key for Boom. Scroll down to the "Create API key pair" section.
Copy your "client ID" and "client secret" key and keep them somewhere safe.
In Boom, go to Main Menu>>Configuration>>Settings>>Integrations, scroll or search for the Guesty tile. Click "Settings"
Enter the client_id and client_secret you saved from Guesty, then click CONNECT, then SYNC NOW.
Boom should now start syncing with your Guesty account. This may take up to 12 hours based on the Guesty API traffic.
