Can I use IFTTT as a webhook to update my website after a booking on an OTA like AirBnB?
YES If an OTA sends you confirmation emails after a booking, IFTTT.com can use that mail to make a web request to a publicly accessible URL (webhook). And the good news is.... the Room Booking plugin already has this webhook available (we use it for our cronjob)!
PLEASE NOTE While this will update the availability on your website almost instantly, other OTA's will only be updated at the interval that they have set for themselves. This is out of our control as these other OTA's will probably not have a webhook that you can request.
