Hi,
Great automation idea. You can set it up in couple of 4 steps Zaps. I have included guides.
Some comments:
Reservations made on booking engine:
Step 1 - triggers an automation for every reservation created.
Step 2 - ensures that automation works only for reservations made via booking engine (Distributor) with late check-out product included (make sure you type the exact name of your late check-out product)
Step 3 - Calculates new departure time (depending of what you are offering in my sample above it’s additional 6 hours); make sure that “To Format” and “From Format” is YYYY-MM-DDTHH:mm:ssZ
Step 4 - Update departure time, pick reservation Id from step 1 and reservation end from newly calculated dat/time in step 3
Late check-out added after reservation is made (i.e. online check-in):
Step 1 - triggers an automation for every updated reservation
Step 2 - ensures that automation works only for updated reservations with late check-out product included and departure time not updated
Step 3 and 4 - same as above
Please comment in case you have some further questions.
