Functions for post only scheduling

Hi all,

I am working on creating a scheduling system for my delivery dry cleaning company. What needs to happen is people choose a day and time slot when they want their cleaning picked up (Mon-sat, 9am-11am, 1pm-3pm, or 5pm-8pm). The app would then need to generate a list of all the users at each time slot.

There doesn’t need to be any availability check, specific time scheduling, or anything fancy.

Can this be done in bubble itself, or would an external API (such as timekit.io) be required?

Thank for any tips!
