Can read and write into calendars. - We need to be able to set the shop's open and close time, as well as the appointments durations: 30, 60 120 mins. - We need to be able to set scheduled holidays (shop is closed) - We need to be able to set buffer times (times between 2 appointments) - Appointments are via Google Meet, so a google meet link must be created. - Similar visualization as Calendly. ----------------- EXAMPLE: ----------------- We need a module that has the same features as www.calendly.com. Please visit calendly to get know basic features we need. ---------------------------------------------- ADDITIONAL INFORMATION: ---------------------------------------------- - Hungarian language is preferred by developed, but not obligatory - Time to deliver the job: 6th February, 2022. - We can only accept tested and working code - Please provide us test version during the developing, so we can help each other - Code must be clean and guided by base comments, to help further developing by other programmers Thank you for your apply, Matthew
