AgendaBot

O Agendabot é um bot de Whatsapp que sincroniza com a agenda de Pequenos Prestadores de Serviços para simplificar o agendamento de sessões com os seus clientes. Maintained by Kamilahsantos on GitHub, where it has earned 35 stars from the community.

It's actively developed around google-calendar-api, spring-boot, spring-data-jpa, and is a solid reference for anyone building with these tools.
