Hi HN. Long story short: my girlfriend is a massage therapist being
squeezed for big commissions by a marketing service (treatwell.com)
that has shut down its API for bi-directionally syncing its calendar
with hers, probably as a deliberate lock-in tactic. Treatwell reads
her google calendar to avoid clashes, but writes only to its own when
someone books through treatwell. With her clientele increasing through
independent referrals, she's investigating alternatives including
self-hosting, but assuming it's not worth ditching treatwell entirely,
what tools would you recommend for scraping her treatwell calendar to
keep her google calendar in sync?
