If you haven’t seen https://free-for.dev/# yet, i suggest checking it out… so many ways to extend and accentuate our Glide apps. I look forward to learning which available APIs you decide to tackle.
I came across Calendarific and will be trying it as an Add to Calendar experiment… Enterprise-grade Public holiday API service for over 200 countries. Free plan includes 1000 calls per month.
Have a great weekend!
