If you're like me, and STILL trying to get through the queue to schedule a COVID vaccine appointment through the overcrowded websites, you might find this Power Apps concept useful.
Using Power BI, Data Alerts, and Power Automate, I set up a flow to email me and a few family members as soon as any nearby CVS locations show availability. I was tired of clicking the website endlessly, and trying to navigate their horrific user interface. Now I can go outside today instead, and let these Power Apps do the work for me.
This entire thing framework took about an hour to set up, and demonstrates the power of Microsoft's low-code vision.
The data refreshes every 15-30 minutes, until or when I get throttled by either Microsoft (less likely) or CVS (more likely).
