With the removal of Alexa integration with IFTTT, it had myself along with many others wondering what to do to keep Alexa’s reminders synced with the iOS shared reminders list (which we use constantly for grocery / shopping).
I did some playing around with the Alexa documentation and ended up finding out I could access the Alexa list via their API using a login credential in Scriptable’s web view / request APIs.
The code can be found on my GitHub page here along with some additional instructions on setup.
