From an article, a heads up for user of IFTTT:

IFTTT in a blog post said that Amazon is removing the service from Alexa beginning October 31st. "Once the integration is severed, users won't be able to ask Alexa to trigger IFTTT applets," reports The Verge. "Certain automations will stick around in the IFTTT app, but some will be archived on November 1st unless you take action." From the report:

If your IFTTT applets use a specific phrase or question as the trigger ("Alexa, trigger..." or "Alexa, what's on my to-do list?"), that will convert to using an IFTTT button widget that you can either use in the app or add to your smartphone's homescreen.

But all other triggers set up through Alexa -- say, an automation that runs when you add something to your to-do list -- will be archived. You will also have to remove any Alexa ingredients from your applets or they'll stop working.

IFTTT suggests a few alternatives to pursue to keep using it. In addition to button widgets, users can try Apple Shortcuts or the IFTTT note widget. It's also still integrated with Google Assistant, though voice commands have to start with "activate" before an applet will trigger.
