That I do not know. I do not use IFTTT but if you go through the following thread on blink cams, they discuss the IFTTT option in detail after blink discontinued the integration with ST and moved to IFTTT applets. I assume there are some similarities between the two products but at least it gets you on the right path. Go to the bottom portion of that thread.
Or hopefully someone can chime in and offer more assistance than I can provide.
