The IFTTT site has a GTalk channel.
Is that the same as Hangouts?
In the GMail web page, we only have Hangouts, not chat.

It's true that IFTTT's GTalk channel doesn't work with Hangouts, but I found a similar service, Zapier, that does.
It's geared more towards business users, so the connected services include more service apps and less social media, and the free version is limited to 5 recepies (or Zaps), but it's something.
