Ask HN: Connecting to multiple APIs through a single interface?

I'm looking for a service like Zapier, but more consumer oriented. I want to integrate into a single interface and allow my customers to push content to FB, Twitter, Google Cal, Docs, Sheets, Email, etc. Is there anything like this out there? As far as I can tell IFTTT could work, but not like I want. I'd need to create an Applet that the user would access through IFTTT, rather than handling the integrations inside my app.

Worst comes to worst, I'll build out integrations for each service I want--but that seems like a lot of work and is likely duplicative. Thanks in advance.
