Is there a Google Voice API? [closed]

No, there is no API for Google Voice announced as of 2021.

"pygooglevoice" can perform most of the voice functions from Python. It can send SMS. I've developed code to receive SMS messages, but the overhead is excessive given the current Google Voice interface. Each poll returns over 100K of content, so you'd use a quarter-gigabyte a day just polling every 30 seconds. There's a discussion on Google Code about this.

There is a C# Google Voice API... there is limited documentation, however the download has an application that 'works' using the API that is included:

https://sourceforge.net/projects/gvoicedotnet/

Well... These are PHP. There is an sms one from google here.

And github has one here.

Another sms one is here. However, this one has a lot more code, so it may take up more space.

I looked for a C/C++ API for Google Voice for quite a while and never found anything close (the closest was a C# API). Since I really needed it, I decided to just write one myself:

I hope others find it useful. Feedback and suggestions welcome.

Be nice if there was a Javascript API version. That way can integrate w/ other AJAX apps or browser extensions/gadgets/widgets.

Right now, current APIs restrict to web app technologies that support Java, .NET, or Python, more for server side, unless may use Google Web Toolkit to translate Java code to Javascript.
