Is there a Google Voice API? [closed]

Is there an API (officially or unofficially) for Google Voice? I would like to have an API to work with voicemails, send/receive SMS messages, initiate calls, etc.

What is the Android client using? Something internal? Has anyone documented it?

A question to ask Google. Voice is still rather in private testing and most of SO would not have an account on Google Voice. – Doane 3/11, 2009 at 16:51

You may also want to look into VoiceXML en.wikipedia.org/wiki/VoiceXML – Oberland 3/11, 2009 at 16:52

VoiceXML is not quite right, since Google Voice does almost no voice processing, just signaling and routing. – Idiophone 3/11, 2009 at 16:53

An official API is not out yet. But, if you want to experiment with other services similar to Google Voice, check out twilio.com or aws.amazon.com/sns (SMS). – Guam 6/12, 2011 at 15:26

Just a thought, there seems to be a C# Google Voice API. sourceforge.net/projects/gvoicedotnet – Exigent 10/9, 2015 at 1:14

For Java/Android there is GV4J: github.com/twyatt/gv4j – Radish 7/11, 2015 at 19:16

This is not an API, but is a Selenium nodejs script, and it works if you want to automatically send a small number of SMS messages using Google Voice: github.com/ourarash/autogvoice – Straley 4/12, 2017 at 17:35

A more maintained way to both send and receive SMS with Google Voice is to turn on emails in Voice settings and grab your data from there. – Delilahdelimit 9/1, 2019 at 22:43

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.

Christmas 2011 and no Google Voice API in sight. – Meat 26/12, 2011 at 6:41

It is 2012. No API. – Elsi 2/1, 2012 at 20:41

Alas, pygooglevoice seems relatively inactive in terms of development and is plagued by many un-addressed issues. I can't recommend it unless you are planning to hack on it yourself. – Blowing 19/2, 2012 at 22:54

Did you checkout gvoicedotnet.sourceforge.net – Button 23/2, 2012 at 10:1

Google currently offers this service free of charge. If there was an official api, it would be cost prohibitive. And it would be difficult to keep it free. There was an iPhone app that took advantage of this to offer free sms but google shut that down... same reasoning. I would guess once google starts charging for this service next year, they may release one. My 2cent. So please no more "2012. No API" comments... adds no value. – Snuck 23/2, 2012 at 18:35

@samyi There are still iPhone and Android apps out there that allow GV users to send free SMS. I think it is Apple that doesn't want its customers turning to Google for a service that they'd prefer to host (control). – Spigot 16/11, 2012 at 22:40

But text messages are carrier based. Not Apple. When IP first came out several years ago, they had an app that piggybacked on google voice for all texts and thus eliminating the need to have a text plan. Google put a stop to that app due to increase in traffic. An api would be very simple for google to release... it just doesn't make business sense. Apple wouldn't have much say in apps using google... if they could they'd probably prevent google from releasing any apps in their ecosystem but they'd blemish their "draconian" reputation even further. Not going to happen. – Snuck 19/11, 2012 at 18:31

Is it legal to use any unofficial API without a permission from Google? – Patricide 5/11, 2013 at 9:27

The old Google Voice goes away May 14, 2014. A new, more locked-down system is replacing it. No more "third party apps". – Botnick 6/12, 2013 at 3:14

@JohnNagle Does that mean that pygooglevoice will no longer work? The latest version (0.5) is broken and abandoned and it sounds like there's no point in trying to revive it. – Shallot 25/10, 2014 at 15:33

Almost 2015 here.. No API – Tilefish 18/12, 2014 at 16:36

It's 2015 and No API... oh wait, Google has been trying to incorporate voice into hangouts and it looks like hangouts DOES have an API developers.google.com/+/hangouts/api - that one mentions google voice, at least for billing account balances. This is probably the place to start and where to direct your feature requests. – Laudatory 14/1, 2015 at 17:16

Its 2998. Google has finally been defeated and Bing is on the rise. Google has finally re-vamped their Google Voice API from 2035 to compete with Bing Voice. Currently Google Voice API is down while the war of galaxies is occurring. This message was sent over a trillion Milky ways away, when you receive this, the year would be close to 9098. Good luck to the last human survivors, Mars has never been so friendly. – Varner 23/11, 2018 at 2:44

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:

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.

Marsupial answered 24/11, 2011 at 2:18 Comment(0)

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:

http://github.com/mastermind202/GoogleVoice

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

Ledger answered 25/9, 2010 at 1:35 Comment(2)

Its gone now. How did it work and where is it? – Politesse 14/7, 2016 at 1:14

There's what looks like a fork of it (judging by the "MM" for "mastermind" signature on the README and the commit dates being right before this answer's 9/25/2010 date) here: github.com/siraj/GoogleVoice . – Urge 21/4, 2021 at 21:19

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.

Tynes answered 1/11, 2010 at 4:56 Comment(3)

Duh, great idea, now for someone to do so. I may try when I have time, not anytime soon. But a JS port may be restricted by XmlHttpRequest limitations within browser. So it will still work best in other unrestricted JS environments like node.js, Windows Scripting Host, Rhino engine, and browser extensions/add-ons/widgets. – Tynes 1/2, 2012 at 8:25

Done. I am the author of github.com/amper5and/node-google-voice. – Inellineloquent 8/4, 2012 at 7:1

thanks ampersand, I'll check out this JS implementation sometime. – Tynes 23/6, 2012 at 7:46

I needed a C# API and after spending hours looking for it (all I found was outdated and non-working) and unsuccessfully trying to port the PHP/Python/Java versions listed here (none worked either) I decided to create my own. It's SMS-only for now...
