I just put together this API in PHP for retrieving the online status of a Google Talk user. It’s based on the Google Talk badge but allows for server-side access to a user’s status.
Why would someone need such a thing? Well, let’s say they wanted to create a badge controller which checks a number of users to see if they’re online, and when it finds one, it displays the badge for that user. This controller can then serve as a live help module to place on a web site to allow site visitors to talk with any available representative. If no rep is available, the controller can disappear seamlessly, or display a link to a contact form or help/faqs pages.
Download gtalkStatus.class.php
Download checkSkype.class.php, a modified phpclasses file for checking a Skype user’s status. Skype is, to date, much more friendly for allowing APIs to access a user’s status.

* 2- To create your chatback badge, visit http://www.google.com/talk/service/badge/New. If you’re using a Google Apps account, you can create a chatback badge by visiting http://www.google.com/talk/service/a/DOMAIN/badge/New where DOMAIN is the name of your domain.
* 3- Use the alphanumeric account hash to seed the constructor
Thanks for posting this. It was easy to use and worked great. I used it for a Flash piece here . Do you know if there is any way to set your Google Talk status remotely? I’m looking for a way to update my status “busy” or “available” without using GMail or GTalk. Any ideas?
Keep up the good work,
Adam
You can check out http://code.google.com/p/xmpphp/
You should be able to connect to the Google server and set your “presence”. Not sure if this will cause a collision if you have a session open on another client, but try it out.
My website wants to generate google chatback badge code for the user instead of user going to the google chatback website and copying paste to my site.

I don’t know about any API to do this. Sorry
Is there a way to get Gtalk Friend’s Status as Feed
Again, I don’t have much experience, but check out the XMPPHP project. Should be able to do it.
I want to show gmail user status in my web page only i have gmail user ID nothing else how can do that
If you’re looking to simply show your status in your web page, you can use the Badge generated by Google by visiting the Google Talk badge page, and following the instructions there.
Hi,
Is it okey if I use your script in a WordPress plugin? And can I credit you if I upload it to WordPress.com plugin repository?
Best regards

Sure Victor. I expect the settings page will include a link to the badge-generation page, and make the config easy. (Read the class comments for more info)
What’s the complete functionality of the plugin? Something like the scenario I described in this article?
Hi Israelwebdev,
The plugin should have similar functionality as another WordPress plugin using your script – Google Talk Chatback Widget (http://wordpress.org/extend/plugins/google-talk-chatback-wordpress-widget/).
The goal is to make it more customizable and easier to use. Besides support for WordPress widgets you will also be able to use shortcodes or template tags.
