Viafo is delighted to annouce that we've added support for several of AT&T's API Services. By using the Viafo Gateway, you can now work with SMS, Location and Payment APIs with a fraction of the time and effort that working directly with the API will be.
Additionally, with the Viafo Gateway, developers don't have to hard code payment scenarios to their applications and can easily change and manage.
Keep your eyes out for more annoucements about supported carrier APIs on AT&T and other networks.
Check out the service at the Viafo Developer Site.
