With 35 million professional members, Viadeo is one of the world’s largest professional social networking platforms. Founded in 2004, Viadeo’s network spans five continents including Asia, where membership is expanding rapidly in emerging economies such as China (Tianji.com) and India (ApnaCircle.com).

Viadeo currently has offices in Paris, London, San Francisco, Beijing, Madrid, Barcelona, Milan, Dakar, New Delhi and Mexico City. Headquartered in Paris, Viadeo has 260 employees.

The interconnection of platforms is at the heart of the next generation of social networks. Innovative developers are shaping the future of the social web by creating web applications that connect services together.

Therefore, Viadeo has recently opened up its API to developers to bring a professional social context to websites, applications and services. Viadeo gives developers quick and efficient tools for integrating with Viadeo and a means for creating independent applications.

The API uses RESTful calls and responses are formatted in XML and JSON.

Viadeo uses 3scale’s API Management infrastructure to secure and control accesses to its API, obtain insightful analytics on the usage of its API and to provide developers and partners with a friendly user environment embedding critical information such as personal statistics on their API consumption.

Viadeo will officially launch the API platform in the US and Mexico on September 7th, 2011, but developers can already access the Viadeo API platform and the technical support team. For more information, please check out http://dev.viadeo.com/.
