FellowshipOne has an application programming interface (API) that allows churches and business partners to easily extend the power of the software. The FellowshipOne API is built upon REST application architecture principles and is free to use by churches using FellowshipOne and qualified business partners.
A community site is available at Developer.FellowshipOne.com that includes all of the details you need to begin building add-ons or integrating a 3rd party application to FellowshipOne. The site includes source code for example applications for the iPhone, Facebook, ExpressionEngine, and Microsoft MVC. We are excited to see all of the creative things that the community of developers will build for the Church with this API.
Extend the power of FellowshipOne with our API and developer tools. To learn more and apply for a key to use the Fellowship One API, please visit Developer.FellowshipOne.com today! Stay connected by following the FellowshipOne Development team on Twitter: @F1Dev
