In OutSystems Forge, there are a number of connectors to the most popular cloud services, like Facebook, Twitter, Zendesk, and Twilio. Some of these connectors come with a sample app so developer can try it out. Because the OutSystems Platform IDE is integrated with Forge, so it's easy to download and start customizing connectors.
Most of these components are built with OutSystems Platform, using the SOAP web services and REST APIs provided by these popular cloud services. Some of the components also use standard C# or Java. These components can get developers started quickly, but it is also possible for a team of developers to use OutSystems Platform to create their own.
The following list is just a sample of what is available; more components and connectors are added all the time to the Forge.
