Before we get started we need to have all connections ready for use in our orchestration. As we mentioned we are going to reuse some already existing connections, but we also have some new connections that we are going to use. The new connections include Trello and an updated version of the FlightAirlineREST API (used in Chapter 2, Integrating Our First Two Applications) which we need to set up.

For Trello, we are using another OOTB Cloud adapter. With this cloud adapter it is possible to, for example, retrieve a list of all tasks, update a task list, and create new tasks. Depending on the operation you choose you get a different response. Within the orchestration we are free to use it elsewhere in the process. For the Flight API, we are reusing the already existing connection, but we will update the API definition in apiary to include a new resource to have airline details include social preferences.
