Overview - Building an Application Connector Integration

A complete Connector integration follows this basic process:

1. Use the Connector Wizard to build API resources specific to your external Web application.
2. Create an integration Project containing Packages and other resources used to interact with the different APIs in the Connector Project. This would include Rulesets to create the request and understand the response, as well as read and write adapters, etc. Create Packages to contain resources specific to the operation you're performing. Examples could include an Invoice Package, Account Package, Orders Package, etc.
3. Declare a dependency from your integration Project on your Cloud Connector Project. This may also include other dependencies as well. Treat the Connector Project the same as a CORE Project - it should not be edited.  
4. Deploy the Projects to the Integration Engine, and launch the applicable Business Processes that execute an overall integration process (including those within the Connector Project that call a specific API).
