This recipe demonstrates how you can use one integration flow to invoke another non-local integration flow. For this purpose, the recipe’s integration flow invokes the integration flow of the REST — Oracle Integration | Send a Hello Message recipe.

The recipe contains an application-driven integration flow, which uses the standard REST Adapter.

To use the recipe, you must install the recipe and configure the connections within it. Subsequently, you can activate the integration flow of the recipe and send a GET request (containing a name and email address) to the integration flow’s endpoint URL from an external application. When triggered, the integration flow invokes a child flow (through another REST Adapter) and passes on the payload details. In turn, the child integration flow sends a sample message to the email address specified in the request parameter. A response is returned to the external application.
