Using REST with Flow Director
Integration with Ease.
Representational state transfer (REST) is a software architectural style that defines a set of constraints to be used for creating web services. Flow Director provides a REST API to make any flow a RESTful web service. It provides a REST client to access any web service from within a flow.

This example shows the sending of a monthly newsletter. It starts with a timer that sends a timer event each month. Since all flow component connectors are typed, the timer event must be converted into a normal message that the query component accepts. The query component is connected to a customer database and selects all customers who are subscribed to the newsletter. Each selected customer is passed to a Send Newsletter component that calls the REST API of SendGrid, a mailing service.
