Mule 4: Dynamically Call Multiple Subflows With One Flow-Ref

In this tutorial, we will see how to call multiple subflows dynamically with the help of a single flow reference component. 

As a first step, let's create a new Mule project using Anypoint Studio. After creating the project, we need to have all the subflow details listed under .properties/.yaml file.

Let's create a flow with HTTP Listener connector.

As a next step, let's assume we will get an attribute (header) as 'flowType' in our request. We will set a variable with a condition based on the header to route multiple subflows dynamically.

In the next step, we will add a Flow-Reference calling various subflows dynamically based on applied conditions.

In the final step, let's create different subflows as follows:

We can test the service after deploying the application in Anypoint Studio. You can use Postman/any other REST client to test the service.

The response will come back as follows (based on header that you send in your request)

I hope this article helps you understand how to call multiple subflows dynamically with the help of a single Flow-Reference.
