How to send a query parameter when creating an API that consumes an API that takes a query parameter in WSO2 Integration Studio?

At WSO2 Integration Studio, I want to create an API that takes the query parameter from outside.

In the API I will create, I have an API that takes query parameters in the same way. How can I send this query parameter, to the API I'm going to consume?

Here is how you can extract aincoming Query param and add it to the outgoing request.

#Incoming Request
http://localhost:8290/currency?name=123456

#Outgoing Request
https://jsonplaceholder.typicode.com/todos?id=123456
