Can api invoke other api in the same proxy ?

[pimonnat]

For example:

I have created proxy Test with base path /test/v0 and it contain 2 api A  and B.

The flow I expected is

When client call apiA -> apiA invoke apiB and do some process -> apiB response to apiA -> apiA response to client.

It is possible to implement? Please give me some advice.

Thank you
