How to send multi-dimensional array with "API by Pabbly"

Hello,

I am working on this automation:
https://connect.pabbly.com/workflow/mapping/IjM0MDQ4OSI_3D

I need to send a multidimensional array to Vendus Api, and I am using "API by Pabbly" integration.

Here is an example of what PHP Array Vendus API is expecting:

> see example for the Create (POST) call explanation.

My question to you is:

How can I pass the multi-dimensional array values?

E.g. 2-dimensions for "client"

Also 3-dimensions array for "payments" and "items"?

How shall I write these values in the "Set Parameters" fields?

Thank you very much for your help in advance.
