REST API Explorer step by step guide to fetch value of catalog variables from RITM.

[Deepika Mishra]

I have a requirement to create an end point where I need to pass RITM (which will be created while submitting the Catalog Item and RITM is generated where values are captured in variables).

Please help me with step by step guide of how to implement the same as I have zero knowledge on integration.

There are many scripted REST API end-points available OOTB, you can refer any and create similar one. Open any one and read the Resources ( GET or PUT) method, this resource method has script part which manage the input, process it and return the output. 

-Thanks
