How to write code in python or javascript for validating input

I need to impement one action called send_mms where user can enter list of media_url and i have to calculate url size, type if it is valid url.. I have not seen any docs related to validate input. In integration guide for developer there is one way to write code in in json format . Is there any other way where can i wirte code for above such things.

Hey @Deependra Kumar Gupta,

Internally in the Pabbly Connect developer platform, it is not possible to do validate input. You are required to provide a JSON body in correct format as required by the API.

Let me know if you any futher questions.
