Set up a system to transfer data from Bitrix24 forms to javascript and vice versa

Hi, I am using Bitrix24 CRM forms and JavaScript-based forms for some web work I am doing and I need to be able to have data pre-populated into forms from javascript and data from Bitrix24 contacts and deals.

Bitrix24 has an open API that you can work with but that's a little beyond my coding skill.

What I want is a working example of the code needed to send Bitrix CRM data to javascript and a working example of the code needed to send javascript variable data into Bitrix24 CRM Forms fields with lots of notes on how to re-purpose it myself for many future projects I have I want to do in the future.

Or alternately show me how to code from my forms to send data to Bitrix24 clients and deals database and to retrieve data from those to use in JavaScript (and/orJQuery). I can build forms and do basic programming in JS/HTML and a little JQuery (am a 2nd year computer science student).

So it's a little coding and a little teaching.

I am broke because of Covid-19 so I don't have a lot to spend but I suspect it will be a very quick and easy job for someone who knows how to to this kind of work.

Thank you,

Larry
