Chrome extension tool for Kickstarter

I need to write a program that will help calculate ROI from Facebook ads leading to a Kickstarter project. PROBLEM: The problem is that it is not possible to install a Facebook Pixel in a Kickstarter project, though it is possible to install a Google Analytics UA code. Almost anyone who runs a Kickstarter campaign has Facebook ads leading to their campaign, but because there's no Facebook Pixel on the campaign page, you can't see the price per conversion on the Facebook platform. The way to deal with it at the moment is to cross-reference data from Facebook and Google Analytics: You see how much you spent on a specific campaign on Facebook, and then go to Google Analytics and see how many purchases/revenue came from that specific campaign. That way, you can calculate ROI on your campaigns. However, it's slow and complicated. SOLUTION: For the solution, I need a tool that will connect to: a. Facebook Ads account b. Google Analytics account --> property --> view c. Kickstarter campaign -> I need the tool to automatically cross reference the data from Facebook and Google Analytics and tell me the ROI for every campaign I'm running for a Kickstarter campaign. -> I would like the tool to be a chrome extension that I can install on my browser -> I would like to be able to choose through the tool which Facebook ads account and Google Analytics account I connect to
