If u want to create a custom cart link, that adds multiple product at once (For example if 2 products drop at the same time, and u want a link to add them both)
Use the following format
http://moonitor.tools/s/funkoatc?skus=sku1:quantity1,sku2:quantity2, ...
Example
https://moonitor.tools/s/funkoatc?skus=71863:1,59189:2,54128:3
^
This will add 1 of 71863, 2 of 59189, and 3 of 54128
