Hello, I am a developer developing a donations platform for a fund. The fund, by themselves, is creating multiple projects for fundrising that will be posted on the website. On the website, they want to have integration with PayPal to be able for users to donate to a chosen project. After the donation payment has been completed, the "Funds raised" number would update accordingly to the sum the user donated (similar to the eCommerce shop, but without products). Is it possible with PayPal API and what API should I use?
Should note that donations fund is legally registered in Ukraine and operates in Ukraine.
