Before I investigate what features they want and how to implement, can someone let me know if this app is going to continue to be updated with all the changes at Salesforce? And if I were to install it now, with the api upgrade messages that I am seeing, is it safe to do so?
Ah ok yes, I see that on your company's website. Well, what are you looking for in a new fundraising software? The correct option depends on your company's individual needs.
Popular option include Donorbox and Form Assembly. These options would allow you to embed it on your website, rather than a separate web page; have an integration with Salesforce; and give donors the option to make recurring donations.
