Currently, the best way to test your donation is to make a small donation to your organization on your campaign form. Afterwards, use the refund link on your dashboard to refund your test donation. After the refund, the test donation will be removed from your donation total. Please note that there may be a small Stripe fee associated with refunds.
Currently, it is not possible to use Stripe's test card details with Donorbox.org to send test donations. This can only be done on our demo test site.
Our development team is working on a test mode so that you can test your donations and receipt email on Donorbox.org itself, without using a real card.
