We are developing a website for a charity trust in India. For this we need to add a "donate" button to the website for anyone who wants to donate to the charity through a payment gateway.
However, both Paypal and Google Wallet / Google Checkout restrict the use of the "donate" button in India (Google, rather than a donate button, provide a "support" button).
Are either of these payment gateways possible to integrate into a website in India? Or are there any other alternatives?
