Frequently Asked Questions
Data is never stored on our servers; instead, we route requests directly to the external service, preserving security standards and encryption. Candle’s SDK works just like the official app or website does.
Our SDK currently supports financial services like Robinhood, Cash App, Venmo, Apple Wallet, and more. Our grand vision is to be the only SDK you’ll need to connect to any service. If you need support for a specific one, let us know or with us.
