These accounts simulate real-world conditions, allowing you to explore the API’s features and validate your payment workflows before going live. You can request access to a sandbox account by signing up [here](https://www.blinkpayment.co.uk/developer-signup). By default, sandbox accounts come pre-configured for card payments. If you wish to test Direct Debit transactions, you can do so by connecting to a GoCardless sandbox account through our platform. Currently, only GBP transactions are supported within the sandbox environment, but additional currencies can be enabled upon request. ## Key Features - **Card Payments**: Fully functional out-of-the-box for testing. - **Direct Debit Support**: Available by linking a GoCardless sandbox account. - **Open Banking:** Fully functioning Open Banking simulator that mimics real-life bank payment flows. - **Currency Support**: GBP is the default currency, with other currencies available on request. ## Limitations - **Google Pay and Apple Pay**: These may not function within the sandbox environment. - **Test Cards and Limits**: Specific test cards and transaction limits apply.
