Testing Refunds and Withdrawals in Sandbox

Once you create a Payment Intent in sandbox environment, you can set it to the desired state directly on the Payment Window UI or by making an API call to one of the available Test API endpoints.

It is recommended to choose USDC on Ethereum when testing Refunds and Withdrawals in Sandbox. This way the refund for a Payment Intent or a withdrawal that you execute will be completed in sandbox, relevant callback will be sent to your webhook URL, and you'll receive the refunded amount of USDC on Sepolia testnet.

To receive USDC on Sepolia testnet, simply add the token to you wallet using the following details:
