There is no API available for creating users.2. Regarding the 'ValidateAccountHolderStatus' API, where can I find the 'accountHolderIdType' and 'accountHolderId'?3. If a user is not registered and calls the 'GetBasicUserInfo' API, what error will be received? This is not specified in the API document.4. Will the 'RequesttoPay' API function in a way where, for example, the amount will be debited from the consumer (Payer) and credited to the Merchant's wallet?5. Will the 'RequestToWithdraw' API function in a way where, for example, the amount will be debited from the Merchant's wallet and credited to the consumer (Payer)? I am looking forward to hearing from you.All the bestBenjaminCARE Denmark
