Read on adding funding accounts for users.
In order to be able to send money, the user will have to link a funding source. Currently, we support payment using bank accounts and debit cards. All bank accounts and debit cards need to be added using Machnet's widget in order to remain compliant. However, specific details of the funding account can be obtained through an API. The response can be stored on your end for further operations such as Create Transaction, etc.
Receive users may also have an account associated with them to receive the funds. There are specific endpoints to add receive accounts for a receive user.
