3. Funding source and payee creation

Background to funding source and payees

An external funding source (e.g. direct debit to pull money) and payees (e.g. external bank account to pay money to) can be assigned to a wallet.

These first need to be created and the Customate platform validates these details to ensure funds can be pulled from the funding source and paid to a wallet or funds can be pushed from the wallet to a Payee. Therefore it is important that these details are correct and validated.

Below are tables of test data and associated errors, that can be used to simulate various problems during Direct Debit funding source or payees creation.
