What is the difference between the balances returned?

It shows the balance that is available for spending to the end-user. This balance reflects the balance and includes any pending transactions* and overdraft.

It shows the balance after all payments that have been processed. This will not include any pending transactions, which is why end-users may see a discrepancy between their 'Available' and 'Current' balances.

Example:

{
"results":
{
"currency": "GBP",
"available": 1161.2,
"current": 1170.2,
"overdraft": 1000,
"update_timestamp": "2017-02-07T17:33:30.001222Z"
}

⚠️ Some banks do not return an available balance in their online channels, meaning that available and current balances will be the same - unless overdraft is applied.
