Bank account transactions

A transaction is a record of an amount of money paid into, or paid out of, a bank account.

Debits and credits

Every bank account transaction is either a credit or a debit:

A credit adds money to the account, which increases the account balance.
- Examples of credit transactions include payments received and earned interest.
A debit takes money from the account, which decreases the account balance.
- Examples of debit transactions include payments sent and fees charged.

In the transactions API, the balance-change-direction field indicates whether the transaction is a credit or debit.

Every transaction records the source of the money being credited or debited.
