About Open Banking Transactions

Open Banking transactions represent all transaction activity pulled directly from customers' bank accounts through secure banking APIs (such as AISP - Account Information Service Provider in the UK). This includes:

• All transactions on the bank account, not just Mint-related activity
• Purchases, refunds, transfers, direct debits, standing orders, etc.
• Transactions from all merchants and service providers
• Both incoming and outgoing transactions
• Raw bank statement data with original descriptions and amounts

This data provides a complete view of the customer's bank account activity and is used for:

• Account reconciliation and matching
• Financial analysis and insights
• Transaction categorization and reporting
• Identifying Mint-related transactions within the broader account activity

Note: This is different from funds transfers, which are specifically debits or credits initiated by Mint to merchants.

Bank Account Filtering

The search supports multiple bank account identifier parameters (iban, routing_account_number, bank_account_id) that are applied exclusively:

• All provided bank account identifiers must match the same bank account
• If multiple identifiers are provided but don't all correspond to the same account, no records will be returned
• This ensures data consistency and prevents accidental cross-account queries

Examples:

• ✅ bank_account: "BA.123" + iban: "GB82WEST12345698765432" (if they match the same account)
• ❌ bank_account: "BA.123" + iban: "GB82WEST99999999999999" (if they match different accounts)
• ✅ iban: "GB82WEST12345698765432" only
• ✅ routing_account_number: {...} + bank_account: "BA.123" (if they match the same account)
