Use the linked-institution/:linkedInstitutionId/transactions endpoint to fetch transactions from a linked institution. This endpoint retrieves transaction data from the underlying provider (e.g., Plaid) and returns paginated results.

You can optionally filter by specific accounts using linkedInstitutionAccountIds, and specify a date range using startDate and endDate. If no date range is provided, transactions from the last 30 days will be returned.

Transactions are returned in reverse chronological order (most recent first).
