CARD transaction missing transactions made in payments

After retrieving data from my bank account (Mizrachi) and my credit card (Visa Cal), I noticed that the amount charged during the credit card's billing cycle does not match the total amount of transactions made on the card within that same billing period. Upon investigation, I found a transaction belonging to a multi-payment purchase that was made a year prior. I used the following endpoint: https://{API_PREFIX}.open-finance.ai/v2/data/transactions.
Any suggestions how to retrieve all the transactions that my account been charge in a specific month?
