Organizze API

Authentication

Basic auth with User-Agent header (required — returns 400 without it):

import os, base64, urllib.request, json

api_key = os.environ.get('ORGANIZZE_API_KEY', '')
email = 'user@example.com'  # Organizze account email
credentials = base64.b64encode(f'{email}:{api_key}'.encode()).decode()
headers = {
    'Authorization': f'Basic {credentials}',
    'Content-Type': 'application/json',
    'User-Agent': 'myapp/1.0'
}
BASE = 'https://api.organizze.com.br/rest/v2'

Key Conventions

• Amounts: always in cents (amount_cents). Negative = expense/debit, positive = income/credit.
• Pagination: /transactions and /invoices default to current month/year. Use ?start_date=YYYY-MM-DD&end_date=YYYY-MM-DD. Dates are rounded to full months.
• Credit card transactions: have credit_card_id set; bank account transactions have it as null.
• Transfers: use /transfers endpoint, not /transactions. Creates two linked records (oposite_transaction_id).

Common Patterns

List transactions for a period

req = urllib.request.Request(
    f'{BASE}/transactions?start_date=2026-02-01&end_date=2026-02-28',
    headers=headers
)
with urllib.request.urlopen(req) as r:
    txs = json.loads(r.read())

Create a simple transaction

body = json.dumps({
    'description': 'Mercado',
    'date': '2026-03-01',
    'amount_cents': -5000,
    'paid': False,
    'account_id': 123,
    'category_id': 456,
    'notes': 'Compras da semana',
    'tags': [{'name': 'alimentacao'}]
}).encode()
req = urllib.request.Request(f'{BASE}/transactions', data=body, headers=headers, method='POST')

Create installment transaction (correct way)

# Use installments_attributes — NOT total_installments (ignored by API)
body = json.dumps({
    'description': 'Notebook',
    'date': '2026-02-01',
    'amount_cents': -150000,
    'paid': False,
    'credit_card_id': 789,
    'category_id': 456,
    'installments_attributes': {'periodicity': 'monthly', 'total': 12}
}).encode()
req = urllib.request.Request(f'{BASE}/transactions', data=body, headers=headers, method='POST')
# Creates 12 monthly installment records automatically

Create recurring (fixed) transaction

body = json.dumps({
    'description': 'Aluguel',
    'date': '2026-03-05',
    'amount_cents': -150000,
    'paid': False,
    'account_id': 123,
    'category_id': 456,
    'recurrence_attributes': {'periodicity': 'monthly'}
}).encode()
# periodicity options: monthly, yearly, weekly, biweekly, bimonthly, trimonthly

Create a transfer between accounts

body = json.dumps({
    'debit_account_id': 111,   # source account (money leaves)
    'credit_account_id': 222,  # destination account (money arrives)
    'amount_cents': 50000,
    'date': '2026-03-01',
    'paid': True
}).encode()
req = urllib.request.Request(f'{BASE}/transfers', data=body, headers=headers, method='POST')
# Credit cards are NOT accepted as transfer source or destination

Update/delete recurring or installment transactions

# Update this and future occurrences
body = json.dumps({'amount_cents': -160000, 'update_future': True}).encode()
# Update ALL occurrences (including past — may affect balance)
body = json.dumps({'amount_cents': -160000, 'update_all': True}).encode()

req = urllib.request.Request(f'{BASE}/transactions/97', data=body, headers=headers, method='PUT')

Check invoices due on a specific date

req = urllib.request.Request(f'{BASE}/credit_cards', headers=headers)
with urllib.request.urlopen(req) as r:
    cards = json.loads(r.read())

for card in cards:
    req = urllib.request.Request(f'{BASE}/credit_cards/{card["id"]}/invoices', headers=headers)
    with urllib.request.urlopen(req) as r:
        invoices = json.loads(r.read())
    for inv in invoices:
        if inv['date'] == target_date and inv.get('balance_cents', 0) != 0:
            pending = abs(inv['balance_cents']) / 100
            print(f'{card["name"]}: R$ {pending:.2f} pendente')
