Creating a bill always sets value to 0.00

1

Hi, I wonder if anyone is able to assist. I have been attempting to create bills using the API. The bill creates fine but the value sets as 0.00. I have added line items, I’ve set the total value and lots of different methods but none of them appear to work. Does anyone know why this might happen.

def create_freeagent_bill():
“”" Create a bill in FreeAgent. “”"
refresh_token_if_needed()

headers = {'Authorization': f'Bearer {ACCESS_TOKEN}', 'Content-Type': 'application/json'}

bill_data = {
    'bill': {
        'contact': f'https://api.freeagent.com/v2/contacts/{CONTACT_REFERENCE}',
        'dated_on': datetime.now().strftime('%Y-%m-%d'),
        'due_on': datetime.now().strftime('%Y-%m-%d'),
        'reference': f'TestBill{datetime.now().strftime("%Y%m%d")}',
        'status': 'Draft',
        'input_total_values_inc_tax': True,  # Allow FreeAgent to calculate total
        'bill_items': [
            {
                'description': 'Manual Test Entry',
                'quantity': '1.0',
                'unit_price': '10.00',  # Ensure unit_price is passed as a string
                'sales_tax_rate': '20.0',  # Passed as a string
                'category': '250'
            }
        ]
    }
}

response = requests.post(FREEAGENT_BILL_URL, json=bill_data, headers=headers)
logging.debug(f"Bill creation data: {bill_data}")
if response.status_code == 201:
    logging.info("Bill created successfully.")
    logging.debug(f"Full Response: {response.json()}")
else:
    logging.error(f"Failed to create FreeAgent bill: {response.status_code}, {response.text}")
