Zapier Python Script Not Capturing All Order Items

The integration between Shopify and Google Sheets via Zapier is not capturing every purchased item when processing new paid orders. Only the first product is extracted even when multiple items are present, leaving crucial product details unrecorded. I attempted to use a Python script to parse customer details such as address, email, and phone number along with product information, but the script fails to iterate through all the items. Consider the revised code snippet below that adopts different variable names and structure to better manage multiple product entries:

def merge_parts(data_string):
    combined = []
    segments = data_string.split('|')
    for index in range(0, len(segments), 2):
        if index + 1 < len(segments):
            combined.append(f"{segments[index]}-{segments[index+1]}")
    return combined


def retrieve_safe(item_list, pos):
    return item_list[pos] if 0 <= pos < len(item_list) else 'undefined'

input_data = {
    'quantities': '3;2',
    'items': 'Alpha;Beta',
    'timestamps': '2022-05-01|09:30|2022-05-01|09:35',
    'contact': '5551234567',
    'note': 'Deliver ASAP',
    'address': '456 Central Ave',
    'status': 'confirmed',
    'last_name': 'Smith',
    'first_name': 'Alice',
    'email': '[email protected]'
}

output_results = []
quant_arr = input_data.get('quantities', '').split(';')
item_arr = input_data.get('items', '').split(';')
time_arr = merge_parts(input_data.get('timestamps', ''))

for idx, item in enumerate(item_arr):
    output_results.append({
        'quantity': retrieve_safe(quant_arr, idx),
        'item': item,
        'phone': input_data.get('contact'),
        'note': input_data.get('note', ''),
        'address': input_data.get('address'),
        'status': input_data.get('status'),
        'last_name': input_data.get('last_name'),
        'first_name': input_data.get('first_name'),
        'email': input_data.get('email'),
        'time': retrieve_safe(time_arr, idx)
    })

return output_results

The code generally appears sound, but I have seen similar issues when handling multiple product entries. In my experience, a common pitfall is assuming that all data strings will split neatly as expected. Adding validation to ensure that the expected number of tokens exist before proceeding can prevent the extraction of only the first item. Moreover, experimenting with alternative methods for iterating over data collections has sometimes offered a better solution, such as creating functions to encapsulate each data component’s handling, thereby reducing potential indexing errors.

i wonder if the splitting gets messed up. try checking for empty parts and maybe using zip_longest to merge lists, that might fix the looping inconsistancy. dont know, but some indexing mishap seems to be the culprit.
