so i had a commission on fiverr (i work as a roblox scripter there), and someone hired me to make an avatar shop with his UGC (from a group), i tried so many times to make a script that fetches items automatically based on the bits but i keept getting 400 error , so i got to vs code with python and started working 
this is what i did:
import requests
group_id = 10447595 # target Group ID
url = "https://catalog.roblox.com/v1/search/items/details"
params = {
"CreatorType": "2", # only items created by the group
"CreatorTargetId": group_id, # id
"Category": "11",
"Subcategory": "26",
"SortAggregation": "5",
"SortType": "0",
"Limit": "30"
}
# visit https://create.roblox.com/docs/projects/assets/api#marketplace-api for more details on the parameters
def fetch_all_items():
items = []
next_cursor = None
while True:
if next_cursor:
params["Cursor"] = next_cursor
response = requests.get(url, params=params)
if response.status_code == 200:
data = response.json()
print(f"Fetched {len(data['data'])} items...")
items.extend(data['data'])
next_cursor = data.get('nextPageCursor')
if not next_cursor:
break
else:
print(f"Failed to fetch data. Error code: {response.status_code}")
break
return items
def save_items_to_file(items, filename="items.txt"):
with open(filename, "w") as file:
file.write("return {\n")
for item in items:
if 'name' in item and 'id' in item:
file.write(f' {{Id = {item["id"]}, Name = "{item["name"]}"}} ,\n')
file.write("}\n")
items = fetch_all_items()
save_items_to_file(items)
print("All items have been saved to 'items.txt'.")
it was EXTREMELY helpful, this solved my problem really fast cuz i dont need to go search manually and changing Cursor manually !!!
also u can andjust the output, in my case i set it to:
return {
{Id = 17164022736, Name = "Milkshake"} ,
{Id = 12854443148, Name = "Walkie-Talkie"} ,
{Id = 12514992588, Name = "Black Cyber Gun"} ,
{Id = 76626061310386, Name = "cutecore strawberry purse"} ,
{Id = 12854448906, Name = "Security Flashlight"} ,
{Id = 12514977913, Name = "White Cyber Gun"} ,
{Id = 12514797703, Name = "Pink Cyber Gun"} ,
{Id = 12854437403, Name = "Security Guard Badge"} ,

}
