Hi @dmoore247 , welcome to the forum!
Yes this can be a little confusing…
I’m not sure which Python SDK you are using, but with the Next Gen one, the issue is that you need to send the original shared link to download the files.
I have prepared an example for you:
import os
import shutil
from io import BufferedIOBase
import dotenv
from box_sdk_gen import (
BoxCCGAuth,
CCGConfig,
BoxClient as Client,
BoxAPIError,
Items,
)
from box_sdk_gen import DownloadsManager
ENV_CCG = ".ccg.env"
class ConfigCCG:
"""application configurations"""
def __init__(self) -> None:
dotenv.load_dotenv(ENV_CCG)
# Common configurations
self.client_id = os.getenv("CLIENT_ID")
self.client_secret = os.getenv("CLIENT_SECRET")
# CCG configurations
self.enterprise_id = os.getenv("ENTERPRISE_ID")
self.ccg_user_id = os.getenv("CCG_USER_ID")
self.cache_file = os.getenv("CACHE_FILE", ".ccg.tk")
def main():
conf = ConfigCCG()
ccg_conf = CCGConfig(
client_id=conf.client_id,
client_secret=conf.client_secret,
enterprise_id=conf.enterprise_id,
)
auth = BoxCCGAuth(ccg_conf)
client = Client(auth)
web_link_url = "https://nihcc.app.box.com/v/ChestXray-NIHCC"
user = client.users.get_user_me()
print(f"User: {user.id}:{user.name}")
try:
shared_folder = (
client.shared_links_folders.find_folder_for_shared_link(
boxapi="shared_link=" + web_link_url
)
)
print(f"Shared Folder: {shared_folder.id}:{shared_folder.name}")
print("#" * 80)
print("Type\tID\t\tName")
os.chdir("downloads")
items = client.folders.get_folder_items(
shared_folder.id, boxapi="shared_link=" + web_link_url
)
download_items(client, items, web_link_url)
os.chdir("..")
except BoxAPIError as e:
print(f"Error: {e}")
def download_items(client: Client, items: Items, web_link_url):
for item in items.entries:
if item.type == "folder":
if not os.path.exists(item.name):
os.mkdir(item.name)
os.chdir(item.name)
# print the folder name
print("-" * 80)
print(f"\n\n{item.type.value}\t{item.id}\t{item.name}")
print("-" * 80)
items = client.folders.get_folder_items(
item.id, boxapi="shared_link=" + web_link_url
)
download_items(client, items, web_link_url)
os.chdir("..")
if item.type == "file":
print(f"{item.type.value}\t{item.id}\t{item.name}", end="")
# check if item name ends with .tar.gz
if item.name.endswith(".tar.gz"):
print("\t .tar.gz skipped")
continue
file_content_stream: BufferedIOBase = (
client.downloads.download_file(
item.id, boxapi="shared_link=" + web_link_url
)
)
with open(item.name, "wb") as f:
shutil.copyfileobj(file_content_stream, f)
print("\tdone")
if __name__ == "__main__":
main()
print("Done")
The result is (I’ve skipped the big .tar.gz files):

The trick in this Gen SDK is this line:
items = client.folders.get_folder_items(
item.id, boxapi="shared_link=" + web_link_url
)
It sends the shared link information, so it can be used as security context, otherwise it is looking for the folder/file in your own box instance, as opposed to NIHCC.
Let me know if this helps.

Hi @dmoore247
I was looking into the differences between the classic and next gen sdk.
So here is the same example for the classic SDK:
"""demo to download files from a box web link"""
import os
from boxsdk import JWTAuth, Client
def main():
auth = JWTAuth.from_settings_file(".jwt.config.json")
auth.authenticate_instance()
client = Client(auth)
web_link_url = "https://nihcc.app.box.com/v/ChestXray-NIHCC"
user = client.user().get()
print(f"User: {user.id}:{user.name}")
shared_folder = client.get_shared_item(web_link_url, "")
print(f"Shared Folder: {shared_folder.id}:{shared_folder.name}")
print("#" * 80)
print("Type\tID\t\tName")
os.chdir("downloads")
items = shared_folder.get_items()
download_items(items)
os.chdir("..")
def download_items(items):
for item in items:
if item.type == "folder":
if not os.path.exists(item.name):
os.mkdir(item.name)
os.chdir(item.name)
# print the folder name
print("-" * 80)
print(f"\n\n{item.type}\t{item.id}\t{item.name}")
print("-" * 80)
download_items(item.get_items())
os.chdir("..")
if item.type == "file":
print(f"{item.type}\t{item.id}\t{item.name}", end="")
# check if item name ends with .tar.gz
if item.name.endswith(".tar.gz"):
print("\t .tar.gz skipped")
continue
with open(item.name, "wb") as download_file:
item.download_to(download_file)
print("\tdone")
if __name__ == "__main__":
main()
print("Done")
This one ends up being simpler, because it already has the context of the shared folder, and automatically handles that extra parameter/header.
Let us know if this helps.
@rbarbosa Many thanks!
Very detailed examples, and they run in your environment!
A few things I struggle with these examples, and that is where to obtain the dependencies:
.jwt.config.json
- What %pip installs to run (I eventually figured this out for the first attempt)
- I did figure out CLIENT_ID, CLIENT_SECRET came from the dev console → OAUTH app …
- I don’t know where to start to find the
.ccg.env and what might go in there
CCG_USER_ID ? (20706451735)
- The
.ccg.tk CACHE_FILE? Does the api library create and manage this?
I eventually just manually downloaded, uploaded, unzipped the file with the miscellaneous. The publisher provided a simple python script with python requests calls for the .tar.gz files.
Thanks again,
Douglas
Hi
The examples I’ve sent were adapted from previous questions, and that is why you find multiple security models, my apologies for the inconsistency.
Hopefully they run in your environment also 🙂, let’s make sure that happens by taking a step back.
There are 3 types of authentication modes for Box applications:
- OAuth 2.0 - Requires user to manually authorize the application
- Client credential grants (CCG) - Requires client id, client secret, enterprise id or user id
- JSON Web Tokens (JWT) - Requires client id, client secret, enterprise or user id, private key, private key passphrase, key id.
To use in a script my recommendation is to go for CCG, it is the easiest to set up and move forward, but you will need to activate your developer account. I’m not sure if you are using a corporate account, a free account or a free developer account.
For this exercise I recommend you create a free developer account, if you haven’t done so yet, and if you need to, later apply this to your other box account.
To create a CCG app, goto your developer console, and click create app, and select custom app:
On the second dialog select Server authentication (Client Credentials Grant)
This next step depends on what you need your app to do, but considering just downloads from a shared link, you need this:
Next you need to go through the authorization process. Flip to the authorization tab and press review and submit. This will submit the request to your box administrator, which in this free developer account is you.
Now go back to you box.com app and open your administrator console, select apps on the right side menu, and you should see your app pending authorization. Authorize the app.
Note: Remember to do this process (submit+authorize) every time you change the application configurations.
While you are at you administration console, go to account and billing and take note of your enterprise id. in my case:
Go back to the developer console and take not of the client id and client secret:
You now have everything you need to instantiate a CCG Client using the box SDK.
In my examples I tend to use a .ccg.env or just a .env file, and then use the python-dotenv to import these. You can also use them directly in your script, this is considered less secure, but it is up to you to evaluate that.
The .env file looks like this (macOS/Linux):
# Common settings
CLIENT_ID = YOUR_CLIENT_ID
CLIENT_SECRET = YOU_CLIENT_SECRET
# CCG Settings
ENTERPRISE_ID = YOUR_ENTERPRISE_ID
CCG_USER_ID = THE_USER_ID
You can ignore the CCG_USER_ID, since it is used if you want your script to act as a user as opposed to a service account)
You can also ignore the .ccg.tk cache file, it is used to cache the token and re-use it if still within the 60 minutes window, but for this application, I’m assuming getting a new token every time wont be an issue.
I’ve ignored the .tar.gz files because they were too big for a simple demo. You can remove the if statement to download everything.
Here is a revised version for the classic SDK:
"""demo to download files from a box web link"""
import os
import dotenv
from boxsdk import CCGAuth, Client
ENV_CCG = ".ccg.env"
class ConfigCCG:
"""application configurations"""
def __init__(self) -> None:
dotenv.load_dotenv(ENV_CCG)
# Common configurations
self.client_id = os.getenv("CLIENT_ID")
self.client_secret = os.getenv("CLIENT_SECRET")
# CCG configurations
self.enterprise_id = os.getenv("ENTERPRISE_ID")
def main():
conf = ConfigCCG()
auth = CCGAuth(
client_id=conf.client_id,
client_secret=conf.client_secret,
enterprise_id=conf.enterprise_id,
)
client = Client(auth)
web_link_url = "https://nihcc.app.box.com/v/ChestXray-NIHCC"
user = client.user().get()
print(f"User: {user.id}:{user.name}")
shared_folder = client.get_shared_item(web_link_url, "")
print(f"Shared Folder: {shared_folder.id}:{shared_folder.name}")
print("#" * 80)
print("Type\tID\t\tName")
os.chdir("downloads")
items = shared_folder.get_items()
download_items(items)
os.chdir("..")
def download_items(items):
for item in items:
if item.type == "folder":
if not os.path.exists(item.name):
os.mkdir(item.name)
os.chdir(item.name)
# print the folder name
print("-" * 80)
print(f"\n\n{item.type}\t{item.id}\t{item.name}")
print("-" * 80)
download_items(item.get_items())
os.chdir("..")
if item.type == "file":
print(f"{item.type}\t{item.id}\t{item.name}", end="")
# check if item name ends with .tar.gz
if item.name.endswith(".tar.gz"):
print("\t .tar.gz skipped")
continue
# comment the above block to download all files
with open(item.name, "wb") as download_file:
item.download_to(download_file)
print("\tdone")
if __name__ == "__main__":
main()
print("Done")
To install the Box SDK’s, although optional, you should create an environment first.
For Box classic python SDK:
pip install boxsdk
or
pip install "boxsdknjwt]" - to include JWT support.
For the Next Gen Box SDK:
pip install box_sdk_gen
or
pip install "box_sdk_genljwt]" - to include JWT support.

Hi rbarbosa Box,
I wanted to create a similar post regarding the topic of this discussion. I read your solution, and I am currently doing the exact same thing. Unfortunately, it does not work, and I always receive the following error message:
Error: Message: Not Found

URL: https://api.box.com/2.0/shared_items
Method: GET
Context Info: None
I cannot figure out why. The URL I use works properly whenever I copy and paste it into my browser. The script should simply access the items from a shared folder that is not within our company and download the content, just like yours.
Here’s my code:
import json
from boxsdk import JWTAuth, Client
settings_file_path = './box_config.json'
auth = JWTAuth.from_settings_file(settings_file_path)
auth.authenticate_instance()
client = Client(auth)
user = client.user().get()
print(f"User: {user.id}:{user.name}")
folder_url = 'https://app.box.com/s/qbm...brv'
folder_password = '' #no password known
try:
folder = client.get_shared_item(folder_url, password=folder_password)
print(f"Shared Folder: {folder.id}: {folder.name}")
except boxsdk.exception.BoxAPIException as e:
print(f"Error: {str(e)}")
I wonder if I am missing something. The app is authorized by myself, and I have set up a free business account trial just for testing purposes.
I would be grateful for any assistance on this matter.
Best regards
