403 Error #373

vlall · 2024-02-21T19:24:44Z

Hello, I'm getting a 403 error but the site seems to be up and all services are functional on Trello. Not sure if this is a Cloudflare server-side issue with Trello or an API issue.

Recreate the issue with this:

from trello import TrelloClient
TrelloClient(TRELLO_API_KEY).list_boards()

Not sure how maintained this project is, but for those who want a workaround, the official API docs here with the requests python library works for me: https://developer.atlassian.com/cloud/trello/rest/

But you have to do your own parsing.

beretem · 2024-02-22T01:49:33Z

Response from Trello support:

We recently released a change in making GET requests. Trello’s API will no longer permit supplying a body with a GET request and will now be blocked with a 403 response. For more information: https://developer.atlassian.com/changelog/#CHANGE-1459

To resolve these errors, you should remove the request body in your API GET requests.

Hope this helps but let me know if you have any more questions or concerns.

11am: I set up a Discord bot with Trello integration and everything is good
12pm: Trello updates its API policies and everything goes down the drain lol

It needs to be fixed here, using requests in Python and it started working 🙌

Problem is located here.

py-trello/trello/trelloclient.py

Line 221 in a628d54

data = json.dumps(post_args)

When files are not specified in the case for GET calls, it will attempt to convert an empty dictionary to JSON string.
This will be sent as "{}" in the body of our GET request.

Currently, I am monkey patching with the following to get by.

Tested and the code worked. This is a quick fix for those who cannot wait for package update.

This looks to be a permanent change to the API as per: https://developer.atlassian.com/changelog/#CHANGE-1459

Thanks to @jitvimol for the monkey patch -- that did the trick for me!

FYI : @kaikok is the one who develop the code. (I tested his code)

kaikok · 2024-03-16T02:38:43Z

Thank you @jitvimol for testing out the fix and the attribution! Glad that it was useful to everyone here.

frankiexo · 2024-03-16T19:29:20Z

Monkey patch from @jitvimol worked for me. Just be careful, when you import only part of py-trello module like me by from trello import TrelloClient then you need to add also import json

joncle · 2024-03-25T22:23:25Z

Not fully tested but just wondering if it might be an idea that the library uses its own requests.Session that always blanks out the data (and anything else necessary) for GETs as the default to http_service instead of requests.

Far from properly tested and just throwing it out there in case it's of use (and might just be a possible alternative monkey patch).

from trello import TrelloClient
import requests

class TrelloSession(requests.Session):
    def request(self, method, url, **kwargs):
        if method == 'GET':
            kwargs = {**kwargs, 'data': None}
        return super().request(method, url, **kwargs)

Then initialise the client as (although TrelloSession() would become the default)

client = TrelloClient(api_key=api_key, token=api_token, http_service=TrelloSession())

For personal needs, I have forked this repository and merged two pending PRs into the new repository.
https://github.com/Konano/py-trello-api

As a temporary solution, I have also uploaded the new package to Pypi. You can download the fixed py-trello with this command:
pip install py-trello-api==0.20.0

I hope this helps someone in need.

BTW it does not support 2.7 / didn't test 3.x but thank for the contribution!
