I’m upgrading from Python dwolla 2.2 to 2.3 and getting an error in oauth.get in the sandbox. I haven’t made any changes to my code yet, I was just testing things that were working fine with 2.2
```

After rebooting the dev server I’m getting an error I got previously - there’s no ‘Success’ key in the response dict:

@coldants, This may be a configuration issue. What do you have set as your host value? do you have `sandbox_host = 'https://sandbox.dwolla.com/'`

Yes, I’m not overriding that and I have sandbox set to True. The only other constants I’m overriding are client\_secret and client\_id

@spencer - anything further on this? I would very much like my website to continue working after 12/4 but I can’t put 2.3 into production when almost nothing works in the sandbox.

So here is a snippet from your examples section that will demonstrate an error in dwolla-python 2.3
>
I’m running that code in a virtualenv with just dwolla-python 2.3 installed, and it’s looking for a key that’s not in the response.
```

@coldants, Thanks for sharing your gist. I wasn’t able to recreate the issue, however I believe oauth.get requires you to pass in a redirect\_uri which should match the value that was used in the oauth.genauthurl() request. Something like:
```python
access_set = oauth.get("Z/KHDIyWO/LboIGn3wGGs1+sRWg=", "http://requestb.in/122rdhc1")
print(access_set)
```

@spencer I think it used to but no longer:
```
Traceback (most recent call last):
File "test.py", line 23, in
access_set = oauth.get("Z/KHDIyWO/LboIGn3wGGs1+sRWg=", "https://requestb.in/1nwwqrr1")
TypeError: get() takes exactly 1 argument (2 given)
```
Do I have some bad settings? The gist is the only code I wrote. It’s a new virtualenv, Python 2.7, all I did was pip install dwolla. Here’s the output from pip freeze:
certifi==2017.11.5
chardet==3.0.4
dwolla==2.3.0
funcsigs==1.0.2
idna==2.6
mock==2.0.0
pbr==3.1.1
requests==2.18.4
six==1.11.0
urllib3==1.22
