I’m just trying out the UAT environment with Python, using some sample code. I’ve installed dwollav2 successfully, but get the following error.

name ‘account\_token’ is not defined.

The code is “transfer = account\_token.post(‘transfers’, request\_body)”

I think I need help understanding the commands to gain access to the API in the first place.

Thanks in advance.

Hey Mike,

Before you are able to use an `account_token` you’ll need to either generate one [here](https://uat.dwolla.com/applications) or obtain one by going through the OAuth flow. There are some examples at [https://github.com/Dwolla/dwolla-v2-python#account-tokens](https://github.com/Dwolla/dwolla-v2-python#account-tokens) that explain how to instantiate an `account_token` using either method. If you have any questions please let us know.

Hi Stephen,

I took another look at the instantiate code and am using that to define the account\_token using the access token and refresh token generated by the sandbox Apps page. Python is running into an error saying “name ‘client’ is not defined” . I thought client.Token would have been a function defined by the dwollav2 package.

account\_token = client.Token(access\_token = ‘…’, refresh\_token = ‘…’)

I was able to define client using some more code I found on github (below), but now Python is saying ‘os’ is not defined.

I entered the relevant app key and app secret from my UAT dashboard.

client = dwollav2.Client(  
key = os.environ[‘DWOLLA\_APP\_KEY’],  
secret = os.environ[‘DWOLLA\_APP\_SECRET’],  
on\_grant = lambda t: save(t)  
)
