Authentication issues

[IgnaceMaes]

I've been using the API for two months without any issues, up until a few days ago. There seems to be an issue with the Oauth token fetch.

To make sure the issue isn't on my side I created a new dummy application as follows:

from unsplash.api import Api
from unsplash.auth import Auth

client_id = "x"
client_secret = "x"
redirect_uri = "urn:ietf:wg:oauth:2.0:oob"
code = "x"

auth = Auth(client_id, client_secret, redirect_uri, code=code)
api = Api(auth)

api.user.me()

Running this code with a fresh authorization code gives the following error:

Traceback (most recent call last):
  File "C:\...\Python\Python36-32\lib\site-packages\unsplash\auth.py", line 56, in __init__
    self.access_token = self.get_access_token(code)
  File "C:\...\Python\Python36-32\lib\site-packages\unsplash\auth.py", line 72, in get_access_token
    code=code

  File "C:\...\Python\Python36-32\lib\site-packages\oauthlib\oauth2\rfc6749\errors.py", line 415, in raise_from_error
    raise cls(**kwargs)
oauthlib.oauth2.rfc6749.errors.InvalidGrantError: (invalid_grant) The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File ".\testauth.py", line 9, in <module>
    auth = Auth(client_id, client_secret, redirect_uri, code=code)
  File "C:\...\Python\Python36-32\lib\site-packages\unsplash\auth.py", line 59, in __init__
    raise UnsplashAuthError(e)
unsplash.errors.UnsplashAuthError: Unsplash Authentication Error: (invalid_grant) The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client.

I'm using Python 3.6 and the version of the dependencies specified in the requirements.txt.

Thanks for any help.

For anybody still wondering, I wasn't able to find a solution but ended up using another wrapper that works seamlessly https://github.com/salvoventura/pyunsplash

Hello, you need to provide correct client_id, client_secret, redirect_uri and code that returns from redirect uri. You can get token in unsplash developer panel.

@yakupadakli How do I used already saved access token so that I don’t have to authorise again again ?

Can you give example ?
