What should be the callback when using GitHub Actions?

[arnonrdp]

Question

My application runs through a GitHub Action.What should my callback be?
I have a cron job that makes my app post some news at a certain time of day.
But after this Twitter update to v2, it never worked again.

Então, atualizei aquele antigo modelo:

# OLD - It worked in v1
auth = OAuthHandler(getenv('API_KEY'),
                    getenv('API_KEY_SECRET'))
auth.set_access_token(getenv('ACCESS_TOKEN'),
                      getenv('ACCESS_TOKEN_SECRET'))
api = API(auth)
api.verify_credentials()

But I can't get this to work.
Looks like it got more complex.

Relevant Code

def twitter_connect(tweet_list):
    auth = OAuth2UserHandler(client_id=getenv('CLIENT_ID'),
                             redirect_uri='https://github.com/arnonrdp/Bot-Deschamps-Newsletter',
                             scope=['tweet.write'],
                             client_secret=getenv('API_KEY_SECRET'))
    url = auth.get_authorization_url()
    access_token = auth.fetch_token(url)
    api = Client(access_token)

    try:
        api.verify_credentials()
        print('Good news, you are logged!')
        prepare_tweet(tweet_list, api)
    except Exception as e:
        print('Bad news, will try again in 2 minutes.\n', e)
        sleep(120)
        twitter_connect(tweet_list)

You need to actually use the authorization URL, instead of just passing it to OAuth2UserHandler.fetch_token.
See https://tweepy.readthedocs.io/en/v4.14.0/authentication.html#oauth-2-0-authorization-code-flow-with-pkce-user-context.

You can continue using OAuth 1.0a User Context with Twitter API v2 though.

Also note, Client does not have a verify_credentials method.

[Harmon758]

The only full traceback you've provided is for a oauthlib.oauth2.rfc6749.errors.MissingCodeError involving OAuth 2.0 Authorization Code Flow with PKCE, which my original answer addresses.

You've provided no code that is using OAuth 1.0a User Context with Twitter API v2.

You've also provided no code that is using a loop of any kind, so I'm not sure how you'd be encountering an infinite loop, unless you're using a process manager or something, which would be well outside the scope of the library.

So no, you have not provided the full traceback and the relevant code for any "error 453" or infinite loop you're encountering from using OAuth 1.0a User Context with Twitter API v2.

As for these two questions, I'm not sure what callback you're referring to, and again, you can continue using OAuth 1.0a User Context with Twitter API v2. I'm not going to keep answering the same question over and over again.

The loop I mention is about our conversation lol.

Here is the code and Traceback:

Just to summarize/explain: The application takes a newsletter, turns it into a list, and posts each list item as a tweet.

EDIT:

I know line 13 is wrong, but I am stuck in here, I don't know how to proceed with this authentication.

[Harmon758]

If you insist on using OAuth 2.0 Authorization Code Flow with PKCE with GitHub Actions, you'll need to use a refresh token.
https://developer.twitter.com/en/docs/authentication/oauth-2-0/authorization-code

I'm not sure why you would do this instead of just continuing to use OAuth 1.0a User Context though, if you're not using any endpoints that require OAuth 2.0 Authorization Code Flow with PKCE.

[arnonrdp]

Because I think OAuth 1.0 is not working to me, it says:

453 - You currently have access to a subset of Twitter API v2 endpoints and limited v1.1 endpoints (e.g. media post, oauth) only. If you need access to this endpoint, you may need a different access level.

The only thing my app does is post tweets.

[Harmon758]

Again, you need to provide to provide the full traceback and the relevant code.
I'm not going to keep telling you this.

[leonardo-cordeiro]

Try this:

from tweepy import Client


def twitter_connect(tweet_list):
    client = Client(
        consumer_key=getenv('API_KEY'),
        consumer_secret=getenv('API_KEY_SECRET'),
        access_token=getenv('ACCESS_TOKEN'),
        access_token_secret=getenv('ACCESS_TOKEN_SECRET')
    )

    prepare_tweet(tweet_list, client)

[arnonrdp]

That what I was looking for!

Worked perfectly, thanks bro.

[Harmon758]

I've been telling you to do this for two days now, including in my original answer, while you repeatedly kept saying this errored for you, without providing the full traceback or relevant code. I'm not sure if this was to purposefully waste my time or antagonize me, but I certainly don't appreciate it.
