does it work for createTweet

[AmarnathCJD]

Does it work for /CreateTweet?

[iSarabjitDhiman]

Yes it does

[AmarnathCJD]

do we need to set ct0 , auth headers and csrft token?, I tried without them and it generated one for CreateTweet but it threw auth duplicate error, with them also same

[iSarabjitDhiman]

Here are a few things that might help:

• Make sure the tweet text is unique each time (X (Formerly Twitter) doesn't allow to publish duplicate tweets.
• Use session
• Attach X-Client-Transaction-Id
• Use fresh auth token / cookies (try grabbing them from the browser if it works, you might have some bugs in your code)

Hello, I am an engineer in Japan who does reverse engineering and communication analysis.

Sometimes, I get an error like this:

clientTransaction error: Exception("Couldn't get KEY_BYTE indices")

Do you know why?

[AmarnathCJD]

I have settled for selenium, feed the cookies and click a button, that's it

I think its the Header. I changed it and it worked. Its Header selective

Perfect. What value in the header exactly? Just so that others could fix the same if they are facing the same issue.

Thanks.

@Thankgod20 hey, could you let us know what header did you add to fix that?
