kiteconnect.exceptions.TokenException: Token is invalid or has expired.

Hi support,

I am getting the following exception when I am trying to use the "generate_session" API to generate the access token from the request token.

Stack Trace:---------------------------------------------------------------------------

Please help me resolve this issue as soon as possible.

val = kite.generate_session(request_token,api_secret=api_secret)

You need to re-check if you are using correct request_token and api_secret values here.
Refer this document for complete flow.

Hi @rakeshr ,

Thanks for the response.
I have made sure that the api key and the api secret key I am using are correct.

I am following these steps to generate the access token:

1. create kite object using the api and api_key: "kite = KiteConnect(api_key=api_key)"
2. Log in to the url as returned by kite.login_url()
3. Copy the request_token from the redirected url
4. Paste that request_token in the first argument of the api generate_session: "val = kite.generate_session(request_token,api_secret=api_secret)"
5. Set the access_token as: "kite.set_access_token(val['access_token'])"
6. Re-run the python file with the request_token.

Please let me know if I am doing something wrong in the above mentioned steps, or something I might have missed.

Akash

You can check out this thread.

Hi @sujith ,

I have already scanned the forum articles thoroughly to look for the solution and tried everything already mentioned, but to no avail. Please let me know if I am doing anything wrong in the above steps. I think that there might be some other issue in this.

I am able to successfully generate the request token with the steps mentioned in the previous comment, but I am not able to understand why this request token is not being accepted by the system.
This is what I get when I follow the URL generated by the kite.login_url():
http://127.0.0.1/?action=login&;status=success&request_token=xxxxxxxxxxxxxxxxxxx

It can be used only once and has a validity of a couple of minutes only.

Hi @sujith

I know that already. I am not able to generate the access token even once. I want to understand why the generate_session api is not able to accept the generated request token

sujith

A request token can be used only once and it is only valid for a couple of minutes. If you try to re-use the invalid request token then you won't be able to generate a session.
You need to store the generated access token and use that in the subsequent runs. That is what is mentioned in the above-linked thread.

akash_mittal

Yes, I am generating a new request token for every run, and not using the previous token. I have not been able to generate the access token even once.

akash_mittal

The problem is that I am not able to get past the "generate_session" step itself. The system is rejecting the freshly generated request token, because of some unknown reason.

sujith

Can you give us the status code? Is it 400 or 403?

akash_mittal

Where can I see the status code?

akash_mittal

@sujith , can you please tell me how to retrieve the status code?

sujith

You can run pykiteconnect in debug mode and see that response status code.

akash_mittal

@sujith , the status code is 403

sujith

It means the request token is expired or invalid.

akash_mittal

@sujith, would you be able to help if I provide you with my api_key and api_secret? It would be a great help

rakeshr

@akash_mittal
Yes, you can DM us with api_key and api_secret, you are facing issue. Never paste your API-related keys and token on a public platform.

akash_mittal

I have messaged you the keys. Please check

akash_mittal

It worked!
Apparently, the api_key and api_secret keys while reading from a text file were being appended with a \n. The generate_session api started working after i removed the \n.
Thanks a lot for your help and support!
