Hi I have been trying to resolve the get token issue for too long now. I contact xero support and follow the instructions as they said.
I followed each and every steps mentioned in the code document. I sent my console output to xero support, they asked me to regenerate the client secret, I changed it multiple times but still got invalid client error.
Here is the last email from xero api support
`Hi Bishwadeep
Our logs show the same error as before with the Client Secret being invalid. I would suggest raising this as an issue on the Github repo for the Python SDK and sample app.
It might also be useful to perform some debugging to ensure that the Client Secret is getting correctly used within your code.

Github: https://github.com/XeroAPI/xero-python-custom-connections-starter/issues
I would also suggest attempting the process in Postman: https://developer.xero.com/documentation/sdks-and-tools/tools/postman/#use-postman-with-custom-connections`
Here is the console log:

I have even sent the video to the api support and they confirmed I did it correctly.
