Authentication Error V2 API

https://api.upstox.com/v2/login/authorization/dialog?response_type=code&client_id=28ebb9a0-1b29-4955-8c6a-22b826f06a7c&redirect_uri=https://trading.tech/

What’s wrong with this authentication url?
I am getting this error.

{"status":"error","errors":[{"errorCode":"UDAPI100068","message":"Check your 'client_id' and 'redirect_uri'; one or both are incorrect.","propertyPath":null,"invalidValue":null,"error_code":"UDAPI100068","property_path":null,"invalid_value":null}]}

I watched this YouTube tutorial , multiple authentication code from web, that also didn’t work/
Is the authentication service down?

Hi @Sudharshan,

Rest assured, the authentication service is up and has not experienced any downtime.

As the error message indicates, it seems there may be a mismatch with your Client ID or Client Secret. Please double-check to ensure you’re using the correct credentials from your “My Apps” section.

Thank you!
