Gmail API - Error 400: redirect_uri_mismatch

[Depp]

Hi,

I am trying to access Gmail API using Al Sweigart book, however I am getting "Error 400: redirect_uri_mismatch". Attached is the print screenshot for your reference.

I used the command line "python quickstart.py" on the command prompt when this error occured.

Please help me to figure out as I am a beginner!

Thank you in advance :)

You most link to what you try to use,i guess it's the EZGmail.
Then Gmail API quickstart.py where i guees you not followed all instruction as it fail for OAuth 2.0

Also EZGmail is broken issues
code is open.
I would skip this lesson to much trouble as he has not updated EZGmail what this lesson use.
