I am trying to automate some simple updating of a Google spreadsheet and I'm using the gspread library to do so. One task that is critical and not currently supported by gspread is the ability to add comments to a specific cell (there's an open issue for this and even a gist solution but I was getting a 404 error when trying to use it).
I know that the Google Drive API (v3) supports adding comments as described here, but I'm having issues with authenticating and could use some help.
What I have/know:
I have already setup the OAuth 2.0 and registered for the API through Google, as well as have the client_secret.json in my directory, but my knowledge of web requests and responses is limited so going through the Drive API documentation hardly makes sense. I know in order to create the comments I will have to make use of anchors and specify the cell location using column/row numbers.
What I'm stuck on:
When using the Google API Explorer, I'm getting a 400 error with the message: The 'fields' parameter is required for this method. How can I make the POST request using my authentication? I think from there I'd be able to actually add the comments myself.
