You don’t need to be paying GSuite user – regular free Google account is perfectly fine.
Google APIs have changed in such a way that it’s no longer possible to use pre-defined OAuth2 credentials, as were used in initial plugin versions, for free applications. And since the plugin was and still is free (and I never received a single donation for it) you now need to generate your own OAuth2 credentials.
What part of authentication steps you believe are not accurate? I specifically wrote very detailed instructions, so that even non-developers will be able to follow them. Alternatively, you may check Google Sheets API page – https://developers.google.com/sheets/api/quickstart/php – that has some “magic button” that _usually_ (but not always))) generates needed credentials with a single click.
Well, that was a quick an effective reply. Thanks!
Please follow your own links in the authentication description to see that it is not possible to create a project on the api library page etc. THe description is refined but does not match. I was able to find my way around, but I got lost when google put me to the choice to sign in on a paid Gsuite license or pay $15.000 to $75.000 for external verification.
The quickstart link worked for me.
Next it may be good to mention that the google sheets ID is not the last part of the sheet-url, but the part in the middle. This ID is the value between the “/d/” and the “/edit” in the URL of your spreadsheet.
Last but not least: donations suck. WordPress plugins need a better business model. If I would make any profit with my website I would be really glad to pay you your fair share. You really deserve it. Of course, same goes for Caldera Forms.
Weird – followed the links right now and they work for me just fine.
In any case I updated the instructions to use the quickstart shortcut for OAuth2 credentials generation and added screencasts for the rest of the installation/configuration procedure. Hopefully this will simplify the initial configuration for future users.
