App is blocked by Google

[OZoneGuy]

I tried using gcalcli list for the first time and it opened a browser tab asking for verification. After choosing the account I got the following page:

Not sure if this is intended or known. I tried this with my personal account and my University's account and I got the same result in both scenarios. I tried using the --noauth_local_webserver option and got the same result after logging in.

Not sure how to solve it, and I couldn't find any similar issues online.

I am tried using both gcalcli and gcalcli-git found on the AUR.

Your best bet is to follow the steps here to get your own API keys: https://github.com/insanum/gcalcli#login-information

Though I have a problem with that where it keeps logging me out and making me re-authenticate every week or so. I may need to get it verified for it to stick.

[OZoneGuy]

Maybe. I tried creating an API key like the README suggests, but then I get this error page:

I haven't used the Google auth API in a long time, so I don't know what has changed or what needs to be done.

In the Cloud Console go to OAuth Consent Screen -> Edit App -> Click continue twice to get to "Test users" and you should be able to add your email.

Steps, loosely following comment #497 (comment)

1. Google Developers Console https://console.developers.google.com

• create a new project, e.g., gcalcli

2. + Enable APIs and Services"

• enable Google Calendar API
• go back to project gcalcli in Developers Console

3. Credentials section in left menu

• + Create Credentials > OAuth client ID
• Application type Desktop App
• name gcalcli
• The credentials produced here are needed in step 5

4. OAuth consent screen section in left menu

• I was restricted to choose External users
• OAuth consent screen
  • App name: e.g., gcalcli
  • User support email: e.g., put your own gmail address
  • App domain: leave all blank
  • Developer contact information: put your own gmail address
• Scopes: choose all calendar API related stuff plus more if necessary - I did trial and error here ...
• Test users: again I put my own gmail address here
• Summary: click "Back to dashboard" at bottom
• leave Publishing status as Testing so your own gcalcli is not published to the world

5. call gcalcli from command line

• Use credentials from step 3 in shell command, e.g. for Google agenda view: gcalcli --client_id "your client ID ending in ...apps.googleusercontent.com" --client_secret "your client secret" agenda
• as my default browser is Firefox I had to copy the URL after Your browser has been opened to visit: (shown in shell after above command) and open it in chromium > follow steps and give permissions to gcalcli
• in shell, Google calendar agenda is shown 🎉
• to facilitate the command line call from above to just gcalcli agenda, create a file ~/.gcalclirc with

    --client_id=clientidfromstep3....apps.googleusercontent.com
    --client_secret=clientsecretfromstep3

SO easy! :'D

Update 1: Chromium or Firefox?

With gcalcli v4.0.0a3 from the Linux Mint/Ubuntu repos, the Google website confirmation only works in Chromium. The pip-installed version gcalcli v4.3.0 makes the Google website confirmation process possible in Firefox.

Update 2: --client_id or --client-id?

The above steps worked well with gcalcli v4.0.0a3 from the Linux Mint/Ubuntu repos. However, gcalcli v4.3.0 installed with pip warns:

WARNING: --client_id has been deprecated and will be removed in a future release.
Please use "--client-id", instead.
WARNING: --client_secret has been deprecated and will be removed in a future release.
Please use "--client-secret", instead.gcalcli v4.3.0

If this appears, change the call parameters accordingly in shell command and if applicable in ~/.gcalclirc.

Update 3: upgrade six

When running into error AttributeError: module 'six.moves' has no attribute 'collections_abc' then make sure to upgrade six to the latest version, e.g., by pip3 install --upgrade six.

I tried what @aurisnoctis said. However, I couldn't be successful. Is there any other way around to make this work out? Also, I tried with chromium browser.
Thank you.

[reeseovine]

I'm using Firefox and it gives me the option to continue with a warning:

Look at Update 1 here. Using the pip version is what allows me to use Firefox.

Thanks @aurisnoctis Really helpful.

I had been using this awesome app for about a month, and suddenly today, Google tells me that the app is blocked, and there's nothing I can do to get it authenticated. I had already set it up with my own GCP OAuth credentials, using .gcalclirc and it was working fine. Also, "Allow less secure apps" setting on my Google Account is "ON". I don't understand, I've been developing Google Cloud Platform apps for a few years and I was always given the option to "continue" and "allow" the app, now there is just no option, only a "Blocked" message. Any ideas?

[avanavana]

I solved this issue using the following resources:

1. Make sure to turn on your Google account's setting for "Allow less secure apps"
2. Visit Google's "Display Unlock Captcha" page and click "Continue" to remove the security block.

Hello all,
what about generating a token from this page ? https://myaccount.google.com/apppasswords
Could it solve this problem ? I think gcalcli is not ready to use such token but it could be a great improvment.

[andersfylling]

Same issue. I'm trying to read my schedule from my work account, where I can't change any of the above settings.

I tried this guide for creating the client id and client secret and it worked flawlessly. I didn't even have to run "DisplayUnlockCaptcha" nor enable Less Secure Apps.
