Hello Kaho Imai,

Thank you for reaching out to us.

When you see a "Redirect URI mismatch", the URI in Amelia and the URI in Google Developers Console are not the same.

Please go to Amelia Settings/Integrations/Google Calendar and make sure that the URI you see in there is your website's URL, ending with "wp-admin/admin.php?page=wpamelia-employees". For example, if your website is "yourwebsite.com", the redirect URI needs to be this:

https://yourwebsite.com/wp-admin/admin.php?page=wpamelia-employees

Is your website in HTTP or HTTPS? Please note that Google doesn't allow HTTP at this time, so if it's HTTP, you'll need to install an SSL certificate and move your site to HTTPS before you can continue.

After verifying that, please go to Google Developers Console, and in "APIs & Services" go to "Credentials". Under "OAuth 2.0 Client IDs" click on the name of your app:

In there, check the "Authorized redirect URIs" on the bottom of the page. Make sure that the URL has to be the same as it is in Amelia/Settings/Integrations/Google Calendar.

Hope this helps.

Hello Kaho Imai,

This is a proven solution that has been used thousands of times. As you have declined google access and this solution did not help you, in that case, you need to do a new/initial integration of the Google calendar in order to set it up properly. Unfortunately, since you have not set everything up correctly, we cannot do anything about it.

This time, please follow our documentation step by step and on this link https://wpamelia.com/configuring-google-calendar/ you will also see screenshots that explain everything step by step, and after that if you set everything up properly this time everything should work fine.
