Public Ticket #3171932
Redirect URL Mismatch


  • Nora Kramer started the conversation

    I am getting a "redirect URI mismatch" error when employees are trying to connect their calendars. This was originally built on a staging server, then migrated over to their live domain. I ran across this thread when trying to troubleshoot and am wondering if this has something to do with things and how to correct the issue. It is very frustrating as we have tried to set things up for weeks now and keep running into issues. Please advise on fix ASAP, as we need to go live.

    Hello Nora,

    Thank you for reaching out to us.

    If 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:


    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.


    I hope it helps,

    If you need some further assistance, please don't hesitate to contact us.

    Have a nice day!

    Kind Regards,
