Trouble Connecting Your Google Account? Here's Why You Might See a 403 Error

Why am I getting a 403 error when trying to connect my Google account?

If you're trying to connect your Google account to Cowlendar and see the message Error 403: disallowed_useragent, this can be resolved quickly.

This issue occurs when the Google login flow is opened from a webview (a built-in browser within the Shopify app) instead of a secure browser like Chrome or Safari. Google blocks these types of connections for security reasons.

Since Cowlendar does not have a native mobile app and works as a web app, the connection must happen in a standalone browser.

How to Fix It

To complete the connection, open Cowlendar from a laptop or desktop computer using a browser like Chrome, Safari, or Firefox. Once the Google account is successfully linked, you can return to using Cowlendar from any device without issues.
