If you don't have the option to embed the Usersnap widget to your site, the Usersnap browser extensions are the solution. You can annotate on your website without changing your template code. We have an extension available for Google Chrome and Firefox.
Google Chrome Extension
Google Chrome users find the extension in the Chrome Store: Google Chrome Store.
After the installation, click on the Usersnap icon in your toolbar and copy the API key from your project settings into the Usersnap extension settings.
Firefox users find the add-on in the add-ons directory for Firefox: Firefox Add-On.
After the installation, click on the Usersnap icon in your toolbar and copy the API key from your project settings into the Usersnap add-on settings.
Change your API Key
If you want to change your existing API key, open the settings dashboard and choose Add-ons.
Under the section Extensions you will find your Usersnap Add-on, where you can open the preferences.
Simply exchange your existing API key with your new API key.
