5. Test Embed Configuration
Pre-Deployment testing options
Before integrating Embed you might want to check that all the settings are correct and the iframe looks as expected for an end user.
Local testing
In order to open an Embed in a local html page (i.e. where the URL is a file path), you need to specify file://* in the allowed domains.
Testing on Google Sites
One can also test embedding the iframe in Google Sites. In order to allow it to open there the allowed domains need to be set to:
The allowed domains settings above should be used solely during the testing phase, where it's absolutely needed.
Remove it from the allowed domains once you're going to your staging or production environment as it adds a potential security risk.
