Not able to test PDF embedded

So I have all the credentials and the domain set up and then I copied and pasted the code provided in the documentation into an index.html file in a subfolder of my website. This is all done locally using Dreamweaver.

I get the following message both in live mode and also when viewing locally on a browser.

File preview not available

The application domain (file://) is not authorised to use the provided PDF Embedd API Client ID.

Now I do understand why this is the case but your documentation states that this should still work.

I then added my client ID but this still did not work.

So how do I make this work to edit and view locally then what do I do differently to allow me to go live.

Your instructions are not very clear.

Thank you.
