can we plug one into bowen.mysculpt.net Isaac  please? 

the homepage

whitney.zelig@gmail.com - OK. Will check. We may need some credentials from the client.

it will be on bowen.mysculpt.net Isaac we have access..

or do you mean GMB credentials?

whitney.zelig@gmail.com - I was referring to GMB. But it wouldn't be required.

I have now installed and set up the plugin on the website.
https://bowen.mysculpt.net/

The client can register for a free account from here - https://www.trustindex.io/ and this plugin will automatically fetch the latest google review. The free version which I have installed will require someone to manually click on the download button every week to fetch the latest reviews.

Hey Isaac can you explain this to the client and copy me on it?

Not sure i understand it myself. 

whitney.zelig@gmail.com - Sure. Will do that.
