Can anyone provide an example of using Bridge HTTP Call Utility to Smartsheet Group?

I have a column of email addresses in multiple sheets and I would like to have an automated way to add them to a Smartsheet Group. This is for the dynamic view links we created to update the sheets. I was directed to use Smartsheet Bridge but I'm not too familiar with JSON. How I can PUT or POST a sheet column value in the Smartsheet Group URL? How can this be done?
