How to find the Group ID
The Group ID is a unique number assigned to each individual group that you have created.
A Group ID is required when you are setting up a sign up form on your website or setting up a sign up form on your Facebook page. Having the correct ID number will ensure all contacts who sign up using the form are placed into the correct group in the Contacts area.
The Group ID can be found in the Group Card. To view the Group Card, start by clicking on the 3 dots next to the Group you need the ID from.
When you click Edit the Edit Group screen will open up and you can see what the Group ID is as well a clipboard symbol next to it that will automatically copy the ID for you.
