How to require approval for ambassadors?

Go to the app inside of your Shopify admin. 

Click on the "Settings" tab.

Then check the box that says "Require approval for ambassador applications".

Scroll to the bottom and hit save: 

Now when new ambassadors sign up on your portal, they will be shown in the ambassador's tab under "Pending applications". 

Pending ambassadors will not be able to create a discount code without approval. 

You can select Approve or Reject for each pending application.
