When you have set up the Stamps settings and the defaults, you need to add its rule to start it in your app. Follow the steps below.
1. Admin > Content > Customize. Click to edit the app.
2. Advanced > Manage Rule.
3. The rule that you created earlier, is displayed. When the below screen comes up, move to the 'Rules' and select a rule or click on '+New Rule' (or + Add link inside an already added Rule).
Optional rules: When you want users to meet with any one of two or more rules, example pay through PayPal or with Cash
Combined rules: When you want users to meet with all of the selected rules to proceed. Example, pay 'Cash' and 'Address' is needed
How? Click on the '+ New Rule' button to add as 'optional' Click on the '+ Add' button to add as 'combined' (while there is already a rule)
4. Click on the +New rule and click on 'Pay with Stamps' as your rule.
Depending on the plugins you have subscribed to, or installed, you might see more rules.
5. 'Save' the rule.
6. Click on the 'Back' button, and in the main content screen, click 'Put online' to publish your changes on users' devices. The button's caption changes from 'Put online' to 'Published' once the changes have been applied successfully.
