How to award a customer with 'gift' points that they can use for their first order?

This rule will allow the customer to receive points upon registration, which can be used in their first order.

Customers can receive points immediately after registering by using a Behaviour rule. Here’s how:

• Create a Behaviour rule in Reward Points -> Earning points and in the Conditions & Actions tab, select the Customer signs up in-store event;
• Set Customer Earning Style to Give X points to customer and specify the number of points to be awarded;
• Add any other necessary conditions, such as checking for referees (see the case above);
• Save and activate the rule.
