This API grants multiple cart promotions to a customer in a single request.

When you call this API, the system immediately adds all specified promotions to the customer's wallet, making them available for redemption.
Use this API when you need to award several promotions to a customer at once, such as during a batch processing operation or as part of a loyalty program milestone.
You can specify different earn counts for each promotion in the earnedPromotions array to control how many times each promotion is granted.
To earn a single promotion for a customer, use the Earn Cart Promotion API instead.
