POST https://api.synup.com/api/v4/locations/review-campaigns/customers
```

This API adds new customers to an existing review campaign, allowing them to receive review requests.

**Behavior:**
- Supports batch addition of multiple customers in a single request.
- Customers will receive review requests via the configured delivery method (email, SMS, or both).
- Ensures duplicate entries are not added to the same campaign.
