The Referral ID isn't stored directly in the database, it's generated dynamically based on each user's ID along with a few other unique parameters from UNA. To work around this, you could create a new field in the database specifically for storing this generated Referral ID for each member. Once stored, you can retrieve the Referral ID from this field whenever you need to send it to the third-party API. This approach would allow you to store and access the Referral ID more easily without relying on dynamic generation each time.
