When setting up competitions or achievements in CompetitionLabs, meta data about the products and members in CompetitionLabs helps staff by showing product and member details in terms they are familiar with, rather than by Id. Look-up services populate your Space with meta data information about the product or member in our system.
This service requests meta data from a member specific endpoint that you implement. The endpoint should accept the member reference id that you send as part of your event stream and return meta data in JSON format you want to associate with that Member. For example the information returned could be – public display name, country code, currency code or other existing segments for that member.
