ID is a crucial item for recommendation campaigns. You need to use an ID for your recommendation area during the integration process. Each recommendation campaign works with this specific ID.
For example, if you want to display recommended items on your home page, you should give one of the IDs in the panel (from 1 to 10). Let's say you give 1 as the ID. All changes in the campaign with ID 1 will affect your home page recommendations.
The application should handle all these. Our SDK only provides communication with the recommendation engine.
Once the integration is completed, you can configure your Smart Recommender campaigns from your mobile panel.
You can access Smart Recommender through Campaigns > Recommendation > App Smart Recommender. 10 predefined campaigns are available, listed by name, recommendation strategy, status, and last updated date. You can edit these existing campaigns.
