Merge has introduced three new features—Advanced Mapping, Field Coverage, and Preview Values—to enhance its Field Mapping capabilities within its Unified API platform, aimed at simplifying the process of mapping custom data fields to its Common Models. Field Mapping allows users to add custom fields to Merge's models and map them to end-user applications, addressing the challenge of unaccounted custom data. Advanced Mapping assists users in selecting specific fields from complex objects using JMESPath queries, while Field Coverage helps identify the most frequently used remote fields by providing a coverage percentage. Preview Values allows users to verify the correctness of their mappings by displaying the mapped data in the Merge Dashboard, ensuring accurate data syncing. As Merge continues to expand its Common Models, the demand for Field Mapping may decrease, but the company aims to ensure that when needed, the feature remains efficient and user-friendly.
