Which native platform field feeds each unified field, for the metrics people compare most across platforms.

Each platform names the same number its own way: TikTok says play_count, YouTube says viewCount, Twitter/X says views.count. In a response, all three arrive as post.engagement.views. The tables below show, per platform, which native fields a unified field is filled from.

Build comparisons on the unified field once and they work across every platform listed. Several native names per platform means different endpoints on that platform expose the value under different names.
