Updating Connected IDs on TMDB

TMDB allows editors to link titles with external databases such as IMDb, TVDB, and Wikidata ensuring proper synchronization and data accuracy across multiple services like SIMKL.

These external links (called Connected IDs) are essential for metadata exchange and for keeping related movie and TV entries correctly associated across platforms.

For TV Shows

When editing a TV show, an additional field appears under “Other Databases” for: TVDB ID: connects TMDB entries with TheTVDB’s corresponding listing.

This field is especially important for synchronization tools (like SIMKL, Plex) that use both databases to match TV episodes.
