Extensions API Home Getting Started Guide Dashboard Interface Worksheet Interface Filter Interface Parameter Interface TableauEventType Enum

What it is: Server-side API that lets Tableau calculated fields call Python/R scripts via SCRIPT_REAL(), SCRIPT_STR(), etc.

Relevance: Not directly usable from a Dashboard Extension (no client API). Useful only if embedding Tableau views that already use TabPy calculations.

What it is: Web Component API (<tableau-viz>) for embedding Tableau views in external web pages. Uses OAuth/token-based auth.

Can we use it inside an Extension? Likely blocked — Tableau's webview would be embedding itself recursively. Use the Extensions API instead.

Embedding API v3 Docs →

What it is: Server admin API for workbooks, users, data sources, permissions. Requires server credentials.

Relevance for extensions: Could call the REST API via fetch() IF CORS allows it and you have credentials. Useful for: listing workbooks, getting view thumbnails, metadata queries.

Tableau Cloud REST API: Requires Personal Access Token or OAuth. Available from Tableau Public only for read operations.

What it is: A different API for creating custom chart types that appear as viz marks inside Tableau worksheets (not a dashboard panel). Uses a different TREX manifest type.

Key difference: Viz extensions live inside worksheets; Dashboard extensions live in dashboard zones. They have separate APIs.

Viz extension APIs: getDataAsync(), updateMarkAsync(), registerSelectedMarksCallback() — completely different from dashboard extensions.
