Release Notes

makenotion/notion-sdk-js (@​notionhq/client)

v4.0.2

Compare Source

What's Changed

• Update Notion JS SDK with GetComment endpoint by @​julyou in #​595
  • Introduces notion.comments.retrieve({...}) endpoint to fetch a comment by its ID; this was previously a hidden and un-documented endpoint
  • Introduces API shape to manually refresh an API token by passing grant_type: "refresh_token" with a refresh_token to notion.oauth.token(...)
  • Minor refactors and additional type exports
• Bump TypeScript dependency to 5.9 by @​ksinder in #​597
  • WARNING: This might be effectively a breaking change in some cases since part of the SDK contract is exporting types for Notion's public API endpoints. Before upgrading, confirm your TypeScript version is sufficiently new or that the types are compatible with your system.

v4.0.0

Compare Source

What's Changed

• Remove no-op duplicates from union types across all endpoints by @​ksinder in #​579
• Remove legacy (<=2021) v1 API shape for page properties by @​ksinder in #​580
  • Removes support for the legacy (pre-Q3-2021) shape for page properties parameters from CreatePageBodyParameters and UpdatePageBodyParameters in src/api-endpoints.ts.
  • This collapses the union type of {old properties shape, new properties shape} down to the new shape only.
  • In the old shape, properties was a fairly ambiguous Record<string, ...> mapping each property key to the property value (a union type across all possible property types' values) e.g.

    {
      // ...
      "numberId": 24,
    }

  • In the new shape (the only one we want to support going forward), the value must be wrapped in an object that uses the polymorphic type pattern with the actual value defined in a sub-object to disambiguate:

    {
      // ...
      "numberId": {
        "type": "number",
        "number": 24
      }
    }

  • This matches up with our responses in the API read path so most, if not all, integrations are likely already using syntax compatible with the new shape
• chore: add JSDoc comments to API types by @​julyou in #​585
• Add support for attachments in Comment API by @​julyou in #​586
• CreatePage: support workspace-level private pages (+ misc param type refactors) by @​ksinder in #​587
  • No-op refactors/cleanups: extracting some components into separate type aliases, e.g. AnnotationRequest
  • Support the new mode in POST /v1/pages (CreatePage) API where:
    • parent can be omitted, or passed as {"workspace": true}, to create top-level private pages at the workspace level (for public integrations only)
    • properties is also optional. For standalone pages, this results in title defaulting to an empty string
• Sync API endpoints: add display_name to Comment, more extraction refactors and docstrings by @​ksinder in #​588
  • This includes miscellaneous extraction refactors for named subsets of parameters and other cleanups like new parameter docstrings.
  • The only functional change is adding the new display_name object to the CommentObjectResponse, and some fixes from previous PRs around parenthesizing a & (b | c) in allOf → oneOf OpenAPI types to get the correct result rather than defaulting to the incorrect interpretation (a & b) | c.
• Sync latest API endpoints schema as of 2025-06-30 by @​ksinder in #​590
  • Most of these are no-op re-ordering of type definitions.
  • Some added and edited comments/docstrings.
  • The only semantic change is adding support for the abc music language to LanguageRequest.

What's Changed

  • Refactor common parameter shapes into new types: InternalFileRequest, ExternalFileRequest, and InternalOrExternalFileWithNameRequest
  • Support commenting on a non-page block in the Create Comment API by accepting a parent type of block_id
• Use isomorphic fetch by @​sv2dev in #​506
  • This updates the minimum Node engine version from 12 to 18.
• Small typo fixes in docs and example files
  • docs: fix incorrect example path in README by @​R-jisu in #​556
  • Update .env.example by @​jtsmith1287 in #​532
