Summary

Migrates the Grain integration from the legacy v1 public API to the v2 public API (https://api.grain.com/_/public-api/v2, required Public-Api-Version: 2025-10-31 header). Grain's v1 API is deprecated and will be sunset. See the documentation.

Auth is unchanged — Grain's OAuth endpoints are unversioned and v2 accepts the same bearer tokens, so existing connected accounts continue to work without any app-config changes.

Changes

  • grain.app.mjs: new v2 base URL and version header; list/get recording moved to v2 POST endpoints with filter/include bodies; webhook creation moved to POST /hooks/create with hook_type (the v1 views resource no longer exists in v2); shared propDefinitions for the recording include options.
  • Get Recording (1.0.0, major — props removed/renamed): v1 transcript_format/intelligence_notes_format/allowed_intelligence_notes props replaced with v2 include options (highlights, participants, AI action items, AI summary, calendar event, HubSpot data, screenshares).
  • New Recording (Instant) (1.0.0, major — viewId prop removed): subscribes via hook_type: recording_added with optional include props; test event updated to the v2 payload. Also guards deactivate() when no hook ID was stored, and emits the recording's native ID for stable deduplication.
  • New actions:
    • Get Transcript (0.0.1): fetches a recording's transcript in json, txt, vtt, or srt format.
    • List Recordings (0.0.1): lists recordings with v2 filters (date range, title search, participant scope) and cursor pagination.
  • Removed sources: the updated/removed recording, highlight, and story sources are deleted — they were built on the v1 views-based webhook model. Existing deployed instances remain pinned to their published versions and are unaffected.
  • components/grain/package.json bumped 0.1.01.0.0 (major, matching the largest component change).

Summary by CodeRabbit

  • New Features

    • Added optional highlights, participants, AI insights, calendar, HubSpot, and screenshare data when retrieving recordings.
    • Added Grain Public API v2 support and richer recording-created events.
  • Changes

    • Updated transcript format options to include Text and SRT.
    • Renamed the recording identifier field to recordingId.

…s actions

Migrate all components from the legacy v1 public API to v2
(api.grain.com/_/public-api/v2, Public-Api-Version: 2025-10-31):

- Get Recording: replace transcript/intelligence-notes format props with
  v2 include options (highlights, participants, AI action items, AI
  summary, calendar event, HubSpot, screenshares); major bump to 1.0.0
- New Recording (Instant): subscribe via v2 hook_type instead of the
  removed views resource, add include props; major bump to 1.0.0
- Remove the eight other sources (updated/removed recordings, highlights,
  stories) — existing deployments stay pinned to their published versions
- Add Get Transcript action (json/txt/vtt/srt formats)
- Add List Recordings action with v2 recording filters
- Guard webhook deactivate when no hook ID is stored; emit native
  recording ID for stable dedupe

📝 Walkthrough

Walkthrough

The Grain integration now targets Public API v2. It adds recording listing and transcript actions, updates recording retrieval and webhook handling, revises recording-added events, and removes story and highlight instant sources.

Changes

Grain API v2 integration

Layer / File(s) Summary
Public API v2 app contracts
components/grain/grain.app.mjs, components/grain/package.json
The app uses the 2025-10-31 API version, renamed recordingId, recording inclusion flags, POST recording requests, transcript retrieval, and /hooks/create. The package version is 1.0.0.
Recording retrieval and listing actions
components/grain/actions/get-recording/get-recording.mjs, components/grain/actions/get-transcript/get-transcript.mjs, components/grain/actions/list-recordings/list-recordings.mjs, components/grain/common/*
Recording retrieval sends truthy include flags. New actions retrieve transcripts and paginate filtered recording lists. Transcript formats include txt, vtt, and srt. The unused parseObject helper is removed.
Recording webhook source flow
components/grain/sources/common/base.mjs, components/grain/sources/new-recording-instant/*
Webhook creation uses hook_type and include. Recording-added events no longer use view filters and emit the source data ID with a current timestamp. The recording fixture contains the updated payload shape.
Retired instant sources and fixtures
components/grain/sources/new-highlight-instant/*, components/grain/sources/new-story-instant/*, components/grain/sources/removed-highlight-instant/*, components/grain/sources/removed-recording-instant/*, components/grain/sources/removed-story-instant/*, components/grain/sources/updated-highlight-instant/*, components/grain/sources/updated-recording-instant/*, components/grain/sources/updated-story-instant/*
The listed story, highlight, and recording instant sources and their event fixtures are removed.

For get-recording, reference List Recordings for obtaining the recording ID and

format-dependent output, and obtaining the recording ID; for list-recordings,
explain its role in finding IDs for Get Recording and Get Transcript plus
filtering, pagination, and maxResults behavior.

- Line 45: Update the maxResults schema definition to include a minimum value of
1 and document that only positive integer values are valid, preventing invalid
values from reaching the recordings length assignment.

In `@components/grain/grain.app.mjs`:
- Line 11: Update the options method’s prevContext destructuring to default
prevContext to an empty object before reading nextPage, ensuring the initial
recordingId.options() call loads the first page when no previous context is
provided.

In `@components/grain/sources/common/base.mjs`:
- Line 41: Update the emitted event metadata timestamp at the ts field to use
body.data.end_datetime, falling back to Date.now() only when that API timestamp
is unavailable.
