feat(grain): migrate to v2 API, add get-transcript and list-recordings actions - #21865
Conversation
…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
- Default prevContext safely in recordingId options loader - Add min: 1 constraint to maxResults in list-recordings - Use recording end_datetime for emitted event timestamp, falling back to Date.now() when unavailable - Expand action descriptions with agent guidance and cross-tool references

Thanks @michelle0927, I've added those secondary hook types and updated the links you referenced |
Grain's hook registration sends a probe request before marking a webhook active; without an explicit response the interface never acknowledges it. Switch http to customResponse and respond 200 immediately on receipt.

…highlight timestamps Concatenate resource ID + payload-derived timestamp for *_updated events so retries of the same update share an ID while a later, distinct update gets a new one, instead of reusing the bare resource ID or Date.now(). Hoist the recording/highlight getTimestamp overrides (end_datetime / created_datetime) into their shared common modules so updated-recording-instant and updated-highlight-instant get accurate payload timestamps too, instead of falling back to receipt time.

Summary
Migrates the Grain integration from the deprecated v1 API to the Grain Public API v2, while retaining all nine existing recording, highlight, and story triggers.
Requests use
https://api.grain.com/_/public-api/v2withPublic-Api-Version: 2025-10-31. OAuth authentication is unchanged.Changes
1.0.0): replaces the legacy transcript and intelligence-note props with v2 include options for highlights, participants, AI action items, AI summary, calendar events, HubSpot data, and screenshares.0.0.1): retrieves transcripts as JSON, text, VTT, or SRT. JSON uses/recordings/:id/transcript; text formats use the corresponding file extension.0.0.1): supports date, title, and participant-scope filters, follows pagination cursors, and returns up to the configured maximum.1.0.0): migrate from view-based subscriptions toPOST /hooks/createusing the v2 hook types below. Existing component keys are retained, including the “Removed” sources, which subscribe to*_deleted.recording_added,recording_updated,recording_deletedhighlight_added,highlight_updated,highlight_deletedstory_added,story_updated,story_deletedRecording added/updated sources share optional recording include props; highlight added/updated sources support transcript and speaker includes. Story and deletion subscriptions omit include options. Shared prop definitions live in the app file, and common source modules reuse their configuration and request logic.
Webhook handling ignores reachability probes and mismatched event types, stores subscription IDs for cleanup, and safely handles deactivation when registration did not complete. Added events use resource timestamps when available; story updates use
last_edited_datetimewhen present, with receipt-time fallbacks.Compatibility and delivery behavior
viewIdis removed from sources, and Get Recording's legacy props are removed or renamed. Existing deployed versions remain pinned until upgraded.0.1.0to1.0.0, matching the breaking component changes.Validation
