We rebuilt the lists experience: a faster UI, a more powerful data model, and a new API underneath. Everything you tracked in legacy lists is still here — this guide walks you through what's different and what's now possible.
For API users: New Lists are backed by the new Graphql v2 API. Most integrations don't need to change, but if you use the legacy watchlist or custom-field APIs, you'll need to migrate before November 5, 2026. Learn more here or go to the docs here.
Rolling out in phases
New lists are rolling out gradually over the coming months. Customers will be moved over in cohorts, not all at once. We'll let you know when your account is scheduled to move.
What happens when you move: your data migrates automatically. Companies, people, list membership, custom fields, and views all carry over, so there's nothing you need to do to prepare.
What happens to legacy lists: once all customers have moved to New Lists, legacy lists will be deprecated and eventually deleted. We are planning to do this by November 5, 2026.
🗺️ What's changed at a glance
In legacy lists | In new Lists |
Company / People watchlist | List — one unified model for companies and people |
Watchlist member | List entry — a record's membership in a list |
Custom field (per list) | List-specific field — lives on one list |
Global custom field | Global field — travels with the record everywhere |
Saved view | Named view — one saved layout of filters, sorts, and columns |
Named views now also support drafts (adjust without affecting teammates), favorites, and defaults.
🤖 Built for AI workflows
New Lists work natively with Harmonic's AI tools.
Scout can read from and write to your lists and views — ask it to fill in fields, triage entries, or build a view.
The underlying v2 API is fully introspectable, so AI agents (Claude, Cursor, and others) can discover the schema and work with your lists automatically.
📊 Backed by a more powerful data model
The biggest shift: your workspace is now a shared dataset, not just a collection of separate lists.
All Companies and All People give you a workspace-wide view of every record your team tracks — every company or person that's in any list, in one place. These views support the same filtering, bulk edit, and field tools as any other list.
Records vs. entries. A company or person is a record; it can appear in many lists at once. Each appearance is an entry. Record-level data is shared everywhere; entry-level data belongs to one list.
Global fields are attached to the record itself
List-specific fields capture workflow context that only makes sense in one list
New field types: Currency, Percent, Email, Long Text, URL Lists, Text Lists, and User references — alongside the text, number, date, select, and checkbox types you already use.
💡 Rule of thumb: if a value should be the same everywhere a company appears, make it a global field. If it's specific to one list or workflow, make it a list-specific field.

Live updates. Edits from teammates appear automatically, no refresh needed.
Favorite views for one-click access to your most-used workflows
Searchable Team Network — search and filter your team's collective network to find the right warm introduction
🛠️ For developers: Workspace in the v2 API
New Lists are powered by the Workspace surface of Harmonic's v2 API — the same single GraphQL endpoint (api.harmonic.ai/graphql/v2) that serves all v2 queries. Workspace covers lists, records, fields, views, and imports.
One model, less code. Company and people lists share a single
listtype — no more parallel company-vs-people code paths.Fetch exactly what you need. Request just the fields and values you want in one round trip.
Bulk by default. Imports resolve entities by website, LinkedIn, or email and create missing records in a single job.
Introspectable schema. Coding agents can explore and validate every call against the live schema.
Note: the legacy watchlist and custom-field APIs support both REST and GraphQL. Workspace is GraphQL only, there's no REST equivalent. If your integration calls the legacy REST endpoints, migrating means rewriting those calls in GraphQL, not just pointing to a new URL.
Do you need to migrate? Only if you use the legacy watchlist and custom-field APIs, which will no longer be available in November 5, 2026. All other v1 APIs (enrichment, company/people data, search) are fully forward-compatible on v2 — your existing queries work as-is on the /graphql/v2 endpoint with no forced migration. If you do use the legacy watchlist APIs, nothing changes for your account until you schedule a migration with us — see the migration guide in our API docs, or email support@harmonic.ai to coordinate.
