The Fathom connector syncs meetings, summaries, transcripts, and team data from the Fathom AI notetaker into the PostHog data warehouse, so you can analyze meeting data alongside your product data.

## Prerequisites

A Fathom API key. Create one in Fathom under **User settings** > **API access**. The key reads meetings you recorded and meetings shared with you or your team. To sync the `users` table, you need a key that belongs to an account admin.

## Adding a data source

1.  In PostHog, go to the [Sources tab](https://app.posthog.com/data-management/sources) of the data pipeline section.
2.  Click **\+ New source** and click **Link** next to this source.
3.  Enter your credentials (see [Configuration](#configuration) below) and click **Next**.
4.  Select the tables you want to sync, choose a sync method and frequency, then click **Import**.

Once the syncs are complete, you can start querying this data in PostHog.

You'll be asked for:

-   **API key** – create an API key in Fathom under **User settings** > **API access** and paste it here.

## Sync modes

Each table can be synced in one of several modes, depending on what the source supports:

-   **Webhook** (when available) – the source pushes changes to PostHog in real time. Fastest freshness, lowest ongoing cost, and the only mode that reliably captures updates and deletes.
-   **Incremental** – only new or updated rows are synced on each run, using a cursor field (such as an `updated_at` timestamp). Cheaper than a full refresh, but deletes aren't captured.
-   **Append only** – new rows are appended using a cursor field; existing rows are never updated. Ideal for immutable, append-only tables like event logs.
-   **Full refresh** – the whole table is reloaded on every sync. Use it when a table has no reliable cursor or when you need deletions reflected.

See [sync methods](https://posthog.com/docs/data-pipelines/sources.md#sync-methods) for a full explanation of how each mode works and how to choose between them.

Some Fathom tables support **incremental** sync. Each incremental sync uses the `created_at` field to fetch only rows created since the last sync. Full refresh is also available for these tables.

| Table | Sync methods | Incremental field | Notes |
| --- | --- | --- | --- |
| `meetings` | Incremental sync, full refresh | `created_at` | Core meeting data with action items, highlights, and CRM matches |
| `meeting_summaries` | Incremental sync, full refresh | `created_at` | AI-generated summaries using the account's default template |
| `meeting_transcripts` | Incremental sync, full refresh | `created_at` | Full meeting transcripts |
| `meeting_types` | Full refresh | – | Meeting type definitions |
| `teams` | Full refresh | – | Organization teams |
| `team_members` | Full refresh | – | Team member details |
| `users` | Full refresh | – | User accounts and permissions (requires an admin API key) |

A full refresh sync replaces the contents of the table.

> **Note:** Summaries and transcripts are separate tables because Fathom rate-limits those requests more strictly than other endpoints. Keeping them separate avoids hitting rate limits during syncs.

## Configuration

| Option | Type | Required |
| --- | --- | --- |
| `API key` | password | Yes |

## Supported tables

| Table | Description | Sync method | Incremental field | Primary key |
| --- | --- | --- | --- | --- |
| `meetings` | A meeting that Fathom recorded, with its calendar details, attendees, action items, highlights and CRM matches. Only meetings the API key can view are included. | Incremental, Full refresh | created\_at | — |
| `meeting_summaries` | The summary of a Fathom meeting, made with the account's default summary template. | Incremental, Full refresh | created\_at | — |
| `meeting_transcripts` | The transcript of a Fathom meeting. | Incremental, Full refresh | created\_at | — |
| `meeting_types` | A meeting type of the organization. Inactive types can still be on older meetings. | Full refresh | — | — |
| `teams` | A team in the Fathom organization. | Full refresh | — | — |
| `team_members` | A member of a team in the Fathom organization. | Full refresh | — | — |
| `users` | A user in the Fathom account, with their permissions. Only an account admin's API key can read users. | Full refresh | — | — |

## Troubleshooting

-   If the connection fails with "Fathom rejected your API key", create a new key in Fathom under **User settings** > **API access** and try again.

-   If the `users` table returns a 403 error, the API key doesn't belong to an account admin. Use an admin's API key to sync users.

-   If syncs fail with a rate-limit error, wait a minute and try again. Fathom enforces strict rate limits, especially on summary and transcript requests.

If your sync is failing or data looks wrong, see the [Data warehouse troubleshooting guide](https://posthog.com/docs/data-warehouse/troubleshooting.md). If that doesn't help, [contact support](https://us.posthog.com/#panel=support%3Asupport%3Adata_warehouse%3A%3Atrue) – we're happy to help.
