Let AI connect your sources for you

Skip the manual setup — run this in your project and the wizard auto-detects your databases and APIs and connects them to PostHog.

The Cohere connector syncs your LLM platform assets – datasets, connectors, models, fine-tuned models, and embed jobs – into the PostHog Data warehouse, so you can analyze your AI infrastructure alongside your product data.

## Prerequisites

You need a Cohere account with API access so you can create an API key.

## 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.

When linking Cohere, you'll need:

-   **API key** – find or create your key in the [Cohere dashboard](https://dashboard.cohere.com/api-keys).

## 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.

This source is full refresh only. Cohere does not expose reliable server-side timestamp filters across its endpoints, and the synced entities are small and mutable (statuses and timestamps change in place), so full refresh ensures no updates are missed.

## Configuration

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

## Supported tables

| Table | Description | Sync method | Incremental field | Primary key |
| --- | --- | --- | --- | --- |
| `datasets` | A dataset uploaded to Cohere for fine-tuning or embedding jobs. | Full refresh | — | — |
| `models` | A model available to your account in the Cohere model catalog. | Full refresh | — | — |
| `embed_jobs` | An asynchronous job that embeds a dataset into vectors. | Full refresh | — | — |
| `batches` | A batch job that runs an uploaded dataset of requests through a model. | Full refresh | — | — |

## Troubleshooting

-   If you see an authentication error, your Cohere API key may be invalid or revoked. Create a new key in the [Cohere dashboard](https://dashboard.cohere.com/api-keys), then reconnect.

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.
