The Qonto connector syncs your business banking data into the PostHog data warehouse, so you can analyze transactions, transfers, and account activity alongside your product data.

[Qonto](https://qonto.com) is a European business finance platform. This source syncs bank accounts, transactions, labels, memberships, and SEPA transfers. The `transactions` and `transfers` tables support incremental sync using the `updated_at` field, so only new or updated rows are fetched after the initial sync.

## Prerequisites

You need a Qonto account with API access. You can find your credentials in the Qonto dashboard under **Integrations and Partnerships** > **API key**. You'll need your **organization login** and **secret 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 Qonto, you'll need:

-   **Organization login** – your Qonto organization login, found in your Qonto dashboard under **Integrations and Partnerships** > **API key**.
-   **Secret key** – your Qonto API secret key, found on the same page.

## 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](/docs/cdp/sources.md#sync-methods) for a full explanation of how each mode works and how to choose between them.

## Configuration

| Option | Type | Required |
| --- | --- | --- |
| `Organization login` | text | Yes |
| `Secret key` | password | Yes |

## Supported tables

| Table | Description | Sync method | Incremental field | Primary key |
| --- | --- | --- | --- | --- |
| `bank_accounts` | Qonto bank accounts for the authenticated organization, including balances and account details. | Full refresh | — | — |
| `transactions` | Transactions across Qonto bank accounts, including pending, declined, completed, and reversed transactions. | Incremental, Full refresh | updated\_at | — |
| `labels` | Labels that classify transactions for the authenticated organization. | Full refresh | — | — |
| `memberships` | Users with access to the organization's Qonto account. | Full refresh | — | — |
| `transfers` | SEPA transfers for the authenticated organization. | Incremental, Full refresh | updated\_at | — |

## Troubleshooting

-   If you see an authentication error, your organization login or secret key is invalid or has been revoked. Generate a new API key in your Qonto dashboard under **Integrations and Partnerships** > **API key**, then reconnect.
-   If you see a permissions error, the API key does not have permission to read this data. Check the key's permissions in your Qonto dashboard.
-   This source only syncs accounts owned by your organization. Connected external accounts are excluded.

If your sync is failing or data looks wrong, see the [Data warehouse troubleshooting guide](/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.
