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 Adyen connector syncs account holders, balance accounts, companies, and more into the PostHog data warehouse, so you can analyze them alongside your product data.

## Prerequisites

Credentials that can read the data you want to sync. PostHog only reads data, so read access is enough.

## 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.

Connect your Adyen account to sync payments data.

Create an API credential in your Adyen Customer Area under **Developers > API credentials**, then paste its API key below. Which tables you can sync depends on what that credential can reach:

-   **Transactions, transfers, account holders, balance accounts and payment instruments** need an Adyen for Platforms or Adyen Issuing integration. Add your balance platform ID too.
-   **Legal entities** also need the balance platform ID, plus a Legal Entity Management API role on the credential.
-   **Settlement detail reports** need a merchant account and the **Merchant Report Download** role. Adyen only creates these files once you turn on the settlement details report in your Customer Area.
-   **Companies, merchant accounts and stores** come from the Management API and need an account read role.

Pick the environment that matches where you created the API key - a test key won't work against live.

You'll be asked for:

-   **Environment**: choose between Live and Test.
-   **API key**

## 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.

All Adyen tables are full refresh. Each sync replaces the contents of the table.

## Configuration

## Supported tables

| `MerchantAccounts` | Merchant accounts your API credential can access, with their processing configuration. | Full refresh | — | — |
| `Stores` | Physical store locations across the merchant accounts your API credential can access. | Full refresh | — | — |
| `SettlementDetailReports` | Transaction-level settlement lines from the settlement details report, one row per settled payment or fee. | Incremental, Full refresh | batch\_number | — |
| `Transactions` | Individual movements of funds booked against a balance account. | Incremental, Full refresh | creationDate | — |
| `Transfers` | Transfer instructions such as payouts, top-ups and internal transfers. | Incremental, Full refresh | createdAt | — |

## Troubleshooting

-   If the connection fails with an authorization error, the API key is wrong, expired, or has been revoked. Create a new one, then reconnect the source.
-   If a table syncs no rows, the credential may not have access to that data. Check its permissions, then reconnect the source.

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.
