# How to connect

> How to connect the Across ADN data source to Adriel: enter an Across ADN API Key, name the data source, and sync campaign and ad-group performance.

Across ADN is a Korean display ad network. Connecting it brings campaign and ad-group performance into Adriel dashboards, including impressions, clicks, click-attributed sales, and direct, indirect, and total conversions, broken down by date, campaign, and ad group.

## Before you connect

The following are required:

* An Across ADN account with API access enabled.
* The Across ADN **API Key** for that account. The key is sent on every API call as the `API-KEY` header, so anyone with the key can read the account's reports.
* Active campaigns and ad groups on Across ADN. Only data the API returns appears in dashboards.

## Connect Across ADN

<Steps>
  <Step title="Obtain the Across ADN API Key">
    Sign in to the Across ADN admin portal, locate the API access section, and copy the **API Key** for the account.
  </Step>

  <Step title="Find Across ADN in Adriel">
    On the Data Sources page, search for **Across ADN** and select it.
  </Step>

  <Step title="Enter the API Key and name">
    Paste the key into the **API Key** field, then enter a display **Name** for the data source. The name is shown in dashboards and connector lists.
  </Step>

  <Step title="Submit">
    Click **Submit** to complete the connection. The initial sync runs in the background; initial data availability can take up to one business day.
  </Step>
</Steps>

## What gets imported

The connector returns one row per date, campaign, and ad group, carrying the group-level metrics Across ADN provides: impressions, clicks, click-attributed sales, total conversions and value, and direct and indirect conversions and value. Data is broken down by date, campaign, and ad group, and Korean campaign and group names are preserved. Campaigns that return no groups produce no rows.

For the complete list of metrics, breakdowns, and refresh details, see the [Across ADN data reference](/data-sources/a-f/across-adn/data-reference).

## Troubleshooting

<AccordionGroup>
  <Accordion title="The connection fails immediately after submitting the API key">
    Verify the API Key was copied without leading or trailing whitespace. The key is sent as the `API-KEY` HTTP header on every API call, so any mistyped character causes authentication to fail.
  </Accordion>

  <Accordion title="New data does not appear right after a refresh">
    Refreshes are scheduled ten minutes after the Across ADN API availability windows open, so report data is not real-time. If a refresh appears delayed, wait for the next scheduled run.
  </Accordion>

  <Accordion title="A campaign is missing from reports">
    Confirm the campaign currently has at least one active ad group. The connector flattens the campaign-to-group hierarchy, so campaigns without any groups in the API response produce no rows.
  </Accordion>
</AccordionGroup>
