# How to connect

> How to connect the LINE Ads data source to Adriel: retrieve the Group ID and API keys, sign in with the access and secret keys, and select an ad account.

LINE Ads is the advertising platform of LINE, the messaging app operated by LY Corporation that is dominant in Japan, Taiwan, and Thailand. Connecting it brings campaign performance across LINE feed, chat, discovery, and LINE-internal placements such as Sponsored Stickers and LINE Friends ads into Adriel dashboards, with metrics, breakdowns, and currencies normalized alongside other channels.

## Before you connect

The following are required:

* A LINE Ads account.
* The LINE Ads Group ID for the group to connect (format `G00000000000`).
* API access enabled for the relevant Group. Contact the LINE account manager to activate this feature.
* The API access key for the Group.
* The API secret key for the Group.

## Connect LINE Ads

<Steps>
  <Step title="Retrieve the Group ID and API keys from LINE Ads">
    Log in to the LINE Ads account and open the **Groups** tab next to the **Home** tab. Copy the Group ID (format `G00000000000`). Click the group name in the list to open its page, then open **Menu** in the upper-left corner and go to **Settings** > **Group settings**. Copy the **API access key** and **API secret key** and save them in a secure location. If the secret key is not visible, click **Regenerate your API secret key**. Contact the LINE account manager if the API keys cannot be generated or enabled.
  </Step>

  <Step title="Enter the connection credentials">
    On the **Data Sources** page, search for **LINE Ads** and select it. Under **Connection Settings**, fill in the two required fields, then click **Submit** to proceed.

    * **Access key**: the access key retrieved from LINE Ads.
    * **Secret key**: the secret key retrieved from LINE Ads.
  </Step>

  <Step title="Select the group and ad account">
    Under **Data Source Settings**, fill in the two required fields.

    * **Group ID**: the Group ID retrieved from LINE Ads, in the format `G00000000000`.
    * **Ad Account**: select an ad account from the dropdown shown once the Group ID is filled in successfully.
  </Step>

  <Step title="Submit">
    Click **Submit** to complete the connection. Initial data availability can take up to one business day.
  </Step>
</Steps>

## What gets imported

The connector imports the campaign hierarchy (ad account → campaign → ad set → ad), daily performance metrics (spend, impressions, clicks, and derived rates), conversion metrics, and LINE-specific engagement metrics such as friend additions from Sponsored Stickers and LINE Friends ads. Demographic breakdowns by OS, age, gender, and location are available at the ad account level.

For the complete list of metrics, breakdowns, and limits, see the [LINE Ads data reference](/data-sources/g-n/line-ads/data-reference).

## Troubleshooting

<AccordionGroup>
  <Accordion title="Dashboard data lags the LINE Ads UI">
    Report data is cache-only and refreshes twice daily, at 10:00 PM UTC and 7:00 AM UTC. Live data is not fetched on dashboard load, so recent activity in the LINE Ads UI may not appear until the next scheduled refresh.
  </Accordion>

  <Accordion title="Authentication failure after credential rotation">
    Signed requests use the stored access key and secret key. If the secret key is regenerated in the LINE Business admin console, the connection must be re-established with the new credential.
  </Accordion>

  <Accordion title="OS, age, gender, or location breakdowns missing at lower levels">
    These breakdowns are returned by the LINE Business API only at the ad account level. Splitting them by campaign, ad set, or ad is not supported.
  </Accordion>

  <Accordion title="Older campaigns are not available">
    The initial backfill covers the last 730 days. Campaigns and reports outside this window are not imported.
  </Accordion>
