# Creating an AppMetrica connection in Yandex DataLens

To create an AppMetrica connection:


1. Open the [connection creation page](https://datalens.ru/connections/new).
1. Under **Files and services**, select the **AppMetrica** connection.
1. Configure the connection as follows:

   * **OAuth token**: Click **Get token** or enter the [OAuth token](#get-oauth-token) manually to access the AppMetrica data.
   * **App**: Specify one or more applications to connect to.
   * **Accuracy**: Set the data accuracy (sampling rate). You can change the accuracy after you create the connection.

     {% note info %}
     
     If you want to get access for a username other than your current Yandex account or there is no relevant tag in the list, see [Getting an OAuth token](#get-oauth-token).
     
     You cannot connect multiple tag from different accounts at the same time.
     
     {% endnote %}


1. Leave the **Automatically create dashboard, charts, and dataset on connection** option enabled if you need a folder with a standard set of datasets and charts and a ready-made dashboard.


1. Click **Create connection**.


1. Select the [workbook](../../workbooks-collections/index.md) to save your connection to or create a new one. If using legacy folder navigation, select a folder to save the connection to. Click **Create**.


1. Enter a name for the connection and click **Create**.

{% note info %}

* By default, AppMetrica data is exported for the last 60 days. If you add a filter by date to the chart, the AppMetrica filter will be reset. We recommend adding a filter by date as an offset relative to the current date.
* On the AppMetrica side, there is a quota of three concurrent requests per API key.

{% endnote %}

For datasets based on AppMetrica connections, the following groups of metrics are available:

- Installations
- Audience
- Client events
- Push campaigns
- Audience + social demographics 


Connections to AppMetrica do not support [public access](../../concepts/datalens-public.md) to objects created on top of it. To share a dashboard or chart created based on this connection, use one of the following methods:

* [Add](../../security/add-new-user.md) a user to your organization or cloud and grant them access to a dashboard or chart.
* [Export](../../qa/connections.md#uploading-data-logs-api) data to a [Managed Service for ClickHouse®](../../../managed-clickhouse/index.md) cluster and use a connection to the ClickHouse® database as a source. To learn more about the Managed Service for ClickHouse® pricing plans, see [Pricing](../../../managed-clickhouse/pricing.md).


## Getting an OAuth token {#get-oauth-token}

You can specify an OAuth token of any Yandex account.

To get access to a Yandex Metrica tag of a username other than your current Yandex account, follow these steps:
1. Switch to an account that has access to Yandex Metrica.
1. Get a token [here](https://oauth.yandex.com/authorize?response_type=token&client_id=4f802221a95340dd9417c04bc30606b5). If required, allow access to the application, then copy the token.
1. Switch to an account that has access to Yandex DataLens.
1. Create a new connection to Yandex Metrica and paste the obtained token from the clipboard to the **OAuth token** field.
