> Prepare your ALTR environment and generate API credentials for Atlan integration.

Prepare your ALTR environment so Atlan can import ALTR classification metadata.

## Permissions required

Before you begin, make sure you have:

* Access to an ALTR account
* Permission in ALTR to manage data sources, run classifications, and generate API credentials
* A data source that's present in both ALTR and Atlan

## Supported data sources

ALTR classification is supported for these sources:

| Data source | Type |
| --- | --- |
| [Snowflake](https://docs.atlan.com/llms/connectors/snowflake/llms.txt) | Cloud data warehouse |
| [Databricks](https://docs.atlan.com/llms/connectors/databricks/llms.txt) | Cloud data warehouse |
| [PostgreSQL](https://docs.atlan.com/llms/connectors/postgresql/llms.txt) | Database |
| [Microsoft SQL Server](https://docs.atlan.com/llms/connectors/microsoft-sql-server/llms.txt) | Database |
| [Oracle](https://docs.atlan.com/llms/connectors/oracle/llms.txt) | Database |
| [MySQL](https://docs.atlan.com/llms/connectors/mysql/llms.txt) | Database |

## Prepare ALTR environment

For source-side setup, follow the ALTR documentation:

1. Create and set up your ALTR account: [Create and set up an ALTR account](https://docs.altr.com/en/create-and-set-up-an-altr-account.html)
2. Configure your data source in ALTR: [Data source management](https://docs.altr.com/en/data-source-management.html)
3. Run a classification job in ALTR: [Data classification report](https://docs.altr.com/en/data-classification.html#classify-data)
4. Confirm the same data source is crawled in Atlan so asset mapping works, using the matching [Atlan connector](#supported-data-sources).

## Create API credentials in ALTR

[Create an API key and API secret in ALTR](https://docs.altr.com/en/manage-api-keys.html) for the Atlan integration, then save both values for workflow configuration in Atlan.
