To practice subscribing to and accessing a product containing file-based data, see the [AWS Data Exchange Heartbeat](heartbeat.md).

## Step 1: Subscribing to a product containing the file-based data
<a name="subscribe-to-data-product"></a>

If you subscribe to a paid product, you are billed on your AWS bill. You get access to all entitled data sets. For more information, see [Subscribing to AWS Data Exchange data products on AWS Data Exchange](subscribe-to-data-sets.md).

**To subscribe to a product containing the file-based data**

1. Open and sign in to the [AWS Data Exchange console](https://console.aws.amazon.com/dataexchange).

1. In the left side navigation pane, under **Discover data products**, choose **Browse catalog**.

1. Under **Refine results**, use the **Data set type** filter and select **Files (Amazon S3 Objects)** to find products containing file-based data.

   For more information, see [Browse the catalog](subscriber-getting-started.md#browse-catalog).

1. Select a data product containing **Files (Amazon S3 Objects)**, and view its product detail page.

   The information on the product detail page includes a product description, the provider's contact information, and the details of the product's public offer. The public offer information includes price and durations, the data subscription agreement (DSA), and the refund policy. You can view the names of the data sets included in the product and the AWS Regions in which they are available. You can also continue to browse other product detail pages by choosing a product under **Similar products**.

   If the provider has issued a custom offer to your account (for example, a [private offer](subscribe-to-private-offer.md) or [Bring Your Own Subscription (BYOS) offer](subscribe-to-byos-offer.md)), you see those details, too.

1. In the top right corner, choose **Continue to subscribe**. 

1. Choose your preferred price and duration combination, choose whether to enable auto-renewal for the subscription, and review the offer details, including the DSA.
**Note**  
Some products require subscription verification. For more information, see [Subscription verification for subscribers in AWS Data Exchange](subscription-verification-sub.md).

1. Review the pricing information, choose the pricing offer, and then choose **Subscribe**.
**Note**  
If you subscribe to a paid product, you are prompted to confirm your decision to subscribe.

1. Under **Data sets included with your subscription**, view the listed **Data sets**.

   After the subscription finishes processing, you can choose a data set to access your entitled data or choose **View subscription** to view your subscription.

1. (*Optional*) For **Set up exports - *optional***, select the check boxes for the data sets that contain the revisions that you want to export. Selecting a data set will prepare its most recently published revision to be exported.

   1. Choose a **Simple** destination option to select an Amazon S3 bucket location or choose **Advanced** to configure an Amazon S3 key naming pattern. This choice determines where your revisions will be exported. For more information about using key patterns, see [Key patterns when exporting asset revisions from AWS Data Exchange](revision-export-keypatterns.md).

   1. For **Auto-export future revisions**, choose whether to turn on or turn off automatic revision export:
      + **On** – All future revisions will always be exported.
      + **Off** – Only one export of the most recent revision will be exported.

   1. Choose the **Encryption** options, and review the **Amazon S3 pricing**.
**Note**  
If you choose to export using AWS Key Management Service (AWS KMS) encryption, make sure your account has the correct AWS Identity and Access Management (IAM) permissions to create and revoke grants on the AWS KMS key you choose. Without these permissions, automatic export will fail.

   1. Choose **Export** to export the data to Amazon S3, or choose **Skip** if you prefer to wait and export or download later. For more information about how to export data after subscribing, see [(Optional) Exporting data](#export-data-after-subscribing).
**Note**  
It can take a few minutes for your subscription to become active after you choose **Subscribe**. If you choose **Export** before the subscription is active, you are prompted to wait until it is complete.  
After your subscription is active, your export will begin.  
Navigating away from this page prior to your subscription becoming active will not prevent the subscription from processing. It will prevent your data export from occurring.

## Step 2: Accessing a product containing file-based data

After you successfully subscribe to a product, you have access to the product data sets according to the terms of the data subscription agreement (DSA). 

The following topic describes how to access a product containing file-based data.

1. In the left navigation pane, choose **Subscriptions**, and then choose your product. 

1. View the data sets that are part of the product under **Entitled data sets**.

1. Choose a data set.

1. View the **Data set overview**, **Auto-export job destinations** (Amazon S3 products only), the **Revisions**, and the **Description** of the data set.

   For more information, see [Data in AWS Data Exchange](data-sets.md).

1. Choose a revision.

   Revisions are listed from latest to oldest.

   For information about exporting file-based assets, see [Exporting AWS Data Exchange assets to an S3 bucket as a subscriber (console)](export-asset-s3-console-sub.md).

### (Optional) Exporting data
<a name="export-data-after-subscribing"></a>

After your subscription is active, you can set up your Amazon S3 bucket to receive assets that you export. 

You can export the associated assets to Amazon S3 or you can use jobs with a signed URL.

If you want to export or download your data at a later time, including getting new revisions, see [Exporting AWS Data Exchange assets to an S3 bucket as a subscriber (console)](export-asset-s3-console-sub.md).

**Important**  
We recommend that you consider Amazon S3 security features when exporting data to Amazon S3. For more information about general guidelines and best practices, see [Security best practices for Amazon S3](https://docs.aws.amazon.com/AmazonS3/latest/dev/security-best-practices.html) in the *Amazon Simple Storage Service User Guide*.

For more information about how to export data, see [Exporting assets from AWS Data Exchange](exporting-assets.md) and [Exporting revisions from AWS Data Exchange](exporting-revisions.md).
