Overview

The data export feature provides the capability to bulk export your CleverTap event data to your AWS S3 bucket. You can use this for analysis in BI tools or storage in your data warehouse for analysis in the future.

Setup

The following are the two major steps involved in enabling this feature for your account:

1. Create an AWS S3 Bucket.
2. Configure Buckets details on the CleverTap Dashboard using one of the following methods:
   • Using Access Key
   • Using IAM Policy

Create an AWS S3 Bucket

To create an AWS S3 bucket:

1. Log in to your AWS account, then search for S3 in the AWS services box.
2. Select S3 from the search results.

On clicking, the Bucket page displays.

3. Click Create bucket. On clicking, the Create bucket page displays:

4. Enter a bucket name, region, logging, versioning, and encryption preferences.

Recommendation for Setup

For this integration, you need not modify the default settings; however, you must check your internal organization's policies to verify if you need to modify any of these settings.

Based on your CleverTap account settings, we host your data in Europe (EU), the United States (US), Singapore (SG), or India (IN). To identify the region of your account and the corresponding region that you must select when configuring the bucket settings, refer to the following table:

📘

Set Up AWS Bucket Region

When setting up the AWS bucket region for your AWS account, ensure that the AWS bucket region matches your CleverTap account region. To identify the region of your CleverTap account, refer to the above table.

Also, you can set up the CleverTap account region only once during registration.

5. Click Create bucket. On successful bucket creation, the following message displays in the snack bar at the top:

The bucket you just created now shows up on your S3 console. We recommend you note down the name of your new bucket, as you will need it for the next step.

Configure S3 Bucket Details on CleverTap Dashboard

Using IAM Policy

The following are the two major steps to perform this task:
i. Copy IAM Policy from the CleverTap dashboard
ii. Add IAM Policy to S3 Bucket from AWS console.

Copy IAM Policy from the CleverTap Dashboard

To copy the IAM policy from the CleverTap dashboard:

1. Navigate to Settings > Partners and click View Details against Amazon S3. The Integrate analytics partner - Amazon S3 window displays on the right side of the screen.

2. Click + Amazon S3 Bucket to create a new bucket.
3. Enter the Bucket name.
4. Select IAM (Identity and Access Management) Policy option under Configure with section.

5. Click the icon to copy the policy to the clipboard and keep this window open for saving these details later.

Add IAM Policy to S3 Bucket on AWS Console

To add IAM policy to the S3 bucket:

1. Select the bucket from the Bucket page of the AWS console.
2. Select the Permissions tab.
3. Click Edit under the Bucket policy section and enter the policy that you copied in Step 4 of Copy IAM Policy from the CleverTap dashboard:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::062484260092:root"
            },
            "Action": "s3:PutObject*",
            "Resource": "arn:aws:s3:::bucket-name/*"
        },
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::062484260092:root"
            },
            "Action": "s3:PutObject*",
            "Resource": "arn:aws:s3:::bucket-name"
        }
    ]
}

🚧

IMPORTANT

Ensure that you replace all the occurrences of bucket-name in the above JSON payload with your actual bucket name.

4. Click Save Changes to save the policy.
5. Go back to the same window opened in Step 4 of Copy IAM Policy From CleverTap Dashboard and click Save Credentials.
   Amazon S3 bucket is now configured on both the AWS S3 console and CleverTap dashboard.

Using Access Key

The following are the two major steps to perform this task:
i. Create an API Key for Your S3 Bucket.
ii. Add Your S3 Bucket Details to CleverTap.

Create an API Key for Your S3 Bucket

This section demonstrates the creation of an AWS API key with write access to the bucket we created in the above step. CleverTap uses this API key to export data to your S3 bucket.

1. Click on your account name on the top right of the AWS console.
2. Select Security credentials.

3. Select Users from the left navigation and click Add user.

On clicking, the Add user page displays.

4. Enter the User name and select the Programmatic access checkbox.
5. Click Next:Permissions.

On clicking, Set permissions page displays.

6. Click Create group under Add user to group tab.

On clicking, Create group page displays.

7. Click Create policy. On clicking, Create policy page opens in a new tab.
8. Select the JSON tab and then paste the JSON code given below in the box.
9. Replace clevertap-example in the JSON code with the name of the S3 bucket you created in the above step.
   The permissions defined in this policy allow CleverTap to get information about your bucket and upload files to it.
