Export Message MDMs


Sublime Enterprise users on Cloud and AWS CloudFormation deployments can configure all Message Data Models (MDMs) to export to an S3 bucket that you own every 10 minutes.

Note: Enterprise users on Docker deployments can request assistance with exports to S3 in your Sublime support Slack channel.

1. Setup

Before starting, you'll need to:

  1. Determine the ID of the AWS account uploads will be coming from (used for AWS_ACCOUNT_ID placeholder below):
    • If you've deployed into a self-managed AWS environment, then the Account ID will be that of the AWS account.
    • If you are a Sublime Cloud user located in the EU, then the value you'll use is 128225141972.
    • For all other Sublime Cloud users, then the value you'll use is 415365657389.
  2. Create an S3 bucket in the AWS account where you want the events exported to. We recommend creating a new S3 bucket specifically for these exports instead of re-using an existing one.

2. Configure bucket permissions

These instructions assume you have a bucket with default settings and bucket policies.

  1. Navigate to your desired bucket in the AWS S3 dashboard, and go to the Permissions tab.
  2. Click Edit on the Block public access (bucket settings) section, which should bring you to the following page:
  1. Make sure the final checkbox is deselected. The other three should remain checked, unless you have a particular reason not to. Save these changes.
  2. Now, scroll down to the Bucket policy section (still on the Permissions tab). This is where we'll set up the policy to allow cross-account uploads from the account Sublime is running in. Click Edit on the Bucket Policy tab.
  3. Use the following template as the Policy. Update the placeholders AWS_ACCOUNT_ID (use the ID from Setup step 1 -- the AWS account where exports are coming from) and BUCKET_NAME_HERE with the corresponding values. Save changes once complete.
    	"Version": "2012-10-17",
    	"Statement": [
    			"Sid": "AllowSublimeWrites",
    			"Effect": "Allow",
    			"Principal": {
    				"AWS": "arn:aws:iam::AWS_ACCOUNT_ID:root"
    			"Action": [
    			"Resource": [
  4. The bucket is now configured for cross-account uploads from the Sublime platform.

3. Configure settings in Sublime

To complete configuration, head over to Account > Admin in your Sublime dashboard and scroll down to the Message Export setting. Configure the following fields:

  • S3 bucket name: Bucket names must be globally unique. They can be named anything but here’s a sample format: sublime-message-events-export-<your-organization-name>
  • S3 prefix (optional): Configuring a prefix will store your exports in a folder with the prefix name within the bucket. A prefix is not necessary if the bucket is not used for any other use cases (recommended).
    Example prefix: exports
  • S3 region: the region you created the S3 bucket in

After hitting Apply, it may take up to 20 minutes before you start seeing events in S3. After the first export, exports take place every 10 minutes.

The filename (with prefixes) is output as follows:


Where each is as follows:

ConfiguredKeyPrefix: The key prefix that was configured in your Sublime Platform settings.

MessageGroupID: The ID of the message group that the message is in

MessageID: The ID of the specific message stored in the file


The file is a JSON file that contains a top-level, single JSON object representing the MDM that was processed. The full MDM schema can be found here.
