Delivery

The Subscriptions API supports delivery to Amazon S3, Microsoft Azure Blob Storage, and Google Cloud Storage. Activation and processing for direct download is not currently supported.

For any cloud storage delivery option, you will need to create an cloud storage account with both write and delete access.

"delivery": [
