How to Manage AWS S3 Voice Recording Storage Settings Across Multiple Subaccounts – Twilio Support

Objective

Twilio Programmable Voice allows you to store call recordings in your own AWS S3 bucket. For organizations using multiple Twilio subaccounts, managing and updating the AWS S3 credentials for external recording storage can be a challenge especially when changes need to be applied across many subaccounts.

This article explains how AWS S3 recording storage is configured in Twilio, current limitations for bulk updates, and best practices for managing these settings at scale.

Key Points

Voice Recording External Storage settings are configured per account (including each subaccount).
There is currently no REST API endpoint or bulk update feature for managing these settings programmatically.
All changes to AWS S3 recording storage must be made manually in the Twilio Console for each account or subaccount.

Environment

Procedure

How External Storage Works

By default, Twilio stores call recordings in Twilio’s own storage.
If you enable "Voice Recording External Storage," Twilio will automatically store new recordings in your configured AWS S3 bucket.
This setting is managed separately for each account and subaccount.

Current Limitations

No API for Bulk Updates:
As of now, Twilio does not provide a REST API endpoint to programmatically configure or update AWS S3 recording storage settings. All changes must be made via the Twilio Console.
No Inheritance from Parent Account:
Settings configured on a parent account do not automatically propagate to subaccounts. Each subaccount must be updated individually.

Why Is This a Challenge?

Organizations with many subaccounts may need to update AWS credentials (for example, when rotating keys or changing buckets). Without an API or bulk update feature, this process is manual and time-consuming.

Workarounds and Best Practices

Manual Update:
Log in to each subaccount in the Twilio Console and update the AWS S3 settings under:
Console → Develop → Voice → Settings → General → Voice Recording External Storage
Automation Not Supported:
There is currently no supported method to automate this process via API or script.

Feature Request and Feedback
