Deprecation of legacy Twilio API domain patterns
Starting April 28, 2026, we’re deprecating these region-specific API domain patterns:
api.ie1.twilio.com
api.au1.twilio.com
api.br1.twilio.com
api.de1.twilio.com
api.jp1.twilio.com
api.sg1.twilio.com
api.us2.twilio.com
To keep everything running smoothly, update your applications to use api.twilio.com instead. Here's what to check and update:
API base URLs: Your migration path depends on your data processing requirements. See the Twilio API Domain Migration Guide for detailed instructions based on whether you need US or regional processing.
SDK initializations: For these changes, refer to the Twilio API Domain Migration Guide.
Network configurations: Make sure that DNS allowlists, proxies, and firewall rules are updated to accept the new api.twilio.com domain.
