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.
