Twilio deprecates legacy region-specific API domain patterns
Twilio deprecated seven regional API domain patterns and directs applications, SDK initialisation and network allowlists to api.twilio.com.
Previous state
Applications could use api.ie1.twilio.com, api.au1.twilio.com, api.br1.twilio.com, api.de1.twilio.com, api.jp1.twilio.com, api.sg1.twilio.com or api.us2.twilio.com as regional API domains.
Current state
Those regional patterns are deprecated and Twilio directs callers to api.twilio.com, with the migration path determined by data-processing requirements.
Affected users
Who needs to care
Twilio integrations with regional API base URLs, regional SDK initialisation or DNS, proxy and firewall rules tied to the deprecated hosts.
Required response
What to do
Follow the Twilio API Domain Migration Guide, update API and SDK configuration and permit api.twilio.com in network controls.
Evidence boundary
What the source does not prove
Twilio states that deprecation starts on 28 April 2026 but does not publish a universal final shutdown date in this notice. Regional processing requirements still affect the migration path.
