Add a Flex Instance to existing Twilio account or subaccount

We are excited to announce that Flex instances can now be added to any existing Twilio account or subaccount. Key features include:

  • Reuse existing resources: You can now add Flex to any existing (non-Flex) Twilio account. This allows you to leverage existing phone numbers and Studio flows without the need for time-consuming resource migrations.
  • Subaccount support: Flex instances can now be deployed within Twilio subaccounts. This is ideal for managing distinct Flex environments for:
    • Regional or departmental deployments: Separate instances for different countries or regions or departments like sales or support.
    • SDLC environments: Clear separation between Dev, Staging and Production.
    • Tenant isolation: ISVs can provide strict data and configuration isolation for end-customers within a multi-tenant architecture.
