Export API for Authy User Phone Numbers



As of November 2022, Twilio no longer provides support for Authy SMS/Voice-only customers. Customers who were also using Authy TOTP or Push prior to March 1, 2023 are still supported. The Authy API is now closed to new customers and will be fully deprecated in the future.

For new development, we encourage you to use the Verify v2 API.

Existing customers will not be impacted at this time until Authy API has reached End of Life. For more information about migration, see Migrating from Authy to Verify for SMS(link takes you to an external page).



This API is only available for customers who intend to migrate Authy users from the Authy API to the Verify API.



By default, customers do not have access to this API endpoint. To request access, please contact support team.(link takes you to an external page)
