Verify v1 API has reached End of Sale. It 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. v2 has an improved developer experience and new features, including:
- Twilio helper libraries in multiple languages
- PSD2 Secure Customer Authentication Support
- Improved Visibility and Insights
Existing customers will not be impacted at this time until Verify v1 API has reached End of Life. For more information about migration, see Migrating from 1.x to 2.x.
