# New Features: Verify API Voice, Flash Call, and API Updates

### 25, May 2021

We're excited to announce that our Verify API now offers Voice and Flash Call as channels for sending 2FA codes. The new features supported are:

* Delivering a verification code through voice call
* Delivering a verification code through flash call
* Delivering a verification code specific to the PSD2 use case
* Specifying the language for a verification code delivered through voice call or SMS

With these new features, we introduced some changes to the verification API while doing our best to maintain backward compatibility. Users who have already integrated with the API should read the release notes carefully and make the appropriate planning to accommodate the changes.
