Migrating from 1.x to 2.x

Version 2 of the Verify API has an improved developer experience and new features. Version 1 of the API will be fully deprecated in the future and any new development will be on Version 2.

Some of the exciting features of the V2 API include:

• Twilio helper libraries in JavaScript, Java, C#, Python, Ruby, and PHP
• Email channel
• PSD2 Secure Customer Authentication Support
• Improved Visibility and Insights

...and more!

This guide provides an introduction to the 2.x Verify API and a set of guidelines to migrate an application from 1.x to 2.x.

2.x Base API

Verify 2.x is now hosted on Twilio's API. The new base URL is:

https://verify.twilio.com/v2/

Credentials / Authentication

V1 required an Authy API Key. The Verify V2 API uses your Twilio Credentials found in the Console like in the following request:

curl -XPOST https://verify.twilio.com/v2/Services \
    -d FriendlyName=MyServiceName \
    -u '[YOUR ACCOUNT SID]:[YOUR AUTH TOKEN]'

Helper Libraries

Twilio helper libraries now support Verify. You no longer need the separate Authy helper libraries. We officially support libraries for:

• C#
• Java
• PHP
• Python
• Ruby
• Node.js

Check out our API Reference for examples and more information.

Applications are now Services

2.x relies on Services for configuration. In V1 you created an Authy or Verify Application and used that API Key to manage verifications. In V2 you need both your Twilio Credentials and a Service ID. You can create and update a Service in two ways:

1. With the Verify API
2. In the Verify Console

E.164 Phone Number Formatting for SMS and Voice

V1 used country code and phone number as two separate parameters. In V2, phone numbers are processed as one parameter in E.164 format like this: +15552317654.

PSD2 Support

Verify V2 supports PSD2 compliant transaction specific verifications with optional payee and amount fields. See the API reference documentation for details.

Improved Visibility and Insights

Only available with our new Verify API, view the status of your verifications in the console:
