# Wowza Video REST API migration guide

Migrating your existing Wowza Video integrations to version 2.0 of the
REST API allows you to take advantage of new features and performance
improvements.

As you move the code base for your streaming workflow from one version
of the Wowza Video™ REST API to a later version, use this guide to track
what's changed and understand how these changes affect your code. While
this guide includes most changes you need to know, see the Wowza Video REST API reference documentation to confirm specific details of endpoint behavior in v2.0.

## Migration checklist

- Review deprecations to determine whether your code uses deprecated
endpoints or parameters.
- Review added and updated functionality to determine whether you want
to make use of new parameters or parameter values.
  - Update your code to use JSON Web Token-based authentication, rather than an API
key/access key, if you're upgrading from v1.8 or earlier. The
following table shows what authentication schemes our API
versions support. See [Authentication](/docs/wowza-video/about-the-rest-api/authentication) to learn how to get a JWT.
- For changes to operations and objects, as necessary.
- To reflect the new base URL for calls to the API. For example:
**Previous version:** `https://api.video.wowza.com/api/v1.11/live_streams`
**New version:** `https://api.video.wowza.com/api/v2.0/live_streams`
