Hi,
The Adobe Developer Console is a centralized platform that provides access to Adobe APIs, Events, and Runtime services, along with tools for building applications and plugins. It allows developers to create and manage Projects, which act as containers for multiple APIs and event subscriptions. With the Developer Console, you can build cross-cloud applications, integrations, and plugins, while also accessing advanced features like service-to-service integrations and event journaling. It serves as the ultimate destination for developers looking to leverage Adobe's ecosystem for their projects.
When creating these integrations/apps, you need an authentication and authorization method to allow other systems to access or interact with your Adobe services. This is where JWT or OAuth comes into play. These are the available methods you can select in the Adobe Developer Console for such access. It's important to note that the deprecation refers specifically to the authentication method you may be using for different integrations or applications, not to the Developer Console itself.
Hope this makes sense!
