Sandbox AP Data Exchange API Setup Details

Hello!

I am definitely new here, and I have the mission of studying the Legal Tracker API to retrieve some information. However, I have a question: does a Sandbox environment actually exist to obtain fictitious data and verify if the API is working?

I tried accessing the link "Sandbox AP Data Exchange API Setup Details", thinking it would redirect me to a page related to the topic, but it only takes me back to a main address.

Could someone guide me on whether this environment actually exists or not?

Thank you for your help.
