问题
I have been trying to find a solution to accessing a datastore in one project from a different google app engine project. I went through the tutorial on accessing a datastore from a different project's compute engine, however, this is not what I am looking for. What is required here is accessing a datastore on one project from a different app engine project. Has anyone done this successfully? Any ideas?
Cheers

As @Patrice says, this is possible by using the Remote API for Java (or for Python), which lets you access different App Engine services from any other application, as stated in the documentation.
For a more specific information on how to access the Datastore remotely with the Remote API, please take a look at this article from the documentation that explains step by step all the procedure.
Please, take into account that if your Google account is configured to use 2-Step Verification, you will need an App Password that authorizes the app to access your account resources.

there is actually an API that lets you make calls to App Engine services from anywhere, even from another App, as long as the credentials are ok, it's called the "remote API"
