## The normal **FastAPI** app

Let's first see how the normal API app would look like before adding the callback.

It will have a *path operation* that will receive an `Invoice` body, and a query parameter `callback_url` that will contain the URL for the callback.

This part is pretty normal, most of the code is probably already familiar to you:

            projectsConfigured(":buildSrc", ":b")
            buildModelCreated()
            modelsCreated(":", ":a")
        }

        outputContains("Callback before root project 'root'")
        outputContains("Callback before project ':a'")
        outputContains("Callback before project ':b'")


        when:
        withIsolatedProjects()
        def model2 = runBuildAction(new FetchCustomModelForEachProject())

	mustHaveSwig(t)
	mustHaveCxx(t)
	run(t, "testdata/callback", false, "Call")
	t.Run("lto", func(t *testing.T) { run(t, "testdata/callback", true, "Call") })
}

func TestCallback(t *testing.T) {
	testenv.MustHaveCGO(t)
	mustHaveSwig(t)
	mustHaveCxx(t)
	run(t, "testdata/callback", false, "Callback")
	t.Run("lto", func(t *testing.T) { run(t, "testdata/callback", true, "Callback") })
}

    Tensor::DeleterCallback callback = [&done](void* data, size_t len) {
      done = true;
    };

    Tensor tensor =
        Tensor::FromBuffer(/*dtype=*/TF_INT32, /*shape=*/shape,
                           /*data=*/data_vector.data(),
                           /*len=*/data_vector.size() * sizeof(int32_t),
                           /*deleter=*/callback, &status);
