Hise with Gumroad licensing system

[Avián]

Hi all, I scripted this License-Test in my Plugin and it works fine:

// -------------------------
// GUMROAD / TEST LICENSING
// -------------------------

const var LicenseField   = Content.getComponent("Label7");
const var ActivateButton = Content.getComponent("Button2");
const var Keyboard       = Content.getComponent("FloatingTile1");
const var LockOverlay    = Content.getComponent("Panel2");   // Overlay-Panel

var pluginUnlocked = false;


// -------- Plugin beim Start SPERREN --------
pluginUnlocked = false;

// Overlay aktiv → blockt alle Klicks
LockOverlay.set("visible", true);
LockOverlay.set("enabled", true);

// Keyboard zusätzlich sperren
Keyboard.set("enabled", false);

// Aktivierungs-UI aktiv lassen
LicenseField.set("enabled", true);
ActivateButton.set("enabled", true);


// ---------------- Button: Aktivieren ----------------
inline function onActivateButton(c, v)
{
    if (!v) return;

    local key = LicenseField.get("text");
    if (key == "") return;

    local TEST_KEY = "TEST-1234";

    if (key == TEST_KEY)
    {
        Console.print("Local test activation OK");

        pluginUnlocked = true;

        // Overlay weg → Plugin wieder benutzbar
        LockOverlay.set("visible", false);
        LockOverlay.set("enabled", false);

        // Keyboard wieder freigeben
        Keyboard.set("enabled", true);

        // --- ALLE Controls wieder aktiv ---
        Category.set("enabled", true);
        Variant.set("enabled", true);

        Attack.set("enabled", true);
        Hold.set("enabled", true);
        Decay.set("enabled", true);
        Sustain.set("enabled", true);
        Release.set("enabled", true);

        SaveButton.set("enabled", true);

        // Lizenz-UI verstecken
        ActivateButton.set("visible", false);
        LicenseField.set("visible", false);

        return;
    }

    Console.print("Wrong key");
}

ActivateButton.setControlCallback(onActivateButton);

Now I want to implement the auto-licensesystem from gumroad. Can someone help me to set up the right script for this? Gumroad License:

https://gumroad.com/help/article/76-license-keys

I would be very grateful if someone could help me with this. I want the buyer to have to activate the software only once. After that, no further activation should be required. The license should allow the user to cover 1-3 devices, and it must work on both Windows and Mac. Thank you in advance. Best regards.

@Avián You should use Server.callWithPOST
https://docs.hise.audio/scripting/scripting-api/server/index.html#callwithpost

something like this based on what I read from the docs of gumroad (i'm not using gumroad, so I don't know if it works)

Server.setBaseURL("https://api.gumroad.com");

const var params =
{
    "product_id": "1234",
    "license_key": "your_license_key",
    "increment_uses_count": "true"
};

Server.callWithPOST("v2/licenses/verify", params, function(status, response)
{
    if(status == Server.StatusOK)
    {
        if(response.success)
        {
            Console.print("License valid");
            Console.print("Uses: " + response.uses);
            Console.print("Product: " + response.purchase.product_name);
        }
        else
        {
            Console.print("License invalid");
        }
    }
    else
    {
        Console.print("HTTP error: " + status);
    }
});
