To check for purchase support on a platform in the SDK, use the gp.payments.isAvailable property.

JavaScript

// Checking for purchase support on a platform
if (gp.payments.isAvailable) {
    // You can make purchases
}

Unity

// Check payments on paltform
if (GP_Payments.IsPaymentsAvailable()) {
    // can show / purchase products
}

Payment Rules

Stick to payments rules.

There are two types of payments: one-time and permanent.

Example of a one-time purchase:

• Buy 1000 gold
• Buy chest
• Restore Lives

tip

One-time purchases must be consumed immediately.

An example of a permanent purchase:

• Disable ads
• VIP status
• Increase x5 reward per level

Constant purchases do not need to be consumed. As soon as the purchase is paid, it will always be visible to the user, until it is used up.

One-time purchase rules

JavaScript

// 1. Make purchase
await gp.payments.purchase({ tag: 'GOLD_1000' });

// 2. Give a reward
gp.player.add('gold', 1000);

// 3. Save player progess on server
await gp.player.sync();

// 4. Consume purchase
await gp.payments.consume({ tag: 'GOLD_1000' });

Unity

// 1. Make purchase
GP_Payments.Purchase("EXTRA_GOLD");

// 2. Give a reward
GP_Player.Add('gold', 1000);

// 3. Save player progess on server
GP_Player.Sync();

// 4. Consume purchase
GP_Payments.Consume("EXTRA_GOLD");

Permanent purchase rules

JavaScript

// 1. Make purchase
await gp.payments.purchase({ tag: 'VIP' });

// 2. Checking for purchase availability when needed
if (gp.payments.has('VIP')) {
    // do something with VIP status
}

Unity

// 1. Make purchase
GP_Payments.Purchase('VIP', OnPurchaseSuccess, OnPurchaseError);

private void OnPurchaseSuccess(string productIdOrTag){
    if(productIdOrTag == 'VIP')
        GP_Player.Set('VIP', true);
}
private void OnPurchaseError() => Debug.Log("PURCHASE: ERROR");

// 2. Checking for purchase availability when needed
if (GP_Player.GetBool('VIP')) {
    /// do something with VIP status
}
