In-Game Purchases

Enable players to purchase items, upgrades, or currency within your game to enhance their experience and generate revenue.

There are two types of purchases — permanent (e.g., ad removal) and consumable (e.g., in-game coins).

Support

Check if in-game purchases are supported to offer items or upgrades within the game.

bridge.payments.isSupported

Setup

Setup in-game purchases in the config file. For each product add an id and fill in the information for the required platforms, example for one product:

{
    ...    
    "payments": [
        {
            "id": "test_product",
            "playgama": {
                "amount": 1 // int price in Gam
            },
            "playdeck": {
                "amount": 1, // int price in Telegram Stars
                "description": "TEST PRODUCT"
            }
        }
    ]
}

Purchase

Allow players to buy items or upgrades in your game to enhance their gameplay experience.

bridge.payments.purchase("test_product") // id you specified in the config file
    .then((purchase) => {
        // success
        console.log('Purchase completed, id:', purchase.id)
    })
    .catch(error => {
        // error
    })

Each platform provides its own set of properties for a purchase, so make sure to check the official documentation of the specific platform you are targeting.

Use purchase data to verify the purchase. Currently, the Playgama API verification only supports playgama and msn platforms.

curl -X POST "https://playgama.com/api/v1/bridge/verify" \
  -H "Content-Type: application/json" \
  -d '{"platform":"<PLATFORM_ID>","type":"purchase","data":{ <...purchase> }}'

# {
#   "success": true
# }
#   or
# {
#   "success": false,
#   "errorMessage": "<errorMessage>"
# }

Consume Purchase

Consume purchased items, such as in-game currency, once they are used, to manage inventory and player progression.

bridge.payments.consumePurchase("test_product") // id you specified in the config file
    .then((purchase) => {
        // success
        console.log('Consume completed, id:', purchase.id)
    })
    .catch(error => {
        // error
    })

Catalog of All Items

Retrieve a list of all available in-game items that players can purchase to display in the game store.

bridge.payments.getCatalog()
    .then(catalogItems => {
        // success
        catalogItems.forEach(catalogItem => {
            console.log('ID: ' + catalogItem.id)
            console.log('Price: ' + catalogItem.price)
            console.log('Price Currency Code: ' + catalogItem.priceCurrencyCode)
            console.log('Price Value: ' + catalogItem.priceValue)
        })
    })
    .catch(error => {
        // error
    })

List of Purchased Items

Retrieve a list of items that the player has purchased to manage their inventory and provide access to purchased content.

If the user loses internet connection when making an in-game purchase, the purchase might remain unprocessed. To avoid this, check for unprocessed purchases using this method (e.g., each time the game is launched).

bridge.payments.getPurchases()
    .then(purchases => {
        // success
        purchases.forEach(purchase => {
            console.log('ID: ' + purchase.id)
        })
    })
    .catch(error => {
        // error
    })
