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.is_supported()
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.
local bridge = require("bridge.bridge")
function init(self)
local id = "test_product" -- id you specified in the config file
bridge.payments.purchase(id, function (_, purchase)
-- success
end, function (_, error)
-- error
end)
end
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.
local bridge = require("bridge.bridge")
function init(self)
local id = "test_product" -- id you specified in the config file
bridge.payments.consume_purchase(id, function (_, purchase)
-- success
end, function ()
-- error
end)
end
Catalog of All Items
Retrieve a list of all available in-game items that players can purchase to display in the game store.
local bridge = require("bridge.bridge")
function init(self)
bridge.payments.get_catalog(function (_, catalog)
-- success
for key, value in pairs(catalog) do
local id = value.id
local price = value.price
local priceCurrencyCode = value.priceCurrenyCode
local priceValue = value.priceValue
end
end, function ()
-- error
end)
end
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).
local bridge = require("bridge.bridge")
function init(self)
bridge.payments.get_purchases(function (_, purchases)
-- success
for key, value in pairs(purchases) do
local id = value.id
end
end, function ()
-- error
end)
end
