6.0.0

With RuStore you can integrate payments in your mobile app.

tip

If you are in doubt read the instruction in the usage scenarios.

Implementation example

Look at the example app to learn how to integrate the SDK.

Prerequisites

The user and the app are not banned in RuStore.
In-app purchases for the app are enabled in RuStore Console.
Defold 1.6.2 and later.

caution

The service has some restrictions to work outside of Russia.

Connecting to project

Connecting to project

Copy the plugin and the sample app projects from the official RuStore repository on GitFlic.
Copy the billing_example/extension_rustore_billing and billing_example/extension_rustore_core folders in the root of your project.

Deeplink handling

RuStore SDK uses deeplink to handle third-party payment applications. This makes it easier to pay with third-party apps and return to your app.

To configure deeplinks functionality in your app, define deeplinkScheme in your AndroidManifest file and redefine the onNewIntent method of your activity.

AndroidManifest.xml
<activity>
<!-- RUSTORE BILLING INTENT FILTER -->
<activity android:name="ru.rustore.defold.billing.RuStoreIntentFilterActivity" android:exported="true" android:launchMode="singleTask">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <!-- Set your appscheme -->
        <data android:scheme="yourappscheme" />
    </intent-filter>
</activity>

Replace yourappscheme in the example above with the name of your scheme. For example, ru.package.name.rustore.scheme.

info

The scheme defined in the AndroidManifest file must match the scheme you specify in the create method of the RuStore SDK billing.

App example contains a modified manifest in the billing_example/extension_rustore_billing/manifests/android/AndroidManifest.xml file

Initialization

Initialize the library before calling its methods.

For initialization, call the init() method.

Calling init
local APPLICATION_ID = "123456"
local DEEPLINK_SCHEME = "yourappscheme"
local DEBUG_LOGS = true

rustorebilling.init(APPLICATION_ID, DEEPLINK_SCHEME, DEBUG_LOGS)

123456 — application code from the RuStore console (example: https://console.rustore.ru/apps/123456).
To get the app ID, copy digits from the URL address of the app page in the RuStore Console that appear after apps/.
yourappscheme — deeplink scheme that i sused to return to your app after paying with a third party payment app (for example, SberPay or SBP). SDK generates its own host to this scheme.
debugLogs — flag that enables/disables logging. Set it to true, if you want events to be logged. Otherwise, set it to false.

note

Tye deeplink scheme that is passed in yourappscheme must match the scheme specified in AndroidManifest.xml (see Deeplink processing).

Before you start

Payments availability check

The current version of RuStore is installed on the user's device.
RuStore app supports payments.
User is authorized in RuStore.
The user and the app are not banned in RuStore.
In-app purchases for the app are enabled in RuStore Console.

You must subscribe to events once before using this method:

rustore_check_purchases_available_success;
rustore_check_purchases_available_failure.

Subscription to events
function init(self)
    # rustorebilling initialization
 
    rustorecore.connect("rustore_check_purchases_available_success", _check_purchases_available_success)
    rustorecore.connect("rustore_check_purchases_available_failure", _check_purchases_available_failure)
end
  
function _check_purchases_availability_success(self, channel, value)
    local data = json.decode(value)
end
  
function _check_purchases_availability_failure(self, channel, value)
    local data = json.decode(value)
end

Calling check_purchases_availability
rustorebilling.check_purchases_availability()

The rustore_check_purchases_availability_success callback returns a JSON string with the service availability information (see below).

isAvailable — compliance with the payments availability conditions (true/false).
cause — error information.

The error structure is described in Error Handling.

The rustore_check_purchases_availability_failure callback returns a JSON string with the error information. The error structure is described in Error Handling.

State model (purchaseState)

CONSUMABLES - purchase state model

NON-CONSUMABLES - purchase state model

(SUBSCRIPTIONS) - purchase state model

Consume (confirm) purchase

Products that require confirmation

Please, keep in mind the purchase type. Confirmation is only needed if your product is CONSUMABLE and can be purchased more than once.

To correctly deliver such products, confirm purchases with the confirmPurchase method. On delivering a product, use server validation. Deliver your product only after the payment (invoice) is in the CONFIRMED status. Use the addOnSuccessListener callback of the confirmPurchase method to deliver products.

caution

The PAID status is intermediate and meas the user's money is put on hold on their card, so you need to confirm the purchase.

ConfirmPurchase request

Us the confirm_purchase() method to confirm a purchase. Purchase confirmation request must be accompanied by the delivery of the product. After calling the confirmation method the purchase changes its state to CONSUMED.

You must subscribe to events once before using this method:

rustore_on_confirm_purchase_success;
rustore_on_confirm_purchase_failure.

Subscription to events
function init(self)
    # rustorebilling initialization
     
    rustorecore.connect("rustore_on_confirm_purchase_success", _on_confirm_purchase_success)
    rustorecore.connect("rustore_on_confirm_purchase_failure", _on_confirm_purchase_failure)

end
  
function _on_confirm_purchase_failure(self, channel, value)
    local data = json.decode(value)
end

Calling confirm_purchase
# Your purchase confirmation UI implementation
function _on_confirm_purchase_pressed(purchaseId):
    rustorebilling.confirm_purchase(purchaseId)
end

purchaseId — product ID.

Server validation

If you need to validate a successful app using API RuStore methods, you can use the subscriptionToken value, from the json string received upon a successful product purchase.

SubscriptionToken consists of invoiceId and userId of the purchase separated by period: $invoiceId.$userId.

Getting subscriptionToken from the purchase result

function _on_purchase_product_success(self, channel, value)
    local data = json.decode(value)
 
    if data.type == "Success" then
        local subscriptionToken = data.data.subscriptionToken
        yourApi.validate(subscriptionToken)
    end
end

You can also get subscriptionToken from the purchases list.

function _on_get_purchases_success(self, channel, value)
    local data = json.decode(value)

	for key, value in pairs(data) do
        yourApi.validate(value.subscriptionToken)
    end
end

Purchase cancellation

To cancel a purchase, use the delete_purchase method.

You must subscribe to events once before using this method:

rustore_on_delete_purchase_success;
rustore_on_delete_purchase_failure.

Calling cancellation method

Subscription to events
function init(self)
    # rustorebilling initialization
     
    rustorecore.connect("rustore_on_delete_purchase_success", _on_delete_purchase_success)
    rustorecore.connect("rustore_on_delete_purchase_failure", _on_delete_purchase_failure)
end
 
function _on_delete_purchase_success(self, channel, value)
    local data = json.decode(value)
end
  
function _on_delete_purchase_failure(self, channel, value)
    local data = json.decode(value)
end

Calling delete_purchase
# Your purchase cancellation UI implementation
function _on_delete_purchase_pressed(purchaseId):
    rustorebilling.delete_purchase(purchaseId)
end

purchaseId — product ID.

The rustore_on_delete_purchase_success callback returns purchase ID:

purchaseId — product ID.

The rustore_on_delete_purchase_failure callback returns a JSON string with the error information. Available fields:

purchaseId — product ID.
cause — error information.

The error structure is described in Error Handling.

info

Use this method if your app logic is related to purchase cancellation. The purchase is canceled automatically after a 20-min timeout, or upon a second purchase from the same customer.

Handling pending payments

Handling of unfinished payments is done by the developer.

To confirm a purchase of CONSUMABLE product in the PAID state, call the [purchase confirmation method].(#confirm) (see Retrieve purchase details).

When dealing with purchase cancellation using payment processing methods take into account your business logic. Some developers implement additional checks before purchase confirmation or cancellation. In that case, make a separate purchase state request.

tip

For example, if the user paid for the product that you cannot deliver for some reason, call the payment cancellation method for the purchase in the PAID status to cancel the purchase.

If the get purchases list method returns a purchase in the INVOICE_CREATED state, you can us the purchase cancellation method. For instance, if you don't want to see a purchase in that state in the purchase list. This is optional as RuStore handles cancellation of such purchases on its side.

info

In some cases, after paying with a bank app (SBP, SberPay, T-Pay, etc.) and returning to your app the purchase status may still be INVOICE_CREATED while payment status shows that the purchase failed. This is caused by the purchase processing time by the bank. In this case, you need to adapt your screen lifecycle to the product list retrieval logic.

Alternatively, you can implement cancellation of purchases in the INVOICE_CREATED state only through user action in your app. For example, create a dedicated button for this purpose.

Event logging

If you need to log payment library events, add optional debugLogs in the init call and subscribe to the events:

rustore_on_payment_logger_debug;
rustore_on_payment_logger_error;
rustore_on_payment_logger_info;
rustore_on_payment_logger_verbose;
rustore_on_payment_logger_warning.

local APPLICATION_ID = "123456"
local DEEPLINK_SCHEME = "yourappscheme"
local DEBUG_LOGS = true
local LOG_TAG = "yourtag"

function init(self)
	rustorecore.connect("rustore_on_payment_logger_debug", _on_payment_logger_debug)
	rustorecore.connect("rustore_on_payment_logger_error", _on_payment_logger_error)
	rustorecore.connect("rustore_on_payment_logger_info", _on_payment_logger_info)
	rustorecore.connect("rustore_on_payment_logger_verbose", _on_payment_logger_verbose)
	rustorecore.connect("rustore_on_payment_logger_warning", _on_payment_logger_warning)
	
	rustorebilling.init(APPLICATION_ID, DEEPLINK_SCHEME, DEBUG_LOGS)
end

function _on_payment_logger_debug(self, channel, value)
	rustorecore.log_debug(LOG_TAG, value)
end

function _on_payment_logger_error(self, channel, value)
	rustorecore.log_error(LOG_TAG, value)
end

function _on_payment_logger_info(self, channel, value)
	rustorecore.log_info(LOG_TAG, value)
end		

function _on_payment_logger_verbose(self, channel, value)
	rustorecore.log_verbose(LOG_TAG, value)
end

function _on_payment_logger_warning(self, channel, value)
	rustorecore.log_warning(LOG_TAG, value)
end

Logging enabling parameter:

DEBUG_LOGS — enable logging (logging will be automatically disabled for Release builds).

All logging callbacks return a JSON string. Available fields:

e — error information or "null". The error structure is described in Error Handling.
message – error description.

Changing interface theme

To dynamically change the theme, use the set_theme method.

setTheme usabe example

rustorebilling.set_theme(0)

0 - dark theme;
1 - light theme.

Error handling

Error structure

Processing json error
function _on_failure(self, channel, value)
    local data = json.decode(value)
	
	local name = data.simpleName
	local message = data.detailMessage
end

simpleName – error name.
detailMessage – error description.

Possible errors
