5.1.1

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

• App uploaded to RuStore Console.
• App passed moderation (you don't have to publish the app).

Important

• Test build signature (for example: debug) of the app must match the signature of the app build that was uploaded to the console and passed moderation (for example, release).

• The current version of RuStore is installed on the user's device.
• 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.
• Defold 1.6.2 and later.

caution

The service has some restrictions to work outside of Russia.

Connect to project

Connecting to project

1. Copy the plugin and the sample app projects from the official RuStore repository on GitFlic.
2. Open the Android project from the extension_libraries folder in your IDE.
3. Build the project via gradle assemble command. Upon successful build in the billing_example/extension_rustore_billing/lib/android and billing_example/extension_rustore_core/lib/android folders the following files will be created:
   • RuStoreDefoldBilling.jar;
   • RuStoreDefoldCore.jar.
4. 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 and RuStore SDK, 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)

• APPLICATION_ID — product ID form the RuStore Console.

Where are app IDs in the RuStore Console?

1. Navigate to the Applications tab and selected the needed app.
2. Copy the ID from the URL address of the app page — it is a set of numbers between apps/ and /versions. FOr example, for URL address https://console.rustore.ru/apps/123456/versions the app ID is 123456.

• DEEPLINK_SCHEME — 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.
• DEBUG_LOGS — 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 DEEPLINK_SCHEME must match the scheme specified in AndroidManifest.xml (see Deeplink processing).

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.

Attention!

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

The exceptions are SBP or mobile payment — see the explanation below.

When paying for CONSUMABLE products with SBP or mobile payment, one-stage payment is used, although the payment model is as in two-stage payments. It means that what a payment is in the PAID status, when paying with SBP or mobile payment, the money is withdrawn from the buyer's account, as well as the developer's fee is withdrawn from theirs. In this case, if a purchase is canceled from the PAID status the refund is made, not reverse. The developer's fee will not be returned. At the same time, to complete the purchase you still have to confirm purhchase — see the table below.

Payment method	Payment type	Payment in the PAID status
bank cards; Sber ID; SberPay; T-Pay; VK Pay.	Two-stage	Money is on hold on the buyer's account. Developer's fee is not applied. Payment cancellation (reverse) is available.
SBP; mobile payment.	One-stage	Money is withdrawn from the buyer's account. The developer's fee is applied. If a purchase is canceled form the PAID status the transaction is refunded, not reverse reversed. The developer's fee will not be returned.

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)

    local data = json.decode(value)
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.
