To use the SDK the following requirements must be met:
- Android Studio 3.3 or newer
- Android SDK Tools 26.1.1 or newer
- Android Platform Version: API 28: Android 9.0 (Pie) revision 6 or later
- Clone goSellSDK library from Tap repository
[email protected]:Tap-Payments/goSellSDK-Android.git - Add goSellSDK library to your project settings.gradle file as following
include ':library', ':YourAppName'
- Setup your project to include goSellSDK as a dependency Module.
- File -> Project Structure -> Modules -> << your project name >>
- Dependencies -> click on + icon in the screen bottom -> add Module Dependency
- select goSellSDK library
JitPack is a novel package repository for JVM and Android projects. It builds Git projects on demand and provides you with ready-to-use artifacts (jar, aar).
To integrate goSellSDK into your project add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}Step 2. Add the dependency
dependencies {
implementation 'com.github.Tap-Payments:goSellSDK-Android:2.3.0'
}Proguard rules for SDK Library are:
-keepattributes Signature
-keepclassmembernames,allowobfuscation interface * {
@retrofit2.http.* <methods>;
}

First of all, goSellSDK should be set up. To set it up, add the following lines of code somewhere in your project and make sure they will be called before any usage of goSellSDK.
Below is the list of properties in goSellSDK class you can manipulate. Make sure you do the setup before any usage of the SDK.
To set it up, add the following line of code somewhere in your project and make sure it will be called before any usage of goSellSDK, otherwise an exception will be thrown. Required.
Android
GoSellSDK.init(context, "sk_XXXXXXXXXXXXXXXXXXXXXXXX","app_id");authToken- to authorize your requests.// Secret key (format: "sk_XXXXXXXXXXXXXXXXXXXXXXXX")app_id- replace it using your application ID "Application main package".
Don't forget to import the class at the beginning of the file:
Android:
import company.tap.gosellapi.GoSellSDK;SDK mode defines which mode SDK is operating in, either sandbox or production.
SDK Mode is automatically identified in the backend based on the secrete key you defined earlier in setup process.
Localization language of the UI part of the SDK. This is locale identifier.
Make sure it consists only from 2 lowercased letters and is presented in the list of availableLanguages property of goSellSDK class.
Notice: SDK user interface layout direction is behave similar to your App. There is no effect come form the SDK back to your application locale.
goSellSDK should be set up. To set it up, add the following lines of code somewhere in your project and make sure they will be called before any usage of goSellSDK.

You have to choose only one Mode of the following modes:

}PaymentDataSource is an interface which you should implement somewhere in your code to pass payment information in order to be able to access payment flow within the SDK.
The following table describes its structure and specifies which fields are required for each of the modes.
| Member | Type | Required | Description | ||
|---|---|---|---|---|---|
| Android | Purchase | Authorize | Card Saving | ||
| mode | TransactionMode | false | Mode of the transactions (purchase or authorize). If this property is not implemented, purchase mode is used. | ||
| customer | Customer | true | Customer information. For more details on how to create the customer, please refer to Customer class reference. | ||
| currency | Currency | true | false | Currency of the transaction. | |
| amount | BigDecimal | false | Payment/Authorization amount. Note: In order to have payment amount either amount or items should be implemented. If both are implemented, items is preferred. |
||
| items | ArrayList [PaymentItem] | false | List of items to pay for. Note: In order to have payment amount either amount or items should be implemented. If both are implemented, items is preferred. |
||
| taxes | ArrayList [Tax] | false | You can specify taxation details here. By default, there are no taxes. Note: Specifying taxes will affect total payment/authorization amount. |
||
| shipping | ArrayList [Shipping] | false | You can specify shipping details here. By default, there are no shipping details. Note: Specifying shipping will affect total payment/authorization amount. |
||
| postURL | String | false | The URL which will be called by Tap system notifying that payment has either succeed or failed | ||
| paymentDescription | String | false | Description of the payment. | ||
| paymentMetadata | String | false | Additional information you would like to pass along with the transaction. | ||
| paymentReference | Reference | false | You can keep a reference to the transaction using this property | ||
| paymentStatementDescriptor | String | false | Statement descriptor. | ||
| require3DSecure | Boolean | false | Defines if 3D secure check is required. If not implemented, treated as true. Note: If you disable 3D secure check, it still may occure. Final decision is taken by Tap |
||

SessionDelegate is an interface which you may want to implement to receive payment/authorization/card saving status updates and update your user interface accordingly when payment window closes.

Notifies the receiver that authorization has failed.
Android
- void authorizationFailed(Authorize authorize);authorize: Authorize object that has failed (if reached the stage of authorization).

*Android:
- void cardSavingFailed(@NonNull Charge charge);Charge: Charge object with the details (if reached the stage of card saving).
Notifies the receiver that the card has successfully tokenized.
Android
- void cardTokenizedSuccessfully(@NonNull Token token);token: card token object.
Notifies the receiver with list of saved cards for a customer. If customer has no cards then you will receive the same response but with empty cards array.
Android
- void savedCardsList(@NonNull CardsList cardsList);cardsList: CardsList model that holds the response.

Android:
- void sessionIsStarting();Notifies the receiver that session has successfully started and shown the SDK UI on the screen. You might want to use this method if you are not using PayButton in your application and want to hide a loader after SDK UI has appeared on the screen.

- void sessionHasStarted();Notifies the receiver that session has failed to start.
Android:
- void sessionFailedToStart();Notifies the receiver (Merchant Activity) that the user cancelled payment process, clicked on soft back button, clicked hard back button or clicked Header cancel button.
