Overview

This document is an appendix to the Unity SDK Integration Guide, specifically for publishers using the direct communication model with the Secret Publisher Token. For further assistance please refer to the DirectCheckoutSample file.

Prerequisites

Before starting, you need to gather some information from the Appcharge dashboard:

Secret Publisher Token: Navigate to Admin -> Integration -> Publisher Token to get your secret token. This enables direct communication with Appcharge servers.

Setup the AppChargeConfig File

Locate the AppChargeConfig file in the folder Assets/Resources/AppCharge.
Configure the Secret Publisher Token setting:

Setting	Description
Secret Publisher Token	Paste your secret token if you plan to use direct access to the checkout.

Initialize the Checkout

Create a checkout model by using the following code snippet:

AppChargeCheckoutModel checkoutModel = new AppChargeCheckoutModel(...);

Parameters required for the checkout model:

Parameter	Type	Description
`customerId`	`string`	The name of the customer
`customerEmail`	`string`	Customer email address
`price`	`float`	Offer price (in cents)
`currency`	`string`	Offer price currency. For example: "usd", "eur"
`offerName`	`string`	The name of the offer
`offerSku`	`string`	Offer's sku
`offerAssetUrl`	`string`	An image URL for the offer
`offerDescription`	`string`	Offer's description

If your offer contains a set of items (bundle), add these as followed:

// Utilize the model by adding extra items
checkoutModel.AddItem(...);

Here are the parameters needed for creating an item:

Parameter	Description
`itemName`	The name of the item
`assetUrl`	An image which represents the item
`itemSku`	Item's sku
`itemAmount`	Item's Quantity

Example:

// Prepare checkout model
string customerId = "JohnDoe";
string customerEmail = "[email protected]";
int price = 129; // in USD cents 
string currency = "usd";
string offerName = "BestDealPackage"; 
string offerSku = "best_deal_package";
string offerAssetUrl = "https://media-dev.appcharge.com/media/64ad4f25cc1a482bac467ae5/fire-fire-logo-fire-fire-icon-fire-sign-fire-symbol-transparent-background-ai-generative-free-png.png";
string offerDescription = "Coin Pack Bundle";

// Declare a model for getting session token
checkoutModel = new RequestModel(
customerId,
customerEmail,
price,
currency,
offerName,
offerSku,
offerAssetUrl,
offerDescription
);

// Utilize the model by adding extra items
string itemName = "Coins";
string itemAssetUrl = "https://media-dev.appcharge.com/media/product-3.png";
string itemSku = "coins";
int itemAmount = 300;
checkoutModel.AddItem(itemName, itemAssetUrl, itemSku, itemAmount);

Launch the Checkout

Open the checkout using the checkoutModel (step 5 in the full SDK Guide):

AppchargeManager.OpenCheckoutDirect(checkoutModel);

This function should be called when a user presses a button in your in-game store and once you initialized the checkoutModel.
