Drop-in integration guide

Create a payment form using Drop-in.

Getting started
You can set up Drop-in in seven easy steps:‌
​Step 1: Include DigitalRiver.js on your page​
​Step 2: Include the base Drop-in CSS file​
​Step 3: Initialize DigitalRiver.js with your public key​
​Step 4: Create a container for Drop-in​
​Step 5: Create a Configuration object for Drop-in​
​Step 6: Use the Configuration object to create an instance of Drop-in​
​Step 7: Place Drop-in on your Checkouts or Customers page​
Step 1: Include DigitalRiver.js on your page
Include the following script on the pages where you want it to appear (for example, the Cart or My Account page): 
<script type="text/javascript" src="https://js.digitalriverws.com/v1/DigitalRiver.js"></script>
Step 2: Include the base Drop-in CSS file
Include the following link to the Drop-in CSS file on the pages where you want it to appear (for example, the Cart or My Account page). If you'd like to customize the styles, simply override the Drop-in CSS file with your own. 
 <link rel="stylesheet" href="https://js.digitalriverws.com/v1/css/DigitalRiver.css" type="text/css"/>
Step 3: Initialize DigitalRiver.js with your public key
Initialize the DigitalRiver.js library with your public API key and any optional parameters. If you provide a locale, Drop-in will localize the experience accordingly.
let digitalriver = new DigitalRiver("YOUR_PUBLIC_API_KEY", {
     "locale": "en-US"
});
Step 4: Create a container for Drop-in
Create a container element for the Drop-in and place it on the page where you want it to appear within your experience.
<div id="drop-in"></div>
Step 5: Create a Configuration object for Drop-in
Create a configuration object. The object contains both required and optional values.
The following table lists the parameters for the configuration object.
Parameters

    billingAddress: {
        firstName: "John",
        lastName: "Doe",
        email: "[email protected]",
        organization: "Digital River",       
        phoneNumber: "000-000-0000",
        address: {
            line1: "10380 Bren Road W",
            line2: "",
            city: "Minnetonka",
            state: "MN",
            postalCode: "55343",
            country: "US"
        }
    },
    onSuccess: function (data) { },
    onCancel: function(data) { },
    onError: function (data) { },
    onReady: function(data) { }
}
Step 6: Use the Configuration object to create an instance of Drop-in
 Create an instance of Drop-in by passing the Configuration object using the createDropin() function.
let dropin = digitalriver.createDropin(configuration);
Step 7: Place Drop-in on your Cart or Shopper page
Add the following statement to your Cart or Shopper page:
dropin.mount("drop-in");
Using Drop-in within your Cart flow
Finalize your order totals
Create a checkout and provide the necessary information to have a final total for all amounts including taxes, shipping, duties, and fees. 
Initialize and place Drop-in within your application
Follow the instructions in Getting started.
From the experience page where you added the Drop-in container, customers select how they want to pay. Drop-in provides what is needed, including redirects to return a payment source that can be used in downstream API calls with the Commerce API.

The customer provides payment details
The customer may be redirected to authorize their payment. 
The onSuccess event returns the source
The following source object contains the customer's payment details for a one-time charge.
{
    "source": {
        "clientId": "gc",
        "channelId": "drdod15",
        "liveMode": false,
        "id": "9ddf3f08-7c56-4ce6-88b3-aee6cabe54a5",
        "clientSecret": "9ddf3f08-7c56-4ce6-88b3-aee6cabe54a5_46b96409-e4f1-457e-aed9-d273e2d0c0bd",
        "type": "creditCard",
        "reusable": false,
        "owner": {
            "firstName": "John",
            "lastName": "Doe",
            "email": "[email protected]",
            "organization": "Digital River",                 
            "phoneNumber": "555-000-0000",
            "upstreamId": "e1cd9cf0-2d19-49e2-9455-d89836a2b880",
            "address": {
                "line1": "10380 Bren Road West",
                "line2": "",               
                "city": "Minnetonka",
                "state": "MN",
                "country": "US",
                "postalCode": "55343"
            },
        },
        "state": "chargeable",
        "creationIp": "10.81.3.84",
        "createdTime": "2020-08-27T02:05:04.557Z",
        "updatedTime": "2020-08-27T02:05:04.557Z",
        "flow": "standard",
        "creditCard": {
            "brand": "MasterCard",
            "expirationMonth": 10,
            "expirationYear": 2030,
            "lastFourDigits": "5454",
            "fundingSource": "credit"
        }
    },
    "readyForStorage": false
}
Optional. Allowing the customer to save their payment details
During the cart flow, you may want to offer the customer the ability to save their payment details to use for future purchases. You can offer this via Drop-in. When using this solution, you must ensure that you collect the details your customer provides in a compliant manner and display required Strong Customer Authentication (SCA) prompts. You may access this mode by enabling the showSavePaymentAgreement option when configuring Drop-in.
let configuration = {
    sessionId: "YOUR_SESSION_IDENTIFIER",
    options: {
        showSavePaymentAgreement: true
    },
    billingAddress: {
        firstName: "John",
        lastName: "Doe",
        email: "[email protected]",
        organization: "Digital River",                
        phoneNumber: "000-000-0000",
        address: {
            line1: "10380 Bren Road W",
            line2: "",
            city: "Minnetonka",
            state: "MN",
            postalCode: "55343",
            country: "US"
        }
    },
    onSuccess: function (data) { },
    onCancel: function(data) { },
    onError: function (data) { },
    onReady: function(data) { }
}
When you enable this mode, the cart displays an optional check box that the customer must select when they agree to save their payment details on their account. 
If the customer selects the check box and clicks the Add Payment button, Drop-in performs the required authentication and marks the source as ready for storage. When the source is ready for storage, the onSuccess event returns the readyForStorage value.
The readyForStorage identifier signifies the creation of the source with the intention of storage, and any necessary authentications have occurred. To reuse the source, attach it to a Shopper by calling the appropriate API with your secret key.
Using Drop-in to collect payment details on a My Account page
Initialize and place Drop-in within your application
Follow the instructions in Getting started. You do not need to provide your sessionId in your Configuration object. Instead, you should provide a flow variable that tells Drop-in you are collecting details for future use.
let configuration = {
    options: {
        flow: "managePaymentMethods"
    }
    billingAddress: {
        firstName: "John",
        lastName: "Doe",
        email: "[email protected]",
        organization: "Digital River",          
        phoneNumber: "555-000-0000",
        address: {
            line1: "10380 Bren Road W",
            line2: "",
            city: "Minnetonka",
            state: "MN",
            postalCode: "55343",
            country: "US"
        }
    },
    onSuccess: function (data) { },
    onCancel: function(data) { },
    onError: function (data) { },
    onReady: function(data) { }
}
The Customer provides payment details
As part of collecting payment details for future use, the customer may be presented with Strong Customer Authentication and may also be required to agree to specific terms of storage. These details will automatically be displayed and collected to ensure compliance.
The onSuccess event returns the source
This flow presents and collects any required authentications and opt-ins. When the source collects the customer's payment details, authentication details, and opt-ins, the onSuccess event will return this information with a "readyForStorage": true parameter.
The readyForStorage identifier signifies the creation of the source with the intention of storage, and any necessary authentications have occurred. To reuse the source, attach it to a Shopper by calling the appropriate API with your secret key.

​ 
Specifying a source's future use
When creating a source using Drop-in, you should identify the types of transactions the source will likely be used for in the future. This increases the probability that these future transactions will be approved. The usage value you select should be the one that mostly closely corresponds to your business model. The available options are subscription, convenience, and unscheduled.
Subscription
Set usage to subscription when you create sources that are used primarily for recurring transactions, made at regular intervals for a product or a service.
Convenience
The convenience setting applies mainly to saved payment sources that are used for one-off transactions. These are sources where customers are typically present during the checkout flow and want to quickly access their payment information. Select this option if you don't offer subscriptions or don't have unscheduled merchant initiated transactions
Unscheduled
Set usage to unscheduled when you create sources for unscheduled merchant initiated transactions. These are contracts that occur on a non-fixed schedule using saved card information. Automatic top-ups are an example of one such transaction. They occur whenever a customer's balance drops below a pre-defined amount.
Configuring payment methods within Drop-in
Drop-in uses DigitalRiver.js elements to capture secure payment details. Drop-in comes with a predefined style that should meet most use cases. In the event you would like to customize the look and feel, you should familiarize yourself with the Styling an element container in the DigitalRiver.js documentation.
Here is an example of customizing several payment methods:
const apiKey = 'YOUR_PUBLIC_API_KEY';
 
digitalriver = new DigitalRiver(apiKey, {
    "locale": "en-us"
});
 
const configuration = {
    sessionId: 'd6deb2b4-347e-431e-9d56-095038e0e338',

The enabled list will not add any payment methods that are not available for the payment session.

Variable
Value
Description
source
A payment source
The created payment source.
readyForStorage
true/false
Indicates whether the source has been enabled for future use. 
Important: If this value is true, it does not mean the customer can use this source multiple times. This flag identifies whether the necessary downstream actions have been triggered to prepare the source for storage. You must attach the source to your customer for it to be truly reusable.
onError
If an error occurs, Drop-in emits an event that identifies the payment method associated with the error. Instruct your customer to provide a new method of payment.
{
    "paymentMethod":"googlePay"
}
onCancel
When your customer chooses to pay with a specific payment method and decides to cancel during the redirect phase, Drop-in emits an event that identifies the cancelled payment method.
{
    "paymentMethod": "googlePay"
}
onReady
When ready, Drop-in will emit an event that contains a "paymentMethodTypes" array of the available payment methods.
{
     "paymentMethodTypes": [
          "applePay",
          "creditCard",
          "directDebit",
