Checkout v2 Auth

Simple & Secure

Workbench
Sample Code

Overview

Offload the burden of hosting your own payment form and reduce your PCI scope with Forte's third-generation Checkout. Checkout's advanced features enable you to make quick and painless payments on your own site with just a few lines of code.

With Checkout you get:

  • A simple integration
    Start using Checkout today with customizable JavaScript that sits on top of your existing site.
  • Wallet storage functionality
    Save customer and payment method data to make checking out fast and easy.
  • Up-to-date customer data
    Enable customers to edit their own address and payment data to ensure you always have the correct information.
  • Advanced form field settings
    Default Checkout’s form fields to a value, empty, or hidden for full control over the data collected.
  • Granular amount settings
    Specify a non-editable amount to pay or a range of amounts for the customer.
  • Reduced cart abandonment
    Ensure your customer’s trust by running the entire checkout process from your site.

User Experience

Checkout’s Pay Now button uses an HTML form POST action with a signature to create the modal window. When the customer clicks the button with coded parameters on the client side, Forte servers read the parameters and populate the modal window. The JavaScript, https://checkout.forte.net/v2/js, includes a Forte name-spaced version of jQuery so as not to conflict with other client-side jQuery code.

Browser Compatibility

Checkout supports the three previous versions of the following browsers on a rolling basis:

Each time a new version of one of these browsers is released, Checkout begins supporting it and continues to support the previous two versions (and only the previous two). For example, if Checkout is currently supported on versions 9, 10, and 11 of a particular browser, when there is version 12 of this browser released, Checkout will support versions 10, 11, and 12 and will no longer support version 9.

This compatibility standard enables Checkout to use the latest and greatest security and performance features of the newest, most up-to-date browsers.

Merchant Configuration

Before coding the Pay Now button, you must set up a test account and perform the following tasks:

  1. Generate an API Access ID
  2. Generate an API Secure Key

Only these values are required for Checkout. The Secure Web Pay configuration options do not affect Checkout.

Generating Keys

Requests to Checkout require a hashed signature for authentication. This signature is created using your unique credentials, including a private key that you'll use when hashing signed elements. To integrate with Forte Checkout v2, use Forte’s Dex application to create your API credentials. For more information on creating a hash signature, see the Authentication section.

Complete the following steps to generate your API Access ID and API Secure Key:

  1. Log into your Dex Account.
  2. Search for and select the Home Organization for which you want to create the credential set. If your Home Organization is the same as your Logged-In Organization, skip this step.
  3. Select Developer > API Credentials from the Dex Main Menu.
  4. Click . The Create API Credentials screen displays.
  5. Enter a name for this set of API credentials in the Name Field. This field is required.
  6. Click . The API Access ID and API Secure Key values display in their corresponding fields.
  7. Click  next to the API Access ID and API Secure Key fields to record both of these newly generated values in a secure location to use in authenticating your requests.

NOTE: Once you save your API Secure Key, you will not be able to see the value again. If you forget your API Secure Key or it becomes compromised, you will have to regenerate the value in Dex.

Authentication

Checkout uses hash signatures for authentication.

Creating a Signature

The example below displays what information your signature should contain:

HMACSHA256("api_access_id|method|version_number|total_amount|utc_time|order_number|customer_token|paymethod_token",
"API Secure Key")

Use the following parameters when creating your hash signature:

Parameter

Description

Type

api_access_id

The organization-specific API Access ID value that you created in Dex. See the Merchant Configuration for information on creating this value.

string

method

Supported types include the following:

sale
schedule
token
auth

string

version_number

2.0

string

total_amount

A string that represents the total amount of the transaction. NOTE: The total amount must be sent as a string as the button parameter. A possible side effect of total_amount being sent as a number is seemingly random, intermittent authentication failures.

string

utc_time




A date-time value (since 01/01/0001 00:00:00) that marks the day and time the request was sent to Checkout in ticks. Checkout will only accept utc_time values that are 20 minutes before the current time or 10 minutes after the current time. Requests expire after 10 minutes to prevent malicious users from capturing requests and resubmitting them at a later time.

Checkout provides an API that returns the correct UTC time from Forte’s server. Using this server-side value prevents inadvertent expiration errors from client PCs that do not have the correct local time set.

Use the following get UTC API URLs in your code to retrieve UTC ticks from Forte's servers:

• https://checkout.forte.net/getUTC?callback=? //production
• https://sandbox.forte.net/checkout/getUTC?callback=? //sandbox
The following script returns the correct UTC time for the hash:



<script> var button = $('button[api_access_id]'); $.getJSON('https://sandbox.forte.net/checkout/getUTC?callback=?').done(function (utc) { button.attr('utc_time', utc); }); </script>



You can also use the following PHP/Curl code sample to fetch the UTC time from the getUTC API URL displayed above (e.g., ?(XXXXXXXXXXXX643793); where XXXXXXXXXXXX643793 is the UTC time value).

<?php
function utc() {
$curlUTC = curl_init();
curl_setopt($curlUTC, CURLOPT_URL, 'https://checkout.forte.net/getUTC?callback=?');
curl_setopt($curlUTC, CURLOPT_BINARYTRANSFER, true);
curl_setopt($curlUTC, CURLOPT_RETURNTRANSFER, true);

$curlData = (curl_exec($curlUTC));
$positionOfOpeningParenthesis = stripos($curlData,"(");
$positionOfClosingParenthesis = stripos($curlData,")");
$utc = substr($curlData,$positionOfOpeningParenthesis+1,$positionOfClosingParenthesis-2);
return $utc;
curl_close($curlUTC);
}

string

order_number

A string that represents the order number associated with a transaction.

string

customer_token

An alphanumeric ID used to reference a customer. Forte stores the token and its associated information.

string

paymethod_token

An alphanumeric ID used to reference stored payment information (card or eCheck) for a customer. Forte stores the token and its associated information.

string

Send the hashed values in signature parameter, a character string of varying length (depending on the hash method) that is used to represent a specific transaction for a specific merchant in Forte Checkout.

NOTE:

  • * indicate the default value of the parameter
  • Scheduling parameters require the merchant to pass predefined customer and payment tokens or set save_token=true.
  • When passing a customer token or creating a schedule, the shipping address can only be edited; a new address cannot be added.

Attributes

To make these parameters editable, required, or hidden, pass the parameter suffixed with attr and one or more of the following attributes:

Attribute

Description

Example

edit

Makes the field editable for the customer

a. billing_name_attr="edit"
b. billing_name_attr="edit,required"

required

Makes the field required for the customer

a. billing_postal_code_attr="required"
b. billing_postal_code_attr="edit,required"

hide

Hides the field from the customer; however, Checkout passes the parameter with the transaction behind the scenes. This attribute cannot be combined with the edit or required attributes.

billing_name_attr="hide"

Configuring Amounts

Checkout supports a number of different amount configurations including the following:

  • Single Amount greater than zero
    • The merchant specifies the amount
    • The customer specifies the amount
  • Ranged Amount
    • The customer must enter an amount between merchant-specified values greater than zero
  • Selection
    • The customer must select different merchant-specified values that include descriptive text
  • Range and Selection
    • The customer must select different merchant-specified values or can enter an amount between merchant-specified values

The sections below detail the attributes merchants can use to customize amounts.

Creating Editable Amounts

To provide an Amount field in which a user can enter his or her own amount, you must specify the "edit" attribute when passing the total_amount parameter (i.e., total_amount_attr="edit"). See Coding the Button for information on specifying attributes. The figure below displays an editable field:

NOTE: For ranged and selection amount configurations, Checkout ignores the “edit” attribute unless the merchant also specifies a default amount value.

Specifying Default Amounts

Merchants can define default amounts for their customers for ranged and selection configurations. To define a default, simply add the semi-colon and the amount to the end of the total_amount parameter (e.g., to define a ranged amount configuration that defaults to $5.00, use the following: (total_amount="1-10;5"). The figure below displays a default amount within a ranged configuration:

Using Amount Labels

For selection configurations, merchants can define descriptive text for the different amounts (e.g., Total Outstanding Balance, Statement Balance, Minimum). To add descriptive text, simply add it to the total_amount parameter (e.g., total_amount={1375.23, 1573.66, 56.99,0|Total Outstanding, Last Statement Balance, Minimum Balance, Specify Different Amount};500). The figure below displays Checkout with descriptive text:

Working with Scheduled Amounts

When scheduling transactions for customers, Checkout only supports the single or ranged amount configurations (e.g., total_amount="50" or total_amount="1-10;5"). The merchant can also make the total_amount parameter editable so that the customer can define his or her own amount. NOTE: When scheduling, the total_amount parameter cannot contain amount selections or amount labels.

Amount Values, Defaults, and Attributes Configurations

The following sections define all the potential amount configurations available in Checkout. They also detail whether or not the Total Amount field can be rendered editable, whether the merchant can add a default value, and provide an example of Checkout for reference. See Coding the Button for sample code containing various amount configurations.

Working with Procurement Cards

Forte Checkout supports procurement card transaction processing using EMV-only credit card terminals. EMV terminals require Forte Device Handler. For more information, contact Technical Support.

To enable EMV functionality, you must first pass the swipe=EMV-1 parameter in the Forte Checkout button code. At the time of the transaction, the customer will select the This is a Procurement Card check box on the Checkout modal and then enter the required Account Code and, if not passed in the tax_amount parameter, the Tax Amount.

Configuring AVS Checks

Forte Checkout supports Address Verification Services for credit card saleand auth transactions that occur in the United States (i.e., billing_country=US). These settings can be configured in Dex by the Admin of your organization. Merchants can choose the following AVS settings for their transactions in Forte Checkout:

  • Don't perform AVS checks
  • Check AVS but don't decline on mismatch
  • Check AVS and decline on mismatch

For more information on configuring these settings, see Working with Card Services Settings in the Dex Merchant Help documentation (if you're a partner, click here for the Dex Partner Help documentation).

Mobile Support

Checkout supports transactions on both tablets and mobile phones.

Callbacks and Webhooks

Checkout's callbacks and webhooks both contain the results of a transaction. Callbacks, however, provide real-time (synchronous), client-side notifications to you while webhooks provide asynchronous server-side notifications.

Using Callbacks

Callbacks provide your front-end with synchronous updates about the current state of the checkout process, which can then be relayed to the customer through the shopping cart (via a receipt display) or other applications integrated with Checkout. The button supplied to you contains a callback attribute that accepts and displays notifications for the following transaction events:

  • begin - This event occurs when the customer launches the payment button. You can use this event for conversion tracking data.
  • success - This event indicates that the transaction was successful.
  • failure - This event indicates that the transaction has failed. Inspect the response_code response parameter for more information (e.g., you are over your monthly processing limit (U04)). See Response Codes for more information. NOTE: If you attempt an ad-hoc transaction while passing the save_token=true parameter and the transaction fails, Forte will not return the token in either the callback or the webhook.
  • error - This event indicates that the request is invalid and Checkout could not be rendered. For example, triggers for this event could include a client failing to pass a valid authentication signature, an invalid total amount, or an invalid client token.
  • abort - This event indicates that the customer canceled the checkout process by clicking on the Close button on the modal.
  • expired - This event indicates that the customer failed to complete the transaction prior to the expiration time set by you via the expire_utc parameter.

Response Parameters

The table below details the response parameters that could be included in Checkout's callbacks.

Understanding Callback Parameters

The following table provides the callback parameters for events that occur in simple sales and scheduled transactions. The successful processing of a transaction triggers success event callbacks, which contain the result of the transaction (i.e., approved transactions). When an error event triggers a callback, the Checkout window displays the error message. Since some parameters are unavailable for some responses, those parameters may not be present in the response object.

NOTE: The "Returned Parameters" column contains example hash data.

Capturing Callback Messages

Callback messages enable you to present the customer with real-time status information on the transaction. To do this, you must capture the message by coding the callback attribute into your button:

				
					<!DOCTYPE html>
<script type="text/javascript" src="https://sandbox.forte.net/checkout/v2/js" data-rocket-defer defer></script>
<button api_access_id="apiaccessid"
	method="sale"
	version_number="2.0"
	utc_time="UTCtime"
	order number="ASX458956"
	callback="oncallback"
	signature="sha256signature">
	Pay Now</button>

This button code defines that your page will use the oncallback Javascript function to capture the callback message. To display the message to the customer after a transaction, you must add JavaScript to parse e.data to an HTML place holder:

				
					<head> 
	<script src="scripts/jquery-1.11.0.min.js" data-rocket-defer defer></script>
	<script type="text/javascript" src="https://sandbox.forte.net/checkout/v2/js" data-rocket-defer defer></script>
	<script>window.addEventListener('DOMContentLoaded', function() {
		function oncallback(e) {
			$('#message').html(e.data);
		}
	});</script>

The e.data response object is a string that can be converted to a JSON object with a format that you define with Checkout’s response parameters (see Response Parameters for more information). The sample code below shows how you could use this response object to capture a callback message for customers:

				
					<script>
	function oncallback(e) {
		var response = JSON.parse(e.data);
		switch (response.event)
		{
	case 'begin':
		//call to forte checkout is successful
		break;
	case 'success':
		//transaction successful 
		//(optional) validate from response.signature that this message is coming from forte
		//display a receipt
		alert('thanks for your order. the trace number is ' + response.trace_number);
		break;
	case 'failure':
		//handle failed transaction            
		alert('sorry, transaction failed. failed reason is ' + response.response_description);
	}
		}
		</script>

Using Webhooks

NOTE: Currently, Forte IT must configure webhooks.

Webhooks send asynchronous messages about a transaction directly to a server-side URL endpoint that a merchant defines. A webhook fires after all manually completed transaction requests. Forte notifies merchants about events through subscriptions. Depending on these subscriptions, multiple events can occur during an operation. For example, a credit card sale transaction that creates tokens for a customer and a paymethod causes three events to be fired: transaction.sale, customer.create, and paymethod.create. These three events can be combined under a common event ID (e.g., evt_xxxxxx) for easier information management. NOTE: Depending on how you configure your event subscriptions, the same data may be generated twice in separate webhooks. For example, creating a customer and including a paymethod could (if subscribed) generate a customer webhook with both customer and paymethod data as well as a paymethod webhook. You can subscribe to the following events in version 2 and version 3 webhooks:

  • transaction.sale
  • transaction.authorize
  • customer.create
  • customer.update
  • paymethod.create
  • paymethod.update

The following events are only supported in version 3 webhooks:

  • schedule.create
  • schedule.update

NOTE: Transaction voids, credits, and updates to individual schedule items must be completed using the appropriate version of Forte's REST API.

If a webhook post fails (i.e., does not result in an HTTP 200 response), Forte retries the webhook post up to twenty times, adding one minute for each retry.

The following code sample displays the fields of a transaction.sale webhook. NOTE: This webhook originates from the same call used in the success row of the callback parameters table above.

For more information on Webhooks, see Using Webhooks.

Service Fees and Webhooks

For ad-hoc transactions, most credit card service fees in Checkout are automatically calculated and then added to the total amount prior to authorization. Forte returns the service_fee_amount response parameter in both the callback and webhook for keyed (swipe=false), swiped (swipe=true or edynamo), and dipped (swipe=EMV-1 or edynamo) transactions. Below is the raw body of a sample webhook for a service fee transaction:

In addition to credit card service fees defined by your configuration, Checkout also supports the Visa Tax Program. You can process VISA debit card transactions via manual entry, tokens, schedules, or using credit card readers, including EMV-enabled terminals. Checkout automatically detects VISA Debit cards when you use manual entry (swipe=false) or credit card swipers (swipe=true, swipe=edynamo). However, to process Visa debit transactions using an EMV Verifone terminal, you must pass the swipe=EMV-1 parameter and the debit_card=true parameter to ensure Checkout charges the correct $3.95 service fee. If you pass debit_card=false Checkout charges the default credit card service fee. If you leave the debit_card parameter empty, checkout allows the cashier or user to manually indicate whether they are presenting a VISA debit card by clicking a box.

Using Point-of-Sale Devices

If the swipe parameter is set to true (see Coding the Button), Forte provides the user a button to not swipe if the merchant does not have available hardware. If swipe=EMV-1 in the button code and you have the Device Handler installed, Forte Checkout supports the V400C in hybrid mode for EMV card reading on Sale and Auth transactions.

Checkout supports the following types of credit card POS devices for ad-hoc and scheduled payments:

• Dynamag #21073062 v.1

• eDynamo #21079802

If swipe=edynamo, then the connection_type parameter is required. The eDynamo swiper supports both EMV and card swipes.

Creating EMV-Compliant Receipts

Merchants must create EMV-compliant receipts for all EMV sale and authorization transactions. The data required to print the receipt can be found in the transaction response data from the Forte Checkout callback (items with angle brackets contain the callback field name, e.g., <terminal_number>). The fields listed below are minimum requirements, but formatting is allowed.
