How to Integrate PayLexer with WP Travel Engine

WP Travel Engine is a WordPress plugin for tour operators, travel agencies, and activity providers. It enables you to manage bookings, itineraries, and trip packages directly from your WordPress site. PayLexer integrates with WP Travel Engine to handle secure payment processing across multiple gateways - Stripe, AmwalPay, and more.

Supported Features

• One-time payments - Accept full payment for a booking in a single transaction.

• Partial payments – Allow customers to pay a deposit upfront and settle the balance later.

• Multiple payment gateways and websites – Connect and manage several gateways and websites from one PayLexer account.

• Test mode via Debug Mode – Safely test payments without real charges before going live.

• Live payments – Process real transactions securely once setup is verified.

Before You Start

Prerequisites

Make sure you have the following before starting:

• Configured Payment Gateway – Choose & configure a gateway →

• A PayLexer account. Create your account →

• Admin access to your WordPress site.

• WP Travel Engine installed and active. Download WP Travel Engine →

Setup Journey

If you haven't configured PayLexer yet, follow these steps in order before continuing:

Integration Steps

Customize Gateway Settings

Once a payment gateway is enabled, you can customize how it appears to your customers at checkout. This applies to all payment gateways - the steps below use Paddle as an example.

This is useful when you want to show a friendlier name to your customers. For example:

• Show "Credit Card" instead of "Paddle" or "Stripe" - most customers do not know the gateway name

• Translate the label for your audience - "Tarjeta de crédito" for Spanish, "Carte bancaire" for French

Go to WP Travel Engine → Settings → Payments and click the tab for the gateway you want to update - for example, Paddle. Each connected gateway has its own tab.

You can update the following field:

• Title - The name shown to customers when they choose a payment method at checkout. By default this is the gateway name (e.g., "Paddle"). Change it to something your customers will recognize, like "Credit Card" or "Online Payment".

Click Save Settings to apply.

Test Mode & Debug Mode

PayLexer supports full testing without real charges via WP Travel Engine's Debug Mode.

How Test Mode Works

1. Go to WP Travel Engine → Settings → Payments → General.

2. Turn ON Debug Mode.

When Debug Mode is ON:

• PayLexer uses your Test credentials from the Payment Gateway Configuration page.

• WP Travel Engine bookings are created normally.

• Payments are processed in test mode.

When Debug Mode is OFF, PayLexer uses your Live credentials instead.

Payment Flow Overview

A new PayLexer order is created for every payment attempt, including partial payments.

Next Steps: Test Transactions

After enabling gateways, validate the full payment flow before going live.

• Basic testing: Use WP Travel Engine's Debug Mode above to create bookings without real charges.

• Advanced testing (partial payments, refunds, multi-gateway): Follow the dedicated guide → Test Transactions & Platform Integration

Troubleshooting

Best Practices

• Always test with Test credentials before switching to Live.

• Enable webhooks for better reliability and real-time payment event syncing.

• Run one small real payment after going live to confirm everything works end-to-end.

Final Checklist

Before going live, confirm all of the following:

• Payment gateway tested successfully in Debug Mode

• At least one payment method enabled in WP Travel Engine

• Website status shows Active in PayLexer

• WP Travel Engine payment method set to PayLexer

• Live credentials added (not just test)

• Debug Mode disabled in WP Travel Engine
