Test Transactions & Platform Integration

Validate your end-to-end payment integration with a full test transaction before going live.

Overview

This guide walks you through testing your payment integration end-to-end before accepting real payments. The steps apply to all supported platforms.

The example below uses WP Travel Engine with Stripe - but the testing logic is identical regardless of which platform or gateway you are using.

Before You Start

Make sure you have completed all prior steps:

Configured Payment Gateway – Choose & configure a gateway →
PayLexer Account – Create your account →
Admin access to your WordPress site
Platform Integration Ready – Choose & complete platform integration →

Setup Journey

Getting Started – Complete setup guide →
Configure Payment Gateway – Choose & configure gateway →
Add Your Website – Add your site →
Platform Integration – Choose & connect your platform →
Test Transactions & Platform Integration – You're here! ✓

Step 1: Enable Test / Debug Mode

Turn on Test or Debug Mode

Enable Test Mode or Debug Mode in your integration platform.

For example, in WP Travel Engine: go to WordPress Dashboard → WP Travel Engine → Settings → Payments → General, ensure your payment gateway (e.g., Stripe) is checked, and click Save Changes.

This ensures:

Test credentials are used from PayLexer
No real money is processed

How to enable or disable Test / Debug Mode depends on your platform. Refer to your platform-specific integration guide for the exact steps.

Step 2: Complete a Test Transaction

Visit your website frontend

Open your website in a browser and navigate to a product, trip, or service listing.

Proceed to checkout

Select a product or service and proceed to the checkout page.

Select your payment gateway

In the payment section, select your configured payment gateway (e.g., Stripe) and enter test customer details.

Enter test payment details

Use the test card or payment details provided by your gateway. Each gateway publishes official test credentials:

Use your gateway's official test card numbers - never use real card details in Test Mode.

Complete the checkout

Submit the payment and wait for the confirmation page.

Expected results:

Checkout completes successfully
An order is created in your platform (e.g., a booking in WP Travel Engine)
The transaction appears in PayLexer with a Success status

If you successfully complete the checkout process, the Stripe integration is successfully integrated. You can also check WP Travel Engine bookings to confirm the transaction.

Step 3: Verify in PayLexer

Check PayLexer Orders

Correct amount
Correct payment gateway
Status: Success

Check the Customer record

Navigate to Customers in PayLexer and confirm the customer record was created correctly.

Common Notes on Transaction IDs

Different systems generate different IDs for the same payment - this is expected behaviour:

System	ID generated
Your platform (e.g., WP Travel Engine)	Booking ID / Order ID
PayLexer	PayLexer Order ID
Payment gateway (e.g., Stripe)	Transaction ID / Charge ID

All three IDs are linked to the same payment. Mismatched IDs are not an error.

Go Live - Start Accepting Real Payments

Once you have completed successful test transactions:

Disable Test / Debug Mode

Turn OFF Test Mode or Debug Mode in your platform.

Refer to your platform-specific integration guide for exact steps on disabling Test Mode.

Confirm live credentials are saved

Ensure your Live / Production credentials are saved in PayLexer's Payment Gateway Configuration. When Test Mode is OFF, PayLexer automatically switches to Live credentials.

Run one real transaction

Process one small real payment to confirm the live integration is working correctly before opening up to customers.

Your integration is now live and ready to accept real customer payments.

Troubleshooting

Check if webhooks are configured for your gateway
The order in PayLexer should show Success even if the platform shows Pending
Configure webhooks in your gateway to prevent this in future — webhooks push real-time status updates to your platform

Verify the PayLexer plugin is activated on your WordPress site
Check that the Client ID and Site Key are correctly entered in plugin settings
Ensure your website shows Connected in PayLexer → Websites

The gateway may not be enabled in PayLexer for this website
Credentials may not match the active environment (Test vs Live)
Check your payment gateway dashboard directly for the transaction record

This is normal. Your platform, PayLexer, and the payment gateway each generate their own IDs. All three are linked to the same underlying payment — no action required.

Best Practices

Complete at least 2–3 successful test transactions before going live
Test with different payment methods if your gateway supports multiple (e.g., card and mobile money)
Verify webhooks are working by checking that order statuses update automatically after payment
Confirm email notifications are being sent to customers
Review that the booking confirmation page looks correct for customers
