Implementing One-Time Auto Payments Using PayPal Reference Transactions

Not all payment use cases are well-suited for recurring billing models or fixed subscriptions. You require the ability to charge consumers different amounts at different times without requiring repeated consent in many real-world circumstances, such as usage-based pricing, on-demand services, or postpaid billing.  PayPal Reference Transactions and PayPal API Integration Services are extremely helpful in this situation.

Businesses can create unique billing processes that go beyond conventional subscription models by utilizing PayPal’s robust API features.  You can design secure and easy payment solutions that meet your unique requirements with the help of these integration services.

In this tutorial, we’ll look at how to use Laravel, one of the most well-liked PHP frameworks, to set up PayPal Auto Pay (non-recurring).  This configuration allows you to:

• Allow users to authorize future payments just once.
• Flexibly charge them later without needing repeated approvals. 
• Avoid the limitations of fixed subscriptions.

Gaining an understanding of PayPal API Integration Services will enable you to scale your payment infrastructure effectively and safely, regardless of whether you’re creating a marketplace, SaaS platform, or on-demand service.

What Are PayPal Reference Transactions?

With PayPal Reference Transactions, businesses can charge a client more than once without needing to get their consent each time. Using a secure billing arrangement made during the original transaction, you can start future payments on the customer’s behalf after a one-time approval. Businesses that require flexible pricing, like usage-based services, one-click reorders, postpaid plans, or variable subscription models, may find this extremely helpful.

Reference Transactions don’t have a set time or amount, in contrast to conventional recurrent payments. Rather, they allow you to charge just when necessary, which makes them perfect for markets, on-demand services, and SaaS platforms. You must ask PayPal to enable this option on your business account, though, as it isn’t available by default.

Developers can create unique auto-pay solutions that are safe and easy to use by integrating Reference Transactions using PayPal’s REST APIs or SDKs and combining them with frameworks like Laravel.

Use cases:

• Wallet top-ups 
• Auto-charge for custom orders 
• Custom invoicing after service delivery 
• Wallet or credit-based systems

Step-by-Step: PayPal Auto Pay (One-Time Payments Anytime)

Step 1: Get Approval for Reference Transactions 

You’ll need to contact PayPal support and request access to Reference Transactions. Provide: 

• Business name 
• Reason for needing flexible payments 
• Examples of how charges will work 

Once approved, PayPal will enable this feature for your account. 

Set up PayPal NVP API Credentials in Laravel 

First, create a config file or use .env :

Create a paypal.php config file: 

Step 2: Redirect to Create Billing Agreement (Auto Pay Consent) 

Redirect flow: 

1. Customer approves a Billing Agreement (e.g., “Authorize Company X to charge me anytime”). 
2. You save the Billing Agreement ID. 
3. You use it to charge later. 

Example flow: 

User clicks “Setup Auto Pay.” 

• Redirect to PayPal with Billing Agreement Token request 
• User logs in and approves 
• You get a token back in the return URL 
• Execute and store the agreement ID 

This creates a billing agreement token. Use this controller method: 

Step 3: Save Billing Agreement ID 

When PayPal returns to your success URL, grab the Billing Agreement ID and store it:
