Introduction

Recurring payments enable businesses to automate subscription-based billing for their customers. Integrating recurring payments with PayPal API in a Spring Boot application allows you to handle subscriptions, ensure secure transactions, and provide a seamless payment experience. This guide explains how to configure and implement recurring payments using PayPal's Billing Plans and Agreements API in Spring Boot.

Steps to Implement Recurring Payments in Spring Boot

1. Set Up the PayPal SDK

To use the PayPal API, include the necessary dependency in your pom.xml:

2. Create a Billing Plan

The first step in implementing recurring payments is to define a billing plan. This plan specifies the subscription details, such as frequency, amount, and duration.

Example: Create Billing Plan Method

3. Activate the Billing Plan

Once the plan is created, it must be activated before use. PayPal requires the plan to be in the ACTIVE state.

Example: Activate Billing Plan

4. Create a Billing Agreement

A billing agreement links the billing plan to a specific customer.

Example: Create Billing Agreement

Practical Examples

Example 1: Handle Customer Redirection

Once the billing agreement is created, PayPal generates approval links for customer authorization. Redirect customers to the approval_url for consent.

Example 2: Execute the Billing Agreement

After customer approval, finalize the agreement using the token provided in the callback URL.

Conclusion

Recurring payments with PayPal API in Spring Boot simplify subscription management and ensure reliable billing processes. By configuring billing plans, activating them, and linking agreements to customers, you can enable automated payments seamlessly. Leveraging PayPal's SDK and APIs ensures secure, scalable, and efficient recurring billing in your Spring Boot application.
