I’m trying to integrate PayPal Payflow Pro with a Spring Boot application and have a few specific questions regarding the integration process:

1. PayPal SDK for Java:

I see that PayPal provides an SDK for Java, but I’m unsure how to integrate it with a Spring Boot application. Can anyone share guidance on how to integrate PayPal Payflow Pro into a Spring Boot project

2. Available REST APIs for PayPal Payflow Pro:

Does PayPal provide REST APIs for Payflow Pro, or do we need to rely solely on the SDK for integration? If REST APIs are available, where can I find the documentation to integrate them with Spring Boot?

3.Subscription-Based Plan with Profile Creation:

In my application, I need to implement a subscription-based payment plan. I understand that for each user, a profile needs to be created. However, passing credit card data through the API seems unsafe and could violate standards (such as PCI-DSS).

How can I manage subscriptions without directly handling sensitive credit card data?

Is there a way to create user profiles for subscription plans without passing credit card details through the API?

I’m planning to use PayPal’s checkout page for this, but any insights on how to securely create profiles without violating security standards would be helpful.

4. PayPal Payflow Pro Specific References:

Could someone provide references or documentation for implementing PayPal Payflow Pro with Spring Boot? I’ve found some resources online, but I want to make sure I’m following best practices for security, subscription handling, and user profile management.

Any help or code examples would be greatly appreciated!
