Important: NVP/SOAP is a legacy integration method. We accept new integrations and support existing integrations, but there are newer solutions. If you're starting an integration, we recommend our latest solutions.

The PayPal NVP/SOAP APIs provide a set of application programming interfaces (APIs) that let you add PayPal payment and transaction functionality to your business applications. The NVP/SOAP APIs offer interfaces that cover all aspects of complex business transactions, including invoicing services, notifications, subscription services, parallel payments, permissions services, and functionality to processes refunds.

The PayPal development life cycle

The high-level development life cycle is the same for all PayPal services. You incorporate PayPal transaction functionality into applications as follows:

  2. Integrate PayPal functionality to your website and mobile applications.
  3. Test your PayPal transaction routines.
  4. Go live with your application.
  5. Maintain and upgrade your app.

The PayPal developer process

Here's how you code, test, and deploy your PayPal applications:

  1. Use your existing PayPal account to log in to the PayPal Developer website, or create a new account by clicking the Sign Up button on this site.
  2. Familiarize yourself with how to make PayPal API calls, as described in the PayPal APIs Getting Started Guide.
  3. Create virtual sandbox accounts in the sandbox, as described in the PayPal sandbox Testing Guide.
  4. Use the correct endpoints and credentials for the environment and operations you're addressing.
  5. Refer to the integration documentation for guidance. You can also utilize the Express Checkout demo site.
