Build Smarter with PayPal: New API Collections, Flows, and Testing Tools

Announcing the New PayPal Partner APIs Collection

We're excited to unveil a brand-new public collection designed to supercharge how platforms, marketplaces, and SaaS providers integrate with PayPal: the PayPal Partner APIs Collection. This collection offers a streamlined experience for partners looking to integrate with PayPal. This curated set of pre-configured API requests showcases the full power of PayPal’s Partner APIs — making it easier than ever to onboard merchants, manage payments, and handle compliance with confidence. Whether you're onboarding new sellers or configuring payment flows, these ready-to-use API requests help you move fast without sacrificing clarity or control.

Enhanced Checkout Flows with Postman Flows

We're also rolling out an improved PayPal Checkout experience using Postman Flows and reusable Flow Modules. These are a game changer if you’re building a PayPal integration or want to quickly build an AI Agent into your flow.

• Benefits include:
• No more writing custom scripts or glue code
• Easily model complex API sequences
• View real-time execution and results across your checkout flow
• Seamless integration with AI request blocks for building AI Agents into your flow

Save hours and gain confidence in your integration — all within Postman.

Dynamic Server-Side Shipping Callbacks

New to the collection: server-side shipping callback examples! These advanced features give platforms and merchants dynamic control over shipping options in real time — right before a buyer completes their purchase. This is part of PayPal’s advanced checkout capabilities and a must-use for teams focused on optimizing fulfillment workflows.

Built-In Error Simulation for Orders & Payments APIs

Testing edge cases? We’ve got you covered. Our Orders & Payments APIs now include built-in support for the API Error Simulator. Easily toggle error responses on or off to see how your app handles failures — no manual setup required.

Create Recurring Revenue with Our New Payment Flow

Want to build a recurring revenue model directly into your commerce app? Our new Flow walks you through creating a seamless, end-to-end recurring payment workflow using PayPal’s APIs. It's perfect for subscriptions, memberships, and any use case that benefits from reliable, repeatable payments.
