To streamline developer adoption and ensure robust integration, PayPal partnered with Postman. Key speakers included Swapnil Sapar, Principal Engineer, and Madita Tuari, Senior Director of Developer Experiences, who detailed how they integrated Postman's platform for both internal API production and external developer onboarding. ## Detailed Analysis PayPal successfully optimized the developer experience by deeply integrating Postman tools, leading to a reduction in TTFC to one minute. This achievement stemmed from meticulous work on their public Postman collections, launched in April 2022, specifically targeting the speed of API invocation. The platform is used internally for API production and externally to expose services, fostering a collaborative, self-service environment. Madita Tuari highlighted that Postman collections and workspaces are now part of the company's daily language for API communication. By capturing every API behavior within these collections, PayPal ensures external developers achieve solid integrations that handle both positive and negative scenarios, thereby preventing transaction drops. The success is evidenced by the 30,000 forks on their public Postman collection as of the discussion, reinforcing PayPal's commitment to an API-first approach alongside Postman. ### PayPal's Mission and API Importance - Democratize financial services and educate customers - APIs move billions of dollars and are foundational to the business - Dropping a transaction is not an option ### Dual Use of Postman at PayPal - Used internally to produce APIs - Used externally via Postman's public network to offer services to outside developers - Single sign-on and SEIM are crucial for faster developer onboarding ### Impact of Postman Collections - Collections and workspaces became part of the everyday vocabulary for communicating about APIs - Used to remove friction in invoking APIs and understanding behavior - Allows developers to gain confidence to estimate integration effort ### Key Metric Achievement - Focused on getting from looking at APIs to invoking them faster - Achieved a TTFC down to 1 minute - Public collections launched in April 2022 and have 30,000 forks today ### Developer Experience Goals - Postman showcases APIs so developers can play quickly and interact with many APIs simultaneously - Enterprise platform is self-service but allows for collaboration - Goal is to ensure developers understand different ways PayPal APIs behave for quality integration
