Build and DynamicallyTest a Banking API with Agent Mode and Postman MCP Server
Blog post from Postman
The tutorial provides a comprehensive guide on creating an Intergalactic Banking API using Node.js, connecting it to Postman for automated test creation through Agent Mode, and integrating with Claude via the Postman MCP server for natural language interactions. The process involves setting up a local banking API to manage accounts and transactions, importing it into Postman to organize API requests, and utilizing AI-generated test scripts for validation. By leveraging Agent Mode, users can automate the creation of environment variables, update request URLs with collection variables, and dynamically capture and store API keys and account information for authenticated transactions. The tutorial further explores how to generate and run test scripts using the Collection Runner, enabling a seamless workflow with AI assistance. The integration with Claude allows for enhanced interaction with APIs through natural language processing, opening up possibilities for exploratory testing and AI-driven API management. The techniques demonstrated are applicable to production APIs beyond the tutorial's financial transaction context, offering a robust framework for building AI-ready APIs with automated testing and interaction capabilities.
