April '26 Highlights: Add Custom Code to SDKs, Create API Portals Using AI Agents, and Publish SDKs From the APIMatic CLI

APIMatic's latest platform update, released in April 2026, introduced several major enhancements, including the ability to inject custom logic, helper methods, and entire files into generated SDKs without losing changes upon regeneration. The update also launched APIMatic Skills, enabling users to manage their developer portal via natural language prompts with AI coding assistants like Claude Code and Codex, thus streamlining the development process. Moreover, SDK publishing has been integrated into the CLI for seamless CI automation, allowing for spec validation, generation, customization reapplication, and publishing to be automated in one flow. The update also included improvements in portal usability, such as configurable "Try It Out" options in different environments and expandable navigation options for better readability. These features aim to enhance the flexibility and efficiency of SDK customization and developer portal management, providing a more streamlined workflow for developers.
