Debugging SDKs can be challenging due to the multiple layers of potential complexity, including the app using the SDK, the SDK itself, OpenAPI specs, documentation, API gateways, and backend APIs. Additionally, some API calls may be constrained by rate limits, cost, access restrictions, or required call sequences. To make debugging easier, tools like Proxyman can help inspect and manipulate HTTP(S) traffic, providing a clean interface for developers to see exactly what their SDK is sending and receiving. A real-world example demonstrates how Proxyman can be used to debug an SDK by intercepting requests, modifying responses, and simulating API calls with edge-case data or scenarios that are difficult to trigger naturally. By using tools like Proxyman, developers can build, test, and iterate on SDKs more efficiently, ensuring they are reliable, correct, and easy for developers to consume.
