Which tool can be used to capture HTTP traffic for debugging?

Using HTTP Monitors is a highly effective approach for capturing HTTP traffic for debugging purposes. These tools are specifically designed to intercept and log the HTTP requests and responses that occur between a client and a server. This functionality is crucial for developers and integration architects, as it allows them to see the actual data being sent and received, including headers, body content, response times, and any potential errors.

The ability to analyze the captured traffic can greatly assist in identifying issues related to API calls, such as incorrect endpoints, authentication failures, or malformed requests. Additionally, HTTP Monitors can often provide features such as filtering, search capabilities, and customizable logging options, allowing users to focus on specific interactions and streamline the debugging process.

Other tools mentioned, such as Postman, are primarily focused on testing APIs rather than solely capturing traffic. While Postman can simulate HTTP requests and show responses, it does not provide the same comprehensive traffic monitoring capabilities as dedicated HTTP Monitors. YouTrack serves as a project management tool, and Data Loader is specifically used for data manipulation in Salesforce, neither of which are intended for traffic capturing. Therefore, using HTTP Monitors is the most suitable choice for debugging HTTP communications.
