Challenge

My biggest hurdle came when trying to obtain an access token for the Charles Schwab Market Data API. After spending weeks scouring online resources and attempting various solutions, I finally decided to reach out to the API's support team. This turned out to be a game-changer - by providing detailed information about my application and relevant code snippets, I received a solution almost immediately. This experience taught me a valuable lesson: when working with complex APIs, it's perfectly okay (and often more efficient) to engage directly with the development team rather than spinning your wheels.

Learning Python while racing against a deadline presented another significant challenge. As a JavaScript/React developer, I was excited to expand my skill set, but the learning curve was steeper than anticipated. Each debugging session and concept I had to learn meant another day closer to the deadline. The experience helped me better understand the importance of realistic timeline planning when working with new technologies.

A seemingly simple oversight - using a non-working callback URL - cost me nearly a week of development time. It was particularly frustrating because I had encountered (and solved) this same issue in a previous project. This experience reinforced the importance of maintaining a permanent callback URL through a reliable server (even a free one works great!) for API development. Most importantly, I learned that sometimes pushing past a deadline to ensure the API can truly deliver what the client needs is better than rushing to meet a deadline with incomplete functionality.
