Steven Lott has been programming since computers were large, expensive, and rare. Working for decades in high tech has given him exposure to a lot of ideas and techniques, some bad, but most are helpful to others. Since the 1990s, Steven has been engaged with Python, crafting an array of indispensable tools and applications. His profound expertise has led him to contribute significantly to Packt Publishing, penning notable titles like "Mastering Object-Oriented," "The Modern Python Cookbook," and "Functional Python Programming." A self-proclaimed technomad, Steven's unconventional lifestyle sees him residing on a boat, often anchored along the vibrant east coast of the US. He tries to live by the words “Don't come home until you have a story.”

In many web service environments, mobile applications and JavaScript-based interactive front-ends will have certificates allowing access to the back-end.

In addition to SSL, another common practice is to require an API key as part of each transaction. An API key can be used to authenticate access. It may also be used to authorize specific features. Most importantly, it’s essential for tracking actual usage. A consequence of tracking usage can be throttling requests if an API key is used too often in a given time period.

The variations in business models are numerous. For example, use of the API key could be a billable event and charges will be incurred. For other businesses, traffic must reach some threshold before payments...
