Unlock Your Data: A Guide To REST API V2

Hey there! Let's dive into the exciting world of REST API v2 and how it can revolutionize the way you interact with your machines and their data. In the realm of software development, APIs (Application Programming Interfaces) act as the crucial messengers, allowing different software components to communicate with each other. While web sockets are fantastic for real-time, dynamic user interfaces, sometimes you need a more structured and script-friendly approach. That's where our enhanced REST API comes in! We're bumping up the API version to v2 to introduce some really neat features that will make your life so much easier, especially when you're dealing with machine data.

One of the biggest improvements we're bringing with REST API v2 is the concept of a 'slug.' Think of a slug as a human-readable nickname for your machines. Instead of dealing with complex serial numbers or technical identifiers, you'll be able to use simple, memorable names like 'winder' or 'buffer.' This makes your API calls much more intuitive and less prone to errors. Imagine you're constantly talking about the 'winder' – now, instead of typing out a long serial number, you can just refer to it by its slug. This is a game-changer for scripting and automation, where clarity and simplicity are key. This slug will be integrated directly into the API endpoints, streamlining your interactions significantly. For instance, when you query a 'winder,' you can expect to receive a WinderStateEvent – or, if that winder doesn't exist, you'll get a clear 404 Not Found error, which is much more informative than a cryptic failure.

We're proposing several new paths to make data access and manipulation more efficient. First up, you'll be able to easily get a list of all your machines with GET /api/v2/machine. This is your go-to endpoint for an overview of your connected devices. Once you have your machine's slug and serial number, you can effortlessly fetch its current state and live values using GET /api/v2/machine/<slug>/<serial>. This endpoint is designed to give you an immediate snapshot of what your machine is doing right now, including all the critical live data points. Think of it as the pulse of your machine, readily available at your fingertips. This immediate access to real-time data is invaluable for monitoring, diagnostics, and making quick operational decisions. The use of slugs here ensures that even if the underlying serial number changes or is complex, your script can continue to function flawlessly by referencing the stable, human-readable slug. This robustness is a core principle behind REST API v2, aiming to reduce maintenance overhead and increase the reliability of your integrations.

Furthermore, REST API v2 provides a dedicated endpoint to retrieve the default state of any machine: GET /api/v2/machine/<slug>/<serial>/default. This is incredibly useful for resetting your expectations or for troubleshooting. If you ever need to know what a machine's standard configuration or baseline settings are, this endpoint has you covered. It helps in understanding the machine's intended behavior and comparing it against its current operational state. This historical context is vital for identifying deviations and understanding the root cause of any issues. The distinction between the current state and the default state allows for a more nuanced analysis of machine performance and configuration drift over time. For developers and operators alike, having this clear demarcation simplifies troubleshooting and ensures that configurations are managed effectively. The inclusion of the <slug> in these endpoints further solidifies the user-friendly nature of this API version, making it easier to integrate into various workflows.

For those who need to analyze trends or look back at past performance, the history endpoint is a lifesaver. With GET /api/v2/machine/<slug>/<serial>/history, you can retrieve all cached live value events for a specific machine. This allows for comprehensive data analysis, performance tracking, and the identification of long-term patterns. Imagine being able to plot the performance of a 'winder' over the past week or month; this endpoint makes that a reality. Understanding historical data is crucial for predictive maintenance, optimization efforts, and ensuring consistent quality. This feature goes beyond simple monitoring; it empowers you to gain deep insights into your machine's operational lifecycle. The ability to query historical data through a simple and well-defined API path like this significantly enhances the utility of the data you collect. It transforms raw data into actionable intelligence, enabling proactive management and strategic planning. The consistent use of slugs across all these history-related endpoints ensures that your data retrieval processes remain robust and easy to manage.

We also understand that you need to control your machines, not just monitor them. That's why REST API v2 introduces a powerful mutation endpoint: POST /api/v1/machine/<slug>/<serial>/mutate. While we're keeping the path under /api/v1/machine/ for now to leverage existing mutation logic, we're making it more flexible. You'll be able to send a list of mutations in a single POST request, rather than just one at a time. This significantly simplifies your scripts and reduces the overhead of making multiple API calls. Need to adjust the speed and change the mode of your 'buffer' simultaneously? Now you can do it in one go! This batch mutation capability is a major efficiency booster, especially in automated workflows where timing and reducing network latency are critical. The ability to group related state changes into a single transaction not only speeds up operations but also helps in maintaining data integrity by ensuring that a series of changes are applied atomically or not at all, depending on the underlying implementation. This feature is a testament to our commitment to making REST API v2 as practical and efficient as possible for real-world applications, supporting complex control scenarios with ease.

Finally, to ensure transparency and ease of use, we are committed to providing comprehensive API documentation. We strongly recommend using the OpenAPI specification (formerly Swagger). OpenAPI provides a standardized, language-agnostic format for describing REST APIs. This means you can automatically generate documentation, client SDKs, and even test cases, making it incredibly easy for developers to understand and integrate with our API. Tools like Insomnia.rest can automatically test and document APIs based on OpenAPI specifications, further streamlining the development and testing process. Having well-documented APIs is not just a best practice; it's essential for fostering adoption and ensuring successful integrations. Clear documentation, coupled with the human-readable slugs and batch mutation capabilities, makes REST API v2 a powerful and user-friendly solution for managing your machine data and operations. We believe this will greatly enhance the developer experience and the overall utility of our platform.
