It's a fast and simple process that can let you handle file transfers from anywhere. If you want to get started with the Filestack API, here's what you need to know: Specifying File Types and Size Limits The Filestack API enables you to specify exact file types, sizes, and formats for each file upload you perform. This ensures that your applications only accept valid files that meet these criteria. In order to do this, all you need to do is specify the limits in advance within your application code. This allows the Filestack API to quickly check each file for compatibility before it can be uploaded. Retrieving Files Programmatically with the Filestack API The other great thing about using the Filestack API is that it makes retrieving files programmatically quick and simple too. You can even use the same code as when uploading files—just use a different call type! Using this feature of the Filestack API allows you to quickly transfer large numbers of files between various systems without having to manually download or upload each one yourself. File processing with the Filestack API Once you’re set up with the Filestack API, you can start processing and transforming your files. The API supports a wealth of features, so here are some of the most popular: Transforming Images Using the Filestack API, you can perform basic image transformations, such as resizing, flipping, and rotating. The API also supports more advanced features like watermarking and face detection. For example, you could create a thumbnail from an uploaded image with just a few lines of code. Creating Thumbnails or Previews You can also easily create thumbnail or preview images for a file before it is uploaded to your system. This makes sure that users are only able to upload valid files and can view previews of their uploaded content before it goes live on your site. Converting Files to Different Formats The Filestack API can also convert between different file types and compress files if necessary (for example, converting from PDF to JPG). This helps ensure that the images being uploaded follow the best size and format for your application. Delivering files with the Filestack API Another awesome thing the Filestack API can do for you is to deliver files quickly and efficiently. It's so easy—you just embed objects (images, videos) into web pages or stream audio/video files with a single line of code. Embedding into web pages Embedding a file into a page is easy—all you need to do is auto-detect its type and convert it to the optimal format, then store it securely in the cloud. With the Filestack API, this becomes much simpler. When you're ready to add an image or video to your website, just start typing , and the Filestack system will automatically provide you with the right options for that particular file format. filestack Streaming audio/video files Streaming audio or video files can be tricky — it requires special formats like HLS or MPEG-DASH that can handle different device requirements and properly buffer files. But with the Filestack API, all those complex tasks are handled for you — no need to worry about encoding speeds or internet connection speeds; your file will be delivered in the optimal format every time. That way, your media always plays perfectly on any device – giving your customers the best possible experience. Security and authentication with the Filestack API It's important to make sure that your uploaded files are secure and protected, and the Filestack API makes it easy for you. You can set access control policies that restrict user access to filestack-hosted files. This helps ensure the safety of the file, since only those with the correct credentials can view it. In addition to access control policies, you can authenticate API requests with signed URLs. By signing your URLs with a secret Filestack API key, you can make sure that only purposes you trust are accessing your files. It provides an extra layer of security so that your files remain safe and protected from unauthorized access. To get started, all you need to do is generate an API key in your Filestack account, and use it in conjunction with Signing URLs to authenticate requests made against the Filestack API endpoint. It's simple but very effective in keeping your uploaded files protected! Best practices for using the Filestack API Once you've gotten your feet wet with the Filestack API, you'll want to start thinking more strategically about how to use it. To help you out, here are some best practices for using the Filestack API and optimizing its performance. Performance Considerations and optimization tips The Filestack API is designed to handle large amounts of data quickly, but there are still ways to optimize its performance: Set reasonable timeouts for your API requests so that long-running processes don't crash your application. Keep an eye on your API usage metrics. If a particular request is taking too long or draining resources, you can adjust it accordingly. Use caching whenever possible. Caching can drastically speed up processes and reduce API calls. Optimize files before using the API with tools like Image Vectorization or Compression. This will reduce loading times and keep files sizes small. Error handling and debugging strategies Nobody likes error messages, but they are an unavoidable part of using APIs (and software in general). The good news is that the Filestack API provides extensive debug logging and error handling protocols to help you get to the bottom of any issues quickly: Monitor all error messages in a central log file for easy reference when troubleshooting issues. Manage all errors from a single endpoint rather than having them scattered across your application codebase. Update your codebase regularly with bugfixes or new features that address errors as soon as possible. Using the parameter in API requests to get more detailed error messages in the API response. debug Checking the API documentation for known issues or limitations that may cause errors. Using the field in the API response to get more information about the error. error_details Scaling up usage of the Filestack API As you become more comfortable with the Filestack API, you may find that you need to scale up your usage in order to meet growing demand.
