API Zen is a user-friendly application designed for building and managing API requests easily. It features a simple and intuitive request composer that allows users to construct requests effortlessly and view responses clearly. The app supports a wide range of request components, including headers, request parameters, and different formats for the request body such as JSON, XML, raw input, and forms with file or image attachments. It also handles multipart and binary data, making it suitable for various API testing needs.
One of the key strengths of API Zen is its organization system, which allows users to manage endpoints effectively by grouping them into workspaces and projects. This organization helps maintain a tidy workspace, especially when dealing with multiple APIs or complex projects. Additionally, users can enable iCloud syncing for their workspaces, ensuring seamless access across devices. If the syncing feature is turned off, workspaces are stored locally only, providing flexibility based on user preferences.
The application supports smooth switching between local and iCloud-based workspaces, which enhances workflow flexibility. Users can also customize their request methods per project, tailoring their API interactions as needed. When it comes to responses, API Zen provides detailed information such as headers, cookies, connection metrics, and other response data. Responses can be viewed in raw format with syntax highlighting, or as a rendered HTML page, giving users multiple ways to interpret the data returned from APIs.
Additional features include maintaining response history for review, SSL validation options for each request, and environment groups with variable support within each workspace. Users can select different environments on a per-request basis, which is particularly useful for testing different stages of development. The app also supports dark mode for comfortable usage in low-light conditions. Import and export functions make it easy to back up or share workspace data. API Zen is free to use, with optional donations contributing to ongoing development efforts.
