API Canvas
Read full descriptionHide full description
Your APIs don't stop needing testing when you step away from your desk. API Canvas brings a full-featured, native testing experience to iPhone and iPad—built from the ground up on Apple's Liquid Glass design language, not bolted onto a web wrapper. With API Canvas in your pocket, you have access to: ▶ Send Requests: Make HTTP calls using GET, POST, PATCH, PUT, or DELETE methods. ▶ Inspect Responses: Response bodies and headers are made easy to read and understand. Syntax highlighting makes HTML and JSON responses easy to read, even in dark mode. ▶ Stars & Collections: Mark your requests as starred or add them to a collection of your choice to make them easy to find. ▶ Import Requests: Bring in your request collection from Postman so you're not starting from zero. ▶ Request History: Your most recent requests can be found with the touch of a button. Re-run them at any time. Go Pro to unlock: ▶ Customize Collections: Bring your collections list to life by coloring each collection and adding an icon that suits your personality. ▶ Environment Variables: No need to update the auth token in every saved request when it changes. Write 'Bearer {{token}}' once, and update it across every request. ▶ Export Requests: Package up your API requests into a tidy little JSON file and send it over to Postman or keep it as a backup just in case. You worked hard to build your web service. Your APIs deserve a testing tool that works just as hard. ---- Privacy Policy: https://canadiancat.io/api-canvas/privacy Terms & Conditions: https://canadiancat.io/api-canvas/terms
