About
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.
