API Testing Tools is a fast, private HTTP client for your iPhone, set like a newspaper. Write a request, send it, and read the answer in clean type, with the timings, headers and checks that matter.
THE DAILY REQUEST
• A front page with today's sends, what needs your attention, your slowest endpoints and the requests you pin, ready to send in one tap.
REQUESTS
• Every method, query parameters, headers, and JSON, form, XML, text or GraphQL bodies.
• Bearer token, Basic and API-key authentication.
• {{Variables}} and environments: switch between staging and production in one tap. Built-in {{$uuid}}, {{$timestamp}}, {{$isoTimestamp}} and more.
• Paste a cURL command from docs or your browser, or import a Postman collection or environment.
RESPONSES
• Pretty-printed JSON that keeps the server's key order, raw text with search, image and HTML previews.
• Fields: every value in a JSON response with its path. Tap one to check it or save it into a variable.
• Status, size and where the time went: DNS, connect, TLS, waiting and download.
• Live streams: watch server-sent events arrive as they happen, with event names, ids and timings.
CHECKS AND CHAINS
• Checks on every response: status, response time, headers, body text and JSON paths.
• Save a value from a response into a variable, like a login's token, and use it in the next request.
• Run a whole collection in order and see at a glance what passed and what needs a look.
AND
• A history of every send with its full response, and a filter for what failed.
• Copy any request as cURL, or export it as HTTPie, JavaScript, Python, Swift or Go.
• Export and import your library as JSON.
• Self-signed certificates for local dev servers (optional), cookies, timeouts and redirects under your control.
• Light and dark editions.
Free, with no ads, no tracking and no account. Requests go straight from your iPhone to the servers you call; nothing passes through anyone else. An optional "Buy me a coffee" tip supports the developer and unlocks nothing.
Version 3.0 is a new app, set like a newspaper.
• The Daily Request: a front page with today's sends, what failed, the slowest endpoints and the requests you pin.
• Collections, environments and {{variables}}: Staging and Production are a tap apart.
• Checks on every response (status, time, headers, JSON paths), and values saved from one response into the next request, like a login's token.
• Live server-sent events, a timing breakdown for every send, and JSON fields you can tap to check or save.
• Paste a cURL command or import a Postman collection; export any request as cURL, HTTPie, JavaScript, Python, Swift or Go.
• Run a whole collection in order and see what passed.
• A history of every send with its full response, and a filter for what failed.
• Light and dark editions.
Your saved requests from version 1 are waiting in “My Requests”.
Still free, with no ads, no tracking and no account. If the app saves you time, there's an optional coffee tip in Settings.
