It is an API testing tool with a minimalistic yet functional interface that allows users to complete complex testing tasks on any device. Test REST, GraphQL, WebSocket, SOAP, JSON RPC, XML, HTTP, and HTTPS. Perform all HTTP request methods: GET, POST, PUT, PATCH, DELETE, HEAD, etc. Import by cURL, or from Swagger, OpenAPI, Postman, and YAML. Use advanced settings for efficient testing. \nYou are on the move without a laptop with just a mobile, and your dev team is preparing an important patch. Before you instruct your team to start functional testing on the new build, you would want to make sure no critical regression scenarios are breaking. What do you do? Wouldn’t it be great to be able to trigger a sanity API test suite on the go and get results?\nThis is once a more frequent one where it’s late at night, you logged off, and your dev team just sent you a new build. You want your offshore team to pick up testing as soon as they step in, and you want to make sure they work on a green build. Would you log in again at midnight? Or wouldn’t it be great if you could trigger your API sanity test suite from your mobile and get the status?\n\nThese are just a few scenarios where it would be great if you had access to run your API test suite without even opening your laptop, but there can be many more you might have experienced throughout your career. To solve this very problem, the handiest tool is API Tester. \n\nThis app is not only free but also offers advanced features that most apps available on the AppStore or Google Play do not offer. The significant features of this app are: \n- Supports any type of API: REST, GraphQL, SOAP, WebSocket, JSON RPC, XML, etc. \n- Building requests of any method like GET, POST, PUT, PATCH, DELETE, HEAD, etc.\n- Just like Postman, you can easily import pre-built collections from Swagger, OpenAPI, Postman, YAML, or by cURL.\n- There is a powerful GraphQL editor\n- TLS can be skipped, redirects can be disabled, timeouts are adjustable, and weak SSL verification is available.\n- There is a Response Search.\n- Global Variables are supported. \n- There are features to enhance your testing efficiencies, like Run All Requests or sending files from device storage, cloud, and remote server.","image":"https://gdm-catalog-fmapi-prod.imgix.net/ProductScreenshot/edc520ea-9521-4c59-a88b-6f6104f684bb.png","url":"https://www.getapp.co.uk/software/2062759/api-tester","@id":"https://www.getapp.co.uk/software/2062759/api-tester#software","@type":"SoftwareApplication","publisher":{"@id":"https://www.getapp.co.uk/#organization"},"applicationCategory":"BusinessApplication","aggregateRating":{"@type":"AggregateRating","ratingValue":5.0,"bestRating":5,"ratingCount":2},"offers":{"price":"0","@type":"Offer","priceCurrency":"USD"},"operatingSystem":"Apple, Android, Platform ios, Platform ipad"},{"@id":"https://www.getapp.co.uk/compare/111387/2062759/lambdatest/vs/api-tester#breadcrumblist","@type":"BreadcrumbList","itemListElement":[{"name":"Home","position":1,"item":"/","@type":"ListItem"},{"name":"Automation Testing Tools","position":2,"item":"/directory/389/testing/software","@type":"ListItem"},{"name":"TestMu AI vs API Tester","position":3,"item":"https://www.getapp.co.uk/compare/111387/2062759/lambdatest/vs/api-tester","@type":"ListItem"}]}]}
