Is there a Free JSON format for REST calls? Open specification

johanmattsson — Mon, 25 May 2026 15:34:44 GMT

Hi I will write a very small program for managing rest calls. The idea is to use JSON and maybe a format that other programs can understand. Is the Talend API Tester - Free Edition and option or is the file format proprietary? I need the format to be open and free. If no which format is best if the aim is to have something working in more than one program? Postman?

Hi @johanmattsson ,

I'm not sure if I'm following your question correctly but, JSON is a free format; is an open standard used to store and exchange data, very common in REST API implementations. If by "format" you mean the structure of the JSON file, you can write it in any shape you want - just making sure it has a valid JSON syntax. You can learn more about JSON here: https://www.w3schools.com/js/js_json.asp

Thanks!

I am thinking of making it work with more that one program. Doing export and imports from the Talend browser plugin for example.
