Single Entity API can perform Bulk operation using Postman

You can use data files to pass Postman sets of values to use in a collection run. By selecting a JSON or CSV data file in the Collection Runner, you can test your API requests with multiple values as part of a single run.

Best way to compare json files online

Compare json files online.

Problem statement: How can I compare whether two JSON objects are equal using online tool/website, disregarding the order of lists?

first_sample.json document:

{
    "errors": [
        {"error": "invalid", "field": "email"},
        {"error": "required", "field": "name"}
    ],
    "success": false
}
        

second_sample.json document:

{
    "success": false,
    "errors": [
        {"error": "required", "field": "name"},
        {"error": "invalid", "field": "email"}
    ]
}
      

'first_sample.json' and 'second_sample.json' should compare equal, even though the order of the "errors" lists are different.

Solution

Step as below

1. Sort both ('first_sample.json' and 'second_sample.json') file using Json sort online tool/website. ( json-sorter)
2. Comapre json file using online compare tool/website. (diffnow)
