I have a collection in Postman which loads “payload objects” from a json file and want to make it run in newman from command like.

POST request

Body: of POST request I have got {{jsonBody}}

Pre-request Script: logically pm.globals.set("jsonBody", JSON.stringify(pm.iterationData.toObject()));

and a file.json file with this kind of “objects”:

[
    {
    "data": {
        "propert1": 24,
        "property2": "24__DDL_VXS",
        ...
    },
        {
    "data": {
        "propert1": 28,
        "property2": "28__HDL_VDS",
        ...
    }
...
]

Works like a charm in Postman.

Here is what I’m trying to run in cmd.

newman run \
-d file.json  \
--env-var access_token=$TOK4EN \
--folder '/vlanspost' \
postman/postman_collection_v2.json
