its easy to run these tests in Postman UI as you can easily import these certificates in Postman UI.

But how to pass or send these files while trying to run these tests in Newman.

how to pass or send these files while trying to run these tests in Newman.

Based on your requirement, you need to pass multiple certificates when using Newman.

You can add the argument: --ssl-client-cert-list cer.json.

Here are the steps:

Step1: add the certificates in the json file.

For example:

[
    {
        "name": "domain1",
        "matches": ["https://test.domain1.com/*", "https://www.domain1/*"],
        "key": {"src": "./client.domain1.key"},
        "cert": {"src": "./client.domain1.crt"},
        "passphrase": "changeme"
    },
    {
        "name": "domain2",
        "matches": ["https://domain2.com/*"],
        "key": {"src": "./client.domain2.key"},
        "cert": {"src": "./client.domain2.crt"},
        "passphrase": "changeme"
    }
]

Step2: you can use the certificate json file in the newman commnad:

newman run "xxx" --ssl-client-cert-list "cer.json"
