@codenirvana Is there anything stopping this?

For the library API, we can directly support https://github.com/salesforce/tough-cookie CookieJar or through postman-request if the option of changing the base library is required sometime in the future.

For the CLI a json file can be used, tough-cookie has fromJSON/toJSON methods (https://github.com/salesforce/tough-cookie#cookiejarfromjsonstring).

If this looks okay then I can open a PR for the same.

@rohit-gohri Yes, the underlying postman-runtime library accepts a tough-cookie jar instance.
Refer: https://github.com/postmanlabs/newman/blob/develop/lib/run/index.js#L176

Please feel free to raise PR for this feature request. 🙂

@codenirvana Could you take a look at the PR? It would be really great if it got merged before the next release.

@codenirvana Sorry for pinging again, but this would be really helpful for my use-case. If you could have a look, it'd be great

[codenirvana]

Hey @rohit-gohri, sorry for getting back to you so late. I will definitely review this PR today.
