I have a client and server setup. Client initiates tcp handshake with server, then sends request with some xml data attached to the tcp packet. The server responds also with xml data attached to the tcp packet. Would it be possible to test this in Postman?

If its an HTTP request then yes although xml requests and responses are a bit harder to work with over JSON\rest.

If you are new to Postman, then I would suggest a visit to the Learning Centre.

[Overview | Postman Learning Center](https://learning.postman.com/docs/introduction/overview/)

Including the Postman Training links under “Other Resources”.

I would recommend the “Galaxy APIs 101” course first as it gets you used to the application features.

Then the “Galaxy Testing and Automation” course which teaches you how to assert the responses. It includes defining and using variables from responses.

It is not http base, just using raw tcp to transmit xml data between two nodes.

Thanks

Then probably not.

Postman requires the http method (post\get) to be included in the request alongside the URL.
