Hi All, i am trying to get the NetSuite salesorder and itemfulfillment details using SOAP UI tool do i need to pass unique nonce, timestamp, signature for every request that i made....?

Yes, you need to generate a unique

nonce

for each request.

signature...?

Yes. The signature is a hash of your account ID, consumer key, token, nonce, and timestamp. So if the nonce and timestamp change, then the signature must be recalculated. https://system.na0.netsuite.com/app/help/helpcenter.nl?fid=section_4395630653.html

Thank You for your time
