How to make an OAuth1.0 Signature with Dart language

edited Mar 3, 2023 7:39PM in Ask A Guru 4 comments

We have a custom program written in Dart that we need to connect with Netsuite using REST web services. However, we cannot get the signature to be valid. No matter what we try, we always get an

InvalidSignature detail in the Login Audit Trail.

Has anyone had success in generating a valid signature using Dart? Or can anyone refer us to official documentation on how and what needs to be present in making the signature? We are including the following parameters to generate the signature:

oauth_consumer_key

oauth_nonce

oauth_signature_method

oauth_timestamp

oauth_token

oauth_version


Is there anything that we are missing? Something specific or unique to NetSuite that we are omitting? We are really struggling to make this work.

Howdy, Stranger!
