Issues Generating a REST Web Services Signature

Anyone have any insight into creating the signature for a REST API SuiteQL signature?  I have one for authenticating and calling a RESTlet script, and it works just fine in my app, but when I try to call the REST API for a SuiteQL query, I keep getting signature errors.

Guessing I must be missing something obvious.  Changing the URLs to the SuiteQL ones keeps returning me error: “error=”token_rejected”, error_description=”Invalid login attempt.””…  But my TBA credentials work perfectly fine with a RESTlet URL instead…

I’m generating my signature using Crypto JS.

My personal recommendation would be to use OAuth 1.0a. Otherwise expect to share your code and hope someone can see the issue.

Do you have any documentation on generating the signature for the REST Web Service API?  I am using OAuth 1.0.  But, I can’t use Node.

Not sure what environment you are using, but OAuth 1.0a is universal enough to run in both browsers and node.

Yeah, I’m not running in a browser or Node.  The issue is not running OAuth, though.  I’m trying to figure out why the signature works fine when calling a RESTlet URL, but does not work when I try to call the REST web services suiteQL URL.

I can’t find anything in the docs about generating the signature for REST Web services, though… :/

Same signature generation for both. I’ve used bascially the same code for both RESTlet and the Suitetalk REST using OAuth 1.0a in node. You probably need to share your code for more help

Yeah, I’m using the same signature code.   The only difference I see is the URL.  I’ve tried adding the query string (same as for RESTlets) and not adding it, tot he signature generation.  Both ways I get the same Invalid Signature error.

Hi Charles,

While I don’t think I can provide an answer in Node I can provide an answer in Python as I too had a similar issue. Here’s a link to a sample code set I found in StackOverflow for Python referencing how to access the RESTlet API using Python. I tried using this sample code for REST Web Services and it did not work. Here are the pieces I had to update in order to successfully access REST Web Services API:

URL:  “” I’m sure you are using this but I figured it worth mentioning the slight differences in the URL just in case.

Nonce/Timestamp/Headers: I had to use Python library “oauthlib” in order to sign the request. This enabled me to mimic what was happening in Postman since all the official Netsuite docs reference using Postman but don’t mention anything about signing requests outside of Postman.


Once I implemented oauthlib I was able to successfully sign requests in a way that Netsuite REST Web Services wanted. I know this is rather generic but I hope this at least helps you down the right path.

you can try this library for making requests using nodejs,
