RE: Issues Generating a REST Web Services Signature
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.
