uninitialized constant OAuth (NameError) Did you mean? OAuth2

[varun43in]

Hi guys,

I'm currently at quickbooks-ruby 1.0.1 and everything is working perfectly,
But the moment I use 1.0.3 or higher, I get this error message when starting the rails server:

uninitialized constant OAuth (NameError) Did you mean? OAuth2

It's referring to this line (/config/initializers/quickbooks.rb):

$qb_oauth_consumer = OAuth::Consumer.new(QB_KEY, QB_SECRET, {
                       :site                 => "https://oauth.intuit.com",
                       :request_token_path   => "/oauth/v1/get_request_token",
                       :authorize_url        => "https://appcenter.intuit.com/Connect/Begin",
                       :access_token_path    => "/oauth/v1/get_access_token"
                   })

reverting back to quickbooks-ruby 1.0.1 makes everything run properly again.

Am I missing some 'require' statement somewhere or does the piece of code above need updating?

Thanks!

@varun43in That very old 1.0.1 version of the gem allowed either OAuth 1 or OAuth2 (https://github.com/ruckus/quickbooks-ruby/blob/1.0.1/quickbooks-ruby.gemspec). It looks like as of version 1.0.2, only OAuth 2 is supported (https://github.com/ruckus/quickbooks-ruby/blob/1.0.2/quickbooks-ruby.gemspec).

Intuit stopped supporting OAuth 1 on accounts a while back (https://blogs.intuit.com/blog/2018/12/20/oauth-1-0-deprecation-migrate-oauth-2-0-december-17-2019/). So, you'll presumably want to move to OAuth 2 (any newer development account is using that).

I'd start by looking at https://github.com/ruckus/quickbooks-ruby/tree/1.0.3#getting-started--initiating-authentication-flow-with-intuit (or later versions) - the start of the changes you'll want is moving from OAuth::Consumer to OAuth2::Client.
