url(url)

url is used to get continued or paginated data from the API. Queries with long results return a reference to the next sete. Example -

next: 'https://api.robinhood.com/orders/?cursor=cD0yMD82LTA0LTAzKzkwJVNCNTclM0ExNC45MzYyKDYlMkIwoCUzqtAW' }

The url returned can be passed to the url method to continue getting the next set of results.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Contributing

Bug reports and pull requests are welcome on GitHub at https://github.com/rememberlenny/robinhood-ruby. This project is intended to be a safe, welcoming space for collaboration, and contributors are expected to adhere to the Contributor Covenant code of conduct.

Furthermore, I believe they are working on an amazing product, and hope that by publishing this NodeJS framework their users can benefit in even more ways from working with them.
