Contributors list

Harvested is feature frozen and will not accept new feature additions. It will not support the V2 API.

For more information about the reasons for that decision, please read

Harvested: A Ruby Harvest API

This is a Ruby wrapper for the Harvest API.


gem install harvested


harvest = Harvest.client(subdomain: 'yoursubdomain', username: 'yourusername', password: 'yourpassword')
harvest.projects.all   # list out projects

client = => "Billable Company LTD.") client = harvest.clients.create(client) harvest.clients.find( # returns a Harvest::Client

You can also pass query options in as the last parameter on any object's

finder method, for example to find all the projects for client ID 12345:
harvest = Harvest.client(subdomain: 'yoursubdomain', username: 'yourusername', password: 'yourpassword')
harvest.projects.all(nil, :client => 12345)

Note: the first parameter is a User ID field that is optional, but needs to be specified as nil if not included.

You can pass in any hash of query attributes you wish as per the Harvest API page.

You can find more examples in

and in the documentation for Harvest::Base


For most operations you need to be an Admin on the Harvest account. You can do a few select things as a normal user or a project manager, but you will likely get errors.

Hardy Client

The team at Harvest built a great API, but there are always dangers in writing code that depends on an API. For example: HTTP Timeouts, Occasional Bad Gateways, and Rate Limiting issues need to be accounted for.


your code needs to handle all these situations. However you can also use
which will retry errors and wait for Rate Limit resets.
harvest = Harvest.hardy_client(subdomain: 'yoursubdomain', username: 'yourusername', password: 'yourpassword')
harvest.projects.all   # This will wait for the Rate Limit reset if you have gone over your limit
