test workflow

Harvest Forecast is a planification tool built by Harvest.

This PHP SDK is generated automatically with JanePHP using a Forecast OpenAPI specification. It means that:

  • the code in the generated dorectory is not hand-written but generated;
  • if the API changes and you need to fix an API call, please edit the OpenAPI specification file, then regenerate the SDK.


This library is built atop of PSR-7 and PSR-18. So you will need to install some implementations for those interfaces.

If no PSR-18 client or PSR-7 message factory is available yet in your project or you don't care which one to use, just install some default:

composer require symfony/http-client nyholm/psr7

You can now install the Forecast client:

composer require jolicode/forecast-php-api


First, you need to retrieve an access token. Please checkout Harvest's documentation about the OAuth2 Authorization Flow.

Then, use the factory that is provided to create the client:

// $client contains all the methods to interact with the API
$client = JoliCode\Forecast\ClientFactory::create(

$clients = $client->listClients()->getClients();
$assignments = $client->listAssignments([
  'start_date' => '2019-01-01',
  'end_date' => '2019-01-31',


In the above example, the $client variable is an instance of the Client class, which you can browse through to learn more about the API features.
