External Task Providers

Kanboard can be used to manage tasks stored in another system. For example, an external system can be a bug tracker or any kind of ticketing software. In this way, you can use Kanboard to manage external tasks in the same way as native tasks.

Workflow

Creation:

The end-user select an alternative task provider during the task creation
The external task provider expose a form to the user to be able to fetch the external task
The external task is retrieved from the other system
A customized form is shown to the user

Visualization:

When the task detail page is opened, Kanboard will load asynchronously the remote task. This information might be cached by the plugin to improve the loading time.

Modification:

Optionally, the plugin can offer a custom form to save extra information to the external system.

External task providers must implements at least two interfaces:

Kanboard\Core\ExternalTask\ExternalTaskProviderInterface
Kanboard\Core\ExternalTask\ExternalTaskInterface
