Publish and unpublish workflows
In the Workflows view of the dashboard you can see which workflows are published by looking at the color of their dot (green means published).
Only published workflows that are linked to an API key can be used via the NL Flow API, while all published workflows can be tested interactively.
API keys are an authorization mechanism: each request submitted to the API must contain—inside a specific header—the API key that has been linked to the workflow.
There can be a many-to-many relationship between published workflows and API keys: the same API key can be linked to more workflows and the same workflow can be linked to more keys. To manage API keys use the Runtime view of the dashboard.
