About this blueprint
Getting Started Inputs Software Engineering API Notifications
This flow is a simple example of a business process automation use case for vacation approval.
The user first submits a vacation request using a form automatically created in the Kestra UI thanks to inputs. The flow then sends a Slack message to request approval for a vacation, waits for the approval, and then processes the request. The approval is as simple as clicking on the Resume button in the Kestra UI.
The flow has three tasks: 1. The first task sends a Slack message to request approval for a vacation. 2. The second task pauses the execution to wait for the approval. 3. Once the execution is resumed, the third task processes the vacation request.
