How this Helps
On-demand workflows are useful for running tasks that need to be executed immediately or at the user’s discretion. They provide flexibility and control over when specific workflows are triggered, making them ideal for scenarios where timing is critical or user input is required.
| Interface | Description |
|---|---|
| Manual Trigger | Users with access to the Blink platform can also trigger workflows manually. |
| Blink Portal | Allows authorized users to trigger workflows through a dedicated UI. |
| Slack & Microsoft Teams | Enables workflow execution directly from messaging platforms. |
| Subflows | Workflows that can be used when triggered by a parent workflow, typically useful when the subflow is an action that is needed by more than one parent workflow. |
The file input parameter is not supported in triggered subflows.
