POST Workflow Instances Instance ID Signals

The POST /WorkflowClosed A workflow is a series of steps necessary to complete a process. In the context of Keyfactor Command, it refers to the workflow builder, which allows you automate event-driven tasks when a certificate is requested or revoked./Instances/{instanceId}/Signals method is used to input signals to the workflow instance with the specified GUID. This endpointClosed An endpoint is a URL that enables the API to gain access to resources on a server. returns 204 with no content upon success.

Note:  If a workflow instance is initiated for a workflow definition that has more than one step requiring input (signals), a user can only provide that input (e.g. approve or deny a require approval request) at the step in the workflow instance where the workflow instance was suspended pending input. The user cannot jump ahead and provide input for future steps in the workflow that have not yet occurred.
Note:  A locking conflict may occur if two (or more) users attempt to provide input to a workflow instance (e.g. approve a request) at exactly the same time. If this happens, input from only one of the users will be reflected in the Management Portal, and the workflow instance will not be moved along to the next step if it should have been with input from the two users. The other input is still accepted, however, and there is a scheduled task that runs daily and attempts to continue all suspended workflows that may be eligible to continue but have not done so due to locking conflicts.
Tip:  The following permissions (see Security Overview) are required to use this feature:

The user executing the request must hold at least one security role ID configured in the workflow definition step for which signal data is being input.

Use the GET /Workflow/Instances method (see GET Workflow Instances) to retrieve a list of all the workflow instances to determine the GUID.

signal Body
