Looking for end-to-end guidance on calling FlowX from your own app? See Consuming FlowX from external apps.
Start a new process instance and seed its data from a previously executed process instance. The new process picks up the data values that were on the source instance at the moment of the call. Common use cases:
  • Replaying a failed workflow with the same input
  • Cloning an existing case for a similar customer
  • Resuming downstream processing after an interruption

​
Path parameters

​
workspaceId
string
required
The ID of the workspace that owns the application.
​
appId
string
required
The ID of the application.
​
processName
string
required
The name of the process definition to start.
​
processInstanceId
string
required
The UUID of the source process instance. Its data is copied into the new instance at start time.

​
Request headers

​
Authorization
string
required
Bearer token. Format: Bearer <token>.
​
Content-Type
string
required
Must be application/json.

​
Request body

A JSON object with values to merge on top of the copied data. Pass {} to start with the source instance’s data unchanged. 
{
  "retryReason": "manual-rerun",
  "operatorId": "u-9023"
}

​
Response

Same shape as Start process by workspace, app, and process name — the new instance’s uuid, state, and metadata.
