Wait Step
The Wait step pauses a workflow until an external signal resumes the process and specific conditions are met. In RiskOS™, Wait steps are primarily designed to be resumed via an API PATCH call, though limited resume actions may also be triggered from Case Management.
Use cases
- Pending data: Pause until an external service provides required values (e.g., internal API, verification result).
- Custom backend triggers: Resume workflows when your system calls the API after downstream processing.
Configure a Wait step
- Select the Wait step in the workflow canvas to open the side panel.
- Configure the Wait queue settings. Entities that do not meet the resume conditions will remain paused in this queue until resumed:
- Status → The case status applied while waiting.
- Sub-status → The sub-status applied for additional categorization.
- Queue → The queue where paused cases are placed.
- Define the resume condition:
- Example: Resume if
document_idis not empty. - This ensures the workflow only continues when the API call provides the expected data.
- Example: Resume if
- Specify the output field:
- Each Wait step creates a Boolean output (
true/false). - This output can be checked in subsequent steps to confirm whether the Wait condition was met.
- Each Wait step creates a Boolean output (
- (Optional) Customize the Wait step’s label in the side panel for clarity.
Resume behavior
- API-first design: A workflow paused at a Wait step must be resumed through an API PATCH call.
- The call must reference the evaluation ID of the workflow instance to be resumed and include the required data.
- See the API reference for details on request format and payload fields.
- Case Management: In some scenarios, workflows can also be resumed from the Case Management interface, but no new data can be added this way.
- Resume conditions: If the resume condition evaluates to False (e.g., a null field), the workflow remains paused until the correct data is received.
Best practices
- Use sparingly: Avoid adding unnecessary Wait steps to reduce workflow complexity.
- Design meaningful resume conditions: Always tie the condition to a concrete event, such as “field is not null” or “value equals true.”
- Monitor paused workflows: Ensure you have monitoring and alerts to track workflows waiting for external triggers.
- Multiple Wait steps: Workflows may include more than one Wait step, but each must have a clearly defined resume trigger.
- Fallback strategies: Define what should happen if the external trigger never arrives (e.g., timeout logic handled in your system).
- Webhooks: If a workflow reaches a Wait step after being resumed (e.g., two consecutive Wait steps, or a Wait step followed by a DocV step), the system will send a webhook notifying downstream systems that the workflow resumed but is again paused.
- Build logic to handle these scenarios properly.
Notes
- Wait steps are meant for asynchronous flows that need specific data input.
- The resume condition is essential — without it, workflows may remain indefinitely paused.
- The system currently does not allow you to configure a timeout that automatically resumes a workflow.
- It is the customer’s responsibility to resume the workflow after a specific time.
- If no action is taken, the workflow will remain paused indefinitely.
Note:
The Wait step is available behind a feature flag. If you cannot see the Wait step in your Workflow Builder, please contact [email protected] to have it enabled.
