# Wait for approval

Put a question to a person and stop until they answer. The turn keeps its place for as long as it takes, and the answer, or a decline, becomes the step’s value.

Wait step, Wait for approval:

- Step kind: `Wait`
- Operation: `Clarification`
- Question: `This refund is over $500. Approve it?`

## Inputs

- `Operation` (string, required): A declared wait the question goes through, usually Clarification. Its registration decides what an answer may be.
- `Question` (string, required): The question put to the person, as written.

## Outputs

- `<answer>` (string | object): The answer, checked against the wait’s schema. Through Clarification it is the person’s text, or a decline:
  - `Declined` (true): Present when the person said no.
  - `Reason` (string): Why, where they said.

## Example

```yaml
Operations:
  - Wait: Clarification
    Locator: embedded://momor.ai/services/tools/clarification

Steps:
  - Wait: Approve
    Operation: Clarification
    Question: This refund is over $500. Approve it?
  - Branch: Decision
    Cases:
      - When: { Exists: { Field: Approve.Declined } }
        Then:
          - ModelCall: Declined
            Instructions: Say the refund was declined, and why.
            Output: Content
    Else:
      - ExecuteTool: Pay
        Operations: [IssueRefund]
```

A decline is an answer, not a failure: the step completes with it, and the workflow decides what follows. Here `Exists` holds only for a decline, because a text answer has no `Declined` field.

## Answering

The raised question appears on the run’s event stream as `wait.intervention.raised`, with its `waitId` and the question. Answer it with [`POST /workflow/runs/{runId}/waits/{waitId}`](/docs/workflows/api/answer-a-question/). The run’s owner answers: the signed-in person or the API key that started it.

> **Not in the step**
> The step names no approver and no time limit. Momor does not deliver the question to anyone; the system that started the run shows it to the right person and posts their answer. A question stays open until it is answered or the turn ends.
