## get\_field()

After the checklist completes and `agent.on_task_complete` fires, use `call.get_field()` to retrieve collected values by their key. This is where you write results to your CRM, database, or EHR.

### Signature

```python
def get_field(field_key: str) -> str | int | dict | None
```

### Example

```python
@agent.on_task_complete("schedule_appointment")
def on_appointment_scheduled(call: guava.Call):
    appointment_time = call.get_field("appointment_time")
    patient_name = call.get_field("patient_name")
    # Write to your CRM / EHR
    save_appointment(patient_name, appointment_time)
    call.hangup()
```

### Return types by field type

The type of the value returned by `get_field()` depends on the field's `field_type`:

| `field_type`       | Returned value                                                                 |
|--------------------|-------------------------------------------------------------------------------|
| `text`             | `str`                                                                         |
| `date`             | `dict` with keys `year`, `month`, `day` (all `int`)                         |
| `integer`          | `int`                                                                         |
| `multiple_choice`  | `str` (guaranteed to be one of the values in `choices` or returned by `choice_generator`) |
| `calendar_slot`    | ISO-8601 datetime string (e.g. "2022-12-25T16:30")                         |

Tip: You can call `get_field()` at any point after the field has been collected — not just in `on_task_complete`. Use it in mid-call callbacks to personalize subsequent steps.
