# Trigger pipeline from a block

> You can trigger another pipeline from a block within a different pipeline.

## How to trigger a pipeline

There are 2 ways you can trigger a pipeline from code:

### Block template

Add a [data loader](/development/blocks/data_loaders/templates#trigger-pipeline)
or [data exporter](/development/blocks/data_exporters/templates#trigger-pipeline)
block template named `Orchestration → Trigger pipeline`.

### Custom code

Add a block and use the following code example within the block’s function:

```python theme={"system"}
from mage_ai.orchestration.triggers.api import trigger_pipeline


trigger_pipeline(
    'pipeline_uuid',
    variables={},
    check_status=False,
    error_on_failure=False,
    poll_interval=60,
    poll_timeout=None,
    schedule_name=None,  # Enter a unique name to create a new trigger each time
    verbose=True,
)
```

| `pipeline_uuid`    | The UUID of the pipeline to trigger.                                                                           |         | `example_pipeline` | ✅        |

| `verbose`          | Print status of triggered pipeline run.                                                                        | `True`  | `False` or `True`  |          |
