# Forward

> Accept documents forwarded from another pipeline's AI classification.

<Note>This node is in **preview**. Its behavior may change in future releases.</Note>

The forward trigger starts a pipeline run with a document that another pipeline forwarded to it. Pair it with the [Classify action](/nodes/classify) in AI mode (or a [Forward output](/nodes/forward-output)) in another pipeline to split documents across specialized pipelines based on their content.

## Configuration

| Field               | Type            | Required | Description                                                                      |
| ------------------- | --------------- | -------- | -------------------------------------------------------------------------------- |
| **Classifications** | document picker | Yes      | Up to five reference documents used to train AI classification for this pipeline |

### Classifications

Ingestly compares incoming pages against the reference documents you select and only forwards pages that are a close enough match, based on the [Classify action](/nodes/classify) **Confidence Threshold**.

1. Upload at least one document to the pipeline so it appears in the picker
2. Open the forward trigger node and select up to five documents
3. Click **Generate**
4. Confirm to generate classification embeddings. Generation costs **0.2 credits per page**

After generation the picker shows the existing references. Remove a reference at any time to retrain. A pipeline with no classifications cannot be selected as a target from a Classify action in AI mode.

## Inputs and outputs

**Allowed inputs:** None. This is a trigger node.

**Output:** The forwarded document, passed to the next connected node.
