### Where this table plugs into the API

The values in this table are API values: you send one of them, exactly as it appears here, in the matching field of the document. Every field in the [REST API documentation](https://wrapp.ai/api/documentation) has a "values" button that opens the relevant table.

| Code | Description |
| --- | --- |
| 1 | Pieces |
| 2 | Kg |
| 3 | Litres |
| 4 | Metres |
| 5 | Square metres |
| 6 | Cubic metres |

## Frequently asked questions

### Are these official AADE codes?

Yes. The codes and descriptions follow the official AADE myDATA REST API documentation. The table shows the values the Wrapp API accepts.

### What happens if I send a code that is not in the table?

Depending on the field, the document is either rejected or transmitted with the wrong classification. Always use a value from the table.

### How often do they change?

They change when the legislation or the myDATA version changes. We update these tables along with the API, so this page reflects the current state.
