### 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 | Stamp duty % cases | Stamp duty |
| --- | --- | --- |
| 1 | Rate 1,2 % | 1,20% |
| 2 | Rate 2,4 % | 2,40% |
| 3 | Rate 3,6 % | 3,60% |
| 4 | Charges of other Taxes | amount |

## 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.
