## Frequently asked questions

### Where do I use these codes?

You send them in the matching fields of the Wrapp API when you issue a document. Every field in the API documentation has a "values" button that opens the relevant table.

### 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.
