:::note{title="Interchange envelope of the process data"}

`Message` is the wrapper around a list of `processes` — the object carries nothing more.

The Prüfi and event specifications of this format version start at the *content* (`stammdaten`, `transaktionsdaten`, `zusatzdaten`) and do not reference any field of the envelope via `$ref`. The 0 uses in the summary line above therefore measure the `$ref` graph of these schemas and say nothing about whether the envelope is sent.

**Measured on 05.09.2026:** `updateProcessData` and `createProcessData` send `{stammdaten, transaktionsdaten, zusatzdaten}` — **without** this interchange envelope. The `businessKey` is located *in* `zusatzdaten`, not on the body. Established from the construction rule of the sender in the connector flow; the counter-check is the same flow, which does build an interchange envelope for the message to the process engine. **Not measured:** a captured real call, and the MaloIdent branch (03002/03003), which runs independently.

The interface specification shows the same body. The one outlier with a field `data` at the root is exactly **1 of 112** members of the `updateProcessData` schema of role LF and not a second body form.

The keys `businessKey`, `prozessId` and `targetBusinessKey` are described in context under [Keys](/en/schnittstellen/schluessel).
