Hi,
when using Zeebe gRPC API to evaluate DMN, there is no field for DecisionInstanceKey, is there a method to refer to evaluated decision in Operate when assessed via API?
thank you
Correct. The response of the Zeebe gRPC call doesn’t contain a reference to Operate’s Id of the decision instance (ref ).
However, the response contains the output of the evaluation, like the output value.
Why do you want to query the Operate API?

Hi @Philipp_Ossler ,
Thank you for your reply, I need to get decision instances key based on the response from Zeebe. For example, when I receive the response evaluation from Zeebe using a gRPC call, we need the decision instances key to view the history in Operate

**Is your feature request related to a problem? Please describe.**
when using… gRPC call API (https://docs.camunda.io/docs/apis-tools/zeebe-api/gateway-service/#evaluatedecision-rpc) to evaluate decision, the response does not contains `Decision Instance Key` so we can't see history in Operate decision history.
**Describe the solution you'd like**
the response from this gRPC API https://docs.camunda.io/docs/apis-tools/zeebe-api/gateway-service/#evaluatedecision-rpc contain `Decision Instance Key` that will match Decision Instance Key from Operate decision.
**Additional context**
- example response from gRPC evaluation
