To call expression sets with context definitions from a flow, see [How to Use Business Rules Engine to Preapprove Health Cloud Care Requests](https://help.salesforce.com/s/articleView?id=ind.bre_hc_prior_auth.htm&release=264.0.0&type=5 "Configure and test the Business Rules Engine features by using a Health Cloud Prior Authorization of Care Requests scenario.").

To call an expression set with a Decision Explainer component from a flow, see [Example: Create a Flow to Run the Expression Set and Update the Record](https://help.salesforce.com/s/articleView?id=ind.invoke_es_from_flow.htm&release=264.0.0&type=5 "Create an input form to capture a contact’s step count and pass it to the expression set action. Configure the flow to update the contact record with the expression set’s output.").

    After a decision matrix is activated, invoke the decision matrix in a flow to provide outcomes and use the outcomes in the flow.
- **[Invoke a Decision Table in a Flow](https://help.salesforce.com/s/articleView?id=ind.task_invoke_a_decision_table_in_a_flow.htm&release=264.0.0&type=5)**

    After an expression set version that has decision explanations enabled is activated, call the expression set that the version belongs to from a flow. To capture action logs for the expression set runs, specify values for the autogenerated \_\_actionContextCode and \_\_specName parameters in the flow.
