An OmniStudio Developer is configuring an Integration Procedure Action in an OmniScript.

Invoke Mode Non-Blocking is the correct choice because the OmniScript still needs the Integration Procedure response, but the user interface should not be blocked while waiting. Salesforce describes Non-Blocking as running asynchronously while applying the response to the UI. Fire and Forget is different: it is used when the caller does not need a response returned to the OmniScript. Use Future is also asynchronous, but it is best when completion timing is not critical and no response is required. Toast Completion only controls a user notification style; it does not determine whether the OmniScript waits for the Integration Procedure response. Since the response must still come back as JSON while the user proceeds, Non-Blocking is the correct feature.
