End the current flow without disconnecting the contact. Used in whisper flows and subflows.

Signature

IFlowBuilder EndFlowExecution(string? identifier = null)

Parameters

Parameter	Type	Required	Description
identifier	string?	No	Optional identifier for the action

When to Use

Scenario	Use EndFlowExecution
Agent whisper flow	✅ Yes
Customer whisper flow	✅ Yes
Subflow returning to parent	✅ Yes
Main contact flow ending	❌ No, use Disconnect
Queue transfer	❌ No, use Disconnect

Examples

Agent Whisper Flow

Flow.Create("VIPAgentWhisper")
    .SetType(FlowType.AgentWhisper)
    .SetDescription("Notifies agent of VIP customer")
    .PlayPrompt(message =>
    {
        message.SSML = @"<speak>
            <emphasis level='strong'>VIP Customer</emphasis>
            <break time='300ms'/>
            Account: <say-as interpret-as='digits'>" + Attributes.Contact("AccountId") + @"</say-as>
        </speak>";
    })
    .EndFlowExecution();  // Returns control, doesn't disconnect

Customer Whisper Flow

Flow.Create("CustomerWhisper")
    .SetType(FlowType.CustomerWhisper)
    .SetDescription("Plays to customer before agent connection")
    .PlayPrompt("Your call is now being connected to an agent.")
    .EndFlowExecution();

Subflow with Return

// Authentication subflow
Flow.Create("AuthenticationFlow")
    .SetType(FlowType.ContactFlow)
    .StoreCustomerInput("Enter your PIN.", input => input.MaxDigits = 4)
        .OnSuccess(s => s
            .InvokeLambda("ValidatePIN")
                .OnSuccess(valid => valid
                    .SetContactAttributes(attrs => attrs["Authenticated"] = "true")
                    .EndFlowExecution())  // Return to calling flow
                .OnError(invalid => invalid
                    .SetContactAttributes(attrs => attrs["Authenticated"] = "false")
                    .EndFlowExecution()))
        .OnError(e => e
            .SetContactAttributes(attrs => attrs["Authenticated"] = "false")
            .EndFlowExecution());

// Main flow calls authentication
Flow.Create("MainFlow")
    .TransferToFlow("AuthenticationFlow")
    // Execution continues here after EndFlowExecution
    .CheckContactAttribute(check =>
    {
        check.Attribute(Attributes.Contact("Authenticated"))
            .Equals("true", auth => auth.TransferToQueue("Authenticated"))
            .Otherwise(unauth => unauth.TransferToQueue("General"));
    })
    .Disconnect();

Hold Flow

Flow.Create("CustomerHold")
    .SetType(FlowType.CustomerHold)
    .PlayPrompt("Please continue to hold. Your call is important to us.")
    .Wait(30)
    .PlayPrompt("Thank you for your patience.")
    .EndFlowExecution();  // Loop back to hold music

Queue Flow

Flow.Create("CustomerQueue")
    .SetType(FlowType.CustomerQueue)
    .PlayPrompt("You are caller number 5 in the queue.")
    .PlayPrompt("Expected wait time is approximately 10 minutes.")
    .EndFlowExecution();  // Continue queue handling

Difference from Disconnect

Aspect	EndFlowExecution	Disconnect
Contact state	Active	Ended
Agent connection	Can proceed	Terminated
Use case	Whispers, subflows	End of interaction
Flow type	Any	Contact flows only

AWS Connect Block Type

This block generates the EndFlowExecution action type in the exported flow JSON.

Best Practices

1. Use in whisper flows - Required for proper whisper termination
2. Use in subflows - When returning to parent flow
3. Don't use for main flows - Use Disconnect instead
4. Set attributes before ending - Pass data back to parent
