Check Blocks

Check blocks evaluate conditions and branch the flow based on the result. They are essential for creating dynamic, intelligent contact flows.

Blocks in this Category

• CheckContactAttribute - Branch based on contact attribute values
• CheckHoursOfOperation - Branch based on business hours
• CheckStaffing - Branch based on agent availability
• CheckQueueStatus - Branch based on queue metrics
• GetQueueMetrics - Retrieve real-time queue statistics

Overview

Check blocks allow you to create conditional logic in your flows:

• Route by customer data - VIP customers, account status, language preference
• Handle business hours - Open vs. closed routing
• Check agent availability - Route based on staffing levels
• Monitor queue health - Handle high queue volumes

Common Patterns

Attribute-Based Routing

Flow.Create("VIP Routing")
    .InvokeLambda("GetCustomerInfo")
        .OnSuccess(s => s.SetContactAttributes(a => a["CustomerTier"] = Attributes.External("Tier")))
        .OnError(e => e.TransferToQueue("General"))
    .CheckContactAttribute(check =>
    {
        check.Attribute(Attributes.Contact("CustomerTier"))
            .Equals("VIP", vip => vip.TransferToQueue("VIPSupport"))
            .Equals("Premium", premium => premium.TransferToQueue("PremiumSupport"))
            .Otherwise(standard => standard.TransferToQueue("General"));
    })
    .Disconnect();

Hours-Based Routing

Flow.Create("Business Hours")
    .CheckHoursOfOperation("MainBusinessHours")
        .OnInHours(open => open.TransferToQueue("Sales"))
        .OnOutOfHours(closed => closed
            .PlayPrompt("We're closed. Please call during business hours.")
            .Disconnect())
        .OnError(error => error.TransferToQueue("Support"));

Staffing-Aware Routing

Flow.Create("Smart Queue")
    .CheckStaffingForQueue("SupportQueue", StaffingMetricType.Available)
        .OnTrue(available => available
            .PlayPrompt("An agent is available.")
            .TransferToQueue("SupportQueue"))
        .OnFalse(unavailable => unavailable
            .PlayPrompt("All agents are busy. You'll be placed in queue.")
            .TransferToQueue("SupportQueue"))
        .OnError(error => error.TransferToQueue("SupportQueue"));

Comparison Operators

CheckContactAttribute supports multiple comparison operators:

Method	Description	Example
.Equals(value)	Exact match	.Equals("VIP", ...)
.NotEquals(value)	Not equal	.NotEquals("Blocked", ...)
.Contains(value)	Contains substring	.Contains("Premium", ...)
.GreaterThan(value)	Numeric greater than	.GreaterThan("100", ...)
.LessThan(value)	Numeric less than	.LessThan("5", ...)
.Otherwise()	Default case	.Otherwise(...)

Error Handling

All check blocks support error handling:

.CheckHoursOfOperation("Hours")
    .OnInHours(...)
    .OnOutOfHours(...)
    .OnError(error => error
        .PlayPrompt("Unable to determine business hours. Transferring...")
        .TransferToQueue("Fallback"))
