Configure Genesys Cloud Outbound Campaign IVR Menu Bouncer with Go

Configure Genesys Cloud Outbound Campaign IVR Menu Bouncer with Go

What You Will Build

This tutorial demonstrates how to programmatically configure an Outbound Campaign to bypass IVR menus using the Genesys Cloud Menu Bouncer feature. The code uses the official Genesys Cloud Go SDK to construct validation pipelines, apply atomic configuration updates, synchronize events via webhooks, and track execution metrics for campaign governance.

Prerequisites

  • OAuth 2.0 Client Credentials flow configured in Genesys Cloud
  • Required scopes: outbound:campaign:write, outbound:campaign:read, webhook:write, webhook:read
  • Go 1.21 or higher
  • SDK: github.com/MyPureCloud/platform-client-v4-go/v4
  • External dependencies: github.com/google/uuid, github.com/sirupsen/logrus, time, sync, math, net/http, encoding/json

Authentication Setup

The Genesys Cloud Go SDK handles OAuth token retrieval, caching, and automatic refresh when provided with valid client credentials. You must configure the base URL and authentication parameters before initializing any API client.

package main

import (
	"context"
	"fmt"
	"net/http"

	"github.com/MyPureCloud/platform-client-v4-go/v4/configuration"
	"github.com/MyPureCloud/platform-client-v4-go/v4/platformsv2/outbound"
	"github.com/MyPureCloud/platform-client-v4-go/v4/platformsv2/webhook"
)

func initializeGenesysClient(clientID, clientSecret, environment string) (*outbound.API, *webhook.API, error) {
	// Map environment string to base URL
	var baseURL string
	switch environment {
	case "us":
		baseURL = "https://api.mypurecloud.com"
	case "eu":
		baseURL = "https://api.eu.mypurecloud.com"
	case "au":
		baseURL = "https://api.au.mypurecloud.com"
	default:
		return nil, nil, fmt.Errorf("unsupported environment: %s", environment)
	}

	cfg := configuration.NewConfiguration()
	cfg.SetOAuthClientID(clientID)
	cfg.SetOAuthClientSecret(clientSecret)
	cfg.SetOAuthBaseURL(fmt.Sprintf("%s/oauth/token", baseURL))
	cfg.SetBaseURL(baseURL)
	
	// Configure HTTP client with timeout and retry transport
	cfg.SetHTTPClient(&http.Client{
		Timeout: 30 * time.Second,
	})

	outboundAPI := outbound.NewAPI(cfg)
	webhookAPI := webhook.NewAPI(cfg)

	return outboundAPI, webhookAPI, nil
}

Implementation

Step 1: Construct and Validate Menu Bouncer Payload

The Menu Bouncer configuration requires precise DTMF sequences, timeout calculations, and carrier validation. This function builds the payload, enforces the 32-digit DTMF limit, calculates dynamic timeouts, and verifies carrier restrictions.

import (
	"fmt"
	"regexp"
	"strings"
	"time"

	"github.com/MyPureCloud/platform-client-v4-go/v4/platformsv2/outbound"
)

type MenuBouncerParams struct {
	MenuRef             string
	DigitMatrix         []string
	SkipDirective       bool
	BaseTimeoutMs       int
	InterDigitTimeoutMs int
	AllowedCarriers     []string
	CarrierRestrictions []string
}

func constructMenuBouncerConfig(params MenuBouncerParams) (*outbound.MenuBouncerConfig, error) {
	// Validate menu reference format
	if !regexp.MustCompile(`^[a-zA-Z0-9_-]+$`).MatchString(params.MenuRef) {
		return nil, fmt.Errorf("invalid menu-ref format: must contain alphanumeric characters, hyphens, and underscores")
	}

	// Flatten digit matrix and enforce maximum DTMF length limit (32 digits)
	var flattenedDigits string
	for _, sequence := range params.DigitMatrix {
		if !regexp.MustCompile(`^[0-9A-D#*]+$`).MatchString(sequence) {
			return nil, fmt.Errorf("invalid digit matrix sequence: %s", sequence)
		}
		flattenedDigits += sequence
	}
	if len(flattenedDigits) > 32 {
		return nil, fmt.Errorf("dtmf length limit exceeded: %d digits (maximum 32)", len(flattenedDigits))
	}

	// Calculate timeout evaluation logic
	calculatedTimeout := params.BaseTimeoutMs + (len(flattenedDigits) * params.InterDigitTimeoutMs)
	if calculatedTimeout < 500 {
		calculatedTimeout = 500
	}
	if calculatedTimeout > 15000 {
		calculatedTimeout = 15000
	}

	// Carrier restriction verification pipeline
	allowedSet := make(map[string]bool)
	for _, c := range params.AllowedCarriers {
		allowedSet[strings.ToUpper(c)] = true
	}
	for _, r := range params.CarrierRestrictions {
		if !allowedSet[strings.ToUpper(r)] {
			return nil, fmt.Errorf("carrier restriction %s is not in the allowed carriers list", r)
		}
	}

	return &outbound.MenuBouncerConfig{
		Enabled:              true,
		MenuRef:              params.MenuRef,
		DigitMatrix:          params.DigitMatrix,
		Skip:                 params.SkipDirective,
		Timeout:              calculatedTimeout,
		DtmfLength:           len(flattenedDigits),
		CarrierRestrictions:  params.CarrierRestrictions,
		SkipInvalidSequences: true,
		AutoConnectOnTimeout: true,
	}, nil
}

Step 2: Atomic HTTP PUT Operation with Retry and Format Verification

Campaign updates require atomic execution. This function handles the HTTP PUT cycle, implements exponential backoff for 429 rate limits, and verifies the response schema matches the requested configuration.

import (
	"fmt"
	"math"
	"net/http"
	"time"
)

func updateCampaignWithRetry(ctx context.Context, api *outbound.API, campaignID string, menuConfig *outbound.MenuBouncerConfig) (*outbound.Campaign, error) {
	maxRetries := 5
	baseDelay := time.Second

	for attempt := 0; attempt <= maxRetries; attempt++ {
		request := outbound.UpdateCampaignRequest{
			MenuBouncerConfig: menuConfig,
		}

		// HTTP PUT /api/v2/outbound/campaigns/{id}
		result, httpResponse, err := api.UpdateCampaignWithHttpInfo(ctx, campaignID, request)
		
		if err != nil {
			if httpResponse != nil && httpResponse.StatusCode == http.StatusTooManyRequests {
				if attempt == maxRetries {
					return nil, fmt.Errorf("exceeded maximum retries for 429 rate limit")
				}
				delay := time.Duration(math.Pow(2, float64(attempt))) * baseDelay
				time.Sleep(delay)
				continue
			}
			if httpResponse != nil && httpResponse.StatusCode == http.StatusUnauthorized {
				return nil, fmt.Errorf("401 unauthorized: verify OAuth token and scopes")
			}
			if httpResponse != nil && httpResponse.StatusCode == http.StatusForbidden {
				return nil, fmt.Errorf("403 forbidden: missing outbound:campaign:write scope")
			}
			return nil, fmt.Errorf("unexpected API error: %w", err)
		}

		// Format verification
		if result.MenuBouncerConfig == nil {
			return nil, fmt.Errorf("format verification failed: menuBouncerConfig is missing in response")
		}
		if result.MenuBouncerConfig.Enabled != true {
			return nil, fmt.Errorf("format verification failed: menu bouncer did not enable")
		}

		return result, nil
	}

	return nil, fmt.Errorf("campaign update failed after retries")
}

Step 3: Webhook Synchronization and Latency Tracking

Synchronizing bypass events requires creating a webhook listener for the outbound_campaign_menu_bounced event. This step registers the endpoint, calculates latency, and tracks success rates for bypass efficiency monitoring.

import (
	"encoding/json"
	"fmt"
	"net/http"
	"sync"
	"time"
)

type BypassMetrics struct {
	mu           sync.Mutex
	TotalCalls   int
	Successful   int
	Failed       int
	TotalLatency time.Duration
}

func (m *BypassMetrics) Record(success bool, latency time.Duration) {
	m.mu.Lock()
	defer m.mu.Unlock()
	m.TotalCalls++
	m.TotalLatency += latency
	if success {
		m.Successful++
	} else {
		m.Failed++
	}
}

func (m *BypassMetrics) GetSuccessRate() float64 {
	m.mu.Lock()
	defer m.mu.Unlock()
	if m.TotalCalls == 0 {
		return 0.0
	}
	return float64(m.Successful) / float64(m.TotalCalls)
}

func registerMenuBouncedWebhook(ctx context.Context, api *webhook.API, targetURL string) (string, error) {
	webhookPayload := webhook.Webhook{
		Name:        "GenesysMenuBouncerSync",
		Description: "Synchronizes IVR menu bypass events with external telephony log",
		Uri:         targetURL,
		Method:      "POST",
		ContentType: "application/json",
		Events:      []string{"outbound_campaign_menu_bounced"},
		Headers: map[string]string{
			"X-Genesys-Event-Source": "outbound-campaign",
			"Content-Type":           "application/json",
		},
	}

	result, httpResponse, err := api.PostWebhooks(ctx, webhookPayload)
	if err != nil {
		if httpResponse != nil && httpResponse.StatusCode == http.StatusConflict {
			return "", fmt.Errorf("webhook already exists")
		}
		return "", fmt.Errorf("webhook registration failed: %w", err)
	}

	return *result.Id, nil
}

Step 4: Skip Validation Logic and Audit Generation

This pipeline validates incoming sequences against carrier restrictions, prevents call termination during scaling events, and generates structured audit logs for campaign governance.

import (
	"fmt"
	"time"
)

type AuditEntry struct {
	Timestamp   time.Time `json:"timestamp"`
	CampaignID  string    `json:"campaign_id"`
	MenuRef     string    `json:"menu_ref"`
	DTMFSequence string   `json:"dtmf_sequence"`
	SkipValid   bool      `json:"skip_valid"`
	CarrierOK   bool      `json:"carrier_ok"`
	LatencyMs   int64     `json:"latency_ms"`
}

func validateSkipSequence(sequence string, carrier string, allowedCarriers map[string]bool) (bool, bool) {
	// Invalid sequence checking
	if len(sequence) == 0 || sequence == "0" {
		return false, false
	}

	// Carrier restriction verification pipeline
	carrierValid := allowedCarriers[carrier]

	return true, carrierValid
}

func generateAuditLog(campaignID, menuRef, sequence, carrier string, latency time.Duration, allowedCarriers map[string]bool) AuditEntry {
	skipValid, carrierOK := validateSkipSequence(sequence, carrier, allowedCarriers)
	
	return AuditEntry{
		Timestamp:    time.Now().UTC(),
		CampaignID:   campaignID,
		MenuRef:      menuRef,
		DTMFSequence: sequence,
		SkipValid:    skipValid,
		CarrierOK:    carrierOK,
		LatencyMs:    latency.Milliseconds(),
	}
}

func logAuditEntry(entry AuditEntry) {
	payload, _ := json.Marshal(entry)
	fmt.Printf("[AUDIT] %s\n", string(payload))
}

Step 5: Menu Bouncer Controller Orchestration

The controller exposes a unified interface for automated Genesys Cloud management. It chains validation, configuration, webhook sync, and metric tracking into a single execution path.

type MenuBouncerController struct {
	OutboundAPI  *outbound.API
	WebhookAPI   *webhook.API
	Metrics      *BypassMetrics
	AllowedCarriers map[string]bool
}

func NewMenuBouncerController(outboundAPI *outbound.API, webhookAPI *webhook.API, allowedCarriers []string) *MenuBouncerController {
	allowedSet := make(map[string]bool)
	for _, c := range allowedCarriers {
		allowedSet[c] = true
	}
	return &MenuBouncerController{
		OutboundAPI:     outboundAPI,
		WebhookAPI:      webhookAPI,
		Metrics:         &BypassMetrics{},
		AllowedCarriers: allowedSet,
	}
}

func (c *MenuBouncerController) ConfigureCampaign(ctx context.Context, campaignID string, params MenuBouncerParams, webhookURL string) error {
	startTime := time.Now()

	// Step 1: Construct and validate payload
	menuConfig, err := constructMenuBouncerConfig(params)
	if err != nil {
		return fmt.Errorf("payload validation failed: %w", err)
	}

	// Step 2: Atomic PUT operation
	updatedCampaign, err := updateCampaignWithRetry(ctx, c.OutboundAPI, campaignID, menuConfig)
	if err != nil {
		return fmt.Errorf("campaign update failed: %w", err)
	}

	// Step 3: Webhook synchronization
	_, err = registerMenuBouncedWebhook(ctx, c.WebhookAPI, webhookURL)
	if err != nil {
		return fmt.Errorf("webhook sync failed: %w", err)
	}

	// Step 4: Audit and latency tracking
	latency := time.Since(startTime)
	c.Metrics.Record(true, latency)

	auditEntry := generateAuditLog(
		campaignID,
		params.MenuRef,
		strings.Join(params.DigitMatrix, ""),
		params.CarrierRestrictions[0],
		latency,
		c.AllowedCarriers,
	)
	logAuditEntry(auditEntry)

	fmt.Printf("Campaign %s configured successfully. Latency: %v. Success Rate: %.2f%%\n", 
		updatedCampaign.Id, latency, c.Metrics.GetSuccessRate()*100)

	return nil
}

Complete Working Example

The following script combines all components into a runnable module. Replace the placeholder credentials and campaign identifiers before execution.

package main

import (
	"context"
	"fmt"
	"time"

	"github.com/MyPureCloud/platform-client-v4-go/v4/configuration"
	"github.com/MyPureCloud/platform-client-v4-go/v4/platformsv2/outbound"
	"github.com/MyPureCloud/platform-client-v4-go/v4/platformsv2/webhook"
)

// Paste all functions from Steps 1-5 here in a single file structure

func main() {
	ctx := context.Background()

	// Initialize client
	outboundAPI, webhookAPI, err := initializeGenesysClient("YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET", "us")
	if err != nil {
		fmt.Printf("Initialization failed: %v\n", err)
		return
	}

	controller := NewMenuBouncerController(
		outboundAPI, 
		webhookAPI, 
		[]string{"TWILIO", "PHONE_COM", "EXOS"},
	)

	params := MenuBouncerParams{
		MenuRef:             "sales-ivr-bypass",
		DigitMatrix:         []string{"1", "2", "#"},
		SkipDirective:       true,
		BaseTimeoutMs:       1000,
		InterDigitTimeoutMs: 200,
		AllowedCarriers:     []string{"TWILIO", "PHONE_COM", "EXOS"},
		CarrierRestrictions: []string{"TWILIO"},
	}

	err = controller.ConfigureCampaign(ctx, "a1b2c3d4-e5f6-7890-abcd-ef1234567890", params, "https://your-telephony-log.example.com/gen-webhook")
	if err != nil {
		fmt.Printf("Execution failed: %v\n", err)
	}
}

Common Errors & Debugging

Error: 401 Unauthorized

  • Cause: The OAuth token has expired or the client credentials are incorrect.
  • Fix: Verify the clientID and clientSecret match the Genesys Cloud integration. Ensure the oauth/token endpoint matches your environment. The SDK automatically refreshes tokens, but initial authentication requires valid secrets.
  • Code Fix: Check the configuration.NewConfiguration() block and confirm SetOAuthClientID and SetOAuthClientSecret contain exact values.

Error: 403 Forbidden

  • Cause: The OAuth client lacks the outbound:campaign:write scope.
  • Fix: Navigate to the Genesys Cloud admin console, open the integration settings, and add the required scopes. Restart the application to force a new token fetch.
  • Code Fix: No code change required. The error message explicitly states the missing scope.

Error: 429 Too Many Requests

  • Cause: Campaign update rate limits triggered by rapid scaling or concurrent deployments.
  • Fix: The updateCampaignWithRetry function implements exponential backoff. If failures persist, reduce the deployment frequency or implement a queue-based scheduler.
  • Code Fix: Increase maxRetries in the retry loop or adjust baseDelay to time.Duration(2 * time.Second).

Error: DTMF Length Limit Exceeded

  • Cause: The flattened digit matrix exceeds 32 characters. Genesys Cloud enforces this limit to prevent telephony stack timeouts.
  • Fix: Trim the DigitMatrix array or consolidate sequences. Validate input before passing to constructMenuBouncerConfig.
  • Code Fix: The validation function returns an explicit error. Adjust the payload to use fewer DTMF digits or leverage the SkipDirective flag to reduce required sequences.
