Configuring Genesys Cloud Outbound Campaign Dialer Settings via API with Go

What You Will Build

A production-grade Go service that constructs, validates, activates, and continuously optimizes Genesys Cloud outbound campaigns using the official SDK. The code handles progressive dialer configuration, regulatory compliance validation, asynchronous activation polling, dynamic dial rate adjustment based on real-time metrics, webhook synchronization for workforce management, disposition tracking, and audit log generation.

Prerequisites

• Genesys Cloud OAuth2 client credentials (Client ID and Client Secret)
• Required OAuth scopes: outbound:campaign:write, outbound:campaign:read, analytics:outbound:view, webhook:write, audit:read, oauth:clientid
• Go 1.21 or higher
• Genesys Cloud Go SDK: github.com/genesyscloud/genesyscloud-go-sdk
• External dependencies: github.com/go-resty/resty/v2 (for raw HTTP fallback), time, context, encoding/json

Authentication Setup

Genesys Cloud uses OAuth2 client credentials grant for server-to-server API access. The following function obtains an access token and implements basic token caching with automatic refresh logic.

package main

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

type OAuthTokenResponse struct {
	AccessToken string `json:"access_token"`
	ExpiresIn   int64  `json:"expires_in"`
}

var (
	tokenCache string
	tokenExpiry time.Time
	tokenMutex  sync.Mutex
)

func GetAccessToken(clientID, clientSecret, envURL string) (string, error) {
	tokenMutex.Lock()
	defer tokenMutex.Unlock()

	if tokenCache != "" && time.Now().Before(tokenExpiry.Add(-time.Minute)) {
		return tokenCache, nil
	}

	payload := fmt.Sprintf("client_id=%s&client_secret=%s&grant_type=client_credentials", clientID, clientSecret)
	req, err := http.NewRequest("POST", fmt.Sprintf("%s/oauth/token", envURL), nil)
	if err != nil {
		return "", fmt.Errorf("failed to create oauth request: %w", err)
	}
	req.SetBasicAuth(clientID, clientSecret)
	req.Header.Set("Content-Type", "application/x-www-form-urlencoded")

	client := &http.Client{Timeout: 10 * time.Second}
	resp, err := client.Do(req)
	if err != nil {
		return "", fmt.Errorf("oauth request failed: %w", err)
	}
	defer resp.Body.Close()

	if resp.StatusCode != http.StatusOK {
		return "", fmt.Errorf("oauth failed with status %d", resp.StatusCode)
	}

	var tokenResp OAuthTokenResponse
	if err := json.NewDecoder(resp.Body).Decode(&tokenResp); err != nil {
		return "", fmt.Errorf("failed to decode oauth response: %w", err)
	}

	tokenCache = tokenResp.AccessToken
	tokenExpiry = time.Now().Add(time.Duration(tokenResp.ExpiresIn) * time.Second)
	return tokenCache, nil
}

Required Scope: oauth:clientid

Implementation

Step 1: Construct and Validate Dialer Configuration Payloads

The progressive dialer configuration requires strict parameter validation to comply with TCPA, GDPR, and internal compliance policies. The following function builds the campaign payload and enforces regulatory constraints before submission.

import (
	"fmt"
	"github.com/genesyscloud/genesyscloud-go-sdk/genesyscloud"
)

func BuildAndValidateCampaignPayload(name, contactListID, wrapUpCodeID string) (*genesyscloud.Campaign, error) {
	// Define progressive dialer settings
	progressive := &genesyscloud.ProgressiveDialer{
		DialRate:       genesyscloud.PtrFloat32(0.75),
		AgentPerCall:   genesyscloud.PtrInt32(1),
		AbandonThreshold: genesyscloud.PtrFloat32(0.03), // 3% regulatory maximum
		MaxCalls:       genesyscloud.PtrInt32(50),
	}

	// Define time-of-day restrictions (business hours only)
	timeRestrictions := []genesyscloud.CampaignTimeRestriction{
		{
			StartTime: genesyscloud.PtrString("09:00:00"),
			EndTime:   genesyscloud.PtrString("17:00:00"),
			DaysOfWeek: genesyscloud.PtrStringSlice([]string{"MON", "TUE", "WED", "THU", "FRI"}),
		},
	}

	campaign := &genesyscloud.Campaign{
		Name:           genesyscloud.PtrString(name),
		CampaignType:   genesyscloud.PtrString("progressive"),
		Progressive:    progressive,
		TimeRestrictions: timeRestrictions,
		ContactList:    &genesyscloud.EntityRef{Id: genesyscloud.PtrString(contactListID)},
		WrapUpCode:     &genesyscloud.EntityRef{Id: genesyscloud.PtrString(wrapUpCodeID)},
		MaxCalls:       genesyscloud.PtrInt32(10000),
		MaxCallAttempts: genesyscloud.PtrInt32(3), // Regulatory cap
	}

	// Regulatory validation checks
	if progressive.AbandonThreshold != nil && *progressive.AbandonThreshold > 0.05 {
		return nil, fmt.Errorf("abandon threshold %.2f exceeds regulatory limit of 0.05", *progressive.AbandonThreshold)
	}
	if campaign.MaxCallAttempts != nil && *campaign.MaxCallAttempts > 3 {
		return nil, fmt.Errorf("max call attempts %d exceeds regulatory limit of 3", *campaign.MaxCallAttempts)
	}
	if len(timeRestrictions) == 0 {
		return nil, fmt.Errorf("time restrictions are mandatory for outbound compliance")
	}

	return campaign, nil
}

Required Scope: outbound:campaign:write

Step 2: Create Campaign and Poll for Activation

Campaign creation is synchronous, but the dialer engine requires time to initialize. The following function creates the campaign, then polls the status endpoint with exponential backoff until the campaign reaches ACTIVE status or fails.

import (
	"context"
	"fmt"
	"time"
)

func CreateAndActivateCampaign(ctx context.Context, apiClient *genesyscloud.APIClient, campaign *genesyscloud.Campaign) (string, error) {
	outboundAPI := genesyscloud.NewOutboundCampaignsApi(apiClient)

	resp, _, err := outboundAPI.ApiPostOutboundCampaigns(ctx, campaign)
	if err != nil {
		return "", fmt.Errorf("failed to create campaign: %w", err)
	}

	campaignID := *resp.Id

	// Polling configuration
	maxRetries := 15
	interval := time.Second * 2

	for i := 0; i < maxRetries; i++ {
		select {
		case <-ctx.Done():
			return "", ctx.Err()
		case <-time.After(interval):
		}

		statusResp, _, pollErr := outboundAPI.ApiGetOutboundCampaigns(ctx, campaignID)
		if pollErr != nil {
			if pollErr.(genesyscloud.Error).StatusCode == 429 {
				interval *= 2 // Exponential backoff for rate limits
				continue
			}
			return "", fmt.Errorf("polling failed: %w", pollErr)
		}

		if statusResp.Status != nil && *statusResp.Status == "ACTIVE" {
			return campaignID, nil
		}
		if statusResp.Status != nil && *statusResp.Status == "ERROR" {
			return "", fmt.Errorf("campaign activation failed: %s", *statusResp.Status)
		}
	}

	return "", fmt.Errorf("campaign did not reach active status within timeout")
}

Required Scope: outbound:campaign:read, outbound:campaign:write

Step 3: Implement Dynamic Dial Rate Adjustment Logic

The dialer adapts to real-time conditions. This function queries current campaign metrics, calculates the answer rate, checks available agent capacity, and updates the dialRate accordingly.

func AdjustDialRate(ctx context.Context, apiClient *genesyscloud.APIClient, campaignID string) error {
	outboundAPI := genesyscloud.NewOutboundCampaignsApi(apiClient)

	// Fetch real-time metrics
	metrics, _, err := outboundAPI.ApiGetOutboundCampaignsMetrics(ctx, campaignID)
	if err != nil {
		return fmt.Errorf("failed to fetch metrics: %w", err)
	}

	// Calculate answer rate from metrics
	totalCalls := float64(0)
	answeredCalls := float64(0)
	if metrics.Metrics != nil {
		totalCalls = float64(metrics.Metrics.TotalCalls)
		answeredCalls = float64(metrics.Metrics.AnsweredCalls)
	}

	answerRate := 0.0
	if totalCalls > 0 {
		answerRate = answeredCalls / totalCalls
	}

	// Fetch current campaign configuration
	currentCampaign, _, err := outboundAPI.ApiGetOutboundCampaigns(ctx, campaignID)
	if err != nil {
		return fmt.Errorf("failed to fetch current campaign: %w", err)
	}

	if currentCampaign.Progressive == nil {
		return fmt.Errorf("campaign is not configured as progressive")
	}

	currentRate := float32(0.5)
	if currentCampaign.Progressive.DialRate != nil {
		currentRate = *currentCampaign.Progressive.DialRate
	}

	// Dynamic adjustment logic
	var newRate float32
	if answerRate > 0.85 && metrics.Metrics.AvailableAgents > 5 {
		newRate = currentRate * 1.15 // Increase by 15%
	} else if answerRate < 0.40 || metrics.Metrics.AvailableAgents < 2 {
		newRate = currentRate * 0.85 // Decrease by 15%
	} else {
		newRate = currentRate // Maintain current rate
	}

	// Clamp rate between 0.1 and 1.0
	if newRate < 0.1 {
		newRate = 0.1
	}
	if newRate > 1.0 {
		newRate = 1.0
	}

	// Update campaign
	currentCampaign.Progressive.DialRate = &newRate
	_, _, err = outboundAPI.ApiPutOutboundCampaigns(ctx, campaignID, currentCampaign)
	if err != nil {
		return fmt.Errorf("failed to update dial rate: %w", err)
	}

	return nil
}

Required Scope: outbound:campaign:read, outbound:campaign:write

Step 4: Synchronize Metrics with External WFM via Webhooks

Capacity planning requires real-time data flow. This function registers a webhook that triggers on campaign status changes and metric updates, forwarding payloads to an external workforce management endpoint.

func RegisterWFMWebhook(ctx context.Context, apiClient *genesyscloud.APIClient, callbackURL string) error {
	webhookAPI := genesyscloud.NewWebhooksApi(apiClient)

	webhook := &genesyscloud.Webhook{
		Name:    genesyscloud.PtrString("WFM_Capacity_Sync"),
		Type:    genesyscloud.PtrString("HTTP"),
		Enabled: genesyscloud.PtrBool(true),
		Uri:     genesyscloud.PtrString(callbackURL),
		Events:  genesyscloud.PtrStringSlice([]string{"outbound.campaign.metrics", "outbound.campaign.status"}),
		Headers: map[string]string{
			"Content-Type": "application/json",
			"X-WFM-Source": "GenesysDialer",
		},
	}

	_, _, err := webhookAPI.ApiPostWebhooks(ctx, webhook)
	if err != nil {
		return fmt.Errorf("failed to create webhook: %w", err)
	}

	return nil
}

Required Scope: webhook:write

Step 5: Track Efficiency Scores and Disposition Rates

Campaign optimization relies on disposition analysis. This function queries the analytics endpoint to calculate efficiency scores and disposition breakdowns.

func GetCampaignEfficiencyAndDisposition(ctx context.Context, apiClient *genesyscloud.APIClient, campaignID string) (map[string]interface{}, error) {
	analyticsAPI := genesyscloud.NewAnalyticsApi(apiClient)

	query := map[string]interface{}{
		"view": "outbound",
		"dateFrom": time.Now().Add(-time.Hour * 24).Format(time.RFC3339),
		"dateTo":   time.Now().Format(time.RFC3339),
		"where":    fmt.Sprintf("campaignId IN (%s)", campaignID),
		"select":   []string{"disposition", "answerRate", "connectedRate"},
	}

	resp, _, err := analyticsAPI.ApiGetAnalyticsOutboundDetailsQuery(ctx, query)
	if err != nil {
		return nil, fmt.Errorf("analytics query failed: %w", err)
	}

	if resp == nil || resp.Results == nil {
		return nil, fmt.Errorf("no analytics data returned")
	}

	// Aggregate results
	metrics := make(map[string]interface{})
	totalAttempts := 0
	connected := 0
	dispositions := make(map[string]int)

	for _, row := range *resp.Results {
		if row.TotalCalls != nil {
			totalAttempts += int(*row.TotalCalls)
		}
		if row.ConnectedCalls != nil {
			connected += int(*row.ConnectedCalls)
		}
		if row.Disposition != nil {
			dispositions[*row.Disposition]++
		}
	}

	efficiencyScore := 0.0
	if totalAttempts > 0 {
		efficiencyScore = float64(connected) / float64(totalAttempts)
	}

	metrics["efficiencyScore"] = efficiencyScore
	metrics["totalAttempts"] = totalAttempts
	metrics["dispositionBreakdown"] = dispositions

	return metrics, nil
}

Required Scope: analytics:outbound:view

Step 6: Generate Dialer Audit Logs

Regulatory compliance requires immutable audit trails. This function retrieves platform audit records filtered by campaign activity.

func GenerateDialerAuditLog(ctx context.Context, apiClient *genesyscloud.APIClient, campaignID string) ([]genesyscloud.AuditRecord, error) {
	auditAPI := genesyscloud.NewAuditApi(apiClient)

	query := map[string]interface{}{
		"dateFrom": time.Now().Add(-time.Hour * 72).Format(time.RFC3339),
		"dateTo":   time.Now().Format(time.RFC3339),
		"query":    fmt.Sprintf("entityId:%s OR entityId:%s", campaignID, campaignID),
		"limit":    100,
	}

	resp, _, err := auditAPI.ApiGetPlatformAuditRecords(ctx, query)
	if err != nil {
		return nil, fmt.Errorf("audit query failed: %w", err)
	}

	if resp == nil || resp.Entities == nil {
		return []genesyscloud.AuditRecord{}, nil
	}

	return *resp.Entities, nil
}

Required Scope: audit:read

Complete Working Example

The following module integrates all components into a single DialerConfigurator struct. It handles token management, campaign lifecycle, dynamic tuning, webhook registration, analytics, and audit logging in a production-ready workflow.

	log.Printf("Campaign active with ID: %s", campaignID)

	log.Println("Step 3: Registering WFM synchronization webhook")
	if err := RegisterWFMWebhook(ctx, d.APIClient, wfmCallbackURL); err != nil {

	}
	log.Printf("Campaign metrics: %+v", metrics)

	log.Println("Step 6: Generating compliance audit log")
	auditRecords, err := GenerateDialerAuditLog(ctx, d.APIClient, campaignID)
	if err != nil {
		return fmt.Errorf("audit log generation failed: %w", err)
	}
	log.Printf("Retrieved %d audit records for compliance", len(auditRecords))

	return nil
}

func main() {

		"YOUR_CLIENT_ID",
		"YOUR_CLIENT_SECRET",
	)
	if err != nil {

	}

	if err := configurator.RunCampaignWorkflow(
		ctx,
		"Q3 Progressive Outreach",
		"CONTACT_LIST_UUID",
		"WRAPUP_CODE_UUID",
		"https://wfm.example.com/api/v1/capacity-sync",
	); err != nil {
		log.Fatalf("Workflow execution failed: %v", err)
	}

	log.Println("Dialer configuration and monitoring workflow completed successfully")
}

Common Errors & Debugging

Error: 401 Unauthorized

• Cause: Expired OAuth token, invalid client credentials, or missing oauth:clientid scope.
• Fix: Ensure the GetAccessToken function runs before every request batch. Implement token refresh logic in your deployment orchestrator. Verify the client ID and secret match the registered OAuth client in the Genesys Cloud admin console.

Error: 403 Forbidden

• Cause: The OAuth client lacks required scopes (outbound:campaign:write, analytics:outbound:view, webhook:write, audit:read).
• Fix: Navigate to the Genesys Cloud admin console, locate the OAuth client, and append the missing scopes. Regenerate the token after scope changes.

Error: 429 Too Many Requests

• Cause: Exceeding API rate limits during polling or metric queries.
• Fix: Implement exponential backoff. The CreateAndActivateCampaign function demonstrates this pattern. For high-frequency metric queries, batch requests or increase the polling interval to 5-10 seconds.

Error: 400 Bad Request

• Cause: Invalid campaign payload structure, missing required fields, or regulatory validation failure (e.g., abandonThreshold > 0.05).
• Fix: Review the BuildAndValidateCampaignPayload function. Ensure all pointers are dereferenced correctly and that time restrictions conform to ISO 8601 format. Validate JSON structure against the OpenAPI spec before submission.

Error: 404 Not Found

• Cause: Referenced contactListID, wrapUpCodeID, or campaignID does not exist in the tenant.
• Fix: Verify entity IDs using GET /api/v2/outbound/contactlists and GET /api/v2/outbound/wrapupcodes before campaign creation. Ensure the campaign ID matches the response from the creation endpoint.
