Route Genesys Cloud Post-Interaction Surveys via Go SDK with Trigger Validation and Webhook Sync

What You Will Build

• A Go service that constructs and deploys survey trigger configurations with rate limits, localization checks, and contact preference matching.
• The service uses the Genesys Cloud Survey API and Webhook API to automate routing deployment and event synchronization.
• The tutorial covers Go 1.21+ with the official go-genesyscloud-sdk v10.

Prerequisites

• OAuth client credentials with scopes: survey:view, survey:edit, webhook:admin, webhook:view
• Genesys Cloud Go SDK: github.com/mygenesys/genesyscloud/go-genesyscloud-sdk/v10/platformclientv2
• Go runtime 1.21 or higher
• Environment variables: GENESYS_CLIENT_ID, GENESYS_CLIENT_SECRET, GENESYS_BASE_PATH

Authentication Setup

The Go SDK manages OAuth token acquisition and automatic refresh. You configure the client with your credentials and required scopes. The SDK caches the token in memory and refreshes it before expiration.

package main

import (
	"context"
	"fmt"
	"os"
	"time"

	"github.com/mygenesys/genesyscloud/go-genesyscloud-sdk/v10/platformclientv2"
)

func initSurveyClient(ctx context.Context) (*platformclientv2.ApiClient, error) {
	config := platformclientv2.Configuration{
		ClientId:     os.Getenv("GENESYS_CLIENT_ID"),
		ClientSecret: os.Getenv("GENESYS_CLIENT_SECRET"),
		BasePath:     os.Getenv("GENESYS_BASE_PATH"),
		Scopes:       []string{"survey:view", "survey:edit", "webhook:admin", "webhook:view"},
	}

	apiClient, err := platformclientv2.NewApiClient(config)
	if err != nil {
		return nil, fmt.Errorf("failed to initialize API client: %w", err)
	}

	// Trigger initial token fetch
	_, err = apiClient.GetAuthClient().GetToken(ctx)
	if err != nil {
		return nil, fmt.Errorf("failed to acquire OAuth token: %w", err)
	}

	return apiClient, nil
}

OAuth Scopes Required: survey:view, survey:edit, webhook:admin, webhook:view

Implementation

Step 1: Initialize Survey API Client and Validate Pagination

List existing surveys to verify the client can communicate with the platform. The endpoint supports pagination via pageSize and pageNumber.

func listSurveys(ctx context.Context, apiClient *platformclientv2.ApiClient) ([]platformclientv2.Survey, error) {
	surveyApi := platformclientv2.NewSurveyApi(apiClient)
	var allSurveys []platformclientv2.Survey
	pageSize := 25
	pageNumber := 1

	for {
		result, _, err := surveyApi.GetSurveys(ctx, pageNumber, pageSize, "", "", "", "")
		if err != nil {
			return nil, fmt.Errorf("failed to fetch surveys: %w", err)
		}

		if result.Entities == nil {
			break
		}
		allSurveys = append(allSurveys, *result.Entities...)

		if pageNumber >= *result.PageCount {
			break
		}
		pageNumber++
	}

	return allSurveys, nil
}

HTTP Equivalent:

GET /api/v2/surveys?pageSize=25&pageNumber=1 HTTP/1.1
Host: api.mypurecloud.com
Authorization: Bearer <oauth_token>

HTTP/1.1 200 OK
{
  "entities": [
    {
      "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
      "name": "Post-Call CSAT",
      "enabled": true
    }
  ],
  "pageSize": 25,
  "pageNumber": 1,
  "pageCount": 1,
  "total": 1
}

Step 2: Construct and Validate Trigger Payload Against Engine Constraints

Build the survey trigger configuration. The payload must respect engine constraints: maximum invitation rate, valid localization codes, and contact preference alignment. The validation function checks opt-in status and channel compatibility before returning the structured payload.

type TriggerConfig struct {
	SurveyId            string
	InvitationType      string // "email", "sms", "web", "voice"
	Language            string
	MaxInvitationsPerDay int
	Enabled             bool
	OptInRequired       bool
}

func validateTriggerConfig(cfg TriggerConfig) error {
	if cfg.InvitationType != "email" && cfg.InvitationType != "sms" && cfg.InvitationType != "web" {
		return fmt.Errorf("unsupported invitation type: %s", cfg.InvitationType)
	}

	if cfg.Language != "en-US" && cfg.Language != "es-ES" && cfg.Language != "fr-FR" {
		return fmt.Errorf("localization not available: %s", cfg.Language)
	}

	if cfg.MaxInvitationsPerDay > 5000 || cfg.MaxInvitationsPerDay < 1 {
		return fmt.Errorf("maxInvitationsPerDay must be between 1 and 5000 to prevent routing failure")
	}

	if cfg.OptInRequired && cfg.InvitationType == "sms" {
		// Simulated opt-in pipeline check
		if !checkContactOptInStatus(cfg.SurveyId) {
			return fmt.Errorf("contact preference opt-in status is false; routing blocked to prevent survey fatigue")
		}
	}

	return nil
}

func checkContactOptInStatus(surveyId string) bool {
	// In production, query your CRM or Genesys contact database here
	return true
}

func buildTriggerPayload(cfg TriggerConfig) platformclientv2.SurveyTrigger {
	enabled := cfg.Enabled
	triggerType := "interaction"
	triggerCondition := "completed"

	surveyRef := platformclientv2.SurveyTriggerSurvey{
		Id: &cfg.SurveyId,
	}

	return platformclientv2.SurveyTrigger{
		TriggerType:          &triggerType,
		TriggerCondition:     &triggerCondition,
		Enabled:              &enabled,
		MaxInvitationsPerDay: &cfg.MaxInvitationsPerDay,
		Language:             &cfg.Language,
		InvitationType:       &cfg.InvitationType,
		Surveys:              &[]platformclientv2.SurveyTriggerSurvey{surveyRef},
	}
}

Request Body Schema:

{
  "triggerType": "interaction",
  "triggerCondition": "completed",
  "enabled": true,
  "maxInvitationsPerDay": 500,
  "language": "en-US",
  "invitationType": "email",
  "surveys": [
    {
      "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890"
    }
  ]
}

Step 3: Execute Atomic PUT with Retry Logic and Latency Tracking

Deploy the trigger configuration using an atomic PUT operation. The function implements exponential backoff for 429 rate limit responses, tracks routing latency, and logs audit entries for governance.

import (
	"log/slog"
	"net/http"
	"strconv"
	"time"
)

type AuditEntry struct {
	Timestamp    time.Time
	SurveyId     string
	Operation    string
	LatencyMs    float64
	Success      bool
	StatusCode   int
	ErrorMessage string
}

func deploySurveyTrigger(ctx context.Context, apiClient *platformclientv2.ApiClient, cfg TriggerConfig, auditLog *[]AuditEntry) error {
	if err := validateTriggerConfig(cfg); err != nil {
		return fmt.Errorf("validation failed: %w", err)
	}

	trigger := buildTriggerPayload(cfg)
	surveyApi := platformclientv2.NewSurveyApi(apiClient)

	startTime := time.Now()
	maxRetries := 3

	for attempt := 0; attempt <= maxRetries; attempt++ {
		_, httpResponse, err := surveyApi.UpdateSurveyTrigger(ctx, cfg.SurveyId, trigger)
		latency := time.Since(startTime).Milliseconds()

		if err != nil {
			statusCode := 0
			if httpResponse != nil {
				statusCode = httpResponse.StatusCode
			}

			entry := AuditEntry{
				Timestamp:   time.Now(),
				SurveyId:    cfg.SurveyId,
				Operation:   "PUT /api/v2/surveys/{surveyId}/trigger",
				LatencyMs:   float64(latency),
				Success:     false,
				StatusCode:  statusCode,
				ErrorMessage: err.Error(),
			}
			*auditLog = append(*auditLog, entry)

			if httpResponse != nil && httpResponse.StatusCode == http.StatusTooManyRequests {
				retryAfter := httpResponse.Header.Get("Retry-After")
				seconds, _ := strconv.Atoi(retryAfter)
				if seconds == 0 {
					seconds = 2 << attempt
				}
				slog.Warn("rate limit hit, retrying", "attempt", attempt, "retry_after", seconds)
				time.Sleep(time.Duration(seconds) * time.Second)
				continue
			}

			return fmt.Errorf("failed to update survey trigger: %w", err)
		}

		entry := AuditEntry{
			Timestamp:  time.Now(),
			SurveyId:   cfg.SurveyId,
			Operation:  "PUT /api/v2/surveys/{surveyId}/trigger",
			LatencyMs:  float64(latency),
			Success:    true,
			StatusCode: http.StatusOK,
		}
		*auditLog = append(*auditLog, entry)
		slog.Info("survey trigger deployed successfully", "survey_id", cfg.SurveyId, "latency_ms", latency)
		return nil
	}

	return fmt.Errorf("max retries exceeded for survey trigger deployment")
}

HTTP Equivalent:

PUT /api/v2/surveys/a1b2c3d4-e5f6-7890-abcd-ef1234567890/trigger HTTP/1.1

  "enabled": true,
  "maxInvitationsPerDay": 500,
  "language": "en-US",
  "invitationType": "email",
  "surveys": [{"id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890"}]
}

HTTP/1.1 200 OK
{
  "id": "trigger-12345678-90ab-cdef-1234-567890abcdef",

  "invitationType": "email",
  "surveys": [{"id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890"}]
}

Step 4: Configure Survey Routed Webhooks for External Analytics Sync

Register webhooks to synchronize routing events with external analytics platforms. The webhook captures invitation dispatch and response completion events.

func setupSurveyWebhooks(ctx context.Context, apiClient *platformclientv2.ApiClient, webhookUrl string) error {
	webhookApi := platformclientv2.NewWebhookApi(apiClient)

	enabled := true
	enabled2 := true
	priority := 1
	status := "active"
	event := "survey.invitation.sent"
	event2 := "survey.response.completed"

	webhook := platformclientv2.Webhook{
		Name:          platformclientv2.PtrString("SurveyRoutingSync"),
		Enabled:       &enabled,
		Enabled2:      &enabled2,
		Priority:      &priority,
		Status:        &status,
		Events:        &[]string{event, event2},
		Uri:           platformclientv2.PtrString(webhookUrl),
		Method:        platformclientv2.PtrString("POST"),
		ContentType:   platformclientv2.PtrString("application/json"),
		Header: map[string]string{
			"X-Genesys-Event": "survey-routing",
		},
	}

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

	if httpResponse.StatusCode != http.StatusCreated {
		return fmt.Errorf("unexpected status code %d for webhook creation", httpResponse.StatusCode)
	}

	slog.Info("survey routed webhooks configured successfully")
	return nil
}

HTTP Equivalent:

POST /api/v2/webhooks HTTP/1.1
Host: api.mypurecloud.com
Authorization: Bearer <oauth_token>
Content-Type: application/json

{
  "name": "SurveyRoutingSync",
  "enabled": true,

  "status": "active",
  "events": ["survey.invitation.sent", "survey.response.completed"],
  "uri": "https://analytics.example.com/genesys/survey-events",
  "method": "POST",
  "contentType": "application/json",
  "header": {
    "X-Genesys-Event": "survey-routing"
  }
}

Common Errors & Debugging

Error: 400 Bad Request (Invalid Trigger Matrix or Schema)

• Cause: The SurveyTrigger payload contains unsupported values for triggerType, invitationType, or exceeds maxInvitationsPerDay engine limits.
• Fix: Validate the payload against the schema before sending. Ensure maxInvitationsPerDay stays within 1 to 5000. Verify language matches a supported locale in your Genesys tenant.
• Code Fix: The validateTriggerConfig function enforces these constraints before the API call.

Error: 401 Unauthorized or 403 Forbidden

• Cause: OAuth token expired, revoked, or missing required scopes.
• Fix: Verify the client credentials. Ensure the OAuth client has survey:edit and webhook:admin scopes assigned in the Genesys Cloud admin console. The SDK refreshes tokens automatically, but initial token acquisition must succeed.
• Code Fix: Check initSurveyClient error returns. Log the exact HTTP status and response body to identify missing scopes.

Error: 429 Too Many Requests

• Cause: Rate limit cascade triggered by rapid successive PUT operations or webhook event floods.
• Fix: Implement exponential backoff. Parse the Retry-After header from the response.
• Code Fix: The deploySurveyTrigger function handles 429 responses by reading Retry-After, falling back to 2 << attempt seconds, and retrying up to three times.

Error: 404 Not Found

• Cause: The surveyId does not exist in the tenant or the user lacks survey:view permissions for that specific resource.
• Fix: Verify the survey ID using GET /api/v2/surveys/{surveyId}. Confirm the OAuth client has access to the organization or environment containing the survey.
• Code Fix: Add a pre-flight GetSurvey call to verify existence before attempting the trigger update.
