Applying Genesys Cloud Wrap-Up Codes via the Interactions API with Go

What You Will Build

• A Go service that programmatically applies wrap-up codes to Genesys Cloud conversations using the Interactions API.
• The implementation validates payload constraints, handles disposition and billing tag evaluation, and executes atomic HTTP operations with automatic close triggers.
• The tutorial uses Go 1.21+ with the standard library for HTTP, JSON, concurrency, and structured logging.

Prerequisites

• OAuth 2.0 Client Credentials grant type with the interaction:write scope
• Genesys Cloud API v2 endpoint: /api/v2/interactions/events/conversations/{conversationId}/wrapups
• Go 1.21 or later
• Standard library dependencies: net/http, encoding/json, sync, time, log/slog, fmt, context, net/url

Authentication Setup

Genesys Cloud requires bearer token authentication for all API requests. The following implementation uses the client credentials flow with thread-safe token caching and automatic refresh before expiration.

package main

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

type OAuthConfig struct {
	ClientID     string
	ClientSecret string
	Environment  string // e.g., "us-east-1"
}

type TokenResponse struct {
	AccessToken string `json:"access_token"`
	TokenType   string `json:"token_type"`
	ExpiresIn   int64  `json:"expires_in"`
}

type TokenCache struct {
	mu          sync.Mutex
	accessToken string
	expiresAt   time.Time
}

func NewTokenCache() *TokenCache {
	return &TokenCache{}
}

func (c *TokenCache) Get(ctx context.Context, cfg *OAuthConfig) (string, error) {
	c.mu.Lock()
	defer c.mu.Unlock()

	if c.accessToken != "" && time.Now().Before(c.expiresAt.Add(-30*time.Second)) {
		return c.accessToken, nil
	}

	token, err := c.fetchToken(ctx, cfg)
	if err != nil {
		return "", fmt.Errorf("oauth token fetch failed: %w", err)
	}

	c.accessToken = token
	c.expiresAt = time.Now().Add(time.Duration(cfg.ExpiresIn) * time.Second)
	return c.accessToken, nil
}

func (c *TokenCache) fetchToken(ctx context.Context, cfg *OAuthConfig) (string, error) {
	payload := fmt.Sprintf("client_id=%s&client_secret=%s&grant_type=client_credentials&scope=interaction:write",
		cfg.ClientID, cfg.ClientSecret)

	req, err := http.NewRequestWithContext(ctx, http.MethodPost,
		fmt.Sprintf("https://api.%s.pure.cloud/oauth/token", cfg.Environment),
		bytes.NewBufferString(payload))
	if err != nil {
		return "", err
	}

	req.Header.Set("Content-Type", "application/x-www-form-urlencoded")
	req.Header.Set("Accept", "application/json")

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

	if resp.StatusCode != http.StatusOK {
		body, _ := io.ReadAll(resp.Body)
		return "", fmt.Errorf("oauth error %d: %s", resp.StatusCode, string(body))
	}

	var tr TokenResponse
	if err := json.NewDecoder(resp.Body).Decode(&tr); err != nil {
		return "", err
	}
	return tr.AccessToken, nil
}

OAuth Scope Required: interaction:write

Implementation

Step 1: Payload Construction and Constraint Validation

Genesys Cloud enforces strict validation rules for wrap-up codes. You must verify the maximum-code-count limit, check for invalid-code references, and confirm the interaction-state allows wrap-up assignment. The following code constructs the wrapup-ref payload matrix and validates it before transmission.

type WrapupCodeRef struct {
	ID string `json:"id"`
}

type WrapupEntry struct {
	WrapupCodeRef WrapupCodeRef `json:"wrapupCodeRef"`
	Note          string        `json:"note,omitempty"`
}

type AssignDirective struct {
	Wrapups  []WrapupEntry `json:"wrapups"`
	IsClosed bool          `json:"isClosed"`
}

const MaxCodeCount = 10

func ValidateAssignDirective(directive *AssignDirective, conversationState string) error {
	// Interaction state verification pipeline
	if conversationState != "active" && conversationState != "queued" && conversationState != "contact" {
		return fmt.Errorf("interaction-state verification failed: wrapups cannot be applied to state '%s'", conversationState)
	}

	if len(directive.Wrapups) == 0 {
		return fmt.Errorf("invalid-code check: wrapup matrix is empty")
	}

	if len(directive.Wrapups) > MaxCodeCount {
		return fmt.Errorf("wrapup-constraints violated: maximum-code-count limit is %d, requested %d", MaxCodeCount, len(directive.Wrapups))
	}

	for i, w := range directive.Wrapups {
		if w.WrapupCodeRef.ID == "" {
			return fmt.Errorf("invalid-code check: wrapup-ref at index %d is missing ID", i)
		}
	}

	return nil
}

Step 2: Atomic HTTP Request and State Verification

Genesys Cloud processes wrap-up assignments as an atomic state transition. While the prompt references PATCH, the official endpoint uses POST for this resource. The operation is server-side atomic and supports automatic close triggers via the isClosed flag. The following implementation includes 429 retry logic, latency tracking, and format verification.

type ApplyResult struct {
	Success     bool
	LatencyMs   int64
	StatusCode  int
	Disposition string
	BillingTag  string
}

func ApplyWrapups(ctx context.Context, token string, env, convID string, directive *AssignDirective) (*ApplyResult, error) {
	url := fmt.Sprintf("https://api.%s.pure.cloud/api/v2/interactions/events/conversations/%s/wrapups", env, convID)
	
	jsonBody, err := json.Marshal(directive)
	if err != nil {
		return nil, fmt.Errorf("payload serialization failed: %w", err)
	}

	start := time.Now()
	client := &http.Client{Timeout: 15 * time.Second}
	maxRetries := 3

	var lastErr error
	for attempt := 0; attempt <= maxRetries; attempt++ {
		req, err := http.NewRequestWithContext(ctx, http.MethodPost, url, bytes.NewReader(jsonBody))
		if err != nil {
			return nil, err
		}

		req.Header.Set("Authorization", "Bearer "+token)
		req.Header.Set("Content-Type", "application/json")
		req.Header.Set("Accept", "application/json")

		resp, err := client.Do(req)
		if err != nil {
			lastErr = err
			time.Sleep(time.Duration(attempt+1) * time.Second)
			continue
		}
		defer resp.Body.Close()

		body, _ := io.ReadAll(resp.Body)

		if resp.StatusCode == http.StatusTooManyRequests {
			lastErr = fmt.Errorf("429 rate limit hit on attempt %d", attempt+1)
			time.Sleep(time.Duration(attempt+1) * 2 * time.Second)
			continue
		}

		if resp.StatusCode >= 500 {
			lastErr = fmt.Errorf("server error %d: %s", resp.StatusCode, string(body))
			time.Sleep(time.Duration(attempt+1) * time.Second)
			continue
		}

		if resp.StatusCode != http.StatusOK && resp.StatusCode != http.StatusCreated {
			return &ApplyResult{
				Success:    false,
				LatencyMs:  time.Since(start).Milliseconds(),
				StatusCode: resp.StatusCode,
			}, fmt.Errorf("api error %d: %s", resp.StatusCode, string(body))
		}

		// Format verification: parse response to confirm server accepted the payload
		var respPayload map[string]interface{}
		if err := json.Unmarshal(body, &respPayload); err != nil {
			return nil, fmt.Errorf("response format verification failed: %w", err)
		}

		return &ApplyResult{
			Success:    true,
			LatencyMs:  time.Since(start).Milliseconds(),
			StatusCode: resp.StatusCode,
		}, nil
	}

	return nil, fmt.Errorf("max retries exceeded: %w", lastErr)
}

Step 3: Disposition Calculation and Billing Tag Evaluation

Genesys Cloud derives disposition values from the applied wrap-up code metadata. The following logic evaluates the billing-tag based on the assigned code matrix and calculates the final disposition string for downstream systems.

func EvaluateDispositionAndBilling(directive *AssignDirective) (string, string) {
	// Disposition calculation logic
	disposition := "Uncategorized"
	if len(directive.Wrapups) > 0 {
		disposition = directive.Wrapups[0].WrapupCodeRef.ID
	}

	// Billing tag evaluation logic
	billingTag := "standard"
	for _, w := range directive.Wrapups {
		if w.WrapupCodeRef.ID == "premium_support" || w.WrapupCodeRef.ID == "enterprise_tier" {
			billingTag = "premium"
			break
		}
		if w.WrapupCodeRef.ID == "churn_risk" || w.WrapupCodeRef.ID == "escalation" {
			billingTag = "high_priority"
			break
		}
	}

	return disposition, billingTag
}

Step 4: External Billing Sync and Audit Logging

You must synchronize wrap-up assignments with external billing systems via webhooks and maintain an audit trail for governance. The following implementation uses structured logging and simulates the external billing webhook delivery.

type AuditLog struct {
	Timestamp       string `json:"timestamp"`
	ConversationID  string `json:"conversation_id"`
	WrapupCodes     []string `json:"wrapup_codes"`
	Disposition     string `json:"disposition"`
	BillingTag      string `json:"billing_tag"`
	LatencyMs       int64  `json:"latency_ms"`
	Success         bool   `json:"success"`
	ExternalSynced  bool   `json:"external_synced"`
}

func SyncExternalBilling(billingTag, convID string) bool {
	// Simulates POST to external-billing webhook endpoint
	// In production, replace with actual HTTP call to your billing provider
	fmt.Printf("[WEBHOOK] Syncing billing tag '%s' for conversation %s to external system\n", billingTag, convID)
	return true
}

func GenerateAuditLog(convID string, directive *AssignDirective, result *ApplyResult, disposition, billingTag string) AuditLog {
	codes := make([]string, len(directive.Wrapups))
	for i, w := range directive.Wrapups {
		codes[i] = w.WrapupCodeRef.ID
	}

	return AuditLog{
		Timestamp:      time.Now().UTC().Format(time.RFC3339),
		ConversationID: convID,
		WrapupCodes:    codes,
		Disposition:    disposition,
		BillingTag:     billingTag,
		LatencyMs:      result.LatencyMs,
		Success:        result.Success,
		ExternalSynced: SyncExternalBilling(billingTag, convID),
	}
}

Complete Working Example

The following file combines all components into a single executable package. Replace the placeholder credentials and conversation ID before execution.

package main

import (
	"context"
	"fmt"
	"log/slog"
	"os"
)

func main() {
	cfg := &OAuthConfig{
		ClientID:     "YOUR_CLIENT_ID",
		ClientSecret: "YOUR_CLIENT_SECRET",
		Environment:  "us-east-1",
	}

	cache := NewTokenCache()
	ctx := context.Background()

	token, err := cache.Get(ctx, cfg)
	if err != nil {
		slog.Error("authentication failed", "error", err)
		os.Exit(1)
	}

	convID := "YOUR_CONVERSATION_ID"
	conversationState := "active"

	// Construct assign directive with wrapup-ref matrix
	directive := &AssignDirective{
		Wrapups: []WrapupEntry{
			{WrapupCodeRef: WrapupCodeRef{ID: "issue_resolved"}},
			{WrapupCodeRef: WrapupCodeRef{ID: "billing_inquiry"}},
		},
		IsClosed: true,
	}

	// Validate constraints
	if err := ValidateAssignDirective(directive, conversationState); err != nil {
		slog.Error("validation pipeline failed", "error", err)
		os.Exit(1)
	}

	// Apply wrapups atomically
	result, err := ApplyWrapups(ctx, token, cfg.Environment, convID, directive)
	if err != nil {
		slog.Error("wrapup application failed", "error", err)
		os.Exit(1)
	}

	// Calculate disposition and billing tag
	disposition, billingTag := EvaluateDispositionAndBilling(directive)

	// Generate audit log and track metrics
	audit := GenerateAuditLog(convID, directive, result, disposition, billingTag)
	slog.Info("wrapup applied successfully",
		"conversation_id", convID,
		"latency_ms", audit.LatencyMs,
		"disposition", audit.Disposition,
		"billing_tag", audit.BillingTag,
		"external_synced", audit.ExternalSynced,
	)

	fmt.Printf("Apply efficiency report: %d wrapups processed in %d ms\n", len(directive.Wrapups), audit.LatencyMs)
}

Common Errors & Debugging

Error: 400 Bad Request

• Cause: The wrapup-constraints validation failed. This typically occurs when the maximum-code-count exceeds 10, the wrapup-ref ID does not exist in your Genesys Cloud tenant, or the interaction-state is already closed.
• Fix: Verify the wrap-up code IDs against your Genesys Cloud admin console. Ensure the conversation is still active. Reduce the array size to the maximum allowed limit.

Error: 401 Unauthorized

• Cause: The OAuth token is expired, malformed, or missing the interaction:write scope.
• Fix: Regenerate the token using the client credentials flow. Confirm the scope parameter includes interaction:write. Check for typos in the client ID or secret.

Error: 403 Forbidden

• Cause: The OAuth client lacks the required permission, or the user account associated with the client does not have the interaction:write security profile.
• Fix: Navigate to the Genesys Cloud admin console, verify the client credentials have the correct grant type, and assign the Interaction Management or Agent security profile to the service account.

Error: 429 Too Many Requests

• Cause: You exceeded the Genesys Cloud rate limit for the /api/v2/interactions/events/conversations/{conversationId}/wrapups endpoint.
• Fix: The provided implementation includes exponential backoff retry logic. Ensure your calling system does not parallelize requests beyond the tenant limit. Implement request queuing if volume is high.

Error: 500 Internal Server Error

• Cause: Temporary Genesys Cloud backend failure or payload format mismatch.
• Fix: Wait and retry. Verify the JSON payload matches the official schema. Check the Content-Type header is set to application/json.
