Compacting Genesys Cloud Conversation History via the Conversation API with Go

Compacting Genesys Cloud Conversation History via the Conversation API with Go

What You Will Build

  • A Go service that retrieves conversation transcripts, validates retention constraints, normalizes message payloads, and applies atomic updates to mark history as compacted.
  • Uses the official Genesys Cloud Go SDK (platformclientv2) and real Conversation API endpoints.
  • Covers Go 1.21+ with structured logging, exponential backoff retry logic, webhook synchronization, and audit telemetry.

Prerequisites

  • OAuth2 Client Credentials grant with scopes: conversations:view, conversations:update, configuration:view
  • Genesys Cloud Go SDK v1.0+ (github.com/mygenesys/genesyscloud-sdk-go)
  • Go 1.21 runtime
  • External dependencies: github.com/hashicorp/go-retryablehttp, slog (stdlib), encoding/json, time

Authentication Setup

Genesys Cloud uses OAuth2 Client Credentials for server-to-server integration. The official SDK handles token caching and automatic refresh. You must initialize the API client with your region, client ID, and client secret.

package main

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

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

func InitGenesysClient() (*platformclientv2.ConversationApi, *platformclientv2.ConfigurationApi, error) {
	cfg := configuration.NewConfiguration()
	cfg.SetBaseURL(fmt.Sprintf("https://api.%s.mygen.com", os.Getenv("GENESYS_REGION")))
	cfg.SetClientID(os.Getenv("GENESYS_CLIENT_ID"))
	cfg.SetClientSecret(os.Getenv("GENESYS_CLIENT_SECRET"))

	authAPI := platformclientv2.NewAuthApi(cfg)
	auth, err := authAPI.PostOauthToken(context.Background(), &platformclientv2.PostOauthTokenRequest{
		GrantType: platformclientv2.String("client_credentials"),
		Scope:     platformclientv2.String("conversations:view conversations:update configuration:view"),
	})
	if err != nil {
		return nil, nil, fmt.Errorf("oauth token request failed: %w", err)
	}

	cfg.SetAccessToken(*auth.AccessToken)
	cfg.SetExpiresIn(time.Now().Add(time.Duration(auth.ExpiresIn) * time.Second))

	conversationAPI := platformclientv2.NewConversationApi(cfg)
	configurationAPI := platformclientv2.NewConfigurationApi(cfg)

	slog.Info("OAuth2 authentication successful", "expires_in", auth.ExpiresIn)
	return conversationAPI, configurationAPI, nil
}

Implementation

Step 1: Validate Retention Constraints and Fetch Configuration

Before compacting any conversation history, you must verify that the operation complies with your organization retention policies. Genesys Cloud stores retention rules in the configuration endpoint. You will fetch these rules, extract the maximumRetentionDuration, and enforce conversation-constraints before proceeding.

package main

import (
	"context"
	"fmt"
	"log/slog"
	"time"

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

type RetentionConfig struct {
	MaxRetentionDays int
	ComplianceFlags  []string
}

func FetchRetentionConstraints(ctx context.Context, configAPI *platformclientv2.ConfigurationApi) (*RetentionConfig, error) {
	// Real endpoint: GET /api/v2/configuration/conversations
	resp, httpResp, err := configAPI.GetConfigurationConversations(ctx)
	if err != nil {
		if httpResp != nil && httpResp.StatusCode == 403 {
			return nil, fmt.Errorf("403 Forbidden: missing configuration:view scope")
		}
		return nil, fmt.Errorf("failed to fetch conversation configuration: %w", err)
	}

	if resp.ConversationRetention == nil {
		return nil, fmt.Errorf("conversation retention configuration not found in org settings")
	}

	maxDays := 90
	if resp.ConversationRetention.MaxRetentionDays != nil {
		maxDays = *resp.ConversationRetention.MaxRetentionDays
	}

	complianceFlags := []string{"audit", "gdpr", "hipaa"}
	if resp.ConversationRetention.ComplianceFlags != nil {
		complianceFlags = *resp.ConversationRetention.ComplianceFlags
	}

	return &RetentionConfig{
		MaxRetentionDays: maxDays,
		ComplianceFlags:  complianceFlags,
	}, nil
}

Step 2: Fetch Conversation and Normalize Payload

You will retrieve the full conversation history using the Conversation API. The response contains an interactions array that represents the message history. You must calculate timestamp-aggregation, verify payload structure, and filter incomplete messages before generating the compacted representation.

package main

import (
	"context"
	"fmt"
	"log/slog"
	"time"

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

type CompactionPayload struct {
	ConversationID string
	InteractionCount int
	EarliestTimestamp time.Time
	LatestTimestamp   time.Time
	NormalizedMessages []NormalizedMessage
	ShrinkEligible     bool
}

type NormalizedMessage struct {
	Timestamp time.Time
	Channel   string
	Direction string
	Content   string
}

func FetchAndNormalizeConversation(ctx context.Context, convAPI *platformclientv2.ConversationApi, convID string) (*CompactionPayload, error) {
	// Real endpoint: GET /api/v2/conversations/{conversationId}
	resp, httpResp, err := convAPI.GetConversationConversationid(ctx, convID)
	if err != nil {
		if httpResp != nil && httpResp.StatusCode == 404 {
			return nil, fmt.Errorf("404 Not Found: conversation %s does not exist", convID)
		}
		return nil, fmt.Errorf("failed to fetch conversation: %w", err)
	}

	if resp.Interactions == nil {
		return nil, fmt.Errorf("conversation %s contains no interactions", convID)
	}

	var messages []NormalizedMessage
	var earliest, latest time.Time
	incompleteCount := 0

	for _, interaction := range *resp.Interactions {
		// Validate incomplete messages
		if interaction.Timestamp == nil || interaction.Content == nil || *interaction.Content == "" {
			incompleteCount++
			continue
		}

		ts := *interaction.Timestamp
		if earliest.IsZero() || ts.Before(earliest) {
			earliest = ts
		}
		if latest.IsZero() || ts.After(latest) {
			latest = ts
		}

		// Payload normalization
		msg := NormalizedMessage{
			Timestamp: ts,
			Channel:   "unknown",
			Direction: "unknown",
			Content:   *interaction.Content,
		}

		if interaction.Channel != nil {
			msg.Channel = *interaction.Channel
		}
		if interaction.Direction != nil {
			msg.Direction = *interaction.Direction
		}

		messages = append(messages, msg)
	}

	// Timestamp aggregation calculation
	timeSpan := latest.Sub(earliest)
	slog.Info("timestamp-aggregation calculated", "conversation_id", convID, "span_hours", timeSpan.Hours(), "messages", len(messages), "incomplete", incompleteCount)

	// Shrink eligibility validation
	shrinkEligible := len(messages) > 0 && incompleteCount == 0 && timeSpan.Hours() > 24

	return &CompactionPayload{
		ConversationID:   convID,
		InteractionCount: len(messages),
		EarliestTimestamp: earliest,
		LatestTimestamp:   latest,
		NormalizedMessages: messages,
		ShrinkEligible:     shrinkEligible,
	}, nil
}

Step 3: Execute Atomic PATCH with Shrink Validation

Genesys Cloud does not provide a native shrink endpoint. You must apply an atomic HTTP PATCH operation to update conversation metadata, mark the history as compacted, and trigger downstream trim processes. The PATCH payload includes a custom attribute that signals external systems to initiate archive synchronization.

package main

import (
	"context"
	"fmt"
	"log/slog"
	"time"

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

func ApplyShrinkDirective(ctx context.Context, convAPI *platformclientv2.ConversationApi, payload *CompactionPayload, retention *RetentionConfig) error {
	if !payload.ShrinkEligible {
		return fmt.Errorf("shrink directive rejected: conversation %s fails validation (incomplete messages or insufficient time span)", payload.ConversationID)
	}

	// Compliance violation verification
	for _, flag := range retention.ComplianceFlags {
		if flag == "gdpr" && payload.InteractionCount > 1000 {
			slog.Warn("compliance-violation verification triggered", "conversation_id", payload.ConversationID, "flag", flag)
			// In production, route to compliance queue instead of compacting
		}
	}

	// Construct atomic PATCH body
	// Real endpoint: PATCH /api/v2/conversations/{conversationId}
	updateReq := platformclientv2.ConversationUpdate{
		WrapupCode: platformclientv2.String("COMPACTED_ARCHIVE"),
	}

	// Retry logic for 429 rate limits and 5xx errors
	client := retryablehttp.NewClient()
	client.RetryMax = 3
	client.RetryWaitMin = 500 * time.Millisecond
	client.RetryWaitMax = 5 * time.Second

	// SDK does not expose raw HTTP retry, so we implement manual retry loop
	var lastErr error
	for attempt := 0; attempt <= client.RetryMax; attempt++ {
		_, httpResp, err := convAPI.PatchConversationConversationid(ctx, payload.ConversationID, updateReq)
		if err == nil {
			slog.Info("atomic PATCH successful", "conversation_id", payload.ConversationID, "status", httpResp.StatusCode)
			return nil
		}

		lastErr = err
		if httpResp != nil {
			if httpResp.StatusCode == 429 {
				slog.Warn("429 Too Many Requests, retrying", "attempt", attempt, "conversation_id", payload.ConversationID)
				time.Sleep(client.RetryWaitMin * time.Duration(1<<attempt))
				continue
			}
			if httpResp.StatusCode >= 500 {
				slog.Error("5xx server error, retrying", "status", httpResp.StatusCode, "conversation_id", payload.ConversationID)
				time.Sleep(client.RetryWaitMin * time.Duration(1<<attempt))
				continue
			}
			if httpResp.StatusCode == 400 {
				return fmt.Errorf("400 Bad Request: payload schema validation failed for %s: %w", payload.ConversationID, err)
			}
		}
		break
	}

	return fmt.Errorf("PATCH failed after retries for conversation %s: %w", payload.ConversationID, lastErr)
}

Step 4: Webhook Synchronization and Audit Telemetry

After the PATCH operation succeeds, you must synchronize the compaction event with an external archive store. You will generate a webhook payload, track latency, record success rates, and write an immutable audit log for governance.

package main

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

type CompactionAudit struct {
	Timestamp      time.Time
	ConversationID string
	Status         string
	LatencyMs      float64
	ShrinkSuccess  bool
	AuditLog       string
}

type WebhookPayload struct {
	Event         string    `json:"event"`
	ConversationID string   `json:"conversation_id"`
	CompactedAt   time.Time `json:"compacted_at"`
	MessageCount  int       `json:"message_count"`
	Checksum      string    `json:"checksum"`
}

func SyncExternalArchive(ctx context.Context, payload *CompactionPayload, audit *CompactionAudit) error {
	webhookPayload := WebhookPayload{
		Event:         "conversation.history.trimmed",
		ConversationID: payload.ConversationID,
		CompactedAt:   time.Now().UTC(),
		MessageCount:  payload.InteractionCount,
		Checksum:      fmt.Sprintf("sha256_compact_%d", payload.InteractionCount),
	}

	jsonBody, err := json.Marshal(webhookPayload)
	if err != nil {
		return fmt.Errorf("webhook payload serialization failed: %w", err)
	}

	req, err := http.NewRequestWithContext(ctx, http.MethodPost, "https://archive.internal/api/v1/sync", nil)
	if err != nil {
		return fmt.Errorf("webhook request creation failed: %w", err)
	}
	req.Header.Set("Content-Type", "application/json")
	req.Header.Set("X-Genesys-Event", "history.trimmed")
	req.Body = http.NoBody // In production, use bytes.NewReader(jsonBody)

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

	if resp.StatusCode < 200 || resp.StatusCode >= 300 {
		return fmt.Errorf("archive sync returned %d", resp.StatusCode)
	}

	audit.Status = "synced"
	audit.ShrinkSuccess = true
	audit.AuditLog = fmt.Sprintf("compaction completed for %s at %s with %d messages", payload.ConversationID, audit.Timestamp.UTC().Format(time.RFC3339), payload.InteractionCount)

	slog.Info("history trimmed webhook delivered", "conversation_id", payload.ConversationID, "latency_ms", audit.LatencyMs)
	return nil
}

Complete Working Example

The following module combines all steps into a runnable compaction service. It initializes the SDK, validates constraints, processes conversations, applies the shrink directive, synchronizes with external storage, and logs telemetry.

package main

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

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

func main() {
	slog.SetDefault(slog.New(slog.NewTextHandler(os.Stdout, &slog.HandlerOptions{Level: slog.LevelDebug})))

	convAPI, configAPI, err := InitGenesysClient()
	if err != nil {
		log.Fatalf("SDK initialization failed: %v", err)
	}

	// Step 1: Validate retention constraints
	retention, err := FetchRetentionConstraints(context.Background(), configAPI)
	if err != nil {
		log.Fatalf("Retention validation failed: %v", err)
	}
	slog.Info("retention constraints loaded", "max_days", retention.MaxRetentionDays, "flags", retention.ComplianceFlags)

	// Target conversation for compaction
	convID := os.Getenv("TARGET_CONVERSATION_ID")
	if convID == "" {
		log.Fatal("TARGET_CONVERSATION_ID environment variable is required")
	}

	startTime := time.Now()

	// Step 2: Fetch and normalize
	payload, err := FetchAndNormalizeConversation(context.Background(), convAPI, convID)
	if err != nil {
		log.Fatalf("Conversation fetch/normalization failed: %v", err)
	}

	// Step 3: Apply shrink directive via atomic PATCH
	err = ApplyShrinkDirective(context.Background(), convAPI, payload, retention)
	if err != nil {
		log.Fatalf("Shrink directive PATCH failed: %v", err)
	}

	latency := time.Since(startTime).Milliseconds()

	// Step 4: Audit and webhook sync
	audit := &CompactionAudit{
		Timestamp:      time.Now().UTC(),
		ConversationID: convID,
		LatencyMs:      float64(latency),
	}

	err = SyncExternalArchive(context.Background(), payload, audit)
	if err != nil {
		log.Fatalf("Archive synchronization failed: %v", err)
	}

	slog.Info("compaction pipeline complete", "conversation_id", convID, "latency_ms", audit.LatencyMs, "status", audit.Status)
}

Common Errors & Debugging

Error: 401 Unauthorized or 403 Forbidden

  • What causes it: The OAuth token expired, the client credentials are incorrect, or the application lacks the required scopes.
  • How to fix it: Verify GENESYS_CLIENT_ID and GENESYS_CLIENT_SECRET in your environment. Ensure the OAuth token request includes conversations:view and conversations:update. The SDK caches tokens automatically, but manual refresh is required if the token expires during long-running batch jobs.
  • Code showing the fix:
if httpResp.StatusCode == 401 || httpResp.StatusCode == 403 {
	slog.Error("authentication failure detected, refreshing token", "status", httpResp.StatusCode)
	// Re-initialize auth or trigger SDK token refresh
}

Error: 429 Too Many Requests

  • What causes it: Genesys Cloud enforces rate limits per tenant and per endpoint. Rapid compaction loops trigger throttling.
  • How to fix it: Implement exponential backoff with jitter. The complete example includes a retry loop that delays requests on 429 responses. Adjust RetryWaitMin and RetryMax based on your tenant tier limits.
  • Code showing the fix:
if httpResp.StatusCode == 429 {
	retryAfter := httpResp.Header.Get("Retry-After")
	if retryAfter == "" {
		retryAfter = "2"
	}
	slog.Warn("rate limited, applying backoff", "retry_after", retryAfter)
	time.Sleep(2 * time.Second)
	continue
}

Error: 400 Bad Request during PATCH

  • What causes it: The update payload contains invalid fields, missing required attributes, or violates conversation-constraints.
  • How to fix it: Validate the ConversationUpdate struct before sending. Ensure wrapupCode values match your organization wrap-up codes. Check that the conversation is not currently active, as active conversations reject metadata updates.
  • Code showing the fix:
if resp.State != nil && *resp.State == "active" {
	return fmt.Errorf("cannot compact active conversation %s: wait for wrapup", convID)
}
