Querying and Managing Genesys Cloud Interaction Archives with Go

What You Will Build

• A Go service that queries the Genesys Cloud Archiving API for interaction records within specific date ranges and filters.
• The code parses raw interaction payloads to extract transcripts and metadata, validates data integrity via checksums, and compresses records for local storage.
• This tutorial covers Go 1.21+ with the official Genesys Cloud Platform Client SDK and standard library utilities.

Prerequisites

• OAuth2 Client Credentials flow with scopes: analytics:query, conversation:view
• Genesys Cloud Platform Client Go SDK (github.com/MyPureCloud/platform-client-v2-go)
• Go 1.21 or later runtime
• External dependencies: golang.org/x/oauth2, golang.org/x/oauth2/clientcredentials

Authentication Setup

Genesys Cloud requires OAuth2 bearer tokens for all API calls. The Client Credentials flow is standard for server-to-server integrations. The following code initializes an OAuth2 config and demonstrates token caching logic to avoid unnecessary credential exchanges.

package main

import (
	"context"
	"fmt"
	"time"

	"golang.org/x/oauth2"
	"golang.org/x/oauth2/clientcredentials"
)

type OAuthConfig struct {
	ClientID     string
	ClientSecret string
	BaseURL      string
}

func NewOAuthClient(cfg OAuthConfig) *oauth2.Config {
	return &clientcredentials.Config{
		ClientID:     cfg.ClientID,
		ClientSecret: cfg.ClientSecret,
		TokenURL:     fmt.Sprintf("%s/oauth/token", cfg.BaseURL),
	}
}

func GetCachedToken(ctx context.Context, cfg *oauth2.Config, cacheFile string) (*oauth2.Token, error) {
	// In production, implement file or Redis-based token caching here.
	// This example fetches a fresh token. Caching requires checking expiration
	// and refreshing only when expiring within a 60-second window.
	token, err := cfg.Token(ctx)
	if err != nil {
		return nil, fmt.Errorf("oauth token retrieval failed: %w", err)
	}
	if !token.Valid() {
		return nil, fmt.Errorf("oauth token invalid")
	}
	return token, nil
}

The TokenURL endpoint is /oauth/token. The SDK handles token injection automatically when you pass an http.Client with an oauth2 transport. You must request the analytics:query scope during client registration in the Genesys Cloud admin console.

Implementation

Step 1: Initialize SDK and Query Archiving API with Pagination

The Archiving API endpoint /api/v2/analytics/conversations/details/query returns conversation records. The request body requires dateFrom, dateTo, size, and optional filter expressions. The response contains a nextPage token for pagination.

package main

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

	"github.com/MyPureCloud/platform-client-v2-go/go-rest/v2/rest"
	"github.com/MyPureCloud/platform-client-v2-go/genesyscloud"
	"github.com/MyPureCloud/platform-client-v2-go/genesyscloud/conversationv2"
	"golang.org/x/oauth2"
)

type ArchiveQueryParams struct {
	DateFrom time.Time
	DateTo   time.Time
	PageSize int
	Filter   string
}

func QueryArchivedInteractions(ctx context.Context, client *oauth2.Config, base string, params ArchiveQueryParams) ([]conversationv2.ConversationsDetailsQueryResponse, error) {
	oauthClient := &http.Client{
		Transport: &oauth2.Transport{
			Base:   http.DefaultTransport,
			Source: oauth2.ReuseTokenSource(nil, client.TokenSource(ctx)),
		},
	}

	config := rest.NewConfig(base)
	config.SetHttpClient(oauthClient)
	genesysClient, err := genesyscloud.NewClient(ctx, config)
	if err != nil {
		return nil, fmt.Errorf("sdk initialization failed: %w", err)
	}

	api := conversationv2.NewApiService(genesysClient)
	var allResults []conversationv2.ConversationsDetailsQueryResponse
	var nextPage *string

	for {
		body := conversationv2.ConversationsDetailsQueryRequest{
			DateFrom: &params.DateFrom,
			DateTo:   &params.DateTo,
			Size:     &params.PageSize,
			Filter:   &params.Filter,
			NextPage: nextPage,
		}

		resp, httpResp, err := api.PostAnalyticsConversationsDetailsQuery(ctx, body)
		if err != nil {
			if httpResp != nil {
				return nil, fmt.Errorf("api request failed: status %d, body: %s", httpResp.StatusCode, string(httpResp.Body))
			}
			return nil, fmt.Errorf("api request failed: %w", err)
		}

		if resp.Conversations != nil {
			allResults = append(allResults, *resp.Conversations...)
		}

		if resp.NextPage == nil || *resp.NextPage == "" {
			break
		}
		nextPage = resp.NextPage
	}

	return allResults, nil
}

The PostAnalyticsConversationsDetailsQuery method maps directly to the /api/v2/analytics/conversations/details/query endpoint. The size parameter controls page size (maximum 10000). The loop continues until nextPage is empty. You must handle 429 responses by implementing exponential backoff in production.

Step 2: Parse Payloads, Validate Checksums, and Compress Records

Archived interactions contain nested interactions arrays with transcripts, metadata, and media references. This step extracts the transcript, computes a SHA256 checksum for integrity verification, and writes the record to a GZIP-compressed file.

package main

import (
	"compress/gzip"
	"crypto/sha256"
	"encoding/json"
	"fmt"
	"os"
	"path/filepath"

	"github.com/MyPureCloud/platform-client-v2-go/genesyscloud/conversationv2"
)

type ExtractedRecord struct {
	InteractionID string `json:"interactionId"`
	Transcript    string `json:"transcript"`
	Metadata      map[string]interface{} `json:"metadata"`
	Checksum      string `json:"checksum"`
}

func ParseAndArchiveRecord(record conversationv2.ConversationsDetailsQueryResponse, outputDir string) (ExtractedRecord, error) {
	transcript := ""
	if record.Interactions != nil && len(*record.Interactions) > 0 {
		interaction := (*record.Interactions)[0]
		if interaction.Transcript != nil {
			transcript = *interaction.Transcript
		}
	}

	metadata := make(map[string]interface{})
	if record.Metadata != nil {
		for k, v := range *record.Metadata {
			metadata[k] = v
		}
	}

	rawData, err := json.Marshal(map[string]interface{}{
		"interactionId": record.Id,
		"transcript":    transcript,
		"metadata":      metadata,
	})
	if err != nil {
		return ExtractedRecord{}, fmt.Errorf("json marshal failed: %w", err)
	}

	checksum := fmt.Sprintf("%x", sha256.Sum256(rawData))

	filename := fmt.Sprintf("%s_%s.json.gz", record.Id, checksum[:8])
	filepath := filepath.Join(outputDir, filename)

	file, err := os.Create(filepath)
	if err != nil {
		return ExtractedRecord{}, fmt.Errorf("file creation failed: %w", err)
	}
	defer file.Close()

	gzWriter := gzip.NewWriter(file)
	_, err = gzWriter.Write(rawData)
	if err != nil {
		return ExtractedRecord{}, fmt.Errorf("gzip write failed: %w", err)
	}
	err = gzWriter.Close()
	if err != nil {
		return ExtractedRecord{}, fmt.Errorf("gzip close failed: %w", err)
	}

	return ExtractedRecord{
		InteractionID: *record.Id,
		Transcript:    transcript,
		Metadata:      metadata,
		Checksum:      checksum,
	}, nil
}

The sha256.Sum256 function generates a deterministic hash. The checksum prefix in the filename prevents accidental overwrites during re-queries. The gzip writer reduces storage footprint by approximately 70 percent for JSON payloads.

Step 3: Schedule Retention Cleanup and Generate Availability Reports

Data retention policies require periodic removal of expired local archives. This step implements a ticker-based cleanup job and generates a compliance-ready availability report.

package main

import (
	"encoding/json"
	"fmt"
	"io/fs"
	"os"
	"path/filepath"
	"time"
)

type ArchiveReport struct {
	GeneratedAt string               `json:"generatedAt"`
	TotalFiles  int                  `json:"totalFiles"`
	Records     []ArchiveReportEntry `json:"records"`
}

type ArchiveReportEntry struct {
	Filename string `json:"filename"`
	Size     int64  `json:"sizeBytes"`
	Modified time.Time `json:"lastModified"`
}

func GenerateAvailabilityReport(outputDir string) (ArchiveReport, error) {
	var entries []ArchiveReportEntry
	err := filepath.WalkDir(outputDir, func(path string, d fs.DirEntry, err error) error {
		if err != nil {
			return err
		}
		if d.IsDir() {
			return nil
		}
		info, err := d.Info()
		if err != nil {
			return err
		}
		entries = append(entries, ArchiveReportEntry{
			Filename: d.Name(),
			Size:     info.Size(),
			Modified: info.ModTime(),
		})
		return nil
	})
	if err != nil {
		return ArchiveReport{}, fmt.Errorf("directory walk failed: %w", err)
	}

	report := ArchiveReport{
		GeneratedAt: time.Now().UTC().Format(time.RFC3339),
		TotalFiles:  len(entries),
		Records:     entries,
	}

	return report, nil
}

func StartRetentionCleanup(outputDir string, retentionDays int) <-chan error {
	errChan := make(chan error, 1)
	go func() {
		ticker := time.NewTicker(24 * time.Hour)
		defer ticker.Stop()

		for range ticker.C {
			cutoff := time.Now().UTC().AddDate(0, 0, -retentionDays)
			matches, err := filepath.Glob(filepath.Join(outputDir, "*.json.gz"))
			if err != nil {
				errChan <- fmt.Errorf("glob failed: %w", err)
				continue
			}

			for _, match := range matches {
				info, err := os.Stat(match)
				if err != nil {
					continue
				}
				if info.ModTime().Before(cutoff) {
					if err := os.Remove(match); err != nil {
						errChan <- fmt.Errorf("cleanup failed for %s: %w", match, err)
					}
				}
			}
		}
	}()
	return errChan
}

The StartRetentionCleanup function runs asynchronously. It evaluates file modification times against a configurable retentionDays threshold. The GenerateAvailabilityReport function walks the output directory and returns a structured JSON report suitable for compliance audits.

Step 4: Expose Archive Search API for Retrieval Tools

External systems need a local endpoint to query archived records without hitting Genesys Cloud directly. This step builds an HTTP server that searches compressed archives and returns matching transcripts.

package main

import (
	"compress/gzip"
	"encoding/json"
	"fmt"
	"io"
	"net/http"
	"os"
	"path/filepath"
	"strings"
)

func StartArchiveSearchServer(outputDir string, port string) error {
	http.HandleFunc("/api/v1/archive/search", func(w http.ResponseWriter, r *http.Request) {
		if r.Method != http.MethodGet {
			http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
			return
		}

		query := r.URL.Query().Get("q")
		if query == "" {
			http.Error(w, "Missing query parameter 'q'", http.StatusBadRequest)
			return
		}

		var results []ExtractedRecord
		matches, err := filepath.Glob(filepath.Join(outputDir, "*.json.gz"))
		if err != nil {
			http.Error(w, "Archive directory unreadable", http.StatusInternalServerError)
			return
		}

		for _, match := range matches {
			file, err := os.Open(match)
			if err != nil {
				continue
			}

			gzReader, err := gzip.NewReader(file)
			if err != nil {
				file.Close()
				continue
			}

			data, err := io.ReadAll(gzReader)
			gzReader.Close()
			file.Close()
			if err != nil {
				continue
			}

			var record ExtractedRecord
			if err := json.Unmarshal(data, &record); err != nil {
				continue
			}

			if strings.Contains(strings.ToLower(record.Transcript), strings.ToLower(query)) {
				results = append(results, record)
			}
		}

		w.Header().Set("Content-Type", "application/json")
		if err := json.NewEncoder(w).Encode(results); err != nil {
			http.Error(w, "JSON encoding failed", http.StatusInternalServerError)
		}
	})

	addr := fmt.Sprintf(":%s", port)
	fmt.Printf("Archive search server listening on %s\n", addr)
	return http.ListenAndServe(addr, nil)
}

The /api/v1/archive/search?q=term endpoint decompresses files in memory, unmarshals JSON, and performs case-insensitive transcript matching. For production deployments, replace in-memory decompression with a database index to avoid blocking the HTTP goroutine.

package main

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

	"github.com/MyPureCloud/platform-client-v2-go/genesyscloud/conversationv2"
	"golang.org/x/oauth2"
	"golang.org/x/oauth2/clientcredentials"
)

func main() {
	if len(os.Args) < 4 {
		log.Fatal("Usage: go run main.go <client_id> <client_secret> <base_url>")
	}

	clientID := os.Args[1]
	clientSecret := os.Args[2]
	baseURL := os.Args[3]

	ctx := context.Background()
	oauthCfg := &clientcredentials.Config{
		ClientID:     clientID,
		ClientSecret: clientSecret,
		TokenURL:     fmt.Sprintf("%s/oauth/token", baseURL),
	}

	outputDir := "./archives"
	if err := os.MkdirAll(outputDir, 0755); err != nil {
		log.Fatalf("Failed to create output directory: %v", err)
	}

	params := ArchiveQueryParams{
		DateFrom: time.Now().UTC().AddDate(0, 0, -7),
		DateTo:   time.Now().UTC(),
		PageSize: 500,
		Filter:   "type eq 'voice'",
	}

	records, err := QueryArchivedInteractions(ctx, oauthCfg, baseURL, params)
	if err != nil {
		log.Fatalf("Query failed: %v", err)
	}

	fmt.Printf("Retrieved %d interaction records\n", len(records))

	for _, record := range records {
		_, err := ParseAndArchiveRecord(record, outputDir)
		if err != nil {
			log.Printf("Failed to archive record %s: %v", *record.Id, err)
		}
	}

	report, err := GenerateAvailabilityReport(outputDir)
	if err != nil {
		log.Fatalf("Report generation failed: %v", err)
	}

	reportJSON, _ := json.MarshalIndent(report, "", "  ")
	fmt.Println(string(reportJSON))

	cleanupErrs := StartRetentionCleanup(outputDir, 30)
	go func() {
		for err := range cleanupErrs {
			log.Printf("Retention cleanup error: %v", err)
		}
	}()

	if err := StartArchiveSearchServer(outputDir, "8080"); err != nil {
		log.Fatalf("Server failed: %v", err)
	}
}

Run the program with go run main.go <CLIENT_ID> <CLIENT_SECRET> <BASE_URL>. Replace BASE_URL with your environment endpoint (e.g., https://api.mypurecloud.com). The service queries the last seven days of voice interactions, archives them, generates a compliance report, starts a 30-day retention cleaner, and exposes a search endpoint on port 8080.

Common Errors & Debugging

Error: 401 Unauthorized

• What causes it: The OAuth token is expired, malformed, or lacks the analytics:query scope.
• How to fix it: Verify the client credentials in the Genesys Cloud admin console. Ensure the token source refreshes automatically. Check the oauth2 transport configuration.
• Code showing the fix: Replace static token assignment with oauth2.ReuseTokenSource as shown in Step 1.

Error: 429 Too Many Requests

• What causes it: Pagination loops exceed the platform rate limit (typically 10 requests per second per client).
• How to fix it: Implement exponential backoff between nextPage iterations. Reduce pageSize if concurrent queries are high.
• Code showing the fix:

time.Sleep(time.Duration(100+backoff) * time.Millisecond)
backoff = backoff * 2

Error: 400 Bad Request (Invalid Filter)

• What causes it: The filter string contains unsupported syntax or invalid field names.
• How to fix it: Use the Genesys Cloud filter syntax reference. Valid operators include eq, neq, gt, lt, contains. Ensure field names match the schema (e.g., type, direction, startTime).
• Code showing the fix: Validate filter strings against a regex or use the SDK’s filter builder utilities before submission.

Error: Checksum Mismatch During Verification

• What causes it: File corruption during disk I/O or GZIP compression errors.
• How to fix it: Recompute the checksum on the decompressed payload and compare it to the stored hash. Delete and re-download the record if they differ.
• Code showing the fix: Add a verification step that reads the GZIP file, recomputes sha256.Sum256, and aborts processing if hashes diverge.
