Tag Genesys Cloud Interaction Recordings via REST API with Go

What You Will Build

• A Go service that programmatically applies classification labels and retention directives to recording metadata, validates taxonomy compliance, tracks index update latency, and generates audit logs for governance.
• This implementation uses the Genesys Cloud CX REST API and the official platform-client-sdk-go library.
• The tutorial covers Go 1.21+ with production-grade error handling, retry logic, and compliance synchronization.

Prerequisites

• OAuth client credentials (confidential) registered in Genesys Cloud with the following scopes: recording:write, tagging:write, analytics:report:read
• Genesys Cloud API version: v2
• Go runtime: 1.21 or later
• External dependencies: github.com/genesyscloud/platform-client-sdk-go/v2/platformclientv2, github.com/google/uuid, github.com/pkg/errors, log/slog, time, context

Authentication Setup

Genesys Cloud requires OAuth 2.0 client credentials flow for server-to-server operations. The token must be cached and refreshed before expiration. The following code establishes a credential manager that handles token acquisition and automatic refresh.

package main

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

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

// OAuthConfig holds credentials and cache state
type OAuthConfig struct {
	ClientID     string
	ClientSecret string
	TenantDomain string
	Token        *oauth2.Token
	RefreshedAt  time.Time
}

// GetToken retrieves a fresh or cached OAuth token
func (o *OAuthConfig) GetToken(ctx context.Context) (*oauth2.Token, error) {
	if o.Token != nil && time.Since(o.RefreshedAt) < 50*time.Minute {
		return o.Token, nil
	}

	cfg := &clientcredentials.Config{
		ClientID:     o.ClientID,
		ClientSecret: o.ClientSecret,
		TokenURL:     fmt.Sprintf("https://%s/oauth/token", o.TenantDomain),
		Scopes:       []string{"recording:write", "tagging:write", "analytics:report:read"},
	}

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

	o.Token = token
	o.RefreshedAt = time.Now()
	slog.Info("oauth token acquired", "expires_in", token.Expiry)
	return token, nil
}

The token cache prevents unnecessary network calls. The client credentials flow does not require a redirect URI. The scopes listed grant write access to recording metadata and tagging operations.

Implementation

Step 1: Initialize SDK and Validate Tagging Payload Schema

The Genesys Cloud media archive enforces strict constraints. A single recording supports a maximum of 100 tags. Labels must reference valid taxonomy identifiers, and duplicate labels within the same taxonomy are rejected at the API level. The validation pipeline checks these constraints before network transmission.

package main

import (
	"fmt"
	"log/slog"
	"slices"

	"github.com/genesyscloud/platform-client-sdk-go/v2/platformclientv2"
)

const MaxTagCount = 100

// TagRequest represents a single label assignment
type TagRequest struct {
	Label      string
	TaxonomyID string
	Confidence float32
	Status     string
}

// ValidateTags checks taxonomy compliance, duplicate labels, and maximum count limits
func ValidateTags(tags []TagRequest) error {
	if len(tags) == 0 {
		return fmt.Errorf("tag array cannot be empty")
	}
	if len(tags) > MaxTagCount {
		return fmt.Errorf("tag count %d exceeds maximum limit %d", len(tags), MaxTagCount)
	}

	seenLabels := make(map[string]bool)
	for i, tag := range tags {
		if tag.Label == "" || tag.TaxonomyID == "" {
			return fmt.Errorf("tag at index %d missing label or taxonomyId", i)
		}
		key := fmt.Sprintf("%s:%s", tag.TaxonomyID, tag.Label)
		if seenLabels[key] {
			return fmt.Errorf("duplicate label detected: %s in taxonomy %s", tag.Label, tag.TaxonomyID)
		}
		seenLabels[key] = true

		if tag.Confidence < 0.0 || tag.Confidence > 1.0 {
			return fmt.Errorf("confidence value must be between 0.0 and 1.0, got %f", tag.Confidence)
		}
		if !slices.Contains([]string{"Active", "Pending", "Rejected"}, tag.Status) {
			return fmt.Errorf("invalid status: %s. Must be Active, Pending, or Rejected", tag.Status)
		}
	}
	return nil
}

The validation function enforces format verification before payload construction. The API rejects payloads with missing taxonomy identifiers or confidence values outside the 0.0 to 1.0 range. Duplicate detection prevents classification drift during batch operations.

Step 2: Construct Atomic Tagging Request and Execute POST

Genesys Cloud uses atomic POST operations for tagging. The endpoint POST /api/v2/recordings/medias/{mediaId}/tags accepts a MediaTaggingRequest object. The request body includes the tag array and optional retention policy directives. The SDK handles serialization, but you must implement retry logic for 429 rate limits.

Raw HTTP cycle reference:

POST /api/v2/recordings/medias/{mediaId}/tags HTTP/1.1
Host: api.mypurecloud.com
Authorization: Bearer <access_token>
Content-Type: application/json
Accept: application/json

{
  "tags": [
    {
      "label": "Compliance:PCI-DSS",
      "taxonomyId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
      "confidence": 0.95,
      "status": "Active"
    }
  ],
  "retentionPolicy": {
    "name": "Standard 365 Day",
    "id": "ret-policy-9876"
  }
}

HTTP/1.1 200 OK
Content-Type: application/json

{
  "mediaId": "rec-12345678-abcd-efgh-ijkl-123456789012",
  "tags": [
    {
      "id": "tag-001",
      "label": "Compliance:PCI-DSS",
      "taxonomyId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
      "confidence": 0.95,
      "status": "Active",
      "createdTimestamp": "2024-01-15T10:30:00.000Z"
    }
  ],
  "retentionPolicy": {
    "id": "ret-policy-9876",
    "name": "Standard 365 Day"
  },
  "indexUpdateStatus": "Pending",
  "links": {}
}

Go SDK implementation with retry logic and latency tracking:

package main

import (
	"context"
	"fmt"
	"log/slog"
	"math"
	"net/http"
	"time"

	"github.com/genesyscloud/platform-client-sdk-go/v2/platformclientv2"
	"github.com/pkg/errors"
)

// TaggingResult captures operation metrics
type TaggingResult struct {
	MediaID          string
	TagsApplied      int
	LatencyMs        float64
	IndexUpdateRate  string
	ErrorCode        string
	ErrorMessage     string
}

// PostTagsWithRetry executes the tagging request with exponential backoff
func PostTagsWithRetry(
	ctx context.Context,
	apiClient *platformclientv2.ApiClient,
	mediaID string,
	request platformclientv2.MediaTaggingRequest,
) (*TaggingResult, error) {
	startTime := time.Now()
	api := platformclientv2.NewTaggingApi(apiClient)

	maxRetries := 3
	var lastErr error

	for attempt := 0; attempt <= maxRetries; attempt++ {
		resp, httpResp, err := api.PostRecordingsMediasMediaIdTags(ctx, mediaID, request)
		if err != nil {
			lastErr = err
			if httpResp != nil && httpResp.StatusCode == http.StatusTooManyRequests {
				backoff := time.Duration(math.Pow(2, float64(attempt))) * time.Second
				slog.Warn("rate limit 429 encountered, retrying", "attempt", attempt, "backoff", backoff)
				time.Sleep(backoff)
				continue
			}
			return nil, errors.Wrap(err, "tagging API call failed")
		}

		latency := time.Since(startTime).Seconds() * 1000
		result := &TaggingResult{
			MediaID:         mediaID,
			TagsApplied:     len(resp.GetTags()),
			LatencyMs:       latency,
			IndexUpdateRate: resp.GetIndexUpdateStatus(),
		}

		slog.Info("tagging completed", "media_id", mediaID, "tags", len(resp.GetTags()), "latency_ms", latency)
		return result, nil
	}

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

The PostRecordingsMediasMediaIdTags method performs the atomic operation. The SDK returns a MediaTaggingResponse object containing the applied tags and index update status. The retry loop handles 429 responses automatically. Latency tracking measures the full request cycle including retries.

Step 3: Process Index Updates, Track Latency, and Trigger Compliance Callbacks

Tagging operations trigger automatic index updates in the Genesys Cloud media archive. You must synchronize these events with external compliance databases. The following code defines a callback handler interface, generates audit logs, and tracks index update rates for archive efficiency monitoring.

package main

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

// ComplianceCallback defines the synchronization contract
type ComplianceCallback interface {
	SyncTaggingEvent(ctx context.Context, result *TaggingResult) error
}

// AuditLogger records governance events
type AuditLogger struct {
	Logger *slog.Logger
}

func (a *AuditLogger) LogTaggingEvent(ctx context.Context, result *TaggingResult) {
	a.Logger.InfoContext(ctx, "tagging_audit",
		"media_id", result.MediaID,
		"tags_applied", result.TagsApplied,
		"latency_ms", result.LatencyMs,
		"index_status", result.IndexUpdateRate,
		"timestamp", time.Now().UTC().Format(time.RFC3339),
	)
}

// RecordingTagger exposes the automated interaction management interface
type RecordingTagger struct {
	ApiClient     *platformclientv2.ApiClient
	Callback      ComplianceCallback
	Audit         *AuditLogger
}

// TagRecording orchestrates validation, execution, callback sync, and audit logging
func (t *RecordingTagger) TagRecording(ctx context.Context, mediaID string, tags []TagRequest, retentionName string) error {
	if err := ValidateTags(tags); err != nil {
		return fmt.Errorf("validation failed: %w", err)
	}

	apiTags := make([]platformclientv2.Mediatag, len(tags))
	for i, t := range tags {
		apiTags[i] = platformclientv2.Mediatag{
			Label:      &t.Label,
			TaxonomyId: &t.TaxonomyID,
			Confidence: &t.Confidence,
			Status:     &t.Status,
		}
	}

	retentionPolicy := platformclientv2.Retentionpolicy{
		Name: &retentionName,
	}

	request := platformclientv2.MediaTaggingRequest{
		Tags:            apiTags,
		RetentionPolicy: &retentionPolicy,
	}

	result, err := PostTagsWithRetry(ctx, t.ApiClient, mediaID, request)
	if err != nil {
		t.Audit.Logger.ErrorContext(ctx, "tagging_failed", "error", err)
		return err
	}

	t.Audit.LogTaggingEvent(ctx, result)

	if t.Callback != nil {
		if err := t.Callback.SyncTaggingEvent(ctx, result); err != nil {
			slog.Error("compliance callback failed", "error", err)
		}
	}

	return nil
}

The RecordingTagger struct encapsulates the full lifecycle. The TagRecording method runs validation, constructs the payload, executes the atomic POST, logs the audit trail, and invokes the compliance callback. Index update rates are captured from the response and logged for archive efficiency monitoring.

Complete Working Example

The following module combines authentication, validation, tagging execution, and audit logging into a single runnable service. Replace the placeholder credentials and taxonomy identifiers before execution.

package main

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

	"github.com/genesyscloud/platform-client-sdk-go/v2/platformclientv2"
)

// MockComplianceDB implements ComplianceCallback for demonstration
type MockComplianceDB struct{}

func (m *MockComplianceDB) SyncTaggingEvent(ctx context.Context, result *TaggingResult) error {
	slog.InfoContext(ctx, "compliance_db_sync", "media_id", result.MediaID, "status", "success")
	return nil
}

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

	// 1. Authentication
	oauth := &OAuthConfig{
		ClientID:     os.Getenv("GENESYS_CLIENT_ID"),
		ClientSecret: os.Getenv("GENESYS_CLIENT_SECRET"),
		TenantDomain: os.Getenv("GENESYS_TENANT_DOMAIN"),
	}

	ctx := context.Background()
	token, err := oauth.GetToken(ctx)
	if err != nil {
		slog.Error("authentication failed", "error", err)
		os.Exit(1)
	}

	// 2. SDK Initialization
	config := platformclientv2.NewConfiguration()
	config.SetBasePath(fmt.Sprintf("https://%s", os.Getenv("GENESYS_TENANT_DOMAIN")))
	apiClient, err := platformclientv2.NewApiClient(config)
	if err != nil {
		slog.Error("sdk initialization failed", "error", err)
		os.Exit(1)
	}
	apiClient.SetAuth("oauth2", token.AccessToken)

	// 3. Tagger Configuration
	tagger := &RecordingTagger{
		ApiClient: apiClient,
		Callback:  &MockComplianceDB{},
		Audit:     &AuditLogger{Logger: slog.Default()},
	}

	// 4. Tagging Payload
	tags := []TagRequest{
		{
			Label:      "Compliance:PCI-DSS",
			TaxonomyID: "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
			Confidence: 0.95,
			Status:     "Active",
		},
		{
			Label:      "Quality:Pass",
			TaxonomyID: "b2c3d4e5-f6a7-8901-bcde-f12345678901",
			Confidence: 0.88,
			Status:     "Active",
		},
	}

	mediaID := "rec-12345678-abcd-efgh-ijkl-123456789012"
	retentionName := "Standard 365 Day"

	// 5. Execute Tagging
	err = tagger.TagRecording(ctx, mediaID, tags, retentionName)
	if err != nil {
		slog.Error("tagging operation failed", "error", err)
		os.Exit(1)
	}

	slog.Info("recording tagged successfully", "media_id", mediaID)
}

The complete example demonstrates credential loading, SDK configuration, callback registration, and synchronous tagging execution. The service exits cleanly on validation or API failures. Environment variables store sensitive credentials.

Common Errors & Debugging

Error: 400 Bad Request

• Cause: Payload violates schema constraints. Common triggers include exceeding the 100 tag limit, missing taxonomy identifiers, or duplicate labels within the same taxonomy.
• Fix: Verify the ValidateTags function output. Ensure each tag references a published taxonomy in Genesys Cloud. Reduce batch size to 50 tags during initial testing.
• Code Fix: The validation pipeline catches these before network transmission. Review the error message for the exact field violation.

Error: 401 Unauthorized / 403 Forbidden

• Cause: Expired OAuth token or missing scopes. The tagging endpoint requires recording:write and tagging:write.
• Fix: Regenerate the token using oauth.GetToken(ctx). Verify the application role in Genesys Cloud includes the Recording Administrator or Tagging Administrator permissions.
• Code Fix: The GetToken method implements automatic refresh. If 401 persists, check the client credentials against the Genesys Cloud admin console.

Error: 429 Too Many Requests

• Cause: Rate limit cascade across microservices. Genesys Cloud enforces per-tenant and per-endpoint request quotas.
• Fix: The PostTagsWithRetry function implements exponential backoff. Increase the maxRetries value if operating at scale. Implement request queuing in the caller.
• Code Fix: The retry loop sleeps for 2^attempt seconds. Monitor the Retry-After header in production deployments.

Error: 500 Internal Server Error / 503 Service Unavailable

• Cause: Media archive index synchronization delay or backend maintenance.
• Fix: Wait 30 seconds and retry. The indexUpdateStatus field in the response indicates Pending or Completed. Do not overwrite tags during Pending states.
• Code Fix: The retry logic handles 5xx responses if you extend the status code check. Implement idempotency keys for large-scale batch jobs.
