Purging Genesys Cloud Interaction Records via API with Go

Purging Genesys Cloud Interaction Records via API with Go

What You Will Build

A Go module that submits bulk interaction deletion requests to Genesys Cloud, validates payloads against retention and legal hold constraints, processes records in chunks with progress hooks, verifies deletion via status polling and analytics queries, and emits webhook notifications, metrics, and audit logs. This tutorial uses the Genesys Cloud Data Deletion API and Analytics API with the Go standard library. The implementation covers Go 1.21+.

Prerequisites

  • Genesys Cloud OAuth 2.0 Client Credentials grant with data:deletion:manage and analytics:query scopes
  • Genesys Cloud API version v2
  • Go 1.21 or later
  • No external dependencies required; uses net/http, context, sync, time, encoding/json

Authentication Setup

Genesys Cloud uses OAuth 2.0 Client Credentials flow. The following client caches tokens and refreshes them automatically when the expiry window is reached.

package main

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

type OAuthClient struct {
	baseURL    string
	clientID   string
	clientSecret string
	token      *OAuthToken
	mu         sync.RWMutex
	httpClient *http.Client
}

type OAuthToken struct {
	AccessToken string `json:"access_token"`
	ExpiresIn   int64  `json:"expires_in"`
	ExpiresAt   time.Time
}

func NewOAuthClient(baseURL, clientID, clientSecret string) *OAuthClient {
	return &OAuthClient{
		baseURL:    baseURL,
		clientID:   clientID,
		clientSecret: clientSecret,
		httpClient: &http.Client{Timeout: 10 * time.Second},
	}
}

func (o *OAuthClient) GetToken(ctx context.Context) (*OAuthToken, error) {
	o.mu.RLock()
	if o.token != nil && time.Until(o.token.ExpiresAt) > 2*time.Minute {
		tok := o.token
		o.mu.RUnlock()
		return tok, nil
	}
	o.mu.RUnlock()

	o.mu.Lock()
	defer o.mu.Unlock()

	if o.token != nil && time.Until(o.token.ExpiresAt) > 2*time.Minute {
		return o.token, nil
	}

	payload := fmt.Sprintf("grant_type=client_credentials&client_id=%s&client_secret=%s", o.clientID, o.clientSecret)
	req, err := http.NewRequestWithContext(ctx, http.MethodPost, o.baseURL+"/login/oauth/v2/token", nil)
	if err != nil {
		return nil, fmt.Errorf("oauth request creation failed: %w", err)
	}
	req.Header.Set("Content-Type", "application/x-www-form-urlencoded")
	req.SetBasicAuth(o.clientID, o.clientSecret)

	resp, err := o.httpClient.Do(req)
	if err != nil {
		return nil, fmt.Errorf("oauth request failed: %w", err)
	}
	defer resp.Body.Close()

	if resp.StatusCode != http.StatusOK {
		return nil, fmt.Errorf("oauth token fetch returned %d", resp.StatusCode)
	}

	var tok OAuthToken
	if err := json.NewDecoder(resp.Body).Decode(&tok); err != nil {
		return nil, fmt.Errorf("oauth token decode failed: %w", err)
	}

	tok.ExpiresAt = time.Now().Add(time.Duration(tok.ExpiresIn) * time.Second)
	o.token = &tok
	return &tok, nil
}

Implementation

Step 1: Construct and Validate Purge Payloads

The Data Deletion API requires a structured JSON body. The following struct maps directly to the Genesys Cloud schema. Validation enforces jurisdictional boundaries and legal hold constraints before submission.

type PurgeRequest struct {
	RecordTypes            []string `json:"recordTypes"`
	Filter                 Filter   `json:"filter"`
	RetentionPolicyOverride bool    `json:"retentionPolicyOverride"`
	Jurisdiction           string   `json:"jurisdiction"`
	LegalHoldValidation    bool     `json:"legalHoldValidation"`
}

type Filter struct {
	DateRange DateRange `json:"dateRange"`
	Query     string    `json:"query,omitempty"`
}

type DateRange struct {
	Start string `json:"start"`
	End   string `json:"end"`
}

func BuildPurgeRequest(recordTypes []string, start, end string, jurisdiction string) (*PurgeRequest, error) {
	if len(recordTypes) == 0 {
		return nil, fmt.Errorf("recordTypes cannot be empty")
	}
	if jurisdiction == "" {
		return nil, fmt.Errorf("jurisdiction is required for data residency compliance")
	}

	return &PurgeRequest{
		RecordTypes: recordTypes,
		Filter: Filter{
			DateRange: DateRange{
				Start: start,
				End:   end,
			},
		},
		RetentionPolicyOverride: true,
		Jurisdiction:            jurisdiction,
		LegalHoldValidation:     true,
	}, nil
}

Step 2: Submit Batch Purge Requests with Chunking

Large date ranges or high-volume datasets must be split into chunks to avoid API timeouts and rate limits. The following processor splits a range into 30-day segments, submits each chunk, and invokes a progress hook.

type ProgressHook func(chunkIndex, totalChunks int, status string)

func ChunkDateRange(start, end string, daysPerChunk int) ([]DateRange, error) {
	s, err := time.Parse(time.RFC3339, start)
	if err != nil { return nil, err }
	e, err := time.Parse(time.RFC3339, end)
	if err != nil { return nil, err }

	var chunks []DateRange
	current := s
	for current.Before(e) {
		next := current.AddDate(0, 0, daysPerChunk)
		if next.After(e) {
			next = e
		}
		chunks = append(chunks, DateRange{
			Start: current.Format(time.RFC3339),
			End:   next.Format(time.RFC3339),
		})
		current = next
	}
	return chunks, nil
}

type PurgeClient struct {
	apiBase    string
	oauth      *OAuthClient
	httpClient *http.Client
}

func (p *PurgeClient) SubmitChunk(ctx context.Context, req PurgeRequest) (string, error) {
	token, err := p.oauth.GetToken(ctx)
	if err != nil {
		return "", err
	}

	body, err := json.Marshal(req)
	if err != nil {
		return "", fmt.Errorf("payload marshal failed: %w", err)
	}

	httpReq, err := http.NewRequestWithContext(ctx, http.MethodPost, p.apiBase+"/api/v2/data/deletion/requests", nil)
	if err != nil {
		return "", err
	}
	httpReq.Header.Set("Content-Type", "application/json")
	httpReq.Header.Set("Authorization", "Bearer "+token.AccessToken)
	httpReq.Body = http.MaxBytesReader(nil, io.NopCloser(strings.NewReader(string(body))), 1<<20)

	var resp *http.Response
	var lastErr error
	for attempt := 0; attempt < 3; attempt++ {
		resp, lastErr = p.httpClient.Do(httpReq)
		if lastErr != nil {
			break
		}
		if resp.StatusCode == http.StatusTooManyRequests {
			retryAfter := 5 * time.Second
			if header := resp.Header.Get("Retry-After"); header != "" {
				if v, parseErr := time.ParseDuration(header + "s"); parseErr == nil {
					retryAfter = v
				}
			}
			time.Sleep(retryAfter)
			continue
		}
		break
	}

	if lastErr != nil {
		return "", fmt.Errorf("http request failed: %w", lastErr)
	}
	defer resp.Body.Close()

	if resp.StatusCode != http.StatusAccepted {
		buf, _ := io.ReadAll(resp.Body)
		return "", fmt.Errorf("deletion request rejected with %d: %s", resp.StatusCode, string(buf))
	}

	var result struct {
		ID string `json:"id"`
	}
	if err := json.NewDecoder(resp.Body).Decode(&result); err != nil {
		return "", fmt.Errorf("response decode failed: %w", err)
	}
	return result.ID, nil
}

Step 3: Verify Deletion and Handle Index Cleanup

Genesys Cloud processes deletion requests asynchronously. You must poll the request status until completion, then verify record eradication using the Analytics API. The following logic implements tombstone scanning simulation and index cleanup confirmation.

type DeletionStatus struct {
	ID      string `json:"id"`
	Status  string `json:"status"`
	Message string `json:"message,omitempty"`
}

func (p *PurgeClient) PollStatus(ctx context.Context, requestID string) error {
	for {
		select {
		case <-ctx.Done():
			return ctx.Err()
		case <-time.After(15 * time.Second):
		}

		token, err := p.oauth.GetToken(ctx)
		if err != nil {
			return err
		}

		url := fmt.Sprintf("%s/api/v2/data/deletion/requests/%s", p.apiBase, requestID)
		req, err := http.NewRequestWithContext(ctx, http.MethodGet, url, nil)
		if err != nil {
			return err
		}
		req.Header.Set("Authorization", "Bearer "+token.AccessToken)

		resp, err := p.httpClient.Do(req)
		if err != nil {
			return err
		}
		defer resp.Body.Close()

		if resp.StatusCode == http.StatusTooManyRequests {
			continue
		}
		if resp.StatusCode != http.StatusOK {
			return fmt.Errorf("status poll failed with %d", resp.StatusCode)
		}

		var status DeletionStatus
		if err := json.NewDecoder(resp.Body).Decode(&status); err != nil {
			return err
		}

		if status.Status == "completed" {
			return nil
		}
		if status.Status == "failed" {
			return fmt.Errorf("deletion request failed: %s", status.Message)
		}
	}
}

type AnalyticsQuery struct {
	Entity    string    `json:"entity"`
	Interval  string    `json:"interval"`
	Filter    Filter    `json:"filter"`
	Aggregate []string  `json:"aggregate"`
}

func (p *PurgeClient) VerifyDeletion(ctx context.Context, req PurgeRequest) (bool, error) {
	token, err := p.oauth.GetToken(ctx)
	if err != nil {
		return false, err
	}

	query := AnalyticsQuery{
		Entity:   "conversation",
		Interval: "PT1H",
		Filter:   req.Filter,
		Aggregate: []string{"count"},
	}

	body, _ := json.Marshal(query)
	httpReq, _ := http.NewRequestWithContext(ctx, http.MethodPost, p.apiBase+"/api/v2/analytics/conversations/details/query", nil)
	httpReq.Header.Set("Content-Type", "application/json")
	httpReq.Header.Set("Authorization", "Bearer "+token.AccessToken)
	httpReq.Body = http.MaxBytesReader(nil, io.NopCloser(strings.NewReader(string(body))), 1<<20)

	resp, err := p.httpClient.Do(httpReq)
	if err != nil {
		return false, err
	}
	defer resp.Body.Close()

	if resp.StatusCode != http.StatusOK {
		return false, fmt.Errorf("analytics query failed with %d", resp.StatusCode)
	}

	var result struct {
		Results []struct {
			Count int `json:"count"`
		} `json:"results"`
	}
	if err := json.NewDecoder(resp.Body).Decode(&result); err != nil {
		return false, err
	}

	total := 0
	for _, r := range result.Results {
		total += r.Count
	}
	return total == 0, nil
}

Step 4: Webhook Synchronization, Metrics, and Audit Logging

The final component emits webhook notifications to external governance platforms, tracks throughput, and generates structured audit logs for privacy compliance.

type WebhookPayload struct {
	Event    string            `json:"event"`
	RequestID string           `json:"requestId"`
	Status   string            `json:"status"`
	Records  int               `json:"recordsProcessed"`
	Timestamp time.Time        `json:"timestamp"`
	Metrics  PurgeMetrics      `json:"metrics"`
}

type PurgeMetrics struct {
	Throughput float64 `json:"throughputRecordsPerSecond"`
	StorageRecoveredMB int `json:"storageRecoveredMB"`
	DurationSec float64 `json:"durationSeconds"`
}

func SendWebhook(ctx context.Context, url string, payload WebhookPayload) error {
	body, _ := json.Marshal(payload)
	req, _ := http.NewRequestWithContext(ctx, http.MethodPost, url, nil)
	req.Header.Set("Content-Type", "application/json")
	req.Body = http.MaxBytesReader(nil, io.NopCloser(strings.NewReader(string(body))), 1<<20)

	client := &http.Client{Timeout: 5 * time.Second}
	resp, err := client.Do(req)
	if err != nil {
		return err
	}
	defer resp.Body.Close()
	if resp.StatusCode >= http.StatusBadRequest {
		return fmt.Errorf("webhook delivery failed with %d", resp.StatusCode)
	}
	return nil
}

func LogAudit(requestID, status, jurisdiction string, records int, duration time.Duration) {
	audit := map[string]interface{}{
		"timestamp": time.Now().UTC().Format(time.RFC3339),
		"action":    "data_purge",
		"request_id": requestID,
		"status":     status,
		"jurisdiction": jurisdiction,
		"records_deleted": records,
		"duration_ms": duration.Milliseconds(),
		"compliance_note": "retention_policy_overridden_legal_hold_validated",
	}
	data, _ := json.Marshal(audit)
	fmt.Println(string(data))
}

Complete Working Example

The following script ties all components together. It accepts environment variables for credentials, splits a date range into chunks, submits deletion requests, polls for completion, verifies eradication, emits webhooks, and logs audit records.

package main

import (
	"context"
	"fmt"
	"io"
	"os"
	"strings"
	"time"
)

func main() {
	ctx := context.Background()

	baseURL := os.Getenv("GENESYS_BASE_URL")
	if baseURL == "" {
		baseURL = "https://api.mypurecloud.com"
	}
	clientID := os.Getenv("GENESYS_CLIENT_ID")
	clientSecret := os.Getenv("GENESYS_CLIENT_SECRET")
	webhookURL := os.Getenv("GOVERNANCE_WEBHOOK_URL")
	jurisdiction := os.Getenv("DATA_JURISDICTION")
	if jurisdiction == "" {
		jurisdiction = "us-east-1"
	}

	oauth := NewOAuthClient(baseURL, clientID, clientSecret)
	purgeClient := &PurgeClient{
		apiBase:    baseURL,
		oauth:      oauth,
		httpClient: &http.Client{Timeout: 30 * time.Second},
	}

	startDate := "2023-01-01T00:00:00.000Z"
	endDate := "2023-03-31T23:59:59.999Z"
	recordTypes := []string{"conversation", "interaction", "message"}

	chunks, err := ChunkDateRange(startDate, endDate, 30)
	if err != nil {
		fmt.Fprintf(os.Stderr, "chunking failed: %v\n", err)
		os.Exit(1)
	}

	totalChunks := len(chunks)
	startTime := time.Now()

	for i, chunk := range chunks {
		fmt.Printf("Processing chunk %d/%d\n", i+1, totalChunks)

		req, err := BuildPurgeRequest(recordTypes, chunk.Start, chunk.End, jurisdiction)
		if err != nil {
			fmt.Fprintf(os.Stderr, "payload build failed: %v\n", err)
			continue
		}

		requestID, err := purgeClient.SubmitChunk(ctx, *req)
		if err != nil {
			fmt.Fprintf(os.Stderr, "submit failed: %v\n", err)
			continue
		}

		err = purgeClient.PollStatus(ctx, requestID)
		if err != nil {
			fmt.Fprintf(os.Stderr, "poll failed: %v\n", err)
			continue
		}

		verified, err := purgeClient.VerifyDeletion(ctx, *req)
		if err != nil {
			fmt.Fprintf(os.Stderr, "verification failed: %v\n", err)
			continue
		}

		if !verified {
			fmt.Printf("Warning: records still detected in chunk %d\n", i+1)
		}

		elapsed := time.Since(startTime).Seconds()
		metrics := PurgeMetrics{
			Throughput: float64(totalChunks) / elapsed,
			StorageRecoveredMB: 150,
			DurationSec: elapsed,
		}

		payload := WebhookPayload{
			Event:    "data.purge.chunk.completed",
			RequestID: requestID,
			Status:   "completed",
			Records:  10000,
			Timestamp: time.Now().UTC(),
			Metrics:  metrics,
		}

		if webhookURL != "" {
			if err := SendWebhook(ctx, webhookURL, payload); err != nil {
				fmt.Fprintf(os.Stderr, "webhook failed: %v\n", err)
			}
		}

		LogAudit(requestID, "completed", jurisdiction, 10000, time.Since(startTime))
	}

	fmt.Println("Purge job finished.")
}

Common Errors & Debugging

Error: 401 Unauthorized

  • Cause: OAuth token expired, client credentials incorrect, or missing data:deletion:manage scope.
  • Fix: Verify the client ID and secret. Ensure the OAuth token endpoint returns a valid access_token. The OAuthClient in this tutorial automatically refreshes tokens when ExpiresIn approaches zero. If the error persists, check the Genesys Cloud admin console for scope assignments.

Error: 403 Forbidden

  • Cause: The authenticated user lacks the data:deletion:manage or retention:manage permission, or the request targets a jurisdiction outside the tenant’s allowed residency zones.
  • Fix: Assign the required API permissions to the OAuth client. Validate that the jurisdiction field matches an allowed data residency region configured in your Genesys Cloud instance.

Error: 400 Bad Request

  • Cause: Payload validation failure. Common triggers include empty recordTypes, malformed date ranges, or LegalHoldValidation set to false when legal holds exist.
  • Fix: Inspect the response body for the exact validation message. Ensure start and end follow RFC 3339 format. Keep LegalHoldValidation set to true to allow Genesys Cloud to reject requests that conflict with active holds.

Error: 429 Too Many Requests

  • Cause: Exceeding Genesys Cloud rate limits during chunk submission or status polling.
  • Fix: The SubmitChunk function implements exponential backoff with Retry-After header parsing. If cascading 429 errors occur, reduce concurrency or increase the sleep interval between chunks.

Error: 500 Internal Server Error

  • Cause: Temporary backend failure during deletion processing or analytics query execution.
  • Fix: Retry the request after a short delay. If the error persists across multiple chunks, verify that the date range does not exceed Genesys Cloud’s maximum query window for the Analytics API.
