Filtering Genesys Cloud Architecture API Search Results with Go

What You Will Build

A Go service that queries the Genesys Cloud Architecture API, constructs and validates complex filter payloads, iterates through narrow refinements atomically, tracks latency and success metrics, writes audit logs, and synchronizes results with an external webhook index.
This tutorial uses the GET /api/v2/architecture/search endpoint and the Client Credentials OAuth flow.
The implementation uses Go 1.21+ with the standard library for HTTP, JSON parsing, context management, and concurrency control.

Prerequisites

• Genesys Cloud OAuth 2.0 Client ID and Client Secret
• Required scope: architecture:search:read
• Go 1.21 or later
• Standard library packages: net/http, encoding/json, context, time, log, fmt, strings, sync, errors
• Access to a Genesys Cloud organization with Architecture API enabled

Authentication Setup

Genesys Cloud uses the OAuth 2.0 Client Credentials grant for server-to-server integrations. You must cache the access token and handle expiration before issuing architecture queries.

package main

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

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

type OAuthClient struct {
	BaseURL     string
	ClientID    string
	ClientSecret string
	HTTPClient  *http.Client
}

func NewOAuthClient(baseURL, clientID, clientSecret string) *OAuthClient {
	return &OAuthClient{
		BaseURL:      strings.TrimRight(baseURL, "/"),
		ClientID:     clientID,
		ClientSecret: clientSecret,
		HTTPClient:   &http.Client{Timeout: 10 * time.Second},
	}
}

func (o *OAuthClient) FetchToken(ctx context.Context) (TokenResponse, error) {
	url := fmt.Sprintf("%s/login/oauth2/token", o.BaseURL)
	form := strings.NewReader("grant_type=client_credentials&scope=architecture:search:read")

	req, err := http.NewRequestWithContext(ctx, http.MethodPost, url, form)
	if err != nil {
		return TokenResponse{}, fmt.Errorf("failed to create token request: %w", err)
	}

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

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

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

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

	var token TokenResponse
	if err := json.Unmarshal(body, &token); err != nil {
		return TokenResponse{}, fmt.Errorf("failed to parse token response: %w", err)
	}

	return token, nil
}

The FetchToken method requests an access token with the architecture:search:read scope. You must implement token caching in production. The example below includes a simple in-memory cache with expiration tracking.

type TokenCache struct {
	mu        sync.Mutex
	token     TokenResponse
	expiresAt time.Time
}

func (c *TokenCache) GetOrRefresh(ctx context.Context, fetcher func(context.Context) (TokenResponse, error)) (string, error) {
	c.mu.Lock()
	defer c.mu.Unlock()

	if time.Now().Before(c.expiresAt.Add(-30 * time.Second)) {
		return c.token.AccessToken, nil
	}

	token, err := fetcher(ctx)
	if err != nil {
		return "", err
	}

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

Implementation

Step 1: Filter Payload Construction and Complexity Validation

The Architecture API accepts filter strings and narrow directives. You must validate filter complexity before sending requests to prevent 400 Bad Request responses caused by exceeding platform limits. Genesys Cloud enforces a maximum filter string length and limits nested logical operators.

type FilterPayload struct {
	SearchRef        string   `json:"search_ref"`
	ArchitectureMatrix []string `json:"architecture_matrix"`
	NarrowDirective  string   `json:"narrow_directive"`
	Query            string   `json:"query"`
	Scope            string   `json:"scope"`
}

const (
	MaxFilterClauses = 15
	MaxNestingDepth  = 3
	MaxPayloadSize   = 8192
)

func ValidateFilterComplexity(payload FilterPayload) error {
	if len(payload.Query) > MaxPayloadSize {
		return errors.New("filter query exceeds maximum payload size")
	}

	clauseCount := strings.Count(payload.Query, " AND ") + strings.Count(payload.Query, " OR ") + 1
	if clauseCount > MaxFilterClauses {
		return fmt.Errorf("filter complexity limit exceeded: %d clauses (max %d)", clauseCount, MaxFilterClauses)
	}

	nesting := strings.Count(payload.Query, "(")
	if nesting > MaxNestingDepth {
		return fmt.Errorf("scope boundary violation: nesting depth %d exceeds limit %d", nesting, MaxNestingDepth)
	}

	if payload.Scope != "organization" && payload.Scope != "group" && payload.Scope != "user" {
		return errors.New("invalid scope boundary: must be organization, group, or user")
	}

	return nil
}

This validation pipeline checks syntax boundaries, enforces maximum clause counts, and verifies scope boundaries. You must run this before every HTTP call. The architecture_matrix field maps to the type parameter in the actual API request, defining which resource categories (flows, IVRs, routing strategies) the search targets.

Step 2: Atomic GET Search and Narrow Iteration

The Architecture API returns paginated results with narrow refinement options. You must handle the nextPageToken for pagination and the narrow parameter for progressive filtering. Each request must be an atomic HTTP GET operation with format verification.

type SearchResult struct {
	Results       []ArchitectureResource `json:"results"`
	TotalCount    int                    `json:"totalCount"`
	NextPageToken string                 `json:"nextPageToken"`
	NarrowOptions []NarrowOption         `json:"narrowOptions"`
}

type ArchitectureResource struct {
	ID   string `json:"id"`
	Type string `json:"type"`
	Name string `json:"name"`
}

type NarrowOption struct {
	Key   string `json:"key"`
	Value string `json:"value"`
	Count int    `json:"count"`
}

func (c *ArchitectureClient) ExecuteAtomicSearch(ctx context.Context, payload FilterPayload, token string, offset int, narrow string) (SearchResult, error) {
	baseURL := fmt.Sprintf("%s/api/v2/architecture/search", c.BaseURL)
	query := url.Values{}
	query.Set("q", payload.Query)
	query.Set("type", strings.Join(payload.ArchitectureMatrix, ","))
	query.Set("scope", payload.Scope)
	query.Set("limit", "100")
	query.Set("offset", fmt.Sprintf("%d", offset))
	if narrow != "" {
		query.Set("narrow", narrow)
	}
	if payload.SearchRef != "" {
		query.Set("refId", payload.SearchRef)
	}

	fullURL := fmt.Sprintf("%s?%s", baseURL, query.Encode())

	req, err := http.NewRequestWithContext(ctx, http.MethodGet, fullURL, nil)
	if err != nil {
		return SearchResult{}, fmt.Errorf("failed to create search request: %w", err)
	}

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

	start := time.Now()
	resp, err := c.HTTPClient.Do(req)
	latency := time.Since(start)
	if err != nil {
		return SearchResult{}, fmt.Errorf("search request failed: %w", err)
	}
	defer resp.Body.Close()

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

	if resp.StatusCode == http.StatusTooManyRequests {
		return SearchResult{}, ErrRateLimited
	}
	if resp.StatusCode == http.StatusUnauthorized {
		return SearchResult{}, ErrTokenExpired
	}
	if resp.StatusCode == http.StatusForbidden {
		return SearchResult{}, fmt.Errorf("forbidden: insufficient architecture:search:read scope")
	}
	if resp.StatusCode == http.StatusBadRequest {
		return SearchResult{}, fmt.Errorf("filter syntax error: %s", string(body))
	}
	if resp.StatusCode != http.StatusOK {
		return SearchResult{}, fmt.Errorf("search failed %d: %s", resp.StatusCode, string(body))
	}

	var result SearchResult
	if err := json.Unmarshal(body, &result); err != nil {
		return SearchResult{}, fmt.Errorf("failed to parse search response: %w", err)
	}

	c.Metrics.RecordLatency(latency, resp.StatusCode == http.StatusOK)
	c.AuditLog.Write("search_executed", map[string]interface{}{
		"query": payload.Query,
		"scope": payload.Scope,
		"latency_ms": latency.Milliseconds(),
		"success": resp.StatusCode == http.StatusOK,
		"offset": offset,
	})

	return result, nil
}

The ExecuteAtomicSearch method constructs the HTTP GET request, applies the filter payload, measures latency, and writes an audit log entry. The response format verification ensures the JSON structure matches the expected schema before processing.

Step 3: Narrow Validation, Retry Logic, and Webhook Sync

You must implement retry logic for 429 responses and automatic narrow refinement triggers. When the API returns narrowOptions, you iterate through them to progressively filter results. Each successful narrow iteration syncs with an external webhook index.

var ErrRateLimited = errors.New("rate limited: 429")
var ErrTokenExpired = errors.New("unauthorized: 401")

func (c *ArchitectureClient) ExecuteWithRetry(ctx context.Context, payload FilterPayload, token string) (SearchResult, error) {
	var result SearchResult
	retryCount := 0
	maxRetries := 3

	for retryCount < maxRetries {
		result, err := c.ExecuteAtomicSearch(ctx, payload, token, 0, "")
		if err != nil {
			if err == ErrRateLimited {
				backoff := time.Duration(retryCount+1) * 2 * time.Second
				c.AuditLog.Write("rate_limit_retry", map[string]interface{}{
					"retry": retryCount,
					"backoff_ms": backoff.Milliseconds(),
				})
				select {
				case <-time.After(backoff):
					retryCount++
					continue
				case <-ctx.Done():
					return SearchResult{}, ctx.Err()
				}
			}
			return SearchResult{}, err
		}
		break
	}

	return result, nil
}

func (c *ArchitectureClient) IterateNarrowRefinements(ctx context.Context, payload FilterPayload, token string) ([]ArchitectureResource, error) {
	var allResults []ArchitectureResource
	initialResult, err := c.ExecuteWithRetry(ctx, payload, token)
	if err != nil {
		return nil, fmt.Errorf("initial search failed: %w", err)
	}

	allResults = append(allResults, initialResult.Results...)

	if len(initialResult.NarrowOptions) == 0 {
		return allResults, nil
	}

	for _, narrow := range initialResult.NarrowOptions {
		refinedPayload := payload
		refinedPayload.NarrowDirective = fmt.Sprintf("%s=%s", narrow.Key, narrow.Value)

		refinedResult, err := c.ExecuteWithRetry(ctx, refinedPayload, token)
		if err != nil {
			c.AuditLog.Write("narrow_refinement_failed", map[string]interface{}{
				"key": narrow.Key,
				"error": err.Error(),
			})
			continue
		}

		allResults = append(allResults, refinedResult.Results...)
		c.Metrics.IncrementNarrowSuccess()

		if err := c.SyncWebhook(ctx, refinedResult); err != nil {
			c.AuditLog.Write("webhook_sync_failed", map[string]interface{}{
				"narrow_key": narrow.Key,
				"error": err.Error(),
			})
		}
	}

	return allResults, nil
}

func (c *ArchitectureClient) SyncWebhook(ctx context.Context, result SearchResult) error {
	webhookPayload := map[string]interface{}{
		"event":       "architecture_search_refined",
		"timestamp":   time.Now().UTC().Format(time.RFC3339),
		"result_count": len(result.Results),
		"total_count":  result.TotalCount,
		"resources":    result.Results,
	}

	body, _ := json.Marshal(webhookPayload)
	req, err := http.NewRequestWithContext(ctx, http.MethodPost, c.WebhookURL, bytes.NewReader(body))
	if err != nil {
		return fmt.Errorf("webhook request creation failed: %w", err)
	}

	req.Header.Set("Content-Type", "application/json")
	req.Header.Set("X-Audit-Source", "architecture-filter-service")

	resp, err := c.HTTPClient.Do(req)
	if err != nil {
		return fmt.Errorf("webhook delivery failed: %w", err)
	}
	defer resp.Body.Close()

	if resp.StatusCode < 200 || resp.StatusCode >= 300 {
		return fmt.Errorf("webhook returned non-success status: %d", resp.StatusCode)
	}

	return nil
}

The retry logic implements exponential backoff for rate limits. The narrow iteration loop validates each refinement, tracks success rates, and triggers webhook synchronization. The audit logger records every filtering event for governance compliance.

Common Errors & Debugging

Error: 400 Bad Request (Filter Syntax Error)

• Cause: The filter query contains invalid logical operators, unsupported fields, or exceeds the maximum complexity limit.
• Fix: Run ValidateFilterComplexity before the HTTP call. Ensure all field names match the Architecture API schema. Remove nested parentheses beyond depth three.
• Code: The validation function checks clause counts and nesting depth. Adjust MaxFilterClauses if your organization uses custom limits.

Error: 401 Unauthorized (Token Expired)

• Cause: The OAuth access token has expired or the client credentials are invalid.
• Fix: Implement token caching with a refresh buffer. Revoke and regenerate credentials if the error persists. Verify the architecture:search:read scope is attached to the OAuth client in the Genesys Cloud admin console.
• Code: The TokenCache struct refreshes tokens thirty seconds before expiration. Ensure the cache is shared across all goroutines.

Error: 403 Forbidden (Scope Mismatch)

• Cause: The OAuth client lacks the architecture:search:read scope or the user role does not permit architecture queries.
• Fix: Navigate to the Genesys Cloud admin console, locate the OAuth client, and attach the required scope. Assign the Service Administrator or Developer role to the service account.
• Code: The HTTP handler explicitly checks for 403 and returns a descriptive error.

Error: 429 Too Many Requests

• Cause: The Architecture API enforces rate limits per tenant. Rapid narrow iteration triggers throttling.
• Fix: Implement exponential backoff. Limit concurrent requests. Batch narrow refinements instead of issuing parallel GET calls.
• Code: The ExecuteWithRetry function implements linear backoff with configurable maximum retries. Adjust maxRetries and backoff duration based on your tenant tier.
