Configuring Genesys Cloud Agent Assist Rules via REST API with Go

What You Will Build

• A Go module that constructs, validates, and atomically deploys Agent Assist rule configurations to Genesys Cloud CX while tracking commit latency, generating audit logs, and synchronizing events with external workflow engines.
• This tutorial uses the Genesys Cloud Agent Assist Rules API (/api/v2/agent-assist/rules) with direct HTTP transport for full request visibility.
• The implementation is written in Go 1.21+ using standard library packages and production-ready error handling patterns.

Prerequisites

• OAuth client credentials with agent-assist:rules:read and agent-assist:rules:write scopes
• Genesys Cloud organization domain (e.g., acme.mypurecloud.com)
• Go 1.21 or higher
• External dependencies: none (standard library only)
• Environment variables: GENESYS_ORG_DOMAIN, GENESYS_CLIENT_ID, GENESYS_CLIENT_SECRET

Authentication Setup

Genesys Cloud uses OAuth 2.0 client credentials flow for server-to-server integrations. The token endpoint returns a JWT that expires after 600 seconds. You must cache the token and refresh it before expiration to avoid 401 Unauthorized responses.

package auth

import (
	"bytes"
	"encoding/base64"
	"encoding/json"
	"fmt"
	"io"
	"net/http"
	"time"
)

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

func FetchToken(orgDomain, clientID, clientSecret, scope string) (*OAuthResponse, error) {
	url := fmt.Sprintf("https://%s/oauth/token", orgDomain)
	payload := fmt.Sprintf("grant_type=client_credentials&scope=%s", scope)

	req, err := http.NewRequest("POST", url, bytes.NewBufferString(payload))
	if err != nil {
		return nil, fmt.Errorf("failed to create auth request: %w", err)
	}

	auth := base64.StdEncoding.EncodeToString([]byte(fmt.Sprintf("%s:%s", clientID, clientSecret)))
	req.Header.Set("Authorization", "Basic "+auth)
	req.Header.Set("Content-Type", "application/x-www-form-urlencoded")

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

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

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

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

The FetchToken function returns a structured response with a calculated expiration time. Your application must check ExpiresAt before each API call and refresh the token when necessary.

Implementation

Step 1: Payload Construction and Schema Validation

Agent Assist rules require strict schema compliance. The API rejects payloads with invalid condition operators, unsupported action types, or missing required fields. You must validate the configuration before transmission to prevent 400 Bad Request responses and wasted API quota.

package agentassist

import (
	"encoding/json"
	"fmt"
	"time"
)

type RuleCondition struct {
	Field    string `json:"field"`
	Operator string `json:"operator"`
	Value    string `json:"value"`
}

type RuleAction struct {
	Type   string                 `json:"type"`
	Config map[string]interface{} `json:"config"`
}

type AgentAssistRule struct {
	Id              string          `json:"id,omitempty"`
	Name            string          `json:"name"`
	Description     string          `json:"description"`
	Enabled         bool            `json:"enabled"`
	Priority        int             `json:"priority"`
	MatchConditions []RuleCondition `json:"matchConditions"`
	Actions         []RuleAction    `json:"actions"`
	Version         int             `json:"version,omitempty"`
}

// ValidateRule checks schema constraints before API submission
func ValidateRule(rule AgentAssistRule, maxRules int, currentRuleCount int) error {
	if currentRuleCount >= maxRules {
		return fmt.Errorf("maximum rule count (%d) reached", maxRules)
	}

	if rule.Name == "" {
		return fmt.Errorf("rule name cannot be empty")
	}

	validOperators := map[string]bool{
		"eq": true, "neq": true, "contains": true,
		"startsWith": true, "endsWith": true, "regex": true,
	}

	for _, cond := range rule.MatchConditions {
		if cond.Field == "" {
			return fmt.Errorf("condition field cannot be empty")
		}
		if !validOperators[cond.Operator] {
			return fmt.Errorf("invalid condition operator: %s", cond.Operator)
		}
		if cond.Value == "" {
			return fmt.Errorf("condition value cannot be empty for operator %s", cond.Operator)
		}
	}

	validActions := map[string]bool{
		"showInsight": true, "playAudio": true,
		"showForm": true, "showSuggestion": true,
	}

	for _, act := range rule.Actions {
		if !validActions[act.Type] {
			return fmt.Errorf("unsupported action type: %s", act.Type)
		}
		if act.Type == "playAudio" {
			if _, exists := act.Config["audioUri"]; !exists {
				return fmt.Errorf("playAudio action requires audioUri in config")
			}
		}
	}

	return nil
}

The validation pipeline enforces operator allowlists, action compatibility, and organizational limits. Genesys Cloud defaults to 1000 rules per organization. You should enforce a lower threshold in production to reserve capacity for runtime scaling.

Step 2: Atomic PUT Operations with Retry Logic

Rule updates require atomic PUT requests to /api/v2/agent-assist/rules/{ruleId}. The API returns 429 Too Many Requests when rate limits are exceeded. You must implement exponential backoff with jitter to avoid cascading failures across microservices.

package agentassist

import (
	"bytes"
	"encoding/json"
	"fmt"
	"io"
	"math"
	"math/rand"
	"net/http"
	"time"
)

type ConfigClient struct {
	httpClient *http.Client
	baseURL    string
	token      string
}

func NewConfigClient(orgDomain string, token string) *ConfigClient {
	return &ConfigClient{
		httpClient: &http.Client{Timeout: 30 * time.Second},
		baseURL:    fmt.Sprintf("https://%s/api/v2", orgDomain),
		token:      token,
	}
}

func (c *ConfigClient) UpdateRule(rule AgentAssistRule) (*http.Response, []byte, error) {
	payload, err := json.Marshal(rule)
	if err != nil {
		return nil, nil, fmt.Errorf("failed to marshal rule: %w", err)
	}

	url := fmt.Sprintf("%s/agent-assist/rules/%s", c.baseURL, rule.Id)

	for attempt := 0; attempt < 5; attempt++ {
		req, err := http.NewRequest("PUT", url, bytes.NewBuffer(payload))
		if err != nil {
			return nil, nil, fmt.Errorf("failed to create request: %w", err)
		}

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

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

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

		if resp.StatusCode == http.StatusTooManyRequests {
			backoff := time.Duration(math.Pow(2, float64(attempt))) * time.Second
			jitter := time.Duration(rand.Intn(1000)) * time.Millisecond
			time.Sleep(backoff + jitter)
			continue
		}

		if resp.StatusCode >= 400 {
			return resp, body, fmt.Errorf("api error %d: %s", resp.StatusCode, string(body))
		}

		return resp, body, nil
	}

	return nil, nil, fmt.Errorf("max retry attempts exceeded for rule %s", rule.Id)
}

The PUT operation triggers automatic index rebuilds in Genesys Cloud. The platform queues the rule for inference runtime compilation and propagates changes to edge nodes within 15 to 30 seconds. You do not need to call separate indexing endpoints.

Step 3: Metrics, Audit Logging, and Callback Synchronization

Production deployments require observability. You must track commit latency, success rates, and generate structured audit logs for compliance. Callback handlers synchronize configuration events with external workflow engines.

package agentassist

import (
	"encoding/json"
	"fmt"
	"log"
	"sync/atomic"
	"time"
)

type ConfigEvent struct {
	Timestamp  time.Time `json:"timestamp"`
	RuleId     string    `json:"ruleId"`
	RuleName   string    `json:"ruleName"`
	Action     string    `json:"action"`
	LatencyMs  float64   `json:"latencyMs"`
	StatusCode int       `json:"statusCode"`
	Success    bool      `json:"success"`
}

type RuleConfigurer struct {
	client      *ConfigClient
	successRate atomic.Int64
	totalCalls  atomic.Int64
	callback    func(event ConfigEvent)
}

func NewRuleConfigurer(client *ConfigClient, onEvent func(event ConfigEvent)) *RuleConfigurer {
	return &RuleConfigurer{
		client:   client,
		callback: onEvent,
	}
}

func (rc *RuleConfigurer) DeployRule(rule AgentAssistRule) error {
	start := time.Now()
	rc.totalCalls.Add(1)

	resp, body, err := rc.client.UpdateRule(rule)
	latency := time.Since(start).Milliseconds()

	event := ConfigEvent{
		Timestamp: time.Now().UTC(),
		RuleId:    rule.Id,
		RuleName:  rule.Name,
		Action:    "PUT",
		LatencyMs: float64(latency),
		StatusCode: 0,
		Success:    false,
	}

	if resp != nil {
		event.StatusCode = resp.StatusCode
	}

	if err == nil && resp != nil && resp.StatusCode == http.StatusOK {
		rc.successRate.Add(1)
		event.Success = true
	}

	rc.callback(event)
	rc.logAudit(event)

	if err != nil {
		return fmt.Errorf("deployment failed for rule %s: %w", rule.Name, err)
	}

	return nil
}

func (rc *RuleConfigurer) logAudit(event ConfigEvent) {
	logBytes, _ := json.Marshal(event)
	log.Printf("AUDIT: %s", string(logBytes))
}

func (rc *RuleConfigurer) GetCommitMetrics() (float64, int64) {
	total := rc.totalCalls.Load()
	success := rc.successRate.Load()
	if total == 0 {
		return 0, 0
	}
	rate := float64(success) / float64(total) * 100
	return rate, total
}

The RuleConfigurer struct encapsulates deployment logic, metrics tracking, and audit generation. The callback channel delivers events to external systems without blocking the main execution thread.

Complete Working Example

The following module combines authentication, validation, deployment, and observability into a single runnable script. Replace environment variables with your Genesys Cloud credentials.

package main

import (
	"encoding/base64"
	"fmt"
	"log"
	"os"
	"time"

	"agentassist"
	"auth"
)

func main() {
	orgDomain := os.Getenv("GENESYS_ORG_DOMAIN")
	clientID := os.Getenv("GENESYS_CLIENT_ID")
	clientSecret := os.Getenv("GENESYS_CLIENT_SECRET")

	if orgDomain == "" || clientID == "" || clientSecret == "" {
		log.Fatal("missing required environment variables")
	}

	token, err := auth.FetchToken(orgDomain, clientID, clientSecret, "agent-assist:rules:read agent-assist:rules:write")
	if err != nil {
		log.Fatalf("authentication failed: %v", err)
	}

	configClient := agentassist.NewConfigClient(orgDomain, token.AccessToken)

	configurer := agentassist.NewRuleConfigurer(configClient, func(event agentassist.ConfigEvent) {
		fmt.Printf("[WORKFLOW SYNC] Rule %s deployed: success=%t latency=%vms\n",
			event.RuleName, event.Success, event.LatencyMs)
	})

	rule := agentassist.AgentAssistRule{
		Id:          "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
		Name:        "Insurance Quote Trigger",
		Description: "Displays compliance insight when customer mentions premium",
		Enabled:     true,
		Priority:    10,
		MatchConditions: []agentassist.RuleCondition{
			{Field: "transcript", Operator: "contains", Value: "premium"},
			{Field: "intent", Operator: "eq", Value: "quote_request"},
		},
		Actions: []agentassist.RuleAction{
			{Type: "showInsight", Config: map[string]interface{}{
				"insightId": "compliance-check-v2",
				"position":  "sidebar",
			}},
		},
	}

	if err := agentassist.ValidateRule(rule, 500, 42); err != nil {
		log.Fatalf("validation failed: %v", err)
	}

	if err := configurer.DeployRule(rule); err != nil {
		log.Fatalf("deployment failed: %v", err)
	}

	rate, total := configurer.GetCommitMetrics()
	fmt.Printf("Commit success rate: %.2f%% (%d total calls)\n", rate, total)
}

Run the script with go run main.go. The module validates the payload, transmits the atomic PUT request, handles rate limiting, and emits audit logs to stdout.

Common Errors & Debugging

Error: 400 Bad Request

• What causes it: Invalid JSON schema, unsupported condition operators, or missing required action configuration fields.
• How to fix it: Run the payload through ValidateRule before submission. Verify that matchConditions use allowed operators and actions include required config keys.
• Code showing the fix: The validation function checks operator allowlists and action compatibility before HTTP transmission.

Error: 401 Unauthorized

• What causes it: Expired JWT token or missing agent-assist:rules:write scope.
• How to fix it: Refresh the token when time.Now().After(token.ExpiresAt) evaluates to true. Ensure the OAuth client has both read and write scopes for Agent Assist rules.
• Code showing the fix: Check token.ExpiresAt before each request cycle and call auth.FetchToken to retrieve a fresh credential.

Error: 403 Forbidden

• What causes it: OAuth client lacks organization-level permissions or the user associated with the service account is restricted from Agent Assist configuration.
• How to fix it: Grant the service account the Agent Assist Admin role in the Genesys Cloud admin console. Verify the OAuth client is bound to an active user.

Error: 429 Too Many Requests

• What causes it: Exceeding Genesys Cloud rate limits (typically 200 requests per minute per organization for configuration endpoints).
• How to fix it: Implement exponential backoff with jitter. The UpdateRule method retries up to 5 times with increasing delays.
• Code showing the fix: The retry loop calculates backoff = 2^attempt * 1s and adds random jitter to prevent thundering herd scenarios.

Error: 409 Conflict

• What causes it: Version mismatch during concurrent edits. Genesys Cloud uses optimistic locking on rule resources.
• How to fix it: Fetch the latest rule version with GET /api/v2/agent-assist/rules/{id} before modifying. Increment the Version field in your payload to match the server state.
