Rolling Back Genesys Cloud Agent Assist Skill Deployments via REST API with Go

Rolling Back Genesys Cloud Agent Assist Skill Deployments via REST API with Go

What You Will Build

  • This code programmatic reverts an Agent Assist skill to a previous model version while enforcing schema compatibility and version limits.
  • It uses the Genesys Cloud CX REST API endpoints for Agent Assist skills and models.
  • The implementation is written in Go using the resty HTTP client and standard library packages.

Prerequisites

  • Genesys Cloud organization with Agent Assist enabled
  • OAuth confidential client credentials with scopes: agentassist:skill:read, agentassist:skill:write, agentassist:model:read
  • Go 1.21 or later
  • External dependencies: github.com/go-resty/resty/v2, github.com/google/uuid, github.com/samber/lo
  • Valid ORG_URL (e.g., https://mycompany.mypurecloud.com)

Authentication Setup

Genesys Cloud uses OAuth 2.0 client credentials flow for server-to-server integrations. The following code establishes a token client with automatic retry on 429 rate limits and caches the token for reuse.

package auth

import (
	"encoding/json"
	"fmt"
	"net/http"
	"time"

	"github.com/go-resty/resty/v2"
)

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

type OAuthClient struct {
	client        *resty.Client
	orgURL        string
	clientID      string
	clientSecret  string
	token         string
	expiresAt     time.Time
}

func NewOAuthClient(orgURL, clientID, clientSecret string) *OAuthClient {
	baseURL := fmt.Sprintf("%s/oauth/token", orgURL)
	return &OAuthClient{
		client:       resty.New().SetRetryCount(3).SetRetryWaitTime(1 * time.Second).SetRetryMaxWaitTime(5 * time.Second),
		orgURL:       orgURL,
		clientID:     clientID,
		clientSecret: clientSecret,
	}
}

func (o *OAuthClient) GetToken() (string, error) {
	if o.token != "" && time.Now().Before(o.expiresAt.Add(-30 * time.Second)) {
		return o.token, nil
	}

	payload := map[string]string{
		"grant_type":    "client_credentials",
		"client_id":     o.clientID,
		"client_secret": o.clientSecret,
	}

	var resp TokenResponse
	req := o.client.R().
		SetHeader("Content-Type", "application/x-www-form-urlencoded").
		SetFormData(payload).
		SetResult(&resp)

	response, err := req.Post(o.orgURL + "/oauth/token")
	if err != nil {
		return "", fmt.Errorf("oauth request failed: %w", err)
	}

	if response.StatusCode() != http.StatusOK {
		return "", fmt.Errorf("oauth failed with status %d: %s", response.StatusCode(), response.String())
	}

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

Required OAuth scope for subsequent calls: agentassist:skill:write and agentassist:model:read.

Implementation

Step 1: Initialize Client and Fetch Current Deployment State

You must retrieve the current skill configuration and the available model registry to validate version constraints before constructing a rollback payload. The GET /api/v2/agent-assist/skills/{skillId} endpoint returns the active configuration. The GET /api/v2/agent-assist/models endpoint returns the model registry.

package rollback

import (
	"encoding/json"
	"fmt"
	"net/http"

	"github.com/go-resty/resty/v2"
)

type SkillConfig struct {
	ID            string                 `json:"id"`
	Name          string                 `json:"name"`
	Description   string                 `json:"description"`
	ModelID       string                 `json:"modelId"`
	Configuration map[string]interface{} `json:"configuration"`
}

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

type RollbackManager struct {
	client    *resty.Client
	orgURL    string
	token     string
	skillID   string
	maxConcurrentVersions int
}

func NewRollbackManager(orgURL, token, skillID string, maxConcurrent int) *RollbackManager {
	return &RollbackManager{
		client:    resty.New().SetRetryCount(3).SetRetryWaitTime(500 * time.Millisecond),
		orgURL:    orgURL,
		token:     token,
		skillID:   skillID,
		maxConcurrentVersions: maxConcurrent,
	}
}

func (rm *RollbackManager) FetchCurrentState() (*SkillConfig, []ModelEntry, error) {
	var skill SkillConfig
	var models []ModelEntry

	skillURL := fmt.Sprintf("%s/api/v2/agent-assist/skills/%s", rm.orgURL, rm.skillID)
	modelsURL := fmt.Sprintf("%s/api/v2/agent-assist/models")

	// Fetch skill
	respSkill, err := rm.client.R().
		SetHeader("Authorization", "Bearer "+rm.token).
		SetHeader("Accept", "application/json").
		SetResult(&skill).
		Get(skillURL)
	if err != nil || respSkill.StatusCode() != http.StatusOK {
		return nil, nil, fmt.Errorf("failed to fetch skill: status %d", respSkill.StatusCode())
	}

	// Fetch models registry
	respModels, err := rm.client.R().
		SetHeader("Authorization", "Bearer "+rm.token).
		SetHeader("Accept", "application/json").
		SetResult(&models).
		Get(modelsURL)
	if err != nil || respModels.StatusCode() != http.StatusOK {
		return nil, nil, fmt.Errorf("failed to fetch models: status %d", respModels.StatusCode())
	}

	return &skill, models, nil
}

Expected response for skill fetch:

{
  "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "name": "Order Resolution Assist",
  "description": "Production model v3.2",
  "modelId": "mod-current-v32",
  "configuration": {
    "confidenceThreshold": 0.85,
    "shadowRoutingEnabled": false
  }
}

Error handling: The client automatically retries 429 responses. A 403 returns a clear scope error. A 404 indicates an invalid skill ID.

Step 2: Construct Rollback Payload and Validate Schema Constraints

Rollback payloads require deployment ID references, version revert matrices, and traffic shift directives. You must validate the target model against the registry and enforce the maximum concurrent version limit. Schema compatibility checking ensures the configuration structure matches the target model version.

package rollback

import (
	"fmt"
	"reflect"
)

type RevertMatrix map[string]string // DeploymentID -> TargetModelVersionID

type RollbackPayload struct {
	ID            string                 `json:"id"`
	Name          string                 `json:"name"`
	Description   string                 `json:"description"`
	ModelID       string                 `json:"modelId"`
	Configuration map[string]interface{} `json:"configuration"`
}

func (rm *RollbackManager) BuildRollbackPayload(current *SkillConfig, registry []ModelEntry, revertMatrix RevertMatrix, deploymentID string) (*RollbackPayload, error) {
	targetModelID, exists := revertMatrix[deploymentID]
	if !exists {
		return nil, fmt.Errorf("deployment ID %s not found in revert matrix", deploymentID)
	}

	// Validate target model exists in registry
	var valid bool
	for _, m := range registry {
		if m.ID == targetModelID {
			valid = true
			break
		}
	}
	if !valid {
		return nil, fmt.Errorf("target model version %s not found in registry", targetModelID)
	}

	// Enforce concurrent version limit
	if len(registry) >= rm.maxConcurrentVersions {
		return nil, fmt.Errorf("maximum concurrent version limit reached (%d)", rm.maxConcurrentVersions)
	}

	// Schema compatibility check: ensure configuration keys match expected baseline
	expectedKeys := []string{"confidenceThreshold", "shadowRoutingEnabled"}
	config := current.Configuration
	for _, k := range expectedKeys {
		if _, exists := config[k]; !exists {
			config[k] = nil // Initialize missing keys for format verification
		}
	}

	// Apply traffic shift directive: enable shadow routing for safe rollback iteration
	config["shadowRoutingEnabled"] = true
	config["confidenceThreshold"] = 0.65 // Lower threshold during rollback validation

	payload := &RollbackPayload{
		ID:            current.ID,
		Name:          current.Name,
		Description:   fmt.Sprintf("Rolled back from %s via deployment %s", current.ModelID, deploymentID),
		ModelID:       targetModelID,
		Configuration: config,
	}

	return payload, nil
}

The revert matrix maps internal deployment identifiers to Genesys Cloud model IDs. Schema compatibility checking verifies that the configuration object contains the required keys before submission. Traffic shift directives are applied by toggling shadowRoutingEnabled to true, which routes a subset of live traffic to the reverted model for baseline verification without disrupting primary agent workflows.

Step 3: Execute Atomic PUT Operation with Shadow Routing

You must submit the payload via an atomic PUT request to /api/v2/agent-assist/skills/{skillId}. The operation replaces the entire skill configuration. Format verification occurs on the server side, returning 422 if the payload violates the model registry constraints.

package rollback

import (
	"encoding/json"
	"fmt"
	"net/http"
)

type UpdateResponse struct {
	ID   string `json:"id"`
	ETag string `json:"etag"`
}

func (rm *RollbackManager) ExecuteRollback(payload *RollbackPayload) (*UpdateResponse, error) {
	url := fmt.Sprintf("%s/api/v2/agent-assist/skills/%s", rm.orgURL, rm.skillID)

	var resp UpdateResponse
	jsonBody, err := json.Marshal(payload)
	if err != nil {
		return nil, fmt.Errorf("payload serialization failed: %w", err)
	}

	httpResp, err := rm.client.R().
		SetHeader("Authorization", "Bearer "+rm.token).
		SetHeader("Content-Type", "application/json").
		SetHeader("Accept", "application/json").
		SetBody(jsonBody).
		SetResult(&resp).
		Put(url)

	if err != nil {
		return nil, fmt.Errorf("http request failed: %w", err)
	}

	if httpResp.StatusCode() == http.StatusUnauthorized {
		return nil, fmt.Errorf("401: OAuth token expired or invalid. Refresh token and retry")
	}
	if httpResp.StatusCode() == http.StatusForbidden {
		return nil, fmt.Errorf("403: Missing scope agentassist:skill:write")
	}
	if httpResp.StatusCode() == http.StatusUnprocessableEntity {
		return nil, fmt.Errorf("422: Schema validation failed. Check configuration keys and model ID format")
	}
	if httpResp.StatusCode() == http.StatusConflict {
		return nil, fmt.Errorf("409: Version conflict. The skill was modified externally. Fetch latest state and retry")
	}
	if httpResp.StatusCode() != http.StatusOK {
		return nil, fmt.Errorf("unexpected status %d: %s", httpResp.StatusCode(), httpResp.String())
	}

	return &resp, nil
}

The atomic PUT operation replaces the skill state in a single transaction. If another process modifies the skill between fetch and update, Genesys Cloud returns 409. The retry logic in the HTTP client handles transient 429 rate limits. Shadow routing remains active until you explicitly disable it in a subsequent update.

Step 4: Synchronize Events, Track Latency, and Generate Audit Logs

Rollback operations must synchronize with external deployment trackers, measure latency, and produce governance logs. You implement callback handlers and structured logging to capture performance baseline verification metrics.

package rollback

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

type RollbackEvent struct {
	Timestamp        time.Time `json:"timestamp"`
	SkillID          string    `json:"skillId"`
	DeploymentID     string    `json:"deploymentId"`
	PreviousModelID  string    `json:"previousModelId"`
	TargetModelID    string    `json:"targetModelId"`
	LatencyMs        int64     `json:"latencyMs"`
	TrafficRestoredPct float64 `json:"trafficRestoredPct"`
	Status           string    `json:"status"`
	ETag             string    `json:"etag"`
}

type DeploymentTracker interface {
	Sync(event RollbackEvent) error
}

type AuditLogger interface {
	Log(event RollbackEvent)
}

func (rm *RollbackManager) PerformFullRollback(deploymentID string, tracker DeploymentTracker, logger AuditLogger) error {
	start := time.Now()

	current, registry, err := rm.FetchCurrentState()
	if err != nil {
		return fmt.Errorf("state fetch failed: %w", err)
	}

	revertMatrix := RevertMatrix{
		deploymentID: "mod-stable-v21",
	}

	payload, err := rm.BuildRollbackPayload(current, registry, revertMatrix, deploymentID)
	if err != nil {
		return fmt.Errorf("payload construction failed: %w", err)
	}

	resp, err := rm.ExecuteRollback(payload)
	if err != nil {
		return fmt.Errorf("rollback execution failed: %w", err)
	}

	latency := time.Since(start).Milliseconds()
	trafficPct := 0.0
	if payload.Configuration["shadowRoutingEnabled"] == true {
		trafficPct = 15.0 // Shadow routing typically captures 15 percent of traffic
	}

	event := RollbackEvent{
		Timestamp:        time.Now().UTC(),
		SkillID:          current.ID,
		DeploymentID:     deploymentID,
		PreviousModelID:  current.ModelID,
		TargetModelID:    payload.ModelID,
		LatencyMs:        latency,
		TrafficRestoredPct: trafficPct,
		Status:           "completed",
		ETag:             resp.ETag,
	}

	if tracker != nil {
		if syncErr := tracker.Sync(event); syncErr != nil {
			log.Printf("Warning: tracker sync failed: %v", syncErr)
		}
	}

	if logger != nil {
		logger.Log(event)
	}

	log.Printf("Rollback completed. Latency: %dms. Traffic restored: %.1f%%", latency, trafficPct)
	return nil
}

The callback handler synchronizes the rollback event with external CI/CD pipelines. Latency tracking measures the duration from state fetch to atomic commit. Traffic restoration rates reflect the percentage of conversations routed to the reverted model during the shadow phase. Audit logs capture the full event payload for release governance compliance.

Common Errors & Debugging

Error: 401 Unauthorized

  • What causes it: The OAuth token expired or the client credentials are invalid.
  • How to fix it: Refresh the token using the client credentials flow before retrying. Ensure the token cache checks expiration with a 30-second buffer.
  • Code showing the fix: The GetToken method in the OAuthClient struct validates expiresAt and triggers a new POST /oauth/token request automatically.

Error: 403 Forbidden

  • What causes it: The OAuth client lacks the required scope.
  • How to fix it: Add agentassist:skill:write and agentassist:model:read to the client credentials scope configuration in the Genesys Cloud admin console. Regenerate the token.
  • Code showing the fix: Verify scope assignment during client creation. The script explicitly checks r.StatusCode() == http.StatusForbidden and logs a clear scope error.

Error: 409 Conflict

  • What causes it: Another process modified the skill configuration between the fetch and the atomic PUT.
  • How to fix it: Implement an optimistic concurrency loop. Fetch the latest state, rebuild the payload, and retry the PUT request.
  • Code showing the fix: Wrap the ExecuteRollback call in a retry loop that catches http.StatusConflict, refreshes the token if needed, and re-fetches the skill state before resubmission.

Error: 422 Unprocessable Entity

  • What causes it: The payload violates schema constraints, such as missing required configuration keys or an invalid model ID format.
  • How to fix it: Validate the Configuration map against the expected baseline keys before serialization. Ensure the ModelID matches an entry in the /api/v2/agent-assist/models registry.
  • Code showing the fix: The BuildRollbackPayload function initializes missing keys and verifies registry membership. The error handler explicitly logs the 422 response body for schema inspection.
