Migrating Cognigy.AI Intent Version Snapshots via REST API with TypeScript

What You Will Build

• A TypeScript module that constructs, validates, and promotes Cognigy.AI intent version snapshots using atomic PUT operations, tracks deployment metrics, and triggers environment synchronization for automated CXone bot management.
• This implementation uses the Cognigy.AI REST API v3 and standard Node.js HTTP clients.
• The code is written in TypeScript with strict typing, Zod schema validation, and production-grade error handling.

Prerequisites

• Cognigy.AI API v3 access with a service account or OAuth2 client credentials
• Required OAuth scopes: intent:read, intent:write, deployment:manage, environment:sync, webhook:write
• Node.js 18 or higher with TypeScript 5+
• External dependencies: axios, zod, dotenv, uuid
• Environment variables: COGNIGY_BASE_URL, COGNIGY_CLIENT_ID, COGNIGY_CLIENT_SECRET, COGNIGY_TENANT_ID

Authentication Setup

Cognigy.AI uses a JWT-based authentication flow. The following code retrieves an access token using client credentials and implements automatic token caching with expiration tracking.

import axios, { AxiosInstance } from 'axios';
import * as dotenv from 'dotenv';
dotenv.config();

interface AuthResponse {
  accessToken: string;
  expiresIn: number;
  tokenType: string;
}

class CognigyAuthClient {
  private client: AxiosInstance;
  private token: string | null = null;
  private tokenExpiry: number = 0;

  constructor(baseURL: string, clientId: string, clientSecret: string) {
    this.client = axios.create({
      baseURL,
      timeout: 10000,
      headers: { 'Content-Type': 'application/json' }
    });
    this.clientId = clientId;
    this.clientSecret = clientSecret;
  }

  private clientId: string;
  private clientSecret: string;

  async getAccessToken(): Promise<string> {
    if (this.token && Date.now() < this.tokenExpiry) {
      return this.token;
    }

    try {
      const response = await this.client.post<AuthResponse>('/api/v3/auth/token', {
        grant_type: 'client_credentials',
        client_id: this.clientId,
        client_secret: this.clientSecret
      });

      this.token = response.data.accessToken;
      this.tokenExpiry = Date.now() + (response.data.expiresIn * 1000) - 60000; // 60s buffer
      return this.token;
    } catch (error) {
      if (axios.isAxiosError(error)) {
        throw new Error(`Authentication failed with status ${error.response?.status}: ${error.response?.data}`);
      }
      throw error;
    }
  }

  getAuthenticatedClient(): AxiosInstance {
    return axios.create({
      baseURL: this.client.defaults.baseURL,
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${this.token}`
      }
    });
  }
}

OAuth Scope: intent:read, intent:write, deployment:manage

The authentication client caches the token until sixty seconds before expiration. This prevents unnecessary token refresh calls during batch migration operations.

Implementation

Step 1: Initialize Migrator and Validate Version History Limits

Cognigy.AI enforces a maximum version history per intent. Exceeding this limit causes immediate migration failure. The following code retrieves existing versions and validates against the platform constraint before constructing the migration payload.

import { z } from 'zod';
import { v4 as uuidv4 } from 'uuid';

const MAX_VERSION_HISTORY = 50;
const VERSION_MATRIX_SCHEMA = z.record(z.string(), z.string());
const DEPLOY_DIRECTIVE_SCHEMA = z.object({
  environmentId: z.string().uuid(),
  forceSync: z.boolean(),
  rollbackOnFailure: z.boolean()
});

interface IntentMigratePayload {
  snapshotId: string;
  targetVersion: string;
  versionMatrix: Record<string, string>;
  deployDirective: { environmentId: string; forceSync: boolean; rollbackOnFailure: boolean };
}

class CognigyIntentMigrator {
  private apiClient: AxiosInstance;
  private metrics = {
    startTime: 0,
    endTime: 0,
    successCount: 0,
    failureCount: 0,
    latencyMs: 0
  };

  constructor(authClient: CognigyAuthClient) {
    this.apiClient = authClient.getAuthenticatedClient();
  }

  async validateVersionHistory(intentId: string): Promise<boolean> {
    try {
      const response = await this.apiClient.get(`/api/v3/intents/${intentId}/versions`, {
        params: { page: 1, pageSize: MAX_VERSION_HISTORY + 1 }
      });

      const versionCount = response.data.total || response.data.items?.length || 0;
      if (versionCount >= MAX_VERSION_HISTORY) {
        throw new Error(`Intent ${intentId} has reached maximum version history limit (${MAX_VERSION_HISTORY}). Purge older versions before migrating.`);
      }
      return true;
    } catch (error) {
      if (axios.isAxiosError(error) && error.response?.status === 429) {
        return this.handleRateLimit(error);
      }
      throw error;
    }
  }

  private async handleRateLimit(error: any): Promise<never> {
    const retryAfter = parseInt(error.response?.headers['retry-after'] || '5', 10);
    console.log(`Rate limited. Retrying after ${retryAfter} seconds...`);
    await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
    throw error; // Caller implements retry loop
  }
}

OAuth Scope: intent:read

The pagination parameter pageSize is set to fifty-one to detect limit breaches without retrieving unnecessary data. The handleRateLimit method extracts the Retry-After header and pauses execution. Production code should wrap this in an exponential backoff loop.

Step 2: Construct Migrate Payload and Validate Schema

The migration payload must contain snapshot references, a version matrix mapping entity dependencies, and a deploy directive. The following code validates the payload against Zod schemas and dialog engine constraints.

  async constructAndValidatePayload(
    snapshotId: string,
    targetVersion: string,
    versionMatrix: Record<string, string>,
    deployDirective: { environmentId: string; forceSync: boolean; rollbackOnFailure: boolean }
  ): Promise<IntentMigratePayload> {
    try {
      VERSION_MATRIX_SCHEMA.parse(versionMatrix);
      DEPLOY_DIRECTIVE_SCHEMA.parse(deployDirective);
    } catch (error) {
      if (error instanceof z.ZodError) {
        throw new Error(`Schema validation failed: ${error.errors.map(e => e.message).join(', ')}`);
      }
      throw error;
    }

    // Dialog engine constraint: version matrix must not contain circular references
    if (this.detectCircularDependencies(versionMatrix)) {
      throw new Error('Version matrix contains circular entity dependencies. Resolve conflicts before migration.');
    }

    return {
      snapshotId,
      targetVersion,
      versionMatrix,
      deployDirective
    };
  }

  private detectCircularDependencies(matrix: Record<string, string>): boolean {
    const visited = new Set<string>();
    const currentPath = new Set<string>();

    const dfs = (node: string): boolean => {
      if (currentPath.has(node)) return true;
      if (visited.has(node)) return false;

      visited.add(node);
      currentPath.add(node);

      const dependency = matrix[node];
      if (dependency && dfs(dependency)) return true;

      currentPath.delete(node);
      return false;
    };

    return Object.keys(matrix).some(key => dfs(key));
  }

OAuth Scope: None (local validation)

The detectCircularDependencies method prevents dialog engine crashes caused by recursive entity resolution. Cognigy.AI rejects payloads with circular version mappings during the promotion phase.

Step 3: Execute Entity Conflict and Fallback Route Verification

Before promotion, the migrator must verify that target entities do not conflict with existing definitions and that fallback routes remain intact. The following code performs pre-flight validation against the Cognigy.AI entity and routing APIs.

  async verifyEntityConflictsAndFallbacks(intentId: string, versionMatrix: Record<string, string>): Promise<void> {
    const entityIds = Object.keys(versionMatrix);
    
    for (const entityId of entityIds) {
      try {
        const entityResponse = await this.apiClient.get(`/api/v3/entities/${entityId}`);
        const entity = entityResponse.data;

        if (entity.status === 'LOCKED' || entity.status === 'DEPRECATED') {
          throw new Error(`Entity ${entityId} cannot be promoted. Status is ${entity.status}.`);
        }
      } catch (error) {
        if (axios.isAxiosError(error) && error.response?.status === 404) {
          throw new Error(`Entity ${entityId} not found in tenant. Migration aborted.`);
        }
        throw error;
      }
    }

    // Verify fallback route configuration
    const fallbackResponse = await this.apiClient.get(`/api/v3/intents/${intentId}/fallbacks`);
    const fallbacks = fallbackResponse.data.items || [];
    
    if (fallbacks.length === 0) {
      console.warn(`Intent ${intentId} has no fallback routes configured. Dialog may break on unrecognized input.`);
    }

    const activeFallbacks = fallbacks.filter((f: any) => f.isActive);
    if (activeFallbacks.length === 0) {
      throw new Error(`Intent ${intentId} has no active fallback routes. Enable at least one fallback before migration.`);
    }
  }

OAuth Scope: intent:read, entity:read

The fallback route verification ensures that unrecognized user input does not cause unhandled exceptions in the CXone dialog engine. Missing fallbacks are treated as hard failures to prevent broken conversation paths.

Step 4: Perform Atomic PUT Promotion and Environment Sync

The core migration operation uses an atomic PUT request to promote the snapshot. Cognigy.AI processes this synchronously and returns a deployment status. The following code executes the promotion and triggers environment synchronization.

  async promoteVersion(intentId: string, payload: IntentMigratePayload): Promise<string> {
    const versionId = uuidv4();
    const startTime = Date.now();
    this.metrics.startTime = startTime;

    try {
      const response = await this.apiClient.put(
        `/api/v3/intents/${intentId}/versions/${versionId}/promote`,
        payload,
        {
          headers: {
            'X-Request-ID': `migrate-${uuidv4()}`,
            'Idempotency-Key': `intent-${intentId}-v${payload.targetVersion}`
          }
        }
      );

      const deploymentId = response.data.deploymentId;
      this.metrics.latencyMs = Date.now() - startTime;
      this.metrics.successCount++;
      this.metrics.endTime = Date.now();

      console.log(`Promotion successful. Deployment ID: ${deploymentId}`);
      return deploymentId;
    } catch (error) {
      this.metrics.failureCount++;
      this.metrics.endTime = Date.now();
      if (axios.isAxiosError(error)) {
        throw new Error(`Promotion failed with status ${error.response?.status}: ${error.response?.data}`);
      }
      throw error;
    }
  }

  async syncEnvironment(environmentId: string): Promise<void> {
    try {
      await this.apiClient.post(`/api/v3/environments/${environmentId}/sync`, {
        triggerSource: 'api-migration',
        forceRefresh: true
      });
      console.log(`Environment ${environmentId} sync triggered.`);
    } catch (error) {
      if (axios.isAxiosError(error)) {
        console.error(`Environment sync failed: ${error.response?.data}`);
      }
      throw error;
    }
  }

OAuth Scope: intent:write, deployment:manage, environment:sync

The Idempotency-Key header prevents duplicate promotions if the CI/CD pipeline retries the request. The X-Request-ID header enables trace correlation in Cognigy.AI logs. Environment synchronization propagates the promoted intent to the CXone runtime without requiring a full bot redeployment.

Step 5: Trigger CI/CD Webhooks, Track Metrics, and Generate Audit Logs

Post-migration events must synchronize with external pipelines. The following code registers a webhook, calculates success rates, and writes structured audit logs for release governance.

  async triggerMigrationWebhook(webhookUrl: string, deploymentId: string, intentId: string): Promise<void> {
    try {
      await axios.post(webhookUrl, {
        event: 'INTENT_MIGRATED',
        timestamp: new Date().toISOString(),
        deploymentId,
        intentId,
        metrics: this.metrics,
        environment: process.env.COGNIGY_TARGET_ENV || 'production'
      }, {
        headers: { 'Content-Type': 'application/json', 'X-Webhook-Secret': process.env.WEBHOOK_SECRET || '' }
      });
    } catch (error) {
      console.error(`Webhook delivery failed: ${error}`);
    }
  }

  generateAuditLog(intentId: string, payload: IntentMigratePayload, deploymentId: string): string {
    const auditEntry = {
      auditId: uuidv4(),
      timestamp: new Date().toISOString(),
      action: 'INTENT_VERSION_MIGRATE',
      intentId,
      snapshotId: payload.snapshotId,
      targetVersion: payload.targetVersion,
      deploymentId,
      latencyMs: this.metrics.latencyMs,
      successRate: this.metrics.successCount / (this.metrics.successCount + this.metrics.failureCount || 1),
      tenantId: process.env.COGNIGY_TENANT_ID,
      environment: process.env.COGNIGY_TARGET_ENV
    };

    const logLine = JSON.stringify(auditEntry);
    fs.appendFileSync('migration-audit.log', logLine + '\n');
    return logLine;
  }

OAuth Scope: None (external webhook and local logging)

The audit log includes latency, success rate, and tenant context for compliance reporting. The webhook payload mirrors CI/CD event schemas used by GitHub Actions, GitLab CI, and Azure DevOps.

import * as fs from 'fs';
import { CognigyAuthClient } from './auth'; // Assume auth class from Step 1 is imported
import { CognigyIntentMigrator } from './migrator'; // Assume migrator class from Steps 2-5 is imported

async function runMigration() {
  const baseURL = process.env.COGNIGY_BASE_URL || 'https://api.cognigy.ai';
  const clientId = process.env.COGNIGY_CLIENT_ID!;
  const clientSecret = process.env.COGNIGY_CLIENT_SECRET!;

  const authClient = new CognigyAuthClient(baseURL, clientId, clientSecret);
  await authClient.getAccessToken();

  const migrator = new CognigyIntentMigrator(authClient);

    console.log('Triggering CI/CD webhook...');
    await migrator.triggerMigrationWebhook(
      process.env.CICD_WEBHOOK_URL!, deploymentId, intentId
    );

    console.log('Generating audit log...');
    const auditLog = migrator.generateAuditLog(intentId, payload, deploymentId);
    console.log('Audit log generated:', auditLog);

    console.log('Migration completed successfully.');
  } catch (error) {
    console.error('Migration failed:', error);
    process.exit(1);
  }
}

runMigration();

This script executes the complete migration pipeline. Replace environment variables with your Cognigy.AI tenant credentials. The script exits with code one on failure to support CI/CD pipeline status detection.

Common Errors & Debugging

Error: 409 Conflict

• Cause: Entity version matrix contains overlapping definitions or the target intent version already exists.
• Fix: Verify that versionMatrix keys map to unique, non-conflicting entity versions. Use GET /api/v3/intents/{id}/versions to check existing version strings.
• Code Fix: Add a pre-check against existing versions before constructing the payload.

Error: 422 Unprocessable Entity

• Cause: Payload fails dialog engine constraint validation or Zod schema parsing.
• Fix: Review the ZodError output. Ensure deployDirective.environmentId matches an active CXone environment UUID. Verify that fallback routes are active.
• Code Fix: Log error.errors from Zod parsing to identify missing or malformed fields.

Error: 429 Too Many Requests

• Cause: Cognigy.AI rate limits are exceeded during batch migrations.
• Fix: Implement exponential backoff. The handleRateLimit method extracts the Retry-After header. Wrap migration loops in a retry decorator with a maximum of three attempts.
• Code Fix: Add a retry wrapper around promoteVersion calls with jittered delays.

Error: 503 Service Unavailable

• Cause: Dialog engine is undergoing maintenance or environment sync is locked.
• Fix: Wait for the lock to release. Cognigy.AI returns a X-Lock-Expires header indicating when the environment becomes available.
• Code Fix: Poll the environment status endpoint until status returns AVAILABLE before retrying.
