Managing Genesys Cloud Outbound Call Scripts via API with TypeScript

What You Will Build

A TypeScript module that constructs, validates, publishes, and simulates Genesys Cloud outbound call scripts using the official SDK, while exporting metadata, tracking analytics, and generating audit logs. This tutorial demonstrates programmatic script lifecycle management from payload construction to activation polling and compliance auditing. The implementation uses TypeScript with the @genesyscloud/purecloud-platform-client-v2 SDK.

Prerequisites

• OAuth client configured with JWT grant type
• Required OAuth scopes: script:write, script:read, analytics:read, audit:read
• SDK: @genesyscloud/purecloud-platform-client-v2@^3.0.0
• Runtime: Node.js 18 or higher
• Dependencies: npm install @genesyscloud/purecloud-platform-client-v2 axios

Authentication Setup

Genesys Cloud uses OAuth 2.0 for API access. The JWT grant flow is recommended for server-side integrations. The SDK handles token refresh automatically when configured correctly. You must pass the environment region, client ID, and JWT token to the AuthApi before initializing other service clients.

import { PlatformClient, AuthApi, ScriptsApi, AnalyticsApi, AuditApi } from '@genesyscloud/purecloud-platform-client-v2';

export async function initializeGenesysClient(
  region: string,
  clientId: string,
  jwtToken: string
): Promise<PlatformClient> {
  const client = PlatformClient.create({ region: region });
  const authApi = new AuthApi(client);

  try {
    await authApi.postOAuthTokenJWTGrant({
      body: {
        client_id: clientId,
        grant_type: 'jwt_bearer',
        assertion: jwtToken
      }
    });
  } catch (error: any) {
    if (error.response?.status === 401) {
      throw new Error('OAuth authentication failed. Verify JWT token and client ID.');
    }
    throw error;
  }

  return client;
}

The AuthApi.postOAuthTokenJWTGrant call establishes the session. The SDK caches the access token and automatically appends it to subsequent requests. You must handle 401 responses explicitly when tokens expire or are malformed.

Implementation

Step 1: Construct Script Definition Payload with Dynamic Branching

Scripts in Genesys Cloud are represented as directed graphs of nodes. Each node contains prompts, conditions, and edges. You must define variables for runtime data binding and transfer targets for disposition routing. The payload structure below demonstrates conditional branching based on interaction attributes and customer segment data.

import { Script, ScriptNode, ScriptCondition, ScriptEdge, ScriptVariable, ScriptTransferTarget } from '@genesyscloud/purecloud-platform-client-v2';

export function buildOutboundScriptPayload(name: string, version: string): Partial<Script> {
  const customerIdVariable: ScriptVariable = {
    id: 'var_customerId',
    name: 'customer_id',
    type: 'string'
  };

  const segmentVariable: ScriptVariable = {
    id: 'var_segment',
    name: 'customer_segment',
    type: 'string'
  };

  const highValueCondition: ScriptCondition = {
    id: 'cond_high_value',
    type: 'equals',
    left: { variableId: 'var_segment' },
    right: { value: 'platinum' }
  };

  const premiumTransfer: ScriptTransferTarget = {
    id: 'transfer_premium',
    name: 'Premium Support Queue',
    queueId: 'queue_premium_support_uuid',
    type: 'queue'
  };

  const standardTransfer: ScriptTransferTarget = {
    id: 'transfer_standard',
    name: 'Standard Support Queue',
    queueId: 'queue_standard_support_uuid',
    type: 'queue'
  };

  const entryNode: ScriptNode = {
    id: 'node_entry',
    name: 'Entry Point',
    type: 'prompt',
    prompts: [{ text: 'Thank you for calling. How may I assist you today?' }],
    edges: [
      {
        id: 'edge_to_segment_check',
        targetId: 'node_segment_check',
        condition: { type: 'always' }
      }
    ]
  };

  const segmentCheckNode: ScriptNode = {
    id: 'node_segment_check',
    name: 'Segment Router',
    type: 'prompt',
    prompts: [{ text: 'Routing based on customer tier.' }],
    edges: [
      {
        id: 'edge_to_premium',
        targetId: 'node_transfer_premium',
        condition: highValueCondition
      },
      {
        id: 'edge_to_standard',
        targetId: 'node_transfer_standard',
        condition: { type: 'always' }
      }
    ]
  };

  const premiumNode: ScriptNode = {
    id: 'node_transfer_premium',
    name: 'Transfer to Premium',
    type: 'transfer',
    transferTarget: premiumTransfer
  };

  const standardNode: ScriptNode = {
    id: 'node_transfer_standard',
    name: 'Transfer to Standard',
    type: 'transfer',
    transferTarget: standardTransfer
  };

  return {
    name: name,
    version: version,
    status: 'draft',
    variables: [customerIdVariable, segmentVariable],
    nodes: [entryNode, segmentCheckNode, premiumNode, standardNode],
    entryNode: entryNode.id,
    interactions: {
      outbound: {
        enabled: true,
        defaultCampaignId: 'campaign_outbound_uuid'
      }
    }
  };
}

The payload constructs a valid script topology. The condition objects on edges determine routing. The type: 'always' edge acts as a fallback when higher priority conditions fail. You must ensure every node has at least one outgoing edge unless it is a terminal transfer or disconnect node.

Step 2: Validate Script Topology and Mandatory Fields

Genesys Cloud rejects scripts with circular references or missing required fields. You must validate the directed graph before submission. The validation function performs a depth-first search to detect cycles and verifies mandatory schema constraints.

export function validateScriptTopology(script: Partial<Script>): { valid: boolean; errors: string[] } {
  const errors: string[] = [];
  if (!script.name || !script.version || !script.entryNode) {
    errors.push('Missing mandatory fields: name, version, or entryNode.');
  }

  if (!script.nodes || script.nodes.length === 0) {
    errors.push('Script must contain at least one node.');
    return { valid: false, errors };
  }

  const nodeMap = new Map<string, any>();
  script.nodes.forEach(n => nodeMap.set(n.id, n));

  const visited = new Set<string>();
  const recursionStack = new Set<string>();

  function hasCycle(nodeId: string): boolean {
    if (recursionStack.has(nodeId)) return true;
    if (visited.has(nodeId)) return false;

    visited.add(nodeId);
    recursionStack.add(nodeId);

    const node = nodeMap.get(nodeId);
    if (!node) return true;

    const edges = node.edges || [];
    for (const edge of edges) {
      if (hasCycle(edge.targetId)) return true;
    }

    recursionStack.delete(nodeId);
    return false;
  }

  for (const nodeId of nodeMap.keys()) {
    if (hasCycle(nodeId)) {
      errors.push(`Circular reference detected starting at node: ${nodeId}`);
    }
  }

  script.nodes.forEach(node => {
    if (!node.id || !node.name || !node.type) {
      errors.push(`Node ${node.id || 'unknown'} missing id, name, or type.`);
    }
    if (node.type !== 'transfer' && (!node.edges || node.edges.length === 0)) {
      errors.push(`Node ${node.id} is not a terminal node but has no outgoing edges.`);
    }
  });

  return { valid: errors.length === 0, errors };
}

The validation enforces graph acyclicity and ensures non-terminal nodes route execution forward. Genesys Cloud uses these constraints to prevent agent lockups during runtime. You must handle validation failures locally to avoid unnecessary API calls.

Step 3: Publish Script and Poll Activation Status

Script publishing is asynchronous. You create the draft via POST /api/v2/scripts, then trigger publication. The platform transitions the script through draft, published, and active states. You must poll the status endpoint until activation completes.

import { ScriptsApi } from '@genesyscloud/purecloud-platform-client-v2';

export async function publishAndActivateScript(
  client: PlatformClient,
  scriptPayload: Partial<Script>,
  maxPollAttempts: number = 15,
  pollIntervalMs: number = 4000
): Promise<string> {
  const scriptsApi = new ScriptsApi(client);
  let scriptId: string = '';

  try {
    const createResponse = await scriptsApi.postScripts({ body: scriptPayload as any });
    scriptId = createResponse.body.id;
    console.log(`Script created with ID: ${scriptId}`);
  } catch (error: any) {
    if (error.response?.status === 409) {
      throw new Error('Version conflict. Update the version string and retry.');
    }
    if (error.response?.status === 400) {
      throw new Error(`Validation failed: ${error.response?.data?.reason || error.message}`);
    }
    throw error;
  }

  // Poll for activation
  let attempts = 0;
  while (attempts < maxPollAttempts) {
    try {
      const statusResponse = await scriptsApi.getScriptsScript({ scriptId: scriptId });
      const status = statusResponse.body.status;

      if (status === 'active') {
        console.log(`Script ${scriptId} is active.`);
        return scriptId;
      }

      if (status === 'failed' || status === 'error') {
        throw new Error(`Script activation failed with status: ${status}`);
      }

      await new Promise(resolve => setTimeout(resolve, pollIntervalMs));
      attempts++;
    } catch (error: any) {
      if (error.response?.status === 429) {
        const retryAfter = parseInt(error.response?.headers['retry-after'] || '5', 10);
        console.log(`Rate limited. Waiting ${retryAfter} seconds before retrying poll.`);
        await new Promise(resolve => setTimeout(resolve, retryAfter * 1000));
        continue;
      }
      throw error;
    }
  }

  throw new Error('Script activation timed out.');
}

The polling loop respects 429 rate limits by parsing the Retry-After header. You must handle 409 version conflicts explicitly because Genesys Cloud enforces immutable version strings for audit compliance. The function returns the script ID once the status reaches active.

Step 4: Export Metadata and Synchronize with External CMS

You retrieve the full script definition via GET /api/v2/scripts/{scriptId} and transform it into a CMS-compatible format. This step strips runtime-only fields and preserves structural metadata for version control systems.

export async function exportScriptMetadata(client: PlatformClient, scriptId: string): Promise<any> {
  const scriptsApi = new ScriptsApi(client);
  
  try {
    const response = await scriptsApi.getScriptsScript({ scriptId: scriptId });
    const script = response.body;

    const cmsPayload = {
      cmsId: `script_${scriptId}`,
      name: script.name,
      version: script.version,
      updatedAt: script.updatedAt,
      authorId: script.authorId,
      nodeCount: script.nodes?.length || 0,
      variableCount: script.variables?.length || 0,
      entryPoint: script.entryNode,
      structureHash: generateStructureHash(script.nodes || []),
      tags: extractTags(script)
    };

    return cmsPayload;
  } catch (error: any) {
    if (error.response?.status === 404) {
      throw new Error(`Script ${scriptId} not found.`);
    }
    throw error;
  }
}

function generateStructureHash(nodes: any[]): string {
  const serialized = JSON.stringify(nodes.map(n => ({ id: n.id, type: n.type, edgeCount: n.edges?.length || 0 })));
  let hash = 0;
  for (let i = 0; i < serialized.length; i++) {
    const char = serialized.charCodeAt(i);
    hash = ((hash << 5) - hash) + char;
    hash |= 0;
  }
  return hash.toString(16);
}

function extractTags(script: any): string[] {
  const tags = [];
  if (script.interactions?.outbound?.enabled) tags.push('outbound');
  if (script.nodes?.some(n => n.type === 'transfer')) tags.push('includes_transfer');
  return tags;
}

The export function normalizes the script into a flat metadata object. The structure hash enables diff detection in external CMS platforms. You must map the updatedAt and authorId fields to maintain provenance tracking.

Step 5: Track Usage Metrics and Conversion Rates

Genesys Cloud Analytics API provides interaction data for scripts. You query /api/v2/analytics/scripts/query to retrieve completion rates, average handle time, and disposition conversions.

import { AnalyticsApi } from '@genesyscloud/purecloud-platform-client-v2';

export async function queryScriptAnalytics(
  client: PlatformClient,
  scriptId: string,
  startDate: string,
  endDate: string
): Promise<any> {
  const analyticsApi = new AnalyticsApi(client);

  const queryPayload = {
    query: {
      filter: {
        type: 'equals',
        left: { field: 'scriptId' },
        right: { value: scriptId }
      },
      timeRange: {
        from: startDate,
        to: endDate
      }
    },
    interval: 'P1D',
    metrics: ['interactions', 'averageHandleTime', 'conversions']
  };

  try {
    const response = await analyticsApi.postAnalyticsScriptsQuery({ body: queryPayload as any });
    return {
      totalInteractions: response.body.data?.reduce((sum: number, row: any) => sum + (row.metrics?.interactions?.value || 0), 0),
      averageHandleTime: response.body.data?.[0]?.metrics?.averageHandleTime?.value,
      conversionRate: response.body.data?.[0]?.metrics?.conversions?.value,
      timestamp: response.body.timestamp
    };
  } catch (error: any) {
    if (error.response?.status === 403) {
      throw new Error('Analytics access denied. Verify analytics:read scope.');
    }
    throw error;
  }
}

The analytics query uses ISO 8601 date ranges and returns aggregated metrics. You must parse the data array to calculate totals. The conversions metric tracks successful disposition routing based on your transfer target definitions.

Step 6: Generate Audit Logs for Compliance Tracking

The Audit API records all script modifications. You query /api/v2/audit/records with resourceType=script to generate compliance reports.

import { AuditApi } from '@genesyscloud/purecloud-platform-client-v2';

export async function generateScriptAuditLog(
  client: PlatformClient,
  scriptId: string,
  limit: number = 50
): Promise<any[]> {
  const auditApi = new AuditApi(client);

  try {
    const response = await auditApi.getAuditRecords({
      resourceType: 'script',
      resourceId: scriptId,
      pageSize: limit
    });

    return response.body.entities?.map(record => ({
      timestamp: record.timestamp,
      action: record.action,
      userId: record.userId,
      userName: record.userName,
      changes: record.changes,
      ipAddress: record.ipAddress
    })) || [];
  } catch (error: any) {
    if (error.response?.status === 403) {
      throw new Error('Audit access denied. Verify audit:read scope.');
    }
    throw error;
  }
}

The audit records capture created, updated, published, and archived actions. You must store these records in a compliance database to satisfy regulatory requirements. The changes field contains the exact payload diff.

Step 7: Script Simulator for Agent Training

You build a deterministic simulator that traverses the script JSON without invoking live APIs. This enables offline training and regression testing.

export class ScriptSimulator {
  private nodes: Map<string, any>;
  private variables: Map<string, any>;

  constructor(scriptDefinition: Partial<Script>) {
    this.nodes = new Map();
    scriptDefinition.nodes?.forEach(n => this.nodes.set(n.id, n));
    this.variables = new Map();
    scriptDefinition.variables?.forEach(v => this.variables.set(v.id, v.value || ''));
  }

  setVariable(id: string, value: any) {
    this.variables.set(id, value);
  }

  simulate(inputAttributes: Record<string, any>): { path: string[]; finalNode: string; outputs: string[] } {
    const path: string[] = [];
    const outputs: string[] = [];
    let currentNodeId = this.nodes.keys().next().value; // Fallback to first if entryNode missing
    if (this.nodes.has('node_entry')) currentNodeId = 'node_entry';

    while (currentNodeId && this.nodes.has(currentNodeId)) {
      path.push(currentNodeId);
      const node = this.nodes.get(currentNodeId);

      if (node.type === 'prompt' && node.prompts) {
        outputs.push(node.prompts[0].text);
      }

      if (node.type === 'transfer') {
        break;
      }

      const edges = node.edges || [];
      let nextNodeId: string | null = null;

      for (const edge of edges) {
        if (this.evaluateCondition(edge.condition, inputAttributes)) {
          nextNodeId = edge.targetId;
          break;
        }
      }

      if (!nextNodeId && edges.length > 0) {
        nextNodeId = edges[edges.length - 1].targetId;
      }

      currentNodeId = nextNodeId;
    }

    return { path, finalNode: currentNodeId || 'none', outputs };
  }

  private evaluateCondition(condition: any, attributes: Record<string, any>): boolean {
    if (!condition || condition.type === 'always') return true;
    if (condition.type === 'equals') {
      const leftVal = this.resolveValue(condition.left, attributes);
      const rightVal = condition.right?.value;
      return leftVal === rightVal;
    }
    return true;
  }

  private resolveValue(ref: any, attributes: Record<string, any>): any {
    if (ref.variableId) return this.variables.get(ref.variableId);
    if (ref.field) return attributes[ref.field];
    return ref.value;
  }
}

The simulator evaluates conditions against a static variable map and input attributes. It returns the execution path and prompt outputs. You must test this simulator against known customer segments to verify routing logic before publishing.

Complete Working Example

import { PlatformClient } from '@genesyscloud/purecloud-platform-client-v2';
import { initializeGenesysClient } from './auth';
import { buildOutboundScriptPayload, validateScriptTopology } from './scriptBuilder';
import { publishAndActivateScript } from './scriptPublisher';
import { exportScriptMetadata } from './cmsExporter';
import { queryScriptAnalytics } from './analytics';
import { generateScriptAuditLog } from './audit';
import { ScriptSimulator } from './simulator';

async function main() {
  const REGION = 'us-east-1';
  const CLIENT_ID = 'your_client_id';
  const JWT_TOKEN = 'your_jwt_token';

  const client: PlatformClient = await initializeGenesysClient(REGION, CLIENT_ID, JWT_TOKEN);

  const scriptName = 'Outbound Campaign Alpha';
  const scriptVersion = 'v1.0.0';

  const payload = buildOutboundScriptPayload(scriptName, scriptVersion);
  const validation = validateScriptTopology(payload);

  if (!validation.valid) {
    console.error('Validation failed:', validation.errors);
    return;
  }

  console.log('Topology valid. Publishing script...');
  const scriptId = await publishAndActivateScript(client, payload);

  const cmsData = await exportScriptMetadata(client, scriptId);
  console.log('CMS Export:', JSON.stringify(cmsData, null, 2));

  const simulator = new ScriptSimulator(payload);
  simulator.setVariable('var_segment', 'platinum');
  const simResult = simulator.simulate({ customerTier: 'platinum' });
  console.log('Simulation Path:', simResult.path);
  console.log('Simulation Outputs:', simResult.outputs);

  const startDate = new Date(Date.now() - 86400000).toISOString();
  const endDate = new Date().toISOString();
  const analytics = await queryScriptAnalytics(client, scriptId, startDate, endDate);
  console.log('Analytics:', analytics);

  const auditLog = await generateScriptAuditLog(client, scriptId);
  console.log('Audit Records:', auditLog.length);
}

main().catch(err => console.error('Execution failed:', err));

This module chains authentication, validation, publishing, export, simulation, analytics, and auditing into a single workflow. You must replace credentials and queue IDs before execution. The script runs synchronously through each phase and logs structured output.

Common Errors & Debugging

Error: 409 Conflict on POST /api/v2/scripts

• Cause: The version string already exists in the tenant. Genesys Cloud enforces unique version identifiers per script name.
• Fix: Increment the version string using semantic versioning before retrying. Ensure your CI pipeline generates unique versions.
• Code Fix: Validate version uniqueness locally or catch 409 and retry with a timestamp suffix.

Error: 429 Too Many Requests

• Cause: Rate limit exceeded on analytics or audit endpoints. The platform enforces per-user and per-tenant quotas.
• Fix: Implement exponential backoff with jitter. Parse the Retry-After header from the response.
• Code Fix: The polling loop in Step 3 demonstrates header parsing. Apply the same pattern to analytics and audit calls.

Error: 400 Bad Request with reason “Invalid node topology”

• Cause: Missing outgoing edges on non-terminal nodes or unresolved variable references in conditions.
• Fix: Run the local validation function before submission. Verify that every condition.left references a defined variable or interaction field.
• Code Fix: Add a schema validator that checks variable ID existence across all node conditions.

Error: 403 Forbidden on Analytics or Audit

• Cause: Missing OAuth scopes or user lacks role permissions.
• Fix: Ensure the OAuth client has analytics:read and audit:read scopes. Verify the authenticated user holds the Analytics Viewer or Administrator role.
• Code Fix: Check error.response?.status === 403 and log the required scopes explicitly.
