TikTok Shop Integration

TikTok Shop has rapidly become a major player in social commerce, combining entertainment with shopping through short-form videos and live streams. Integrating TikTok Shop with StateSet allows you to tap into this growing marketplace while maintaining centralized control.

TikTok Shop Setup

Create TikTok Shop Seller Account

Visit TikTok Shop Seller Center
Complete the business verification process
Set up your shop profile and policies
Configure shipping and return settings

Generate API Credentials

Navigate to the API settings in TikTok Shop Seller Center:

// TikTok Shop API Configuration
const tiktokConfig = {
  appKey: process.env.TIKTOK_APP_KEY,
  appSecret: process.env.TIKTOK_APP_SECRET,
  shopId: process.env.TIKTOK_SHOP_ID,
  accessToken: null // Will be set after OAuth
};

OAuth Authentication

Implement TikTok Shop OAuth flow:

import { StateSetClient } from 'StateSet-node';
import axios from 'axios';
import crypto from 'crypto';

class TikTokShopConnector {
  constructor(config) {
    this.config = config;
    this.baseURL = 'https://open-api.tiktokglobalshop.com';
    this.StateSet = new StateSetClient(process.env.STATESET_API_KEY);
  }
  
  // Generate signature for TikTok API requests
  generateSignature(path, params, body = '') {
    const timestamp = Math.floor(Date.now() / 1000);
    const signString = [
      this.config.appKey,
      path,
      timestamp,
      JSON.stringify(params),
      body
    ].join('');
    
    return crypto
      .createHmac('sha256', this.config.appSecret)
      .update(signString)
      .digest('hex');
  }
  
  // Get OAuth authorization URL
  getAuthorizationURL() {
    const state = crypto.randomBytes(16).toString('hex');
    const params = new URLSearchParams({
      app_key: this.config.appKey,
      state: state,
      redirect_uri: process.env.TIKTOK_REDIRECT_URI
    });
    
    return {
      url: `https://auth.tiktok-shops.com/oauth/authorize?${params}`,
      state: state
    };
  }
  
  // Exchange authorization code for access token
  async getAccessToken(code) {
    const path = '/api/v2/token/get';
    const params = {
      app_key: this.config.appKey,
      app_secret: this.config.appSecret,
      auth_code: code,
      grant_type: 'authorized_code'
    };
    
    const response = await axios.post(
      `${this.baseURL}${path}`,
      params
    );
    
    if (response.data.code === 0) {
      this.config.accessToken = response.data.data.access_token;
      
      // Store token in StateSet
      await this.StateSet.channels.updateCredentials({
        channel: 'tiktok_shop',
        credentials: {
          access_token: response.data.data.access_token,
          refresh_token: response.data.data.refresh_token,
          expires_at: new Date(Date.now() + response.data.data.expires_in * 1000)
        }
      });
      
      return response.data.data;
    }
    
    throw new Error(`TikTok OAuth failed: ${response.data.message}`);
  }
}

Product Synchronization

Synchronize your product catalog with TikTok Shop while handling platform-specific requirements:

class TikTokProductSync {
  constructor(connector, StateSet) {
    this.connector = connector;
    this.StateSet = StateSet;
  }
  
  // Map StateSet product to TikTok Shop format
  mapProductToTikTok(product) {
    return {
      title: product.name,
      description: this.formatDescription(product.description),
      category_id: this.mapCategory(product.category),
      brand: product.brand || 'Unbranded',
      images: product.images.map(img => ({ url: img.url })),
      skus: product.variants.map(variant => ({
        seller_sku: variant.sku,
        price: {
          amount: variant.price * 100, // TikTok uses cents
          currency: 'USD'
        },
        inventory: [{
          warehouse_id: process.env.TIKTOK_WAREHOUSE_ID,
          quantity: variant.inventory_quantity
        }],
        sales_attributes: this.mapVariantAttributes(variant)
      })),
      package_dimensions: {
        length: product.dimensions?.length || 10,
        width: product.dimensions?.width || 10,
        height: product.dimensions?.height || 10,
        unit: 'CENTIMETER',
        weight: product.weight || 100,
        weight_unit: 'GRAM'
      },
      is_cod_allowed: false,
      delivery_service_ids: [process.env.TIKTOK_DELIVERY_SERVICE_ID]
    };
  }
  
  // Sync products from StateSet to TikTok Shop
  async syncProducts(options = {}) {
    const { limit = 100, offset = 0 } = options;
    
    try {
      // Fetch products from StateSet
      const products = await this.StateSet.products.list({
        limit,
        offset,
        expand: ['variants', 'images']
      });
      
      const results = {
        success: [],
        failed: [],
        skipped: []
      };
      
      for (const product of products.data) {
        try {
          // Check if product should be listed on TikTok
          if (!product.channels?.includes('tiktok_shop')) {
            results.skipped.push({
              sku: product.sku,
              reason: 'Not enabled for TikTok Shop'
            });
            continue;
          }
          
          // Map and validate product data
          const tiktokProduct = this.mapProductToTikTok(product);
          
          // Create or update product on TikTok
          const response = await this.createOrUpdateProduct(tiktokProduct);
          
          // Update StateSet with TikTok product ID
          await this.StateSet.products.update(product.id, {
            external_ids: {
              ...product.external_ids,
              tiktok_shop: response.product_id
            }
          });
          
          results.success.push({
            sku: product.sku,
            tiktok_id: response.product_id
          });
          
        } catch (error) {
          results.failed.push({
            sku: product.sku,
            error: error.message
          });
        }
      }
      
      // Log sync results
      await this.StateSet.logs.create({
        type: 'channel_sync',
        channel: 'tiktok_shop',
        action: 'product_sync',
        results: results,
        timestamp: new Date()
      });
      
      return results;
      
    } catch (error) {
      logger.error('Product sync failed:', error);
      throw error;
    }
  }
  
  // Format description for TikTok requirements
  formatDescription(description) {
    // TikTok has specific requirements for product descriptions
    let formatted = description
      .replace(/<[^>]*>/g, '') // Remove HTML tags
      .substring(0, 2000); // Max 2000 characters
    
    // Add required disclaimers if needed

      // Add more mappings based on TikTok's category tree
    };
    
    return categoryMap[StateSetCategory] || '9999'; // Default category
  }
}

Order Management

Handle TikTok Shop orders and sync them with your StateSet order management system:

class TikTokOrderManager {
  constructor(connector, StateSet) {
    this.connector = connector;
    this.StateSet = StateSet;
  }
  
  // Fetch new orders from TikTok Shop
  async fetchNewOrders() {
    const path = '/api/orders/search';
    const params = {
      create_time_from: Math.floor((Date.now() - 3600000) / 1000), // Last hour
      create_time_to: Math.floor(Date.now() / 1000),
      order_status: 'AWAITING_SHIPMENT',
      page_size: 100
    };
    
    const orders = await this.connector.makeRequest('POST', path, params);
    
    for (const tiktokOrder of orders.data.orders) {
      await this.processOrder(tiktokOrder);
    }
  }
  
  // Process individual TikTok order
  async processOrder(tiktokOrder) {
    try {
      // Check if order already exists
      const existingOrder = await this.StateSet.orders.list({
        external_id: tiktokOrder.order_id,
        channel: 'tiktok_shop'
      });
      
      if (existingOrder.data.length > 0) {
        return; // Order already processed
      }
      
      // Create order in StateSet
      const StateSetOrder = await this.StateSet.orders.create({
        external_id: tiktokOrder.order_id,
        channel: 'tiktok_shop',
        customer: {
          email: tiktokOrder.buyer_email || `tiktok_${tiktokOrder.buyer_user_id}@example.com`,
          name: tiktokOrder.recipient_address.name,
          phone: tiktokOrder.recipient_address.phone
        },
        shipping_address: {
          line1: tiktokOrder.recipient_address.address_line1,
          line2: tiktokOrder.recipient_address.address_line2,
          city: tiktokOrder.recipient_address.city,
          state: tiktokOrder.recipient_address.state,
          postal_code: tiktokOrder.recipient_address.zipcode,
          country: tiktokOrder.recipient_address.country_code
        },

          sku: item.seller_sku,
          name: item.product_name,
          quantity: item.quantity,
          price: item.sku_original_price / 100, // Convert from cents
          discount: item.sku_platform_discount / 100
        })),
        subtotal: tiktokOrder.payment_info.sub_total / 100,
        shipping_cost: tiktokOrder.payment_info.shipping_fee / 100,
        tax: tiktokOrder.payment_info.tax / 100,

          tiktok_carrier: tiktokOrder.shipping_provider
        }
      });
      
      // Create webhook for order updates
      await this.StateSet.webhooks.subscribe({
        url: process.env.WEBHOOK_URL,
        events: [`order.${StateSetOrder.id}.updated`],
        metadata: {
          channel: 'tiktok_shop',
          external_order_id: tiktokOrder.order_id
        }
      });
      
      logger.info(`Created order ${StateSetOrder.id} from TikTok order ${tiktokOrder.order_id}`);
      
    } catch (error) {
      logger.error(`Failed to process TikTok order ${tiktokOrder.order_id}:`, error);
      
      // Log error for manual review

        error: error.message,
        raw_data: tiktokOrder
      });
    }
  }
}

Live Commerce Integration

TikTok Shop’s unique live streaming features require special handling:

class TikTokLiveCommerce {
  constructor(connector, StateSet) {
    this.connector = connector;
    this.StateSet = StateSet;
  }
  
  // Create live stream session
  async createLiveSession(sessionData) {
    const products = await this.StateSet.products.list({
      ids: sessionData.product_ids
    });
    
    // Register products for live stream
    const liveProducts = await this.connector.makeRequest(
      'POST',
      '/api/products/live_stream/add',
      {
        product_ids: products.data.map(p => p.external_ids.tiktok_shop),
        session_id: sessionData.session_id
      }
    );
    
    // Create campaign in StateSet
    const campaign = await this.StateSet.campaigns.create({
      name: sessionData.name,
      type: 'live_stream',
      channel: 'tiktok_shop',
      start_date: sessionData.start_time,
      end_date: sessionData.end_time,
      products: sessionData.product_ids,
      metadata: {
        tiktok_session_id: sessionData.session_id,
        host: sessionData.host_username,
        expected_viewers: sessionData.expected_viewers
      }
    });
    
    return campaign;
  }
  
  // Track live stream performance
  async trackLiveMetrics(sessionId) {
    const metrics = await this.connector.makeRequest(
      'GET',
      `/api/live_stream/metrics/${sessionId}`
    );
    
    await this.StateSet.analytics.create({
      type: 'live_stream_metrics',
      channel: 'tiktok_shop',
      session_id: sessionId,
      metrics: {
        viewers: metrics.viewer_count,
        engagement_rate: metrics.engagement_rate,
        conversion_rate: metrics.conversion_rate,
        revenue: metrics.total_revenue / 100,
        orders: metrics.order_count,
        top_products: metrics.top_selling_products
      },
      timestamp: new Date()
    });
  }
}

Amazon Integration

Amazon remains the largest e-commerce marketplace globally. Integrating with Amazon through their SP-API (Selling Partner API) enables automated inventory management, order processing, and listing optimization.

Amazon SP-API Setup

Go to Amazon Developer Portal
Register your application
Define your app’s data access requirements
Complete the approval process

Configure SP-API Credentials

Set up your Amazon SP-API configuration:

const amazonConfig = {
  clientId: process.env.AMAZON_CLIENT_ID,
  clientSecret: process.env.AMAZON_CLIENT_SECRET,
  refreshToken: process.env.AMAZON_REFRESH_TOKEN,
  region: 'na', // na, eu, fe
  marketplace: 'ATVPDKIKX0DER', // US marketplace ID
};

Implement Authentication

Create an Amazon connector with LWA (Login with Amazon) authentication:

import { SellingPartnerAPI } from 'amazon-sp-api';
import { StateSetClient } from 'StateSet-node';

class AmazonConnector {
  constructor(config) {
    this.config = config;
    this.StateSet = new StateSetClient(process.env.STATESET_API_KEY);
    this.sp = new SellingPartnerAPI({
      region: config.region,
      refresh_token: config.refreshToken,
      credentials: {
        SELLING_PARTNER_APP_CLIENT_ID: config.clientId,
        SELLING_PARTNER_APP_CLIENT_SECRET: config.clientSecret,
      },
    });
  }
  
  async testConnection() {
    try {
      const markets = await this.sp.callAPI({
        operation: 'getMarketplaceParticipations',
        endpoint: 'sellers',
      });
      logger.info('Connected to Amazon marketplaces:', markets);
      return true;
    } catch (error) {
      logger.error('Amazon connection failed:', error);
      return false;
    }
  }
}

Product Listing Management

class AmazonProductManager {
  constructor(connector) {
    this.connector = connector;
    this.sp = connector.sp;
    this.StateSet = connector.StateSet;
  }
  
  // Create or update Amazon listing
  async createListing(product) {
    const feedDocument = await this.createProductFeed(product);
    
    // Submit feed to Amazon
    const feed = await this.sp.callAPI({
      operation: 'createFeed',
      endpoint: 'feeds',
      body: {
        feedType: 'POST_PRODUCT_DATA',
        marketplaceIds: [this.connector.config.marketplace],
        inputFeedDocumentId: feedDocument.feedDocumentId,
      },
    });
    
    // Monitor feed processing
    await this.monitorFeed(feed.feedId);
    
    // Update StateSet with Amazon ASIN
    const catalogItem = await this.getProductBySkU(product.sku);
    await this.StateSet.products.update(product.id, {
      external_ids: {
        ...product.external_ids,
        amazon_asin: catalogItem.asin,
      },
    });

Inventory Reconciliation

class InventoryReconciliation {
  constructor(StateSet) {
    this.StateSet = StateSet;
  }
  
  // Daily reconciliation process
  async performReconciliation() {
    const discrepancies = [];
    const products = await this.StateSet.products.list();
    
    for (const product of products.data) {
      // Get inventory from each channel
      const channelInventory = await Promise.all([
        this.getTikTokInventory(product.sku),
        this.getAmazonInventory(product.sku),
        this.getWalmartInventory(product.sku),
        this.getShopifyInventory(product.sku),
      ]);
      
      // Compare with StateSet master inventory
      const StateSetInventory = await this.StateSet.inventory.get(product.sku);
      
      channelInventory.forEach((inv, index) => {
        if (inv && Math.abs(inv.quantity - StateSetInventory.available_quantity) > 0) {
          discrepancies.push({
            sku: product.sku,
            channel: ['tiktok', 'amazon', 'walmart', 'shopify'][index],
            channel_quantity: inv.quantity,
            StateSet_quantity: StateSetInventory.available_quantity,
            difference: inv.quantity - StateSetInventory.available_quantity,
          });
        }
      });
    }
    
    // Auto-resolve minor discrepancies
    for (const discrepancy of discrepancies) {
      if (Math.abs(discrepancy.difference) <= 5) {
        await this.autoResolveDiscrepancy(discrepancy);
      } else {
        await this.flagForManualReview(discrepancy);
      }
    }
    
    return {
      total_checked: products.data.length,
      discrepancies_found: discrepancies.length,
      auto_resolved: discrepancies.filter(d => Math.abs(d.difference) <= 5).length,
      manual_review_required: discrepancies.filter(d => Math.abs(d.difference) > 5).length,
    };
  }
}

Pricing Strategies

Dynamic pricing across channels requires careful consideration of platform fees, competition, and margin requirements.

Dynamic Pricing Engine

class MultiChannelPricingEngine {
  constructor(StateSet) {
    this.StateSet = StateSet;
    this.channelFees = {
      tiktok_shop: 0.05, // 5% commission
      amazon: 0.15, // 15% average referral fee
      walmart: 0.15, // 15% referral fee
      shopify: 0.029, // 2.9% + $0.30 transaction fee
    };
  }
  
  // Calculate channel-specific pricing
  async calculateChannelPrices(product, targetMargin = 0.30) {
    const baseCost = product.cost || 0;
    const prices = {};
    
    for (const [channel, feeRate] of Object.entries(this.channelFees)) {
      // Calculate minimum price to achieve target margin
      const minPrice = baseCost / (1 - targetMargin - feeRate);
      
      // Get competitive pricing data
      const competitorPrices = await this.getCompetitorPrices(product.sku, channel);
      
      // Determine optimal price
      prices[channel] = {
        minimum: Math.ceil(minPrice * 100) / 100,
        competitive: competitorPrices.median,
        recommended: this.calculateOptimalPrice(minPrice, competitorPrices),
        margin: this.calculateMargin(prices[channel].recommended, baseCost, feeRate),
      };
    }
    
    return prices;
  }
  
  // Implement repricing strategies
  async implementRepricingStrategy(strategy = 'competitive') {
    const products = await this.StateSet.products.list({ active: true });
    
    for (const product of products.data) {
      const channelPrices = await this.calculateChannelPrices(product);
      
      // Update prices on each channel
      await Promise.all([
        this.updateTikTokPrice(product.sku, channelPrices.tiktok_shop.recommended),
        this.updateAmazonPrice(product.sku, channelPrices.amazon.recommended),
        this.updateWalmartPrice(product.sku, channelPrices.walmart.recommended),
        this.updateShopifyPrice(product.sku, channelPrices.shopify.recommended),
      ]);
      
      // Log pricing changes
      await this.StateSet.pricing_history.create({
        sku: product.sku,
        timestamp: new Date(),
        strategy: strategy,
        prices: channelPrices,
      });
    }
  }
}

Analytics and Reporting

Comprehensive analytics across all channels provide insights for optimization and growth.

Multi-Channel Analytics Dashboard

class MultiChannelAnalytics {
  constructor(StateSet) {
    this.StateSet = StateSet;
  }
  
  // Generate comprehensive channel performance report
  async generateChannelReport(dateRange) {
    const channels = ['tiktok_shop', 'amazon', 'walmart', 'shopify'];
    const report = {
      summary: {},
      by_channel: {},
      top_products: [],
      recommendations: [],
    };
    
    // Aggregate data for each channel
    for (const channel of channels) {
      const channelData = await this.getChannelMetrics(channel, dateRange);
      
      report.by_channel[channel] = {
        revenue: channelData.revenue,
        orders: channelData.order_count,
        aov: channelData.revenue / channelData.order_count,
        conversion_rate: channelData.conversion_rate,
        return_rate: channelData.return_rate,
        profit_margin: channelData.profit_margin,
        top_products: channelData.top_products.slice(0, 5),
      };
    }
    
    // Calculate summary metrics
    report.summary = {
      total_revenue: Object.values(report.by_channel).reduce((sum, ch) => sum + ch.revenue, 0),
      total_orders: Object.values(report.by_channel).reduce((sum, ch) => sum + ch.orders, 0),
      average_margin: this.calculateWeightedAverage(report.by_channel, 'profit_margin', 'revenue'),
      best_channel: this.identifyBestChannel(report.by_channel),
    };
    
    // Generate recommendations
    report.recommendations = this.generateRecommendations(report);
    
    return report;
  }
  
  // Real-time performance monitoring
  async monitorPerformance() {
    const alerts = [];
    
    // Check inventory levels
    const lowStock = await this.checkLowStockItems();
    if (lowStock.length > 0) {
      alerts.push({
        type: 'LOW_STOCK',
        severity: 'HIGH',
        items: lowStock,
        action: 'Reorder immediately to prevent stockouts',
      });
    }
    
    // Check pricing competitiveness
    const pricingIssues = await this.checkPricingCompetitiveness();
    if (pricingIssues.length > 0) {
      alerts.push({
        type: 'PRICING_ALERT',
        severity: 'MEDIUM',
        items: pricingIssues,
        action: 'Review and adjust pricing to remain competitive',
      });
    }
    
    // Check channel performance
    const performanceIssues = await this.checkChannelPerformance();
    performanceIssues.forEach(issue => alerts.push(issue));
    
    return alerts;
  }
}

Best Practices

1. Channel-Specific Optimization

Each platform has unique requirements and best practices:

TikTok Shop
Amazon
Walmart

Use trending sounds and hashtags in product videos
Partner with influencers for live selling events
Optimize for mobile-first shopping experience
Leverage TikTok’s algorithm with engaging content

2. Inventory Management

// Best practice: Implement safety stock calculations
function calculateSafetyStock(sku, leadTime, servicelevel = 0.95) {
  const dailyDemand = getAverageDailyDemand(sku);
  const demandStdDev = getDemandStandardDeviation(sku);
  const zScore = getZScore(servicelevel); // 1.65 for 95% service level
  
  return Math.ceil(zScore * Math.sqrt(leadTime) * demandStdDev);
}

3. Order Processing Automation

// Best practice: Implement automated order routing
class AutomatedOrderRouter {
  async routeOrder(order) {
    const rules = [
      { condition: o => o.shipping_speed === 'express', action: 'route_to_nearest_warehouse' },
      { condition: o => o.total > 500, action: 'flag_for_fraud_review' },
      { condition: o => o.channel === 'amazon' && o.is_prime, action: 'route_to_fba' },
      { condition: o => o.items.some(i => i.is_hazmat), action: 'route_to_specialized_fulfillment' },
    ];
    
    for (const rule of rules) {
      if (rule.condition(order)) {
        return this.executeAction(rule.action, order);
      }
    }
    
    return this.defaultRouting(order);
  }
}

Troubleshooting

Common Integration Issues

Authentication Failures

Problem: API authentication fails across channelsSolutions:

Verify API credentials are correctly set in environment variables
Check if tokens have expired and need refresh
Ensure IP whitelisting is configured if required
Validate signature generation for platforms like Walmart

// Debug authentication
async function debugAuth(channel) {
  logger.info(`Testing ${channel} authentication...`);
  try {
    const result = await testChannelConnection(channel);
    logger.info('Success:', result);
  } catch (error) {
    logger.error('Auth failed:', error.message);
    logger.info('Check:', getAuthChecklistForChannel(channel););
  }
}

Inventory Sync Discrepancies

Problem: Inventory levels don’t match across channelsSolutions:

Implement regular reconciliation jobs
Use webhooks for real-time updates
Add buffer stock to prevent overselling
Log all inventory movements for audit trail

Order Processing Delays

Problem: Orders take too long to processSolutions:

Implement parallel processing for bulk operations
Use queue systems for order processing
Optimize API calls with batch operations
Cache frequently accessed data
