  • Amazon reviews your use case and business model
  • Agencies benefit from streamlined approval for multi-client management
  • Technical documentation access granted upon approval

👨‍💻 Authentication Setup (Python)


import requests
import time
from datetime import datetime, timedelta

class AmazonAdsAuth:
    """
    Handles authentication for Amazon Advertising API
    """
    def __init__(self, client_id, client_secret, refresh_token):
        self.client_id = client_id
        self.client_secret = client_secret
        self.refresh_token = refresh_token
        self.access_token = None
        self.token_expiry = None
        self.base_url = "https://advertising-api.amazon.com"
    
    def get_access_token(self):
        """Get valid access token, refresh if expired"""
        if self.access_token and self.token_expiry > datetime.now():
            return self.access_token
        
        # Request new access token
        url = "https://api.amazon.com/auth/o2/token"
        payload = {
            "grant_type": "refresh_token",
            "refresh_token": self.refresh_token,
            "client_id": self.client_id,
            "client_secret": self.client_secret
        }
        
        response = requests.post(url, data=payload)
        
        if response.status_code == 200:
            token_data = response.json()
            self.access_token = token_data["access_token"]
            # Set expiry 5 minutes before actual expiry for safety
            self.token_expiry = datetime.now() + timedelta(
                seconds=token_data["expires_in"] - 300
            )
            return self.access_token
        else:
            raise Exception(f"Auth failed: {response.text}")
    
    def get_headers(self, profile_id):
        """Get headers for API requests"""
        return {
            "Amazon-Advertising-API-ClientId": self.client_id,
            "Authorization": f"Bearer {self.get_access_token()}",
            "Amazon-Advertising-API-Scope": str(profile_id),
            "Content-Type": "application/json"
        }

2. Automated Campaign Management

The foundation of API integration is programmatic campaign management. This enables you to create, modify, and optimize campaigns at scale without manual console work.

Campaign Creation Automation

Creating campaigns programmatically is essential for agencies launching products for multiple clients simultaneously.

👨‍💻 Create Sponsored Products Campaign


def create_campaign(auth, profile_id, campaign_data):
    """
    Create a new Sponsored Products campaign
    """
    endpoint = f"{auth.base_url}/v2/sp/campaigns"
    
    payload = {
        "name": campaign_data["name"],
        "campaignType": "sponsoredProducts",
        "targetingType": campaign_data["targeting_type"],  # "manual" or "auto"
        "state": "enabled",
        "dailyBudget": campaign_data["daily_budget"],
        "startDate": campaign_data["start_date"],  # Format: YYYYMMDD
        "bidding": {
            "strategy": "legacyForSales",  # or "autoForSales"
            "adjustments": [
                {
                    "predicate": "placementTop",
                    "percentage": 100  # +100% for top of search
                }
            ]
        }
    }
    
    response = requests.post(
        endpoint,
        headers=auth.get_headers(profile_id),
        json=payload
    )
    
    if response.status_code == 207:  # Multi-status response
        result = response.json()
        if result["success"]:
            return {
                "success": True,
                "campaign_id": result["campaignId"]
            }
        else:
            return {
                "success": False,
                "error": result["details"]
            }
    else:
        return {
            "success": False,
            "error": response.text
        }

Bulk Keyword Management

Managing thousands of keywords manually is impossible. The API enables bulk operations:

  • Keyword Creation: Add hundreds of keywords in a single API call
  • Bid Updates: Adjust bids across entire campaigns based on performance
  • Negative Keywords: Bulk add negatives to prevent wasted spend
  • Match Type Changes: Convert broad to phrase or exact based on data

Campaign Optimization Workflow

Automated Daily Optimization Process:

  1. Data Retrieval: Pull previous day's performance via Reporting API
  2. Analysis: Calculate ACoS, ROAS, conversion rates by keyword
  3. Decision Logic: Apply rules-based or ML-based optimization decisions
  4. Bid Adjustments: Update bids via API based on performance
  5. Budget Allocation: Shift budget to high-performing campaigns
  6. Negative Keyword Addition: Add poor performers to negative lists
  7. Reporting: Generate client reports and alert on anomalies

⚡ API Rate Limits & Best Practices

  • Rate Limits: Most endpoints allow 10-25 requests/second
  • Batch Operations: Use bulk endpoints when available (100-1000 items per request)
  • Exponential Backoff: Implement retry logic with increasing delays
  • Request Queuing: Use job queues (Redis, SQS) for high-volume operations
  • Caching: Cache static data (profiles, campaigns) to reduce API calls
  • Asynchronous Processing: Use async/await patterns for parallel requests
  • Error Handling: Log all errors with context for debugging
  • Monitoring: Track API usage, success rates, and response times

3. Real-Time Bid Adjustments

Manual bid management can't compete with algorithmic automation. Real-time (or near real-time) bid optimization is where agencies gain competitive advantage.

Bid Optimization Strategies

1. Performance-Based Bidding

Adjust bids based on historical performance metrics:

  • Increase bids for keywords with ACoS < target by 10-20%
  • Decrease bids for keywords with ACoS > target by 15-25%
  • Pause keywords with no conversions after 100+ clicks
  • Boost top performers to maximize impression share

2. Time-Based Bidding (Dayparting)

Adjust bids by hour of day or day of week:

  • Analyze conversion rates by time period
  • Increase bids 20-50% during high-conversion windows
  • Decrease bids 30-50% during low-conversion periods
  • Consider timezone differences for international markets

3. Inventory-Based Bidding

Coordinate with inventory levels:

  • Reduce bids when inventory is low (< 30 days)
  • Increase bids when inventory is high (> 90 days)
  • Pause campaigns automatically when out of stock
  • Resume with lower bids when inventory is restocked

4. Competitive Response Bidding

React to competitive changes:

  • Monitor lost impression share metrics
  • Automatically increase bids if share drops significantly
  • Adjust based on competitive pricing changes
  • Defend brand terms aggressively

Machine Learning for Bid Optimization

Advanced agencies are implementing ML models for bid prediction:

  • Features: Historical CPC, CTR, CVR, day of week, seasonality, inventory levels
  • Models: Gradient boosting (XGBoost), neural networks, or ensemble methods
  • Output: Optimal bid recommendation with confidence intervals
  • Validation: A/B test ML bids vs rule-based bids to measure lift

4. Custom Reporting Dashboards

The Advertising Console's reporting is limited. Custom dashboards enable deeper insights and better client communication.

Reporting API Capabilities

The Reporting API provides access to detailed performance metrics:

  • Granularity Levels: Campaign, ad group, keyword, product, search term
  • Time Ranges: Daily, weekly, monthly, custom date ranges
  • Metrics: Impressions, clicks, spend, sales, ACoS, ROAS, conversions
  • Attribution: 7-day and 30-day attribution windows

Report Generation Process

  1. Request Report: POST request specifying metrics, date range, and granularity
  2. Polling: Report generation is asynchronous; poll status endpoint
  3. Download: Once ready, download report (JSON, CSV, or gzip formats)
  4. Processing: Parse and load into your database
  5. Aggregation: Calculate derived metrics and trends
  6. Visualization: Display in custom dashboard

👨‍💻 Request Performance Report


def request_report(auth, profile_id, report_config):
    """
    Request a performance report from Amazon Advertising API
    """
    endpoint = f"{auth.base_url}/v2/sp/{report_config['report_type']}/report"
    
    payload = {
        "reportDate": report_config["date"],  # Format: YYYYMMDD
        "metrics": [
            "campaignName",
            "campaignId",
            "impressions",
            "clicks",
            "cost",
            "attributedConversions7d",
            "attributedSales7d",
            "acos"
        ]
    }
    
    response = requests.post(
        endpoint,
        headers=auth.get_headers(profile_id),
        json=payload
    )
    
    if response.status_code == 202:
        report_data = response.json()
        return {
            "success": True,
            "report_id": report_data["reportId"],
            "status": report_data["status"]
        }
    else:
        return {"success": False, "error": response.text}

def download_report(auth, profile_id, report_id):
    """
    Download completed report
    """
    # First check status
    status_endpoint = f"{auth.base_url}/v2/reports/{report_id}"
    status_response = requests.get(
        status_endpoint,
        headers=auth.get_headers(profile_id)
    )
    
    if status_response.status_code == 200:
        status_data = status_response.json()
        
        if status_data["status"] == "SUCCESS":
            # Download report
            report_url = status_data["location"]
            report_response = requests.get(report_url)
            
            if report_response.status_code == 200:
                # Decompress if gzipped
                import gzip
                import json
                
                data = gzip.decompress(report_response.content)
                report_data = json.loads(data)
                
                return {
                    "success": True,
                    "data": report_data
                }
        
        return {
            "success": False,
            "status": status_data["status"]
        }

Dashboard Design Best Practices

Executive Dashboard (Client-Facing):

  • High-level KPIs: Total spend, sales, ACoS, TACoS, ROAS
  • Trend charts: 30-day performance trends
  • Top performers: Best campaigns, keywords, products
  • Budget pacing: Burn rate vs daily budget
  • Competitive benchmarks: Performance vs industry averages

Operational Dashboard (Internal Team):

  • Detailed metrics by campaign, ad group, keyword
  • Bid efficiency analysis and recommendations
  • Search term reports with negative keyword suggestions
  • Budget utilization and opportunity identification
  • A/B test results and statistical significance

5. Multi-Client Campaign Management

The true power of API integration for agencies is managing hundreds of client accounts from a unified platform.

Multi-Account Architecture
