API Integration Issues

Troubleshooting API integration issues, rate limiting, and connectivity problems

This guide helps you resolve issues related to API integrations, rate limiting, timeouts, and connectivity problems with BroxiAI and third-party services.

Rate Limiting Issues

Too Many Requests (429) Errors

Problem: "Too Many Requests" (429) errors when calling APIs

Symptoms:

HTTP 429 status codes
"Rate limit exceeded" messages
API calls being rejected
Temporary service unavailability

Solutions:

Implement Exponential Backoff

import time
import random
from typing import Callable, Any

def api_call_with_retry(func: Callable, max_retries: int = 3) -> Any:
    for attempt in range(max_retries):
        try:
            return func()
        except RateLimitError as e:
            if attempt == max_retries - 1:
                raise e
            
            # Exponential backoff with jitter
            delay = (2 ** attempt) + random.uniform(0, 1)
            print(f"Rate limited. Retrying in {delay:.2f} seconds...")
            time.sleep(delay)

# Usage
result = api_call_with_retry(lambda: make_api_call())

Check Rate Limits

# Check current usage
curl -H "Authorization: Bearer $TOKEN" \
     "https://api.broxi.ai/v1/usage" | jq

# Response includes rate limit info
{
  "requests_remaining": 450,
  "requests_limit": 500,
  "reset_time": "2024-01-01T12:00:00Z",
  "window": "hour"
}

Rate Limit Management
- Monitor API usage regularly
- Upgrade plan if hitting limits frequently
- Distribute requests over time
- Use batch operations when available

Implement Request Queuing

import asyncio
from asyncio import Queue
import aiohttp

class RateLimitedClient:
    def __init__(self, requests_per_second: float = 1.0):
        self.rate_limit = requests_per_second
        self.queue = Queue()
        self.last_request_time = 0
    
    async def make_request(self, url: str, **kwargs):
        # Add rate limiting logic
        current_time = time.time()
        time_since_last = current_time - self.last_request_time
        min_interval = 1.0 / self.rate_limit
        
        if time_since_last < min_interval:
            await asyncio.sleep(min_interval - time_since_last)
        
        # Make the actual request
        async with aiohttp.ClientSession() as session:
            async with session.get(url, **kwargs) as response:
                self.last_request_time = time.time()
                return await response.json()

BroxiAI Rate Limits

Current Limits (as of latest update):

Free Plan: 100 requests/hour, 1,000 requests/day
Pro Plan: 1,000 requests/hour, 10,000 requests/day
Enterprise: Custom limits

Monitoring Usage:

# Get current usage stats
curl -H "Authorization: Bearer $TOKEN" \
     "https://api.broxi.ai/v1/account/usage"

Connection and Timeout Issues

API Timeouts

Problem: API calls timing out before completion

Solutions:

Adjust Timeout Settings

import requests
from requests.adapters import HTTPAdapter
from urllib3.util.retry import Retry

# Configure session with custom timeouts
session = requests.Session()

# Retry strategy
retry_strategy = Retry(
    total=3,
    backoff_factor=1,
    status_forcelist=[429, 500, 502, 503, 504],
)

adapter = HTTPAdapter(max_retries=retry_strategy)
session.mount("http://", adapter)
session.mount("https://", adapter)

# Make request with custom timeout
response = session.get(
    "https://api.broxi.ai/v1/flows",
    timeout=(10, 30),  # (connect_timeout, read_timeout)
    headers={"Authorization": f"Bearer {token}"}
)

Component-Specific Timeouts

{
  "timeout_config": {
    "llm_components": 60000,
    "file_processing": 120000,
    "api_requests": 30000,
    "webhook_delivery": 15000
  }
}

Network Diagnostics

# Test connectivity
ping api.broxi.ai

# Check DNS resolution
nslookup api.broxi.ai

# Test SSL connection
openssl s_client -connect api.broxi.ai:443 -servername api.broxi.ai

# Trace route
traceroute api.broxi.ai

Connectivity Issues

Problem: Cannot connect to API endpoints

Solutions:

Network Configuration
- Check firewall settings
- Verify proxy configuration
- Ensure outbound HTTPS (443) is allowed
- Check corporate network restrictions

DNS Issues

# Test DNS resolution
dig api.broxi.ai

# Try alternative DNS
dig @8.8.8.8 api.broxi.ai

# Check hosts file
cat /etc/hosts | grep broxi

SSL/TLS Issues

# Check SSL certificate
curl -vI https://api.broxi.ai

# Test with specific TLS version
curl --tlsv1.2 -I https://api.broxi.ai

Third-Party API Integration Issues

OpenAI API Issues

Problem: OpenAI integration failing

Solutions:

API Key Validation

# Test OpenAI API key
curl -H "Authorization: Bearer $OPENAI_API_KEY" \
     "https://api.openai.com/v1/models"

Common OpenAI Errors
- Invalid API Key: Check key format and permissions
- Quota Exceeded: Monitor usage and upgrade plan
- Model Not Available: Use supported models
- Content Filter: Review input for policy violations

Configuration Example

{
  "openai_config": {
    "api_key": "sk-...",
    "organization": "org-...",
    "model": "gpt-4",
    "max_tokens": 1000,
    "temperature": 0.7,
    "timeout": 60
  }
}

Google Cloud API Issues

Problem: Google Cloud services integration failing

Solutions:

Service Account Setup

{
  "google_credentials": {
    "type": "service_account",
    "project_id": "your-project-id",
    "private_key_id": "...",
    "private_key": "-----BEGIN PRIVATE KEY-----\n...",
    "client_email": "service@project.iam.gserviceaccount.com"
  }
}

API Enable Check

# Check enabled APIs
gcloud services list --enabled --project=YOUR_PROJECT_ID

# Enable required APIs
gcloud services enable aiplatform.googleapis.com

Azure API Issues

Problem: Azure services integration failing

Solutions:

Authentication Setup

from azure.identity import DefaultAzureCredential
from azure.cognitiveservices.language.textanalytics import TextAnalyticsClient

credential = DefaultAzureCredential()
client = TextAnalyticsClient(
    endpoint="https://your-resource.cognitiveservices.azure.com/",
    credential=credential
)

Common Azure Errors
- 401 Unauthorized: Check authentication credentials
- 403 Forbidden: Verify resource permissions
- 404 Not Found: Check endpoint URLs
- 429 Too Many Requests: Implement rate limiting

Webhook Integration Issues

Webhook Delivery Failures

Problem: Webhooks not being delivered or received

Solutions:

Endpoint Validation

# Test webhook endpoint
curl -X POST "https://your-domain.com/webhook" \
     -H "Content-Type: application/json" \
     -d '{"test": "payload"}'

Webhook Configuration

{
  "webhook_config": {
    "url": "https://your-domain.com/webhook",
    "secret": "your-secret-key",
    "events": ["workflow.completed", "workflow.failed"],
    "retry_count": 3,
    "timeout": 10000
  }
}

Security Validation

import hmac
import hashlib

def verify_webhook_signature(payload: str, signature: str, secret: str) -> bool:
    expected_signature = hmac.new(
        secret.encode('utf-8'),
        payload.encode('utf-8'),
        hashlib.sha256
    ).hexdigest()
    
    return hmac.compare_digest(f"sha256={expected_signature}", signature)

Webhook Debugging

Common Issues:

SSL Certificate Problems: Ensure valid SSL certificate
Response Timeouts: Return 200 status quickly
Authentication Failures: Verify signature validation
Payload Size: Check for size limits

Debug Tools:

# Test webhook locally with ngrok
ngrok http 3000

# Monitor webhook deliveries
tail -f /var/log/nginx/access.log | grep webhook

API Response Issues

Malformed Responses

Problem: API returning unexpected or malformed responses

Solutions:

Response Validation

import json
from jsonschema import validate, ValidationError

def validate_api_response(response_data, expected_schema):
    try:
        validate(instance=response_data, schema=expected_schema)
        return True
    except ValidationError as e:
        print(f"Response validation failed: {e.message}")
        return False

# Example schema
workflow_schema = {
    "type": "object",
    "properties": {
        "id": {"type": "string"},
        "status": {"type": "string", "enum": ["running", "completed", "failed"]},
        "result": {"type": "object"}
    },
    "required": ["id", "status"]
}

Content-Type Handling

# Check response content type
response = requests.get(url)

if response.headers.get('content-type') == 'application/json':
    data = response.json()
else:
    print(f"Unexpected content type: {response.headers.get('content-type')}")

Empty or Missing Responses

Problem: API returning empty responses or missing data

Solutions:

Response Checking

def safe_api_call(url, **kwargs):
    try:
        response = requests.get(url, **kwargs)
        response.raise_for_status()
        
        if not response.content:
            raise ValueError("Empty response received")
        
        return response.json()
    except requests.exceptions.RequestException as e:
        print(f"Request failed: {e}")
        return None
    except json.JSONDecodeError as e:
        print(f"Invalid JSON response: {e}")
        return None

Performance Optimization

Caching Strategies

Implementation:

import redis
import json
from functools import wraps

# Redis cache
cache = redis.Redis(host='localhost', port=6379, db=0)

def cache_api_response(expiration=3600):
    def decorator(func):
        @wraps(func)
        def wrapper(*args, **kwargs):
            # Create cache key
            cache_key = f"api_cache:{func.__name__}:{hash(str(args) + str(kwargs))}"
            
            # Try to get from cache
            cached_result = cache.get(cache_key)
            if cached_result:
                return json.loads(cached_result)
            
            # Call API and cache result
            result = func(*args, **kwargs)
            cache.setex(cache_key, expiration, json.dumps(result))
            return result
        
        return wrapper
    return decorator

@cache_api_response(expiration=1800)
def get_model_response(prompt):
    # Expensive API call
    return openai_client.chat.completions.create(...)

Batch Processing

Example:

async def batch_process_requests(requests_batch):
    """Process multiple API requests in parallel"""
    async with aiohttp.ClientSession() as session:
        tasks = []
        for request in requests_batch:
            task = asyncio.create_task(
                make_api_request(session, request)
            )
            tasks.append(task)
        
        results = await asyncio.gather(*tasks, return_exceptions=True)
        return results

# Usage
batch_size = 10
requests = [{"prompt": f"Question {i}"} for i in range(100)]

for i in range(0, len(requests), batch_size):
    batch = requests[i:i + batch_size]
    results = await batch_process_requests(batch)

Monitoring and Alerting

API Health Monitoring

Setup Monitoring:

import time
import logging
from datadog import DogStatsdClient

statsd = DogStatsdClient(host='localhost', port=8125)

def monitor_api_call(func):
    @wraps(func)
    def wrapper(*args, **kwargs):
        start_time = time.time()
        
        try:
            result = func(*args, **kwargs)
            statsd.increment('api.calls.success')
            return result
        except Exception as e:
            statsd.increment('api.calls.error')
            logging.error(f"API call failed: {e}")
            raise
        finally:
            duration = time.time() - start_time
            statsd.timing('api.calls.duration', duration * 1000)
    
    return wrapper

Error Rate Monitoring

Alert Thresholds:

Error rate > 5% for 5 minutes
Response time > 10 seconds
Rate limit approaching (>80% of limit)
