API Testing and Validation

Test Your Setup

Basic API Call Test:

curl -X GET "https://api.twitter.com/2/tweets/search/recent?query=hello" \
  -H "Authorization: Bearer YOUR_BEARER_TOKEN"

Expected Response:

{
  "data": [
    {

Rate Limiting and Best Practices

Understanding Rate Limits

Essential Access Limits:

• Tweet lookup: 75 requests per 15 minutes
• User lookup: 75 requests per 15 minutes
• Search tweets: 180 requests per 15 minutes

Elevated Access Limits:

• Higher request limits per endpoint
• Additional concurrent requests
• More endpoints available

Handling Rate Limits

Best Practices:

• Implement exponential backoff
• Cache responses when possible
• Batch requests efficiently
• Monitor usage in developer dashboard

Rate Limit Headers:

x-rate-limit-limit: 75
x-rate-limit-remaining: 74
x-rate-limit-reset: 1635724800

Security Best Practices

Protecting Your Keys

Never Do:

• Commit API keys to public repositories
• Share keys in client side code
• Use keys in URLs or logs
• Store keys in plain text

Always Do:

• Use environment variables
• Implement proper access controls
• Rotate keys regularly
• Monitor usage for anomalies

Environment Variable Setup

For Development:

export TWITTER_API_KEY="your_api_key"
export TWITTER_API_SECRET="your_api_secret"
export TWITTER_ACCESS_TOKEN="your_access_token"
export TWITTER_ACCESS_SECRET="your_access_secret"

Troubleshooting Common Issues

Application Denied

Common Reasons:

• Vague use case description
• Policy violations in past
• Incomplete application
• Suspicious activity patterns

Solutions:

• Rewrite application with specific details
• Review Twitter developer policies
• Wait and reapply with improvements

API Key Not Working

Potential Issues:

• Keys not properly copied
• Wrong authentication method
• Expired or revoked keys
• Account suspension

Debugging Steps:

1. Verify keys are correct and complete
2. Check authentication format
3. Test with simple API call
4. Review account status in dashboard

Rate Limit Exceeded

Solutions:

• Implement proper rate limiting
• Upgrade to higher access level
• Optimize request efficiency
• Use caching where appropriate

API Integration Examples

Python Integration

import tweepy
 
# Authentication
auth = tweepy.OAuthHandler(API_KEY, API_SECRET)
auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)
 
# Create API object
api = tweepy.API(auth)
 
# Post a tweet
api.update_status("Hello Twitter API!")

Node.js Integration

const Twitter = require('twitter');
 
const client = new Twitter({
  consumer_key: process.env.TWITTER_API_KEY,
  consumer_secret: process.env.TWITTER_API_SECRET,
  access_token_key: process.env.TWITTER_ACCESS_TOKEN,
  access_token_secret: process.env.TWITTER_ACCESS_SECRET
});
 
// Search for tweets
client.get('search/tweets', {q: 'social media'}, function(error, tweets, response) {
  console.log(tweets);
});
