# Best Practices

Tips for getting the most out of Synter

## API Key Security

Use environment variables

Store API keys in environment variables, never in code

Rotate keys regularly

Generate new keys periodically and revoke old ones

Never commit keys to git

Add .env files to .gitignore

Don't expose in client-side code

Make API calls from your server, not the browser

## Rate Limits

100

Requests per minute

10,000

Requests per day

Implement exponential backoff

When you receive a 429 status, wait and retry: 1s, 2s, 4s, 8s...

## Efficient Credit Usage

### Batch operations

Use list operations instead of individual gets

### Cache responses

Store campaign lists locally, refresh hourly

### Use free tools first

get\_credit\_balance and get\_connection\_status are free

### Avoid redundant calls

Check if data changed before pulling again

## Free tools (0 credits)

| Tool | Description |

| get_credit_balance | Check your remaining credits |
| get_connection_status | Verify which platforms are connected |
