Rate Limits & Quotas

Understand the rate limits and quotas for Trello API access.

300

Requests / Minute

Requests / Day

Important Notes

•Trello API has a rate limit of 300 requests per 10 seconds (approximately 1,800 requests per minute when sustained)
•The primary rate limit is based on 10-second windows: 300 requests per 10 seconds per API key
•No specific daily limit is enforced, but applications should implement exponential backoff for 429 responses
•Rate limits apply per API key and per application token
•Higher rate limits may be available for enterprise customers upon request

Best Practices

1.
Implement exponential backoff
When you receive a 429 error, wait before retrying with increasing delays.
2.
Cache responses when possible
Store frequently accessed data locally to reduce API calls.
3.
Use batch operations
Combine multiple operations into single requests where supported.
4.
Monitor your usage
Use the Primrose dashboard to track your API usage and set alerts.

Rate Limit Errors

What happens when you exceed limits

{
  "error": {
    "code": "rate_limit_exceeded",
    "message": "Too many requests",
    "retry_after": 60
  }
}

When rate limited, the response includes a retry_after value indicating how many seconds to wait before retrying.
