Rate Limits

The server includes built-in rate limiting matching GHL's limits:

• Burst: 100 requests per 10 seconds

• Daily: 200,000 requests per day

The server automatically queues and retries when limits are approached.

Error Handling

All tools return actionable error messages with hints:

• 401: Check your API key (must be Private Integration Token)

• 403: Missing scopes — edit your Private Integration in GHL Settings

• 404: Resource not found — check the ID

• 422: Validation error with details

• 429: Rate limit — automatic retry
