What Are the Differences in GoHighLevel API Access Levels?
GoHighLevel provides different levels of API access depending on your subscription plan. Understanding these distinctions is critical because they determine which API endpoints you can use, the type of authentication keys available, and the scope of your integrations. Matching your development needs with your plan's capabilities prevents unexpected limitations.
1
Identify Basic API Access — If you are on a Starter or Unlimited GoHighLevel plan, you have Basic API access. This level typically includes Location API Keys, which grant access to data and actions within a single specific location. Basic access supports a wide range of common integrations for individual businesses.
2
Recognize Advanced API Access — The Agency Pro plan unlocks Advanced API access. This tier provides greater flexibility and power, including the ability to use Agency API Keys. Agency Keys allow you to manage multiple locations or sub-accounts from a single integration, ideal for white-label agencies.
3
Understand OAuth 2.0 Availability — Advanced API access on the Agency Pro plan also enables the use of OAuth 2.0. OAuth 2.0 is crucial for building public applications or Marketplace apps that require secure, user-approved access to multiple GoHighLevel accounts. It provides a robust authentication flow, essential for broader distribution and enhanced security.
✅ Before starting any complex API integration, verify your GoHighLevel plan level. This ensures you have the necessary API access (Basic vs. Advanced) and the correct key types (Location vs. Agency, or OAuth 2.0) to achieve your project's goals without unforeseen limitations.
How Do GoHighLevel API Rate Limits Work?
GoHighLevel implements API rate limits to maintain system stability, ensure fair resource distribution, and protect against abuse. These limits dictate how many API requests your application can make within a specific timeframe. Understanding and respecting these limits is paramount for building reliable integrations that do not experience unexpected errors or service interruptions.
1
Understand Burst Limits — GoHighLevel applies a burst limit of 100 API requests per 10 seconds. This limit is set per Marketplace app (client) per resource (Location or Company). Design your applications to handle this burst limit gracefully, implementing delays or queues if necessary.
2
Recognize Daily Limits — You also face a daily limit of 200,000 API requests per day. This limit applies per Marketplace app (client) per resource (Location or Company). Plan your data synchronization and batch processes accordingly to stay within this daily allowance.
3
Monitor Your Usage with Response Headers — GoHighLevel includes specific headers in every API response to help you track your current rate limit usage. These headers provide real-time data on your remaining requests and the reset intervals. Regularly check these headers to proactively manage your API calls.
4
Interpret Rate Limit Headers — Look for `X-RateLimit-Limit-Daily`, `X-RateLimit-Daily-Remaining`, `X-RateLimit-Interval-Milliseconds`, `X-RateLimit-Max`, and `X-RateLimit-Remaining` in your API responses. Implement logic in your application to read and respond to these headers, such as pausing or retrying requests with exponential backoff.
⚠️ Exceeding GoHighLevel's API rate limits can result in temporary or permanent blocking of your API access. This disrupts your integrations and severely impacts your business operations. Always design your applications with rate limits in mind and implement robust error handling for `429 Too Many Requests` responses.
🔥 Pro Tip
Implement an exponential backoff strategy in your API integration. If you receive a rate limit error, wait for a short period before retrying, increasing the wait time with each subsequent failure. This prevents your application from continuously hammering the API and getting permanently blocked.
