To ensure reliable service and fair usage for all customers, we implement rate limits that control how many API requests you can make within a specific time period. Rate limits prevent any single user from overwhelming our servers and help maintain consistent performance across our platform. ## Tier limits Rate limits are applied per `api_token` - the unique authentication key that identifies your Document360 account when making API calls. Each subscription tier has different rate limit allowances based on your plan's features and capacity. **Rate limits by subscription tier** | Plan tier | Rate limit | | --- | --- | | Standard | API access is not available | | Professional, Business | 60 requests per minute per `api_token` | | Enterprise, Enterprise Plus, & Trial | 100 requests per minute per `api_token` | > [!NOTE] > NOTE > > If you've exhausted your limits, you can restructure your integrations or upgrade to a higher tier. If your integrations regularly exceed the limit, consider optimizing request frequency using caching or batching strategies. --- ## Header information Every API response includes headers that help you monitor your usage: - **X-RateLimit-Limit:** The maximum number of requests that can be made by the current `api_token` - **X-RateLimit-Remaining:** The remaining number of calls within the time window - **X-RateLimit-Reset:** The number of seconds before the limit is reset Once you exhaust the request limit, any concurrent API call will return an error response with an **HTTP code 429**. You can refer back to the **X-RateLimit-Remaining** header, which will inform you when the limit will reset. > [!NOTE] > NOTE > > By default, only the `X-RateLimit-Remaining` header is included in each response. Once the limit is reached, `X-RateLimit-Limit` and `X-RateLimit-Reset` headers are also included. --- ### FAQs #### What counts as a request? Each API call you make (GET, POST, PUT, DELETE) counts as one request toward your limit. This includes retrieving articles, creating content, updating categories, or any other API operation. #### What are the best practices for managing rate limits? 1. Monitor your usage Always check the `X-RateLimit-Remaining` header in your responses to track how many requests you have left. 2. Implement rate limit handling Build error handling into your code to manage 429 responses gracefully. 3. Optimize your requests - **Use caching**: Store frequently accessed data locally to reduce API calls - **Batch operations**: Combine multiple updates into a single request when possible - **Paginate efficiently**: Use appropriate page sizes when retrieving large datasets - **Schedule non-urgent tasks**: Spread out bulk operations over time 1. Choose the right approach - For real-time applications: Monitor headers closely and implement retry logic - For bulk operations: Use smaller batches with delays between requests - For periodic syncing: Schedule operations during off-peak hours #### What to do when you regularly exceed limits? **Immediate solutions:** 1. Restructure your integrations: Optimize your code to make fewer API calls 2. Implement caching: Store data locally to reduce repeated requests 3. Add delays: Space out your API calls to stay within limits **Long-term solutions:** 1. Upgrade your tier: Higher-tier plans offer increased rate limits 2.
