HubSpot API Essentials – API Docs, Rate Limits, Integration & More

HubSpot offers a full platform of marketing, sales, customer service, and CRM software. Explore key information to build a HubSpot API or Webhooks integration.

Limitations to HubSpot API

• Rate limits can be restrictive. The standard 100 requests per 10 seconds may bottleneck heavy data operations. Enterprise apps often need custom rate limit agreements.
• Complex object relationships require multiple calls. HubSpot’s API structure means fetching related data (contacts with deals, companies with activities) often requires separate requests, increasing complexity.
• Historical data access is limited. Some endpoints only provide recent data. Bulk historical exports may require specialized tools or manual processes.
• Custom property sync delays. Changes to custom properties and complex workflows can take time to reflect in API responses, affecting real-time integrations.
