CRM API Improvements

Several updates make using these APIs easier and faster. From enriched error messages to property validations, these enhancements help you maintain clean data hygiene and support faster debugging. Improvements to the CRM APIs include:

  • Validating import requests to CRM object records only if the required properties are included. 
  • Allowing users to request the internal property name or property values when using the Exports API instead of only their labels.
  • Limiting the number of associations that can be called with the batch reads endpoints for better performance.
  • Grabbing all labeled, unlabeled, and user-defined associations for records with over 100 associations.
  • Enriching error messages with detailed property validation error information for faster debugging.

These new and improved features make HubSpot’s Smart CRM your single source of truth, seamlessly connecting every part of your business  and intelligently powering your AI processes. Looking to customize the CRM more deeply? Read the latest on UI extensions
