Critical HubSpot API Update: Preparing for Stricter Data Validation

On April 7, 2025, HubSpot will implement stricter validations for non-string property values, a seemingly minor technical change that could significantly impact your business operations if you're using the HubSpot API.

Understanding the Change and Its Impact

HubSpot's upcoming API update introduces more stringent validation requirements that will affect how your systems interact with the platform. While this change might appear technical in nature, it has real operational implications for businesses relying on HubSpot integrations.

Currently, HubSpot accepts values with extra spaces (like " two "). After April 7, only clean values without trailing or leading spaces (like "two") will be accepted. Any data containing extra spaces or invisible Unicode characters will be rejected with 400 Bad Request errors, potentially causing cascading failures across your technology stack.

This is precisely the type of subtle technical change that can create significant disruptions when it surfaces unexpectedly in production environments.

Why This Matters for Your Business

For organizations using the HubSpot API, this update represents a critical consideration for several reasons:‍

• Integration Stability: Existing integrations that don't properly sanitize data may suddenly fail
• Data consistency: Rejected records could create inconsistencies between systems
• Operational Continuity: Unexpected failures could disrupt critical business processes
• Resource allocation: Emergency fixes require diverting technical resources from planned initiatives

The impact extends beyond just technical considerations. Customer data management, marketing automation, sales processes, and reporting could all be affected if your integrations aren't prepared for this change.

Preparing for the Change

If you're not currently using Stacksync, it's crucial to plan for this change now to prevent disruptions to your business operations:
