HubSpot App Certification: Why Staying Updated Isn't Optional Anymore

In the fast-paced world of digital commerce and CRM, staying current with platform updates isn't just a good idea—it's often a necessity. This holds especially true for developers building on the HubSpot ecosystem, and by extension, for the businesses, RevOps teams, and marketers who rely on these apps daily. We recently saw a crucial discussion unfold in the HubSpot Community that sheds light on this very topic: the mandatory nature of app updates for Marketplace certification.

The Dilemma: Old App Version vs. New Requirements

The original poster in the community thread brought up a common concern for many app developers: their app was running on an older version, and updating to the 'latest' at the time (which they suspected was 2025.2) seemed problematic. Specifically, they worried that the newer version wouldn't support calling SDK APIs, potentially breaking core features. Their core question was straightforward: is updating the app version an absolute requirement for Marketplace certification approval?

This isn't a trivial concern. Imagine your app is integral to a client's website builder for online boutique, handling everything from inventory sync to personalized customer journeys. Any update that could destabilize key features, like those relying on SDK APIs, could have serious repercussions for their business operations and customer experience.

Community Insights: Clarity from the Experts

A community manager initially weighed in, confirming that while legacy apps are indeed still supported by HubSpot, creating new apps or updating existing ones on the latest developer platform (2026.03) is 'highly recommended.' This initial response hinted at the direction things were heading but didn't provide the definitive 'yes or no' the original poster was seeking for certification.

However, the real clarity came from a top contributor, who didn't mince words: the short answer is yes, you have to update. But here's the critical nuance that resolved the SDK concern: developers need to jump to version 2026.03, not 2025.2. The 'no SDK API support' gap that worried the original poster was specific to the 2025.2 version. By targeting 2026.03, those SDK-dependent features should function as expected.

Key Takeaways for App Developers and HubSpot Users:

• Mandatory Updates: For any app submitting for certification or recertification, being on a currently supported developer platform version is now a hard requirement. Apps still running on legacy versions or older projects (like 2023.2 / 2025.1) will be rejected during review.
• The Right Version Matters: If you're concerned about SDK API support, target 2026.03. The issues were specific to 2025.2.
• Remediation Window: HubSpot offers roughly a 60-day remediation window if your app gets flagged during the review process, but skipping the update isn't an option.
• OAuth v3 Migration: While you're updating, don't forget another critical requirement: migration to the new OAuth v3 endpoints, applicable for May 2026 requirements. This is crucial for maintaining secure and reliable connections between your app and HubSpot portals.

For businesses relying on these apps, whether it's for managing their bigcommerce transactional emails or syncing customer data across platforms, these developer-level updates are vital. An uncertified or outdated app poses risks to data integrity, security, and overall operational efficiency.

ESHOPMAN Team Comment

This discussion perfectly illustrates the ongoing challenge of platform evolution. At ESHOPMAN, we firmly believe that staying on top of HubSpot's developer platform updates is non-negotiable for app stability and security. Ignoring these requirements not only jeopardizes Marketplace certification but also puts the end-user experience at risk. While these changes can seem daunting for developers, they ultimately lead to a more robust and secure ecosystem for all HubSpot users.

The takeaway here is clear: for developers, keeping your app updated to the latest supported HubSpot developer platform version isn't just about compliance; it's about ensuring your app remains functional, secure, and available to the thousands of HubSpot users who rely on integrated solutions. For HubSpot users, this means you can expect a higher standard of reliability and performance from the apps you choose from the Marketplace, ensuring your e-commerce operations and marketing efforts run smoothly.
