HubSpot Developer Policy

Last updated:

Thank you for choosing to develop on the HubSpot platform. Our goal is to provide an ecosystem where Customers and developers can easily build, deploy, and grow their business through a wide range of tools, integrations, websites, plugins, modules, etc that connect to their HubSpot Accounts. Developers are required to comply with this HubSpot Developer Policy (this “Policy”), our Developer Terms and our Acceptable Use Policy (“AUP”). All capitalized terms used in this Policy are the same as those in the Developer Terms.

We’re focused on providing a secure, high-quality, and data protection and privacy-focused environment for Customers), and this policy outlines our expectations for all of our developers. This policy may not cover every type of Application or Integration, and there may be instances where your Application and/or Integration is not addressed by this Policy. We reserve the right to take any action or steps necessary we deem necessary if your Application and/or Integration violates the terms or spirit of this policy, or we feel that such action is necessary to preserve the integrity of our Developer ecosystem or to protect Customers.

Violations of this Developer Policy may result in your Application and/or Integration (as defined in the Developer Terms) being blocked from connecting to the HubSpot Platform. We reserve the right to make changes to this Policy with or without notification to you.

If you have questions about this Policy or our Developer ecosystem please contact HubSpot Support.

A. Data Protection.

We take Data Protection very seriously at HubSpot and expect a high standard from our Developers.  We expect that you will comply with all applicable laws and regulations. As such we have the following guidelines for data protection and privacy standards:

  1. You will not create Applications and/or Integrations which violate the applicable data protection laws and regulations.
  2. You will not create Applications and/or Integrations which enable Customers to circumvent or violate the HubSpot Terms of Service, Developer Terms, Customer Data Processing Agreement (DPA), and/or AUP.
  3. You will not create Applications and/or Integrations which enable Customers to circumvent or violate the terms or policies of other platforms, applications, integrations, or any entity that has a relationship with the Customer. 
  4. You will not sell, rent, exploit, or distribute HubSpot Customer Data without express consent from the Customer.
  5. Your Application and/or Integration should clearly explain your data privacy practices, and be prepared to tell Users how you plan to use the data that is being shared. This detail should be included in an easily accessible privacy policy which explains to Customers how their data will be collected, used, and processed and what control Users have over their data.
  6. Your Application and/or Integration should not collect, store, and/or use personal data (meaning any information relating to an identified or identifiable natural person) without the consent of the data subject or a lawful basis to collect, store, or use such information.
  7. If your Application and/or Integration stores the personal data for a Customer and the Customer requests for their data or Content to be erased, you must erase their data and/or Content.
  8. If your Application and/or Integration stores the personal data for a Customer and the Customer modifies their data, you must either erase or update the data.
