Update Property Value based on File Upload

[CSYamashiro]

In order to send emails dynamically changing a logo image in the email header, we have a HTML code that shows the logo image based on a contact property called “Dynamic Logo”.

How can I insert the desired image URL in this property in an automated way without having to update it via CSV?

Hi @CSYamashiro,

If you want to update the value of a contact’s property, there are various ways:

• Manually: Edit a property value for a record
• In bulk: Bulk edit records
• Via API: 2026-03 API reference - HubSpot docs
• Via iPaaS, such as Zapier: Use HubSpot's integration with Zapier

Best regards!
