HubSpot is changing how validation works on some commonly used fields for contacts, including the first and last name. This change will look for values that are obviously not valid values for the fields.
Why are we making this change?
This change should help HubSpot customers maintain a cleaner database by rejecting obviously wrong values from being added to properties. This change is also designed to help protect customers from attack. By restricting the values of commonly used fields, it makes it more difficult for attackers to inject potentially harmful values.
What action is required?
For the vast majority of developers, no action is required. However if you are using the default fields for a purpose other than their original intent, you should create a custom property to hold this information.
When will this change take place?
This change will take effect on February 26, 2020.
