Is it possible to edit a contact property that was created by HubSpot (Became a Customer Date) via API?

Hi @eklimara,

The ‘Became a Customer Date’ property is read-only, and can’t be edited via the API. This is also true for other read-only properties like ‘Create Date’ and ‘Original Source.’ Other HubSpot-created properties that aren’t read-only, like ‘Email’ and ‘First Name,’ can be edited both via the API and in-app.
