On September 20th 2021 we will be introducing the following property limits to the Custom Behavioural Events API which is currently in beta.
If these limits are exceeded when making an HTTP API request, the request will fail and we will return a detailed error message to let you know which limit was exceeded. If these limits are exceeded when making a JS API request, HubSpot will truncate any property name values to the allowed length and/or update only 50 properties per event completion.
The new limits will be introduced on September 20th 2021. Please let us know if you have any questions by replying below.
