HubSpot custom contact properties not appearing in n8n HubSpot node

Describe the problem/error/question

Hi everyone,
I’m building an AI lead qualification workflow in n8n and I’m having an issue with the HubSpot node.
My workflow is:
Website Form
→ Webhook
→ Message a Model
→ IF nodes
→ HubSpot
The AI analyzes the lead and gives me a score from 0–100. I then use IF nodes to classify the lead as HOT, WARM, or COLD.
I connected my HubSpot account to n8n using a HubSpot Service Key / Access Token.
In HubSpot, I created these custom Contact properties:
Lead Category
Lead Score
Requested Service
Budget
Lead Reason
Customer Message
However, when I open the HubSpot → Contact → Create or Update Contact node in n8n and click Add Property, I cannot find any of these custom properties.
The standard HubSpot contact properties are available, but my newly created custom properties are not showing.
I have already added these scopes to my HubSpot Service Key:
crm.objects.contacts.read
crm.objects.contacts.write
crm.schemas.contacts.read
I also refreshed/reconnected the credential in n8n, but the custom properties still don’t appear.
My questions are:
Is crm.schemas.contacts.read the correct scope for n8n to read custom Contact properties?
Does the HubSpot Service Key work correctly with custom properties in the n8n HubSpot node?
Do I need to use OAuth instead of the Service Key?
Is there another step required to make newly created HubSpot properties appear in n8n?
Could this be an n8n property-loading/cache issue?
Any help would be appreciated. I’m trying to map these custom properties from my n8n workflow into HubSpot.

What is the error message (if any)?

Hi @Syed_Haider_Mehmood Welcome!
Your scopes are correct and the Service Key is fine, neither is the problem. The “Add Property” dropdown on the contact upsert is a hardcoded list of standard HubSpot fields, and one of its entries is “Custom Properties”. Select that, then “Add Custom Property” gives you a “Property Name or ID” dropdown that loads Lead Category, Lead Score and the rest live from your portal.
See this:

you can’t have access to custom properties in free plan of Hubspot. you need a paid plan to have access to it. Try other workarounds like http request.
