Fetch contact custom properties via HubSpot API

[Paigen11]

Hello!

I'd like to know if it's possible to fetch custom properties on a contact via the HubSpot API? I've been trying out the CRM endpoint: https://api.hubapi.com/crm/v3/objects/contacts/{{contact_id}}?hapikey={{ hubspot_api_key }}

But it's only returning me default properties including created date, email, firstname, etc. but I'm looking for a custom property named engagement_score.

Perhaps there's an API endpoint that better serves this purpose? Or there's a query param filter I can add to include these custom properties?

Please advise.

Thanks,

Paige

Hi @Paigen11 ,

If you want to retrieve specific properties, you need to pass them as URL params, so like this:
https://api.hubapi.com/crm/v3/objects/contacts/?properties=engagement_score&properties=lastname
