Unable to add CRM property to show in Contacts object

I’m trying to use the below code to update the “Title” CRM property in contacts object. But it just does not work.

_hsq.push(["identify", {
 email: 'hello@test.com',
 Title: 'Test'
}]);

I have gone to Settings > Properties and created a property called “Title” in Hubspot which is a single-text field type (string).

The above ode creates a contact with the email hello@test.com, but it does not populate the Title property.

I’ve tried all small things that have come to my head to get this to work, but it just does not.

@ansh1709 Can you check that you are correctly using the Internal Name? Unless you specifically edited the Internal Name (not just the Property Label) these would normally default to lowercase.

_hsq.push(["identify", {
 email: 'hello@test.com',
 title: 'Test'
}]);
