Hi,

How can I include or convert a property as unique key in the custom objects?. I need to avoid a duplicate records in the custom object and I don’t know how can I do this.

Can I do something like the “Email” property in the “Contact” object?. The HubSpot don’t allow to include two contact with the same email.

Thanks in advanced,

Kale

Hi, @kaleperez 👋 I think this one will come down to, _it depends…_ Can you tell the community a bit more about your goal?

Are you needing a unique idenditfier for your custom object _only_ for doing imports? In the past you were limited to record ID, but there was a public beta released in Dec 2022 that added new functionality.

Here are some links to get you started:

- [Unique identifier — Custom unique value property](https://knowledge.hubspot.com/crm-setup/set-up-your-import-file#file-requirements:~:text=Custom%20unique%20value%20property)
- [Custom unique value property](https://knowledge.hubspot.com/crm-setup/import-objects#:~:text=Custom%20unique%20value%20property)

You can find the full beta details in your portal by doing the following:

- Click the account dropdown in the upper right hand side of your portal
- Click Product Updates
- Change the date range to _last year_ (as this update was from 12/2022)
- Search for _unique_

If this is not what you are after, please add more details.

Have fun building!

Thanks Jaycee,

How I can include as unique values an existing property?. In HS says that I can’t, but there is any way that I can do this, I don’t know, using the API.

I used this property in multiple steps, workflow, APIs and created a new property with the same information could be very complicated.

Thanks,

Kale
