Hi @PabloOsorio 👋

You’ve rightly pointed out [the documentation](https://developers.hubspot.com/docs/guides/api/crm/objects/contacts#secondary-emails) needs to be updated. It currently states:

_To add secondary emails to a contact, when creating or editing the contact, in your request body, include emails in the hs\_additional\_emails field. Multiple emails can be separated by a semi-colon._

Given this property is “read only” (i.e. modificationMetadata.readOnlyValue = true), updating it via the relevant API V3 endpoints is not possible. As far as I know, [the V1 endpoints](https://developers.hubspot.com/docs/reference/api/crm/objects/contacts/v1#add-a-secondary-email-address) are still operational, so I think you’ll have to use them for now.

I hope this proves helpful. Please let me know if you have any follow-up questions.
