Currently, the Hiver public API only exposes endpoints for inboxes and conversations. There is no way to programmatically create or update contact records from an external system.

We need a POST /contacts and PATCH /contacts/{id} endpoint that accepts standard fields (email, first name, last name, phone) as well as custom fields values.

This would allow teams using external CRMs like GoHighLevel, HubSpot, or Salesforce to push contact data into Hiver automatically — keeping agent context up to date without manual entry.

Use case: when a new contact is created in our CRM, a webhook fires and creates the same contact in Hiver with all relevant fields populated. Agents open a conversation and already have full context — no tab switching needed.
