Contacts

Create a Contact

Creates a new contact.

Identifiers — either email or linkedin_url must be provided. If only linkedin_url is supplied, you must also provide account_id or domain so the contact can be associated with an account.

Account resolution priority — Monaco resolves the contact's account in this order:

  1. account_id (if provided)
  2. domain (if provided)
  3. the domain parsed from email

Enrichment — on creation, Monaco synchronously enriches the contact (name, title, company association, etc.) and, if needed, resolves or creates the associated account. This can make create requests take several seconds to complete; clients should use generous timeouts (10s+) and avoid issuing creates on hot paths.
