Create an object
Creates a new object of the specified type.
For contacts and companies, the system automatically deduplicates:
- Contacts are matched by email — if a contact with the same email exists, it will be updated instead.
- Companies are matched by domain, LinkedIn URL, or name similarity.
Custom objects are always created as new records.

Path Parameters
The object type slug. Use contacts for People, companies for Companies,
or the slug of a Custom Object (e.g., deals, tickets).
Singular forms (contact, company) are also accepted.
Body
Display name for the object
"Alex Johnson"
Key-value pairs of fields to set on the object
{
"email": "alex@acme.com",
"role": "Engineer",
"industry": "Technology",
"custom_score": 95
}
Avatar URL (contacts) or logo URL (companies)
Response
Object created
A flat object containing all fields. System fields (name, email, phone, etc.) and
custom fields are merged into a single level — the custom_fields JSON column is
flattened so every field is a top-level key.
