​
Associations

Pass a company_id to link the person to an existing company. The company must exist or the request returns an error.

​
Duplicate phone numbers

By default, creating a person with phone numbers that already belong to another person in your team returns a 409 Conflict error. The error response includes the IDs of the existing people so you can update them instead. To create the person anyway, set allow_duplicate_number to true. 
{
  "name": "John",
  "numbers": ["+33612345678"],
  "allow_duplicate_number": true
}
To find the existing person by phone number, use Search people with the phone_number filter.
