Creates or updates a CRM company record using a unique attribute to find an existing match.
  • If a company with the same domain is found → it is updated and 200 is returned.
  • If no match is found → a new company is created and 201 is returned.

​
Matching attribute

The matchingAttribute query parameter specifies which field to use for the lookup. Currently only domain is supported, as it is the only unique attribute on companies. 
PUT /v2/crm/companies?matchingAttribute=domain

​
Use case

Assert is the recommended endpoint for bulk imports and sync jobs. Send your full company payload and let the API decide whether to create or update — no need to pre-check for duplicates.

  "websiteUrl": "https://acme.com",
  "primaryLocation": "Berlin, Germany",
