Update Company

patch/v1/companies/{company_id}

Updates a company's attributes and/or relationship sets. Only the supplied attributes change; passing null to a nullable attribute clears it. Relationship arrays passed as null detach all current links of that kind. Side effect: writes the company row and reconciles the named relationship junctions.

Requires a bearer token: Authorization: Bearer <token>.

Path parameters

company_id	string <uuid>	Yes	Public UUID of the company.e.g. b2c3d4e5-6f70-4812-93a4-b5c6d7e8f9a0
