PATCH
Update customer
The Update Customer endpoint applies a partial update (RFC 7396 JSON Merge Patch) to an existing business company. Send only the fields you want to change; omitted fields keep their persisted values. For more information on how versioning works and how to include it in your requests, please refer to the Versioning page. This endpoint uses optimistic concurrency. You must send the customer’s current ETag in an If-Match header. The token is returned on the ETag response header of a GET, and in the body of a create/update response. If the token does not match the current record the request fails with 412 Precondition Failed; refetch with GET to obtain a fresh value and retry.
