+
+If the request succeeds, you'll get an HTTP 204 response, which represents that you have successfully updated the contact in the system. There will be no data in the response body.

+#### - Create or update a contact
+Create a contact if it doesn't exist already, or update it with the latest property values if it does.
+
+This returns a 200 response on success. The response will contain a vid of the updated or created record, and an isNew field that indicates if a new record was created. If the field is false, an existing record was updated.
+
+This will return a 409 Conflict error response if you are trying to update the email address of a record, and there is an existing record with the new email address.
+
+**Usage:**
+```javascript
+api.contacts.createOrUpdateContact({
+  firstname: 'Jon',
+  lastname: 'Doe',
+  website: 'http://www.my-new-company.com',
+  company: 'My Company 2',
+  ...
