Update
Updating a record is accomplished by sending a HTTP PUT to the appropriate URL. The form of the URL requires knowledge of the record ID being updated. If the record ID is not known, then it must be looked up using the list action. The payload of the PUT needs to only contain the fields that are to be changed. The contents of the payload must meet the model requirements otherwise an error will be thrown. Consider the following example where the first name associated with account ID 36 is being updated via XML:
curl -i -X PUT -H 'Content-Type: application/xml'
-d '<?xml version="1.0"?><record><first-name>Alfred</first-name></record>'
https://rxg.dns/admin/scaffolds/accounts/update/36.xml?api_key=WR5...KLw
or via JSON:
curl -i -X PUT -H 'Content-Type: application/json'
-d '{"record": {"first_name": "Anson"}}'
https://rxg.dns/admin/scaffolds/accounts/update/36.xml?api_key=WR5...KLw
If the request is successful the rXg responds with a HTTP/1.1 200 OK:
```

If the request fails, then the rXg responds with an HTTP error code, usually HTTP/1.1 422. For, example, if an invalid first name is passed in:
curl -i -X PUT -H 'Content-Type: application/xml'
-d '<?xml version="1.0"?>
The response would be:
HTTP/1.1 422
