What does a webhook callback look like?

The ORCID Registry will do the following HTTP call when a record is updated. The request uses the HTTP POST method, but the body of the request is empty.

curl -v -X POST https://nowhere2.com/0000-0002-7253-3645/updated

Your server should respond with standard HTTP response codes. So, if the call was successful you should return 204 No Content.

HTTP/1.1 204 No Content

Any 2xx response code means that the call was successful. If you return a code that is not a 2xx, then we will retry the call five minutes later.
