If you have added data that needs to be deleted, for example, if it has been associated with the wrong ORCID iD, then you can make an HTTP DELETE request specifying the relevant endpoint, along with the ORCID iD, stored access token, and stored put code. Only one item can be deleted at a time, and you can only delete items added by your client. You can delete items even when the user has revoked permission.
This example call deletes the employment item with the put code “739288” from a record”
Method: DELETE Content-type: application/vnd.orcid+xml or application/vnd.orcid+json Authorization type and Access token: Bearer [stored access token] URL: https://api.sandbox.orcid.org/v3.0/[ORCID iD]/employment/739288
