To request a WSKey you will need to complete the API application form on the OCLC Developer Network site. Once completed, your WSKey request will be reviewed to make sure you have the requisite subscriptions. If you do, the WSKey will be sent directly to you.
If you would like a sandbox key for the Metadata API, please request a production key and a sandbox key will be included with it.
Businesses with no WorldShare account wanting a WSKey to use APIs should contact busdev@oclc.org with a description of their project to be considered for OCLC's Partner Program.
Unfortunately, we do not provide WSKeys or API access to students or other individuals.
