The following steps will walk you through how to upload an application to the OCLC WorldShare App Gallery. These steps apply for both click-to-install apps and other applications.
Are you affiliated with an OCLC member library?
Logging into the Platform App Tool requires you to login through your institution. You will need to construct a URL in the following form:
https://{institution-prefix}.platform.worldcat.org/platformprofile
where the {institution-prefix} matches URL prefix used by your institution for OCLC's WorldShare Management System (WMS) applications.
If you aren’t affiliated with an institution that is uses WMS, use the following URL:
https://ocpna.platform.worldcat.org/platformprofile
You will be redirect to the appropriate screen to login.
Apps are tested for basic metadata as part of this process.
Apps that lack basic metadata will produce an error message detailing the missing fields.


Once an app is uploaded, a developer can test the it in the Developer Sandbox and then Request Certification.
