How to Utilize the Unpaywall API for Open Access Content and Resources in Discovery

Unpaywall is a Database of Open Access Content that maintains links to full text articles and Open Access resources.
The Unpaywall API allows for retrieving the metadata associated with these full text articles and resources.

The response from the Unpaywall API must meet the following conditions for a Unpaywall Service to display:

I. The response should have a "best_oa_location" specified in the response

II. The 'url_for_pdf' field under the "best_oa_location" must have a value.

III. The response must also include the "is_best" value = true.

Unpaywall is a third party Database. There may be occasional instances of incorrect links or links to non-Open Access content.
If Primo (using https) displays a "Get PDF" link from Unpaywall that uses http, the browser may refuse to open the link because the browser thinks the action of https Primo opening a less secure http link is risky behavior. If this occurs, as an alternative, try manually copying the Get PDF link address and pasting it in a new browser tab or window.
