When I use a web browser to access CDISC Library API, I receive an access denied message. Is there a workaround?


Generally speaking, API testing software such as Postman, cURL, etc. is preferable to web browsers for accessing the CDISC Library API.

With CDISC having switched from Basic Auth (i.e., username & password) to API Key Auth for making API requests, an API key must be inserted into each request’s header. Not all web browsers support this operation and, when they do, request header editing may be doable through what’s commonly referred to as Network within Developer Tools. Note that not all Developer Tools are implemented the same, hence we cannot delve into specific steps. Lastly, third party add-ons (or extensions) may address this need by providing a specific UI or means to review and edit request headers.
