Warning
titleImportant note about API key

Accessing CDISC Library API without an API key will result in HTTP 401 (Access Denied). A message similar to the following will appear in the response payload:

Code Block
{
    "statusCode": 401,
    "message": "Access denied due to missing subscription key. Make sure to include subscription key when making requests to an API."
}
Info

As of 2020-11-11, API access to CDISC Library requires an API key. Previous Basic Auth is no longer supported. Follow these instructions to obtain and test with an API key. 

Please contact the CDISC Library Support (mailto:cdisc_library_support@cdisc.org) when you need assistance.
