In this article, you will find several ways to connect to the CDISC Library programmatically using REST API.
| Note |

Fictitious CDISC Library credentials are used in these example code snippets. Substitute them with the username and password assigned to you. To request a CDISC Library account, visit https://www.cdisc.org/cdisc-library/api-account-request. |
Python
The objective is to obtain a list of CDISC Controlled Terminology that are loaded into the metadata repository. Two libraries you will need to make a REST API request and store the JSON output:

A REST API GET operation is basically a URL with three parts: base URL, endpoint, path.

You may also specify the output format (or, media type). For JSON, you will specify to accept application/json in the request header:

SAS
Below is a sample program to also obtain a list of CDISC Controlled Terminology. This program is compatible with v9.4 and SAS OnDemand for Academics. For further reading about PROC HTTP, visit on-line documentation at https://documentation.sas.com/?docsetId=proc&docsetVersion=9.4&docsetTarget=n1tv5bhcqw9q4ln1btjqicqdqws3.htm&locale=en. Example 9 discusses how to specify HEADER statements for a GET operation. For creating access to SAS OnDemand for Academics, visit https://www.sas.com/en_us/software/on-demand-for-academics.htm.
