Introduction
In this article, you will find several ways to connect to the CDISC Library programmatically using REST API.
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:XML is an alternate output format you may specify:Link to download the full script: https://bitbucket.cdisc.org/snippets/1cf26161a1b640daad885dd57295e4c2/download.
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.

Java
Below is a basic CDISC Library client in Java. This example client, by Jozef Aerts, demonstrates how to get started creating a CDISC Library REST client in Java.Link to download this code snippet: https://bitbucket.cdisc.org/snippets/c81ab9b9e133420e80510465e234f533/download.
R
Below is a basic CDISC Library client in R, tested using R Studio v1.2.5 with R v3.6. This example demonstrates how to obtain a product catalog using the /mdr/products endpoint.Link to download this code snippet: https://bitbucket.cdisc.org/snippets/f6589a6c6f7d41239ea6ef0e8be0ce1e/download.
XQuery
Below demonstrates how to request a quarter of SEND CT from CDISC Library using XQuery. For technical overview about XQuery, visit https://www.w3.org/TR/xquery/all/.Link to download this code snippet: https://bitbucket.cdisc.org/snippets/9e2db509e6ab43f7a3ac82f06a7aae53/download.
Also available is a Java program that incorporates this XQuery method: https://bitbucket.cdisc.org/snippets/5b4e4100c52b4fb2ac633f83d04a4251.
