API Samples in Postman

Import these Postman collection files to see examples of how the UMLS API works:

You will need the Chrome postman application to interact with these examples.

For help with making authentication calls using Postman, see our tutorial: UMLS REST API: Authentication and Calling.

* The authentication collection is needed to generate service tickets, which are required to run the calls in the rest of the collections.
Running the examples requires a UMLS username and password (or an api key) - apply for a license today!
