Using the MCommunityUidNumber API (Web Service)

This document provides information about the MCommunityUidNumber application programming interface (API). The MCommunityUidNumber API is a web service that IT professionals can use to reserve uid numbers for accounts. Instructions on making a request, available input parameters, and potential outputs and definitions are detailed in this document. This document assumes a basic understanding of the U-M API Directory. See the Help page on the API Directory website for information about the API Directory.

About the API

The MCommunityUidNumber API is a web service that IT professionals can use to reserve uid numbers for administrative accounts. A uid number is used in Unix/Linux systems as a unique identifier for an account. This service enables reservation of uid numbers in a way that avoids overlap with ones assigned by the ITS MCommunity team and others.

The API is restricted to 200 calls per minute. The MCommunityUidNumber API supports JSON (JavaScript Object Notation).

Use the ITS Service Status page to stay informed about potential outages of this web service.

Making a Request

The API is located in the API Directory.

First, join a developer organization using the Getting Started Page of API Directory.

Once you get access to join a developer organization:

  1. Log in to the API Directory with your uniqname and UMICH password.
  2. Register your application with the API Directory by adding it as a new application.
  3. Note the Client Id and Client Secret when you are creating the application as they will be used in getting the access tokens for API access.
  4. On the API Directory site, navigate to the MCommunityUidNumber API by searching for the API in the search box.
  5. Subscribe to the MCommunityUidNumber API by selecting your application in the list.
  6. Use your Client Id and Client Secret obtained in step three to generate an access token either:
    1. Programmatically within your application
    2. Or on the API page for your application

By default, access tokens are available for one hour.

  1. Make a request using the appropriate input parameters. Check the sample request and response listed below.
