id="authorization-service-api">Authorization Service API</h1> <p>The <a href="https://authorization-service-api.web.cern.ch/swagger/index.html">Authorization Service API</a> is an OAuth2 protected API used by CERN's Identity Management Infrastructure to manage Identities, Groups, Roles, Applications and more. You may also want to use it, for example to:</p> <ul> <li>Query Groups</li> <li>Search for Identities</li> <li>Programmatically create Applications, and Roles</li> </ul> <h2 id="api-endpoints">API Endpoints</h2> <p>You can see all the available API endpoints, and test the Authorization Service API using the <a href="https://authorization-service-api.web.cern.ch/swagger/index.html">Swagger Interface</a> Through the API you can manage different resources such as identities, groups, accounts etc. For more details on the different resources and their attributes check <a href="../model/">here</a>.</p> <h2 id="how-to-use-the-authorization-service-api">How to use the Authorization Service API</h2> <p>For most needs we recommend creating an OIDC client and using your Client Credentials to query the Authorization Service, follow this <a href="../../user-documentation/oidc/api-access/">Guide for API Access</a>. If you want to query the Authorization Service on behalf of a user accessing your own application, i.e. OIDC delegation, follow this <a href="../../user-documentation/oidc/exchange-for-api/">Guide for Token Exchange</a>. The Authorization Service's clientID is <code>authorization-service-api</code>, which should be used as the <code>aud</code> or <code>audience</code> in your requests.</p> <p>Once you have an access token for the Authorization Service, you can include it in the Authorization header of an HTTP request to query the API:</p> <div class="highlight"><pre><span></span><code><span class="c1">### Call the Authorization Service API using your the exchanged token</span> <span class="nv">API_RESPONSE</span><span class="o">=</span><span class="k">$(</span>curl<span class="w"> </span><span class="se">\</span> <span class="w"> </span>-X<span class="w"> </span>GET<span class="w"> </span><span class="s2">&quot;https://authorization-service-api.web.cern.ch/api/v1.0/Identity/my&quot;</span><span class="w"> </span><span class="se">\</span> <span class="w"> </span>-H<span class="w"> </span><span class="s2">&quot;Accept: */*&quot;</span><span class="w"> </span><span class="se">\</span> <span class="w"> </span>-H<span class="w"> </span><span class="s2">&quot;Authorization: Bearer </span><span class="nv">$API_ACCESS_TOKEN</span><span class="s2">&quot;</span><span class="w"> </span><span class="k">)</span> <span class="nb">echo</span><span class="w"> </span><span class="nv">$API_RESPONSE</span> </code></pre></div> <h2 id="querying-with-pagination">Querying with pagination</h2> <p>For the case that you need to query the API to receive back a big amount of entities you'll need to do it with pagination (receive them in chunks).</p> <p>For example let's assume one wants to get back all the groups. This means that they'll need to send a post request to the endpoint <code>https://authorization-service-api.web.cern.ch/api/v1.0/Group</code>.</p> <p>The response they'll receive will contain the following payload: <div class="highlight"><pre><span></span><code><span class="p">{</span> <span class="w"> </span><span class="nt">&quot;pagination&quot;</span><span class="p">:</span><span class="w"> </span><span class="p">{</span> <span class="w"> </span><span class="nt">&quot;total&quot;</span><span class="p">:</span><span class="w"> </span><span class="mi">72272</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;offset&quot;</span><span class="p">:</span><span class="w"> </span><span class="mi">0</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;limit&quot;</span><span class="p">:</span><span class="w"> </span><span class="mi">1000</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;next&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;/api/v1.0/Group?token=eyJJZCI6IjA4ZDc4&amp;limit=1000&quot;</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;links&quot;</span><span class="p">:</span><span class="w"> </span><span class="p">{</span> <span class="w"> </span><span class="nt">&quot;first&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;/api/v1.0/Group?offset=0&amp;limit=1000&quot;</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;previous&quot;</span><span class="p">:</span><span class="w"> </span><span class="kc">null</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;current&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;/api/v1.0/Group?offset=0&amp;limit=1000&quot;</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;next&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;/api/v1.0/Group?offset=1000&amp;limit=1000&quot;</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;last&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;/api/v1.0/Group?offset=72000&amp;limit=1000&quot;</span> <span class="w"> </span><span class="p">},</span> <span class="w"> </span><span class="nt">&quot;token&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;eyJJZCI6IjA4ZDc3OWE2LTE3YjYtOTAzNy01MzQzLTc4&quot;</span> <span class="w"> </span><span class="p">},</span> <span class="w"> </span><span class="nt">&quot;delta&quot;</span><span class="p">:</span><span class="w"> </span><span class="kc">null</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;request_id&quot;</span><span class="p">:</span><span class="w"> </span><span class="kc">null</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;message&quot;</span><span class="p">:</span><span class="w"> </span><span class="kc">null</span><span class="p">,</span> <span class="w"> </span><span class="nt">&quot;data&quot;</span><span class="p">:</span><span class="w"> </span><span class="p">[</span> <span class="w"> </span><span class="p">{</span> <span class="w"> </span><span class="nt">&quot;groupIdentifier&quot;</span><span class="p">:</span><span class="w"> </span><span class="s2">&quot;some group&quot;</span><span class="w"> </span> <span class="w"> </span><span class="p">}</span><span class="w"> </span> <span class="w"> </span><span class="err">....</span> </code></pre></div></p> <p>The <code>pagination</code> field contains all the important information that you need.</p> <ol> <li>The field <code>limit</code> describes the number of groups contained in each page. By default it's <code>1000</code> but one can ask up to <code>5000</code> groups per page. If you want to set it to a different value you can define it in your initial request like this: <code>https://authorization-service-api.web.cern.ch/api/v1.0/Group?limit=500</code>.</li> <li>The field <code>total</code> describes the total amount of groups that are stored in the DB.</li> <li>The field <code>links</code> contains all the links to which the user should post another request to get the the next chunk of groups. In more detail:<ul> <li><code>next</code>: gives the user the next page of groups. If it's <code>null</code> it means there are no more pages to retrieve.</li> <li><code>previous</code>: gives the user the previous pages of groups.

Some of the fields have an actual null value (e.g. <code>blockingDeadline</code> or <code>expirationDeadline</code>), but others are fields that belong to other child objects, which are not computed by default to make the API more efficient. If you need any of these fields, you can specify them in the request using the <code>field</code> parameter.</p> <p>For example, for getting <code>primaryAccountEmail</code>:</p> <p><code>https://authorization-service-api.web.cern.ch/api/v1.0/Identity/aaguadoc?field=primaryAccountEmail&amp;field=upn</code></p> <div class="highlight"><pre><span></span><code>{ &quot;request_id&quot;: null, &quot;message&quot;: null, &quot;data&quot;: { &quot;primaryAccountEmail&quot;: &quot;asier.aguado@cern.ch&quot;, &quot;upn&quot;: &quot;aaguadoc&quot;, &quot;id&quot;: &quot;4499f2b8-2bcd-4d0a-bf81-73c119fb7bf9&quot; } } </code></pre></div> <p>As you can see in the example, when specifying fields in the request all the others are ignored in the response (even the default ones). If you also want to get them (e.g. <code>upn</code>) you can include them in your request as well.</p> </article> </div> </div> </main> <footer class="md-footer"> <nav class="md-footer__inner md-grid" aria-label="Footer" > <a href="../../services/instances/" class="md-footer__link md-footer__link--prev" aria-label="Previous: Links to instances" rel="prev"> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M20 11v2H8l5.5 5.5-1.42 1.42L4.16 12l7.92-7.92L13.5 5.5 8 11h12Z"/></svg> </div> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Previous </span> Links to instances </div> </div> </a> <a href="../managed-applications/" class="md-footer__link md-footer__link--next" aria-label="Next: Managing applications for other users" rel="next"> <div class="md-footer__title"> <div class="md-ellipsis"> <span class="md-footer__direction"> Next </span> Managing applications for other users </div> </div> <div class="md-footer__button md-icon"> <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M4 11v2h12l-5.5 5.5 1.42 1.42L19.84 12l-7.92-7.92L10.5 5.5 16 11H4Z"/></svg> </div> </a> </nav> <div class="md-footer-meta md-typeset"> <div class="md-footer-meta__inner md-grid"> <div class="md-copyright"> Made with <a href="https://squidfunk.github.io/mkdocs-material/" target="_blank" rel="noopener"> Material for MkDocs </a> </div> </div> </div> </footer> </div> <div class="md-dialog" data-md-component="dialog"> <div class="md-dialog__inner md-typeset"></div> </div> <script id="__config" type="application/json">{"base": "../..", "features": [], "search": "../../assets/javascripts/workers/search.5bf1dace.min.js", "translations": {"clipboard.copied": "Copied to clipboard", "clipboard.copy": "Copy to clipboard", "search.config.lang": "en", "search.config.pipeline": "trimmer, stopWordFilter", "search.config.separator": "[\\s\\-]+", "search.placeholder": "Search", "search.result.more.one": "1 more on this page", "search.result.more.other": "# more on this page", "search.result.none": "No matching documents", "search.result.one": "1 matching document", "search.result.other": "# matching documents", "search.result.placeholder": "Type to start searching", "search.result.term.missing": "Missing", "select.version.title": "Select version"}}</script> <script src="../../assets/javascripts/bundle.37e9125f.min.js"></script> </body> </html>
