+        <li>
+          When long URL and custom slug and/or domain are provided: Same as in previous case, but it will try to match
+          the short URL using both the long URL and the slug, the long URL and the domain, or the three of them.
+          <br />
+          If the slug is being used by another long URL, an error will be returned.
+        </li>
+        <li>
+          When other params are provided: Same as in previous cases, but it will try to match existing short URLs with
+          all provided data. If any of them does not match, a new short URL will be created
