      <p>
        These are the checks performed by Shlink in order to determine if an existing short URL should be returned:
      </p>
      <ul>
        <li>
          When only the long URL is provided: The most recent match will be returned, or a new short URL will be created
          if none is found
        </li>
        <li>
          When long URL and custom slug are provided: Same as in previous case, but it will try to match the short URL
          using both the long URL and the slug.
          <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
        </li>
      </ul>
