These rate limits are already in effect for accounts created after July 2019.</p><h2 id="h_01K3A7DY1MGYWC5Z9FE5WEZMD9">Why is Zendesk making this change?</h2><p>We are making this change to provide greater stability and robustness within each of our data centers and ensure that the rate at which update requests are being made provides consistent performance from account to account.</p><h2 id="h_01K3A7FEPQBH8P3JPGKNBZRT8C">What do I need to do?</h2><p>If your account was created after July 2019, you’re already subject to these rate limits. </p><p>If your account was created before July 2019 you may need to monitor your integrations to ensure that you’re making calls that fall below the new rate limits, or that you have implemented an adequate fallback mechanism into your API calls. You also might want to consider migrating your API calls to the update_many endpoint (<a href="https://developer.zendesk.com/api-reference/ticketing/tickets/tickets/#update-many-tickets"><span class="wysiwyg-underline">API documentation</span></a>), where instead of synchronous calls being used a bulk job is created to manage the updates more efficiently asynchronously, where a job status is returned in the call.  </p><ul>
