title: How to configure GCP Cloud Tasks Queue for very slow dispatch due to 3rd party SLA downstream?
body: <p>I need to set up a Cloud Tasks queue that sends HTTP requests to a 3rd party API. The external API can only accept a few requests per minute and I would like to set up rate limiting on the Cloud Tasks so that tasks flow at a very slow pace: no more than 1 request every 15 seconds.</p>
  <p>From the docs, I can see that:</p>
  <p>When you use any Cloud Tasks API method, you have two fields to define the queue dispatch rate:</p>
  <p>max_dispatches_per_second
  max_concurrent_dispatches</p>
  <p>I have set both of those parameters to 1. My questions are:</p>
  <p>How can I achieve my goal of 1 request per 15 seconds using these parameters?
  Can I set max_dispatches_per_second to something like 0.10?</p>
  <p>Thanks for any insight!</p>
