title: Bigcommerce API sending no response sometimes intermittently
body: <p>I have Bigcommerce store and I have permission to access 60,000 API calls per hour as per Bigcommerce supporter. I have used Bigocommerce Api to fetch the all the products (50,000) from my store using one function. That function working fine for me but whenever I am trying to fetch all the products custom field name &amp; value using below function on that time sometimes Bigcommerce API sending no response intermittently.</p>
  
  <pre><code>$data = Bigcommerce_Api::getProductCustomFields('Product ID');
  </code></pre>
  
  <p>First I have fetched the all the products from my store and saved it on my temporary table. After-that using php/mysql loop I have fetched all the products one by one from my table and passed the Product Id to the above Api function to fetch the product custom field name &amp; value. But I have seen that after successfully fetching approx 30k products custom field,  for some time Bigcommerce API sending no response intermittently. I have discussed with Big-commerce supporters as well and they told me that there was no issue from their end &amp; it was set up correctly. </p>
  
  <p>Please suggest me how can I resolve that issue.</p>
  
  <p>thanks in advance</p>
