title: BigCommerce API issue with page limit
body: <p>I am working on a task in which i need to fetch bigcommerce products check for product url's to generate sitemap.xml file</p>
  
  <p>Actually there are 180000 products on site so i will need to create multiple sitemap xml files and a single index (sitemap.xml) file.</p>
  
  <p>I completed all script to do that, i am grouping 50000 url's in every sitemap xml files created.</p>
  
  <p>When i run it, once it was executed correctly and created 4 sitemap files.
  all was worked fine.</p>
  
  <p>But now i am unable to execute it coz after running for sometime it gives me network error (Something like bigcommerce connection lost)</p>
  
  <p>The issue is that there is a limit while calling bigcommerce api, coz we need to send it a page no and at a time only 250 products are fetched.</p>
  
  <p>so i asked to bigcommerce support person for extending limit for fetching products in a single api call. he suggested me to use loop and informed me that there is no any solution for it, we can fetch only 250 products at a time.</p>
  
  <p>its difficult to fetch 180000 products in single script calling api in loop.
  but in my case its compulsory for me to do that in a sigle script (i need to set that script as a cron job).</p>
  
  <p>Is there any solution do accomplish this task without any network error.
  Any bigcommerce expert here?</p>
  
  <p>Any help would be greatly appreciated!! </p>
