I need to develop an app to retrieve a sales report from shopify or magento accounts. Please read attached PDF and ask question.
1. There will be a PHP app on my server to retrieve the reports.
2. There will be a shopify and magento app to appear in shopify or magento store.
Developers with Apps already listed in Shopify or Magento app store or marketplace are preferred. Please give me links to your apps approved and listed in their store.
