Looking for a PHP script to send orders to our supplier and get the order status back from the supplier via API

1. Before import the order to our supplier website via API, we need to get the order status, etc. from our supplier, details see Notes (in the column T) of the file “[login to view URL]” 2. If one order has more than one product, all the products should be imported one time. 3. IF the order importing failed, add the failed time and the failure info to the csv file "[login to view URL]" 4. We can use an URL to start the PHP script manually, and we can also set a cronjob using this URL, so that we can set an automatic task for this script. We can set IP whitelist for this URL (add IP address to the PHP code or another method), the URL will be invalid for the IPs if the IPs are not in the whitelist. 5. Our supplier has written sample codes (file: “Code [login to view URL]”) for all the APIs, you can copy all the codes for this project, so you just need to write a little code for this project. 6. please write comments for each line 7. we need the source code 8. More details see the attachments. Attachments: [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] Code [login to view URL] Besides the file “Code [login to view URL]”, all the other files will be stored on our server, the script will also run on the same server.
