how could I find the application/plug-in which send order information to a website called easypost.com

I have an internal website written in php and java. its main function is collecting order information from online stores on ebay and Amazon. After it collect orders, it will send the order information to a third party website called www.easypost.com to print shipping labels.

since the company changed their office recently, they have to update the ship from address printed in the label. I have contacted the technical support in easypost.com and their tech said the "ship from " addres is in my website or in my plugin.

here is his reply:"Hi Jason,

You change this in the from_address you're sending us OR in your plugin.

Best,"

Dear support:

I have a label created from your website. We moved our office recently and want to change the "ship from" address which is "AA ECD…." On the label. Could you please advise where I can change it.

Thanks.
