What is Easypost, and how do I integrate it?

Easypost is a shipping API that allows 3rd party apps (like Rhythmic Equations) to programmatically view and select courier shipping options and print shipping labels. Payment information can be set up directly with Easypost by linking your Rhythmic Equations account to your Easypost shipping account. Once that's setup, shipping orders is seamless!

What if I need to return an order?

Refunds and returns can be handled directly from the platform the sale was made on, but you can also create a return shipment directly from Rhythmic Equations.

Will Rhythmic Equations always be free?

For now, Rhythmic Equations is completely free for use. However, in order to make the platform even better, we are going to start a subscription model where you will be charged a monthly fee. Our goal is to continue to help the record store community optimize their processes and reach new markets so that record stores don't have to close their doors. We are record storeowners too, after all.
