Using the Custom Shipping Rate Service

The Custom Shipping Rate Service enables you to provide shipping rates to Recharge during checkout and recurring orders. You can dynamically calculate rates directly from your shipping providers or from your own custom set-up by providing a custom callback URL that Recharge will call to get rates.

This guide provides the steps to implement the Custom Shipping Rate Service app on your Recharge store.

Before you start

• This feature is available for merchants using the Recharge Checkout on Shopify or BigCommerce, or the Recharge API.
• You must be using the advanced shipping rates (Recharge zones, rates, and integrations) in your Shipping settings in Recharge.
• This feature requires the use of API and custom code. Implementation cannot be performed or supported by Recharge as per the design and integration policy. If you require assistance from a developer, please visit the Recharge Partner Directory.
