Bring your own EasyPost account

1. Open Settings → Shipping and select Enable shipping labels.
2. Under Use Your Own EasyPost Account, enter your EasyPost API key. A production key starts with EZAK and a test key with EZTK.
3. Select Save settings.

ZenReturn then buys every label with your key. EasyPost bills you for these labels, and ZenReturn adds no label charge to your Shopify bill. Your Carrier preference applies to the rates your account returns. As with ZenReturn labels, ZenReturn uses only rates in US dollars.

ZenReturn stores the key encrypted and shows only its first characters. When you save a key, ZenReturn sets up tracking updates on your EasyPost account. If the page says that tracking updates are not connected, save the settings again, and re-enter the key if the notice stays.

Stop using your account

Clear the API key field and select Save settings. ZenReturn then buys labels through its own account, billed as usage on your Shopify bill.

To void a label that you bought with your key, the key must still be saved. If you removed it, add it again in Settings → Shipping.

If your store moves to a plan without this feature, ZenReturn keeps the key but does not use it. Labels are then bought through ZenReturn and billed to your Shopify bill. The feature needs the Standard plan or higher.
