Question 2

Why is BitPayPostage cheaper than USPS retail?

Accepted Answer

We use commercial rates plus a small service fee. For most flat-rate packages you'll pay close to USPS retail. Heavier packages and Priority Express are usually cheaper than the post office.

Question 3

How do refunds work for unused shipping labels?

Accepted Answer

Unused labels can be voided within the carrier's window — typically 14-28 days. Voided labels are refunded as account credit (not cash). Non-refundable if the label has been scanned by the carrier.

Question 4

Do you offer a shipping API?

Accepted Answer

Yes. Public REST API at /api/v1 with x-api-key authentication. Endpoints for rates, label creation, tracking, and address validation. Used by third-party shopping carts and crypto checkouts.

Question 5

What carriers are supported?

Accepted Answer

USPS, UPS, FedEx, DHL Express, Canada Post, Royal Mail, Australia Post, Deutsche Post, Japan Post, and 50+ international postal services through ShipEngine.

Question 6

Can I print labels at different sizes?

Accepted Answer

Yes. Choose 4×6 thermal (Rollo, Dymo, Zebra), 8.5×11 letter for desktop printers, 2-per-page for Avery sticker sheets, or A6 for international thermal.
