A maximum number of carrier accounts per Ship&co account now applies consistently, in the app and through the API:
FedEx, DHL, UPS: 5 accounts
Yamato, Sagawa, Seino custom carriers: 3 accounts
All other carriers: 1 account
If you already have more accounts than the limit for a carrier, you keep them all — you just can’t add a new one. On the Carriers page, a carrier at its limit appears greyed out with a message. Need more? Contact us to raise the limit for your account.
If you use the API with several accounts of the same carrier, remember that setup.carrier_id is required to choose which one to charge.
