Each carrier requires a set of credentials that ShipCelero uses to communicate with the carrier's API on your behalf. These credentials come from your existing carrier agreement — you cannot use ShipCelero's rates.
Where to add credentials
Go to Settings → Integrations. Each carrier appears as a card. Click Connect (or Edit for an existing connection) to open the carrier's configuration page.
PostNord credentials
- Country — the PostNord company your agreement is with: PostNord Denmark (Z11), Sweden (Z12), Norway (Z13), or Finland (Z14)
- Customer ID — your PostNord customer number, found in your PostNord business agreement or customer portal
Bring credentials
- Mybring Email (API UID) — the email you log in to mybring.com with
- API Key — from your Mybring profile
- Customer Number — your Bring customer number
DAO credentials
- Customer ID (kundeid) — from your DAO agreement or the dao.as portal
- API Password (kode) — found under API access in the dao.as portal; contact DAO support if you do not have API access yet
Etsy
Etsy is connected with an authorisation flow instead of credentials — see Connecting your Etsy shop.
Preferences and test mode
Each carrier page also has label preferences, such as a default service. New connections start with Test mode enabled so you can try the flow without booking real labels — remember to switch it off before shipping for real.
Testing your connection
Use the Test connection button on the carrier page to verify your credentials immediately. If the test fails, double-check every field against your carrier portal. After a successful test, create a shipment to confirm services load for your destinations.
