Troubleshooting

If requests fail, run zero doctor check-connector --env-name DUFFEL_TOKEN or zero doctor check-connector --url https://api.duffel.com/air/airlines --method GET

Authentication

All requests require an access token passed in the Authorization header using the Bearer scheme, plus a Duffel-Version header to pin the API version.

Authorization: Bearer $DUFFEL_TOKEN
Duffel-Version: v2

Tokens starting with duffel_test_ access test mode (sandbox airlines, fake cards); tokens starting with duffel_live_ access live mode. Test mode cannot be used with live tokens, and vice versa.
