Steps
Obtain a valid FedEx OAuth 2.0 Bearer token (see token endpoint above) and have your FedEx account number ready.
POST /rate/v1/rates/quotes with a JSON body containing 'accountNumber' (object with 'value'), 'requestedShipment' including 'shipper' and 'recipient' addresses (each with 'address' sub-object), 'pickupType', 'serviceType' (omit to get all services), 'rateRequestType' (e.g., ['ACCOUNT', 'LIST']), and 'requestedPackageLineItems' array with weight and dimensions.
The response 'output.rateReplyDetails' is an array; each entry has 'serviceType', 'ratedShipmentDetails' array where each element has 'totalNetCharge', 'totalBaseCharge', and 'shipmentRateDetail.rateZone'.
To get all available service rates in one call, omit 'serviceType' from the request — FedEx returns rates for every eligible service.
Parse and sort the 'totalNetCharge' values across service types to find the lowest-cost option meeting your delivery requirements.
Known gotchas
Account rates ('ACCOUNT') require a valid FedEx account number with negotiated rates; LIST rates are publicly available but higher. Always request both to see your actual pricing.
Dimensional weight is calculated automatically by FedEx if dimensions are provided; omitting dimensions returns a rate based on actual weight only, which may not reflect what you'll be billed.
The sandbox environment returns plausible but not production-accurate rate figures; always validate rates in production before relying on them for cost calculation.
