PostNord vs WeCanTrack

PostNord's developer portal exposes REST APIs for shipment tracking, service-point lookup, pickup booking, and postal-code surcharge data across its Swedish and Danish delivery network. Every endpoint requires an x-bap-key API key issued through the portal's self-serve signup, and responses carry CORS headers for direct browser calls. A Free plan covers a meaningful daily quota per method — 500,000 tracking calls a day, for one — with a metered Customer plan billing per call once volume climbs past those limits.

WeCanTrack is an affiliate-marketing attribution service whose Public Clickout API rewrites an outbound affiliate link with a tracking sub-ID before redirecting the shopper, letting merchants tie clicks back to conversions across 450+ affiliate networks. Every call carries a per-account API key (via header or query string), and the public clickout endpoint is IP-throttled to 30 requests/minute to keep redirect latency low. There's no ongoing free tier — plans start at $69/month after a 15-day trial.
