2 Best APIs for Label generation in Nigeria

ShipEngine is a multi-carrier shipping API aggregating 50+ carriers globally (USPS, UPS, FedEx, DHL, and various regional/local carriers) under a single integration, primarily built for US and international e-commerce but with carrier coverage that extends into African and Nigerian logistics partners as part of its broader carrier network. A single API call returns comparable rate quotes across all connected carriers for a given shipment, and label generation/booking follows the same unified request format regardless of which carrier is ultimately selected. Beyond rate shopping and label printing, ShipEngine provides address validation (catching malformed addresses before a shipment is booked, reducing failed-delivery costs), tracking updates aggregated into one webhook format regardless of carrier, and batch operations for processing large volumes of orders at once — relevant for a marketplace or high-volume e-commerce platform processing hundreds of daily shipments. For Nigerian businesses that ship internationally (exporting products, or a marketplace with both local and cross-border sellers), ShipEngine's primary strength is depth of *international* carrier coverage and address validation for non-Nigerian destinations — for purely domestic Nigerian shipping, a Nigeria-focused aggregator like Shipbubble typically has stronger local carrier relationships and pricing. ShipEngine bills on a per-shipment/API-call basis with a free sandbox for development.

Easyship is a global multi-carrier shipping platform and API aimed at cross-border e-commerce, aggregating rates across dozens of international couriers and postal services to help merchants find the cheapest or fastest option for shipping a given package to a given country, including automatic duty and tax calculation shown to the buyer at checkout (avoiding the surprise import-fee-at-the-door problem that causes abandoned cross-border deliveries). The API covers rate shopping across connected carriers, label generation, automated customs documentation for international shipments, and a "landed cost" calculator that estimates total cost (shipping + duties + taxes) for a buyer in a specific destination country before they complete checkout — a feature specifically aimed at reducing cart abandonment on international orders. Tracking updates are aggregated into a single format across all supported carriers. For Nigerian e-commerce merchants selling internationally — exporting Nigerian-made goods, fashion, or crafts to diaspora customers or international buyers — Easyship's landed-cost-at-checkout and customs automation address two of the biggest friction points in cross-border e-commerce from Nigeria: unpredictable delivery costs for the buyer and manual customs paperwork for the seller. For purely domestic Nigerian delivery, Easyship is not the right tool; it's specifically oriented toward international shipment flows.
