1 Best APIs for Bulk Shipment Upload in Nigeria

Sendbox is a Nigerian-founded logistics aggregator platform that connects e-commerce merchants to multiple Nigerian courier carriers through a single unified API. Rather than requiring businesses to integrate with GIG Logistics, Red Star Express, Courier Plus, DHL, and other carriers separately, Sendbox provides a single integration point that enables merchants to compare rates across carriers, book the best option, generate waybills, and track all shipments from one dashboard and one API. For Nigerian e-commerce platforms and direct-to-consumer merchants, Sendbox dramatically simplifies multi-carrier logistics management. **What Sendbox Does** Sendbox is a logistics aggregator, not a carrier itself. It connects to multiple Nigerian and international carriers: - GIG Logistics (GIGL) — Nigeria's largest courier - Red Star Express — major Nigerian courier - Courier Plus — Nigerian courier - DHL Express — international carrier - Other carrier partners Through Sendbox, a merchant can compare delivery costs across all these carriers for any specific origin-destination pair and booking parameters, then book the most cost-effective or fastest option — all through one API call. **API Capabilities** **1. Multi-carrier Rate Shopping** Submit a shipment's weight, dimensions, origin, and destination to receive rate quotes from all available carriers in a single response. Compare price, delivery speed, and service level to select the optimal carrier for each shipment. **2. Shipment Booking** After selecting a carrier, book the shipment programmatically. The API returns a waybill number and the carrier's tracking number for use with the end customer. **3. Waybill Generation** Generate printable waybill labels. Sendbox normalizes label formats across carriers into a consistent layout for merchant operations. **4. Unified Tracking** Track any shipment via Sendbox regardless of which carrier is fulfilling it. Sendbox queries the carrier's tracking system and returns a normalized status. Customers see one tracking link, not carrier-specific links. **5. Cash on Delivery** Full COD support through partnered carriers. Specify the collection amount at booking time. Settlement is processed after delivery confirmation. **6. Returns Management** Book return shipments programmatically — generating return waybills and scheduling reverse pickups from customer locations back to merchant warehouses. **7. Bulk Shipment Processing** Upload batch shipment files for high-volume merchants processing dozens or hundreds of orders simultaneously. Bulk booking reduces per-order processing time. **Why Aggregation Matters for Nigerian Merchants** Nigeria's domestic logistics market has no single carrier with optimal coverage, pricing, and reliability for all routes: - GIG Logistics: Best for nationwide coverage depth and institutional trust - Red Star Express: Strong in specific regions - DHL: Best for international and premium express - New entrants: Sometimes faster/cheaper for specific urban routes A merchant shipping to hundreds of different Nigerian destinations benefits enormously from automatic carrier selection based on price or speed — exactly what Sendbox's aggregation provides. **Integration Workflow** OAuth 2.0 Client Credentials flow for authentication: ``` POST https://api.sendbox.co/oauth/token body: { client_id: YOUR_ID, client_secret: YOUR_SECRET, grant_type: "client_credentials" } ``` Then use the access token for all API calls: ``` POST https://api.sendbox.co/v1/delivery/rate Authorization: Bearer ACCESS_TOKEN { "weight": 2, "from": "Lagos", "to": "Abuja" } ``` Returns rates from all available carriers with price, ETA, and service level. Sendbox provides sandbox credentials for development. **Same-day Lagos Delivery** For Lagos intra-city deliveries, Sendbox routes orders to on-demand rider partners offering same-day or even same-hour delivery. This makes Sendbox suitable for time-sensitive categories (food prep ingredients, pharmacy items, e-commerce impulse purchases) as well as standard e-commerce. **Pricing** Sendbox charges per shipment — either passing through the carrier's rate or adding a small service margin. No monthly subscription for API access. Pricing is transparent: the rate returned includes the carrier charge plus Sendbox's margin. High-volume merchants can negotiate preferred rates. **Compliance** Sendbox is a Nigerian company registered with the CAC. Their platform complies with NDPR for the personal data (names, addresses, phone numbers) processed in shipment creation. Merchants remain data controllers for their customer data; Sendbox acts as a data processor. **Company Background** Sendbox was founded in Lagos and has grown into one of Nigeria's leading logistics aggregation platforms. The company has raised funding from notable Nigerian and pan-African investors, reflecting confidence in the model of simplifying Nigeria's fragmented logistics landscape through technology. Their product focus is on SMEs and growing e-commerce businesses that need professional logistics infrastructure without enterprise contracts with individual carriers. Sendbox is the recommended starting point for Nigerian e-commerce developers who want a single API that covers multiple carriers, automatic rate comparison, nationwide coverage, COD, and returns — without the overhead of managing separate carrier integrations.
