2 Best APIs for Generation in Nigeria

The goqr.me QR Code Generator API is one of the simplest and most accessible QR code generation services available, providing an HTTP-based API that generates QR code images for any URL, text, or structured data by passing parameters directly in a GET request URL. No API key, no account registration, no SDK installation, and no complex setup — a Nigerian developer can generate a QR code in their application within minutes of discovering the service. The simplicity of the approach makes it an excellent choice for Nigerian applications that need QR code generation without the overhead of a feature-heavy paid service. QR codes are ubiquitous in the Nigerian digital economy. Nigerian banks, fintech apps, restaurants, event organizers, retailers, and government agencies all use QR codes to link physical world interactions to digital experiences. Payment QR codes enable merchants to accept transfers by displaying a scannable code. Menu QR codes replaced physical menus in many Nigerian restaurants post-COVID. Event tickets use QR codes for entry verification. Product labels link to warranty registration and support pages. For Nigerian developers building any of these use cases, programmatic QR code generation is a frequent requirement. The API works by calling a URL endpoint with the data to encode. The most basic usage appends the data as a chl (content) parameter and the API returns a QR code image directly. The size of the generated image is controlled by the size parameter (width and height in pixels, from 10 to 1000). Output format can be PNG (default), SVG, or EPS, depending on the downstream use case — PNG for web display, SVG for print and scalable applications, EPS for professional design workflows. Error correction level is an important QR code parameter — higher error correction (levels L, M, Q, H) makes QR codes readable even when partially obscured or damaged, at the cost of larger and denser codes. For Nigerian product labels that may get scratched or dirty in retail environments, a higher error correction level (Q or H) is recommended. The API accepts this as the ecc parameter. Color customization allows Nigerian developers to match QR codes to brand guidelines. The bgcolor and color parameters specify background and foreground colors in hexadecimal format, enabling generation of QR codes in brand colors rather than the default black-and-white. This is useful for Nigerian marketing materials where QR codes are part of branded designs. Margin control via the margin parameter sets the quiet zone (white space) around the QR code in pixels. This ensures QR codes are scannable when embedded in busy designs where surrounding content might otherwise interfere with scanning. A margin of at least 4 modules (typically 16-20 pixels at standard sizes) is recommended for reliable scanning. For Nigerian developers who need more features — dynamic QR codes (changing destination without reprinting), scan analytics, or password-protected QR codes — dedicated QR code platforms like QRCode Monkey (also listed in this directory) provide these capabilities at affordable pricing. The goqr.me QR code API supports Wi-Fi network QR codes — encoding SSID, password, and security type so mobile devices can join a Wi-Fi network by scanning a QR code. Nigerian businesses like cafes, hotels, and co-working spaces can generate Wi-Fi QR codes programmatically for display at their venues, eliminating the need for staff to verbally share Wi-Fi passwords with customers. vCard QR codes encoding contact information (name, phone, email, address, website) can be generated through the API for use on business cards and marketing materials. Nigerian professionals and businesses can use QR business cards that allow smartphone contacts to be added by scanning rather than manual entry — improving networking efficiency at Nigerian business events and conferences.

Duply.co is a visual content automation platform that provides a template-based image and PDF generation API for developers and marketers who need to produce personalized, branded visual content at scale. Nigerian businesses generating consistent visual output — promotional graphics, social media posts, personalized greetings, property listings, and certificates — can use Duply to design their visual templates once and then generate unlimited personalized variations through API calls, eliminating repetitive manual design work. Nigeria's digital marketing and content creation ecosystem has grown substantially, with Nigerian businesses across industries investing in social media presence, digital advertising, and branded visual communication. The challenge is producing high volumes of consistent, on-brand visual content efficiently. Duply addresses this by providing a drag-and-drop template editor where Nigerian designers build the visual foundation — brand colors, typography, logo, layout structure — and then engineers connect the template to live data through the API to generate personalized versions. The Duply template editor is browser-based and requires no design software installation. The canvas interface supports multiple layer types: text layers (for dynamic names, prices, dates, headlines), image layers (for product photos, user avatars, dynamic visuals), and shape layers (for backgrounds, dividers, and decorative elements). Each layer can be set as static (same in every generation) or dynamic (populated from API variables). Nigerian designers comfortable with Canva or PowerPoint can build effective Duply templates without advanced design training. The generation API accepts a template ID and a JSON payload of variable values, returning either a synchronous response with the generated image URL (for fast templates) or an asynchronous job ID that completes via webhook notification (for complex templates). The API supports PNG, JPEG, and PDF output formats. For Nigerian platforms generating high volumes — e.g., a Nigerian food delivery app creating a unique promotional banner for each of 50,000 registered restaurants — batch generation endpoints process multiple variations in a single request. WhatsApp marketing is a major use case for Nigerian businesses. Nigerian companies running WhatsApp campaigns can use Duply to generate personalized promotional images for each customer — inserting the customer's first name, a personalized discount code, or a product recommendation into a branded template. This level of personalization is proven to increase engagement compared to generic images, and Duply automates the production that would otherwise require a designer to manually create each variation. The free tier provides 50 images per month — sufficient for experimentation and low-volume production. Starter ($19/month) provides 1,000 images suitable for small Nigerian businesses. The Pro tier ($49/month, 5,000 images) and Business tier ($99/month, unlimited) serve growing Nigerian platforms with higher volume needs. Duply also provides a REST API for batch template rendering — submitting multiple rendering jobs simultaneously rather than sequential individual requests, which is more efficient for high-volume document generation workflows. Nigerian HR platforms generating monthly pay slips for hundreds of employees, or e-commerce platforms generating invoices for large order batches, can use batch rendering to complete the entire generation job in much less time. The variable substitution system supports conditional blocks within templates — content that appears only when specific variables are set or meet specific conditions. Nigerian developers can build templates that adapt their content based on the data provided: showing different sections for different document types, hiding optional sections when data is absent, or displaying different formatting for different customer tiers.
