Question 1

What does Duply Image Generation API do?

Accepted Answer

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.
