5 Best APIs for Backend in Nigeria

ExtendsClass JSON Storage is a free, zero-setup online JSON data bin service that allows developers to store, retrieve, update, and delete JSON objects via a simple REST API — without needing to create a database, configure a backend server, or even register for an account. A developer can POST any JSON data to the service and receive back a unique URL that retrieves that stored JSON, making it immediately useful for rapid prototyping and data sharing scenarios. The service provides standard CRUD operations on stored JSON objects: POST to create a new storage bin and receive an ID, GET to retrieve stored JSON by ID, PUT to replace the stored JSON entirely, PATCH to partially update fields, and DELETE to remove a bin. This familiar REST interface means any developer comfortable with standard HTTP operations can use it immediately without learning a new API paradigm. For prototyping purposes, the most common use case is giving a static frontend application a place to persist data without building a backend. A Nigerian developer building a demo or proof-of-concept can store form submissions, user-created content, or application state in ExtendsClass JSON Storage bins and retrieve them on page load — simulating persistence without any server-side code. This dramatically accelerates the time to a working demo, which is valuable for pitching ideas, client presentations, and hackathon projects. The service is also excellent for sharing structured JSON data between developers. Rather than attaching JSON files to messages or pasting large JSON blobs in chat threads, a developer can store the JSON in ExtendsClass, share the URL, and teammates can inspect or copy the data by visiting that URL. This works for sharing API request/response examples, test data structures, and configuration samples. ExtendsClass offers many other developer tools on its platform beyond JSON Storage — regular expression tester, cURL builder, JSON formatter and validator, XML formatter, and more — making it a useful bookmarked resource for Nigerian developers who frequently need quick developer utilities. No registration is required for basic usage, and the service is free. The simple REST interface works with any HTTP client — curl, Fetch API, Axios, Python requests, or any language's HTTP library. Response times are fast enough for integration testing and prototyping workflows. For Nigerian developers in environments where setting up a database for a small project is impractical — limited time, no DevOps resources, or a restricted server environment — ExtendsClass JSON Storage provides a pragmatic solution that unblocks development without infrastructure overhead. Beyond basic JSON bin functionality, ExtendsClass JSON Storage supports setting a time-to-live (TTL) on stored bins, automatically deleting them after a configured duration. This ephemeral storage mode is ideal for short-lived test data, temporary configuration sharing, and time-bounded demo scenarios where the data should not persist indefinitely. The service also provides a web interface for creating and inspecting JSON bins without API calls, which is useful for non-technical team members who need to view or update shared data without writing code. This dual access mode (API and web UI) makes it useful for cross-functional Nigerian teams where developers and non-developers need to share structured data. Nigerian developers using ExtendsClass JSON Storage for form data persistence in no-backend prototypes should note the public nature of basic bins — stored data is accessible to anyone with the bin ID. For sensitive data, private bins with API key protection are available on the service. The broader ExtendsClass developer tools platform offers companion utilities including a REST API client tester, JSON validator and formatter, XML formatter, and regular expression tester — making it a useful bookmark for Nigerian developers who frequently work with structured data formats.

JSONbin.io is a cloud-based JSON storage API that provides a free, simple REST endpoint for storing, retrieving, updating, and organizing JSON documents. It operates on the concept of "bins" — individual JSON storage containers that can be created, read, updated, and deleted via standard HTTP verbs. JSONbin is designed for developers who need fast, zero-setup JSON persistence without deploying any backend infrastructure or database system. The central workflow of JSONbin is simple: POST a JSON document to the API and receive a bin ID in response. That bin ID then serves as the address for subsequent GET requests to retrieve the stored JSON, PUT requests to overwrite it, and DELETE requests to remove it. Each bin can hold any valid JSON structure — flat key-value pairs, nested objects, arrays of objects, or mixed structures — with no schema enforcement or data type restrictions beyond what JSON itself defines. JSONbin.io offers both public and private bins. Public bins are readable by anyone with the bin ID, making them suitable for shared configuration data, publicly accessible API mock responses, or shared application state in collaborative settings. Private bins require an API key for access, making them appropriate for storing application-specific data, user settings, or data that should not be publicly discoverable. The privacy setting can be toggled per bin based on the sensitivity of the stored data. Collections in JSONbin allow bins to be organized into named groups. For developers managing multiple bins across different projects, features, or environments, collections provide a way to keep bins organized and queryable as a group. The API supports listing all bins within a collection, enabling applications to dynamically discover and iterate over stored bins without maintaining a separate index of bin IDs. Version history is an important JSONbin feature for data that changes over time. Each time a bin is updated, JSONbin preserves the previous version, allowing applications to retrieve the content of a bin as it was at any prior version. This versioning capability turns JSONbin into a lightweight audit trail for data changes, useful for tracking configuration changes, form submission histories, or evolving datasets in prototype applications where a full versioned database is not warranted. For Nigerian developers, JSONbin.io fills a practical gap in the prototyping and learning toolkit. When building a proof-of-concept application, learning to work with REST APIs, or developing a demo for a hackathon presentation, the overhead of provisioning a database, setting up authentication, and writing CRUD endpoint handlers is disproportionate to the actual need. JSONbin eliminates this overhead entirely — any valid JSON can be stored and retrieved in seconds through the API. Mobile app developers in Nigeria building cross-platform applications that need a simple cloud sync mechanism for small amounts of user data — preferences, game scores, reading progress, bookmarks — can use JSONbin as a lightweight backend without provisioning a full backend service. The app reads its stored JSON from a private bin on startup, modifies it locally based on user actions, and writes the updated JSON back to the same bin when appropriate. This pattern supports basic cloud persistence for simple use cases without a dedicated server. JSONbin is also commonly used for storing mock API response data during frontend development. A Nigerian frontend developer building a dashboard that will eventually consume a production API can use JSONbin to store sample response data that the frontend can fetch from during development, allowing the frontend to be built and tested independently of backend API availability. The API is accessible from any HTTP client and is supported by CORS headers, allowing direct browser-side requests from JavaScript web applications. No server-side proxy is required for browser applications to read from and write to JSONbin bins. SDKs and wrapper libraries exist in the community, though the API is simple enough that most developers use it directly with the fetch API or axios without needing an additional library layer.

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside a web browser. Built on Google Chrome's V8 JavaScript engine, Node.js enables developers to use JavaScript for server-side programming, building everything from REST APIs and real-time applications to command-line tools and microservices. Since its release in 2009, Node.js has become one of the most widely used backend technologies globally, and it is arguably the most popular choice among Nigerian developers for building backend APIs and server-side applications. Nigeria's developer community has strongly embraced Node.js, driven by the fact that most Nigerian developers learn JavaScript first (for web frontend development) and can seamlessly transition to backend development using the same language. The Nigerian startup ecosystem is dominated by fintech, e-commerce, and service platforms, all of which benefit from Node.js's strengths: fast execution for I/O-heavy workloads, a massive npm ecosystem of ready-made packages, and a large community of Nigerian developers who can contribute to and maintain Node.js codebases. Node.js uses an event-driven, non-blocking I/O model that makes it highly efficient for applications that handle many concurrent connections — exactly the pattern required by payment APIs, notification services, and real-time dashboards that Nigerian fintech and tech startups build. When a Nigerian payment gateway receives thousands of simultaneous payment requests, Node.js handles each request asynchronously without blocking other requests while waiting for database queries or external API responses. The npm (Node Package Manager) ecosystem with over 2 million packages is one of Node.js's biggest advantages. Nigerian developers can add authentication (Passport.js, jsonwebtoken), database connectivity (Mongoose for MongoDB, Prisma for PostgreSQL), API frameworks (Express.js, Fastify, Hapi), payment SDK integrations (Paystack, Flutterwave official Node.js SDKs), and hundreds of other capabilities by simply adding npm dependencies. This package richness dramatically accelerates development compared to building from scratch. Popular Nigerian fintech companies, e-commerce platforms, and tech startups — including those providing payment processing, logistics tracking, and digital banking services — use Node.js for their backend APIs. The combination of performance, developer familiarity, ecosystem richness, and deployment flexibility (Node.js runs on all major cloud platforms including AWS, GCP, Azure, and Nigerian-hosted servers) makes it the default backend choice for a large share of the Nigerian tech industry. Node.js is maintained by the OpenJS Foundation and follows a predictable Long Term Support (LTS) release cycle, making it suitable for production applications. Even-numbered major versions (v18, v20, v22) receive LTS status and are recommended for production Nigerian deployments requiring long-term stability and security patches. Node.js's event-driven, non-blocking I/O architecture makes it particularly well-suited for Nigerian applications that need to handle many simultaneous connections efficiently — real-time chat applications, live notification systems, API gateways, and data streaming services all benefit from Node.js's ability to handle thousands of concurrent connections without the thread-per-connection overhead of traditional server architectures. The npm ecosystem — with over 2 million packages — provides ready-made solutions for nearly every common development task. Nigerian developers can find packages for Nigerian payment gateway integrations (Paystack, Flutterwave SDKs), authentication, database connections, cloud service integrations, and domain-specific utilities without building from scratch. Node.js's dominance in the JavaScript ecosystem means that Nigerian developers who write frontend JavaScript can apply the same language skills to backend development — reducing the cognitive overhead of context-switching between languages and enabling full-stack development with a single programming language.

The Heroku Platform API provides complete programmatic access to the Heroku cloud application platform, enabling developers to automate all aspects of application deployment, management, and scaling that are otherwise performed through the Heroku Dashboard or CLI. Through the API, external systems, CI/CD pipelines, and custom tools can manage Heroku applications as part of automated workflows. Application management through the API covers creating new applications, reading application metadata, updating configuration, managing collaborators, and deleting applications. This enables automated application provisioning — for example, creating a new staging environment for each feature branch, complete with its own Heroku app, database add-on, and environment variables. Dyno management is one of the most operationally important capabilities. The API allows scaling dynos up and down, restarting dyno processes, listing running dynos, and managing formation (the set of process types and quantities for an application). Nigerian applications with predictable traffic patterns — end-of-month billing spikes for fintech apps, daytime peaks for business services — can use the API to automatically scale dynos according to traffic schedules, reducing costs during low-traffic periods. Release management provides access to the full deployment history: listing all releases with their timestamps, the slug deployed, and the user who triggered the release. Rollback operations (restoring a previous release) can be performed via API — enabling automated rollback triggered by health check failures or deployment monitoring systems detecting issues. Add-on management allows attaching, detaching, and configuring Heroku add-ons (databases, caches, email services, monitoring tools) programmatically. Automated environment provisioning can include setting up the full add-on stack alongside the application code deployment. Config vars (environment variables) can be set, updated, and retrieved via API. Automated deployment pipelines can update API keys, database connection strings, and feature flags as part of deployment workflows without manual configuration updates. Pipeline management supports the Heroku Pipelines feature — promoting application slugs from one stage (staging) to another (production) without re-building. The API enables automated promotion workflows where a successful staging deployment automatically triggers a production promotion after passing tests. For Nigerian startups and development agencies using Heroku for hosting, the Platform API transforms manual deployment workflows into automated, reliable processes integrated with their broader development toolchain. Heroku's review app feature can be automated via the Platform API — automatically creating and destroying preview environments for each pull request in the development workflow. Nigerian development teams practicing pull request-based development can automate the creation of isolated preview environments for each code review, giving reviewers a live environment to test changes before merging. The SSL certificate management API handles HTTPS certificate provisioning and renewal for custom domains. Nigerian applications using custom .ng domains on Heroku can automate SSL certificate management, ensuring HTTPS is always active without manual renewal processes. Heroku's data services API covers PostgreSQL, Redis, and other managed data add-ons. Programmatic access to database credentials, connection strings, and maintenance scheduling enables Nigerian development teams to automate database provisioning as part of environment creation workflows — creating fully configured staging environments including databases with a single automation script.

Hasura is an open-source GraphQL and REST API engine that instantly generates production-ready APIs directly from your database schema — no manual API code required. Connect Hasura to a PostgreSQL database and within seconds you have a full GraphQL API with queries, mutations, and real-time subscriptions for every table and relationship in your schema. For Nigerian developers and startups who want to move quickly without writing repetitive CRUD API boilerplate, Hasura is one of the most powerful productivity tools in the modern backend development toolkit. Nigeria's startup ecosystem is characterized by small, fast-moving engineering teams that need to ship working products quickly while managing limited engineering resources. Building a backend API from scratch — designing endpoints, writing database queries, handling authentication, implementing pagination, and maintaining the code — takes significant time that could be spent on product differentiation and user experience. Hasura eliminates the most repetitive parts of this work, letting Nigerian developers focus on what makes their product unique. The core feature is automatic GraphQL API generation. When Hasura connects to a PostgreSQL database, it immediately exposes GraphQL queries (for reading data), mutations (for creating, updating, and deleting data), and subscriptions (for real-time data streaming) for every table. Relationships between tables are automatically reflected as nested GraphQL types — a users table with a related orders table can be queried in a single GraphQL request that returns users with their nested order arrays, with automatic SQL JOIN generation. Row-level permissions are one of Hasura's most important security features for Nigerian applications. Rather than implementing authorization logic in application code, permissions are defined in Hasura's console as rules: "A user can only read their own rows," "An admin can read all rows," "Guests can only read published records." These rules are enforced at the database query level, making it extremely difficult to accidentally expose data that should be private — a critical security guarantee for Nigerian fintech and health tech applications handling sensitive user data. Real-time subscriptions use WebSocket connections to stream data changes to clients. When a Nigerian analytics dashboard needs to update in real time as new orders come in, or when a chat application needs to display messages as they are sent, Hasura's subscriptions push updates to connected clients automatically without polling. This eliminates the need for Nigerian developers to build WebSocket server infrastructure and manage pub/sub systems. Event triggers allow Hasura to call external webhooks when database operations occur — when a new user is inserted, trigger an email welcome sequence; when an order is updated, notify the logistics system. This event-driven architecture enables Nigerian developers to build complex workflows without tightly coupling services. Hasura is self-hostable via Docker (free) or available as Hasura Cloud with a generous free tier of 60 requests per minute and 1 million operations per month. Hasura's Remote Schemas feature allows federating external GraphQL APIs into the Hasura gateway — making a unified GraphQL endpoint that combines database data with external API data in a single query. Nigerian applications that need to combine PostgreSQL data with third-party API responses can use Remote Schemas to build a unified data layer that resolves all queries from one endpoint. Hasura's event triggers fire webhooks on specific database operations (INSERT, UPDATE, DELETE on specified tables), enabling event-driven architectures where database changes automatically trigger downstream processes — sending notifications, updating caches, or initiating workflows. Nigerian fintech and e-commerce applications can use event triggers to ensure that every significant data change automatically propagates to all dependent systems reliably.
