How much does custom API development cost?

A straightforward integration between two systems typically starts around ₹40,000, while a custom API built from scratch with multiple endpoints, authentication, and documentation can range from ₹1,50,000 to ₹6,00,000+, depending on complexity. We quote after understanding exactly what needs to connect.

Can you integrate with the specific software our business already uses?

In most cases, yes. If the platform has a public API — which most modern CRMs, payment gateways, and business tools do — we can build the integration. For older or more obscure systems, we assess feasibility during discovery before quoting.

How long does it take to build a custom API or integration?

A single integration between two well-documented platforms usually takes 2–4 weeks. A custom API built from scratch, or an integration involving multiple systems and complex business logic, typically takes 6–10 weeks.

What happens if a third-party platform changes their API?

Third-party APIs do change or get deprecated over time, which is exactly why ongoing monitoring matters. We track the platforms you're integrated with and update your integration when they release breaking changes, so it doesn't fail silently and disrupt your operations.

Is our data safe when it moves between systems through an API?

Yes. We implement encryption, authentication, and access controls on every API and integration we build, and follow the security requirements specific to sensitive data like payments or personal information.

Do you provide documentation and support after the API is delivered?

Yes. Every API comes with clear documentation, and we offer ongoing maintenance plans covering monitoring, updates when connected platforms change, and support if something in the integration chain breaks.

Who We Are – API Development & Integration Company for Growing Businesses

Most businesses aren't short on software — they're short on software that talks to each other. A CRM that doesn't sync with your accounting tool, an eCommerce store that needs manual order exports, a mobile app waiting on data that lives in three different systems. At Auraveni Solutions, we build the APIs and integrations that connect what you already have, and design new APIs for software that doesn't exist yet.

We build custom REST and GraphQL APIs, and integrate with the platforms your business already runs on — payment gateways, CRMs, ERPs, logistics providers, and other third-party services — testing and documenting everything in Postman along the way. Every API we build comes with authentication, rate limiting, and error handling done properly from the start, not bolted on after something breaks in production.

An API is invisible when it works and expensive when it doesn't — a broken integration can quietly cost you orders, data, or hours of manual reconciliation before anyone notices. We build with that in mind: documented, monitored, and hosted on infrastructure built to stay up, so failures happen loudly, not silently.

We proudly serve clients across a wide range of industries, including:

Agriculture

Healthcare & Clinics

eCommerce & Retail

Education & eLearning

Hospitality & Travel

Real Estate & Construction

Corporate & Enterprises

Manufacturing & Industrial

Technology & Startups

Automotive

Food & Beverages

Government Service

Logistics

Legal, Financial & Consulting Services

Salons, Spas & Wellness Centers

Warehousing

If your team is manually exporting data between systems, re-entering the same information twice, or waiting on a developer every time two tools need to connect — that's exactly the kind of problem an API solves.

Custom API or a No-Code Tool Like Zapier — Which Do You Need?

Tools like Zapier and Make can connect two apps in an afternoon, and for a lot of businesses, that's genuinely enough — you don't always need custom development. The trouble starts when those tools get stretched past what they're built for. Here's how to tell which side of that line you're on.

A no-code tool works fine if you...

Are connecting two popular, well-supported apps
Have low data volume and simple, occasional syncs
Are validating a workflow before investing further
Don't need custom logic, validation, or error handling

Custom API

Custom API development makes sense if you...

Need to integrate with a system that doesn't have a ready-made connector
Are moving high volumes of data or need real-time syncing
Are paying escalating per-task fees as automation volume grows
Need control over exactly how data is transformed, validated, or secured

Not sure which side you're on? Tell us what you're trying to connect and how often — we'll tell you honestly if a no-code tool will do the job, or if it's time for something built specifically for your systems. For a longer look at planning this out as you grow, read our guide on API integration strategy for growing businesses.

Our Services

API work covers more than "connecting two apps" — it's building new APIs from scratch, integrating with platforms you already use, and keeping everything running once it's live. Here's the full range of API development and integration services we offer.

Custom API Development (REST & GraphQL)

APIs Built From Scratch Around Your Data and Logic

We design and build custom REST and GraphQL APIs for your web or mobile application, structured around your actual data model and business rules rather than a generic template. Often built alongside our custom software development work.

Third-Party API Integration

Connecting Your Software to the Platforms You Already Use

We integrate your systems with payment gateways, CRMs, ERPs, shipping and logistics providers, and other third-party platforms, so information moves automatically instead of being re-entered by hand.

Legacy System API Integration

Connecting Older Systems That Were Never Built to Share Data

We build bridge APIs and middleware that let legacy or internal systems exchange data with modern platforms, without requiring you to rebuild the older system itself.

API Security & Authentication

APIs Secured the Right Way From the Start

We implement authentication, authorization, rate limiting, and encryption on every API we build, reducing the risk of data exposure or abuse instead of adding security as an afterthought.

API Documentation

Documentation Your Team Can Actually Use

Every API we deliver comes with clear, structured documentation covering endpoints, parameters, and example requests, so your developers — or ours, later — aren't reverse-engineering how it works.

Webhooks & Real-Time Data Sync

Data That Updates the Moment Something Changes

We set up webhooks and event-driven integrations so your systems reflect changes in real time — a new order, a status update, a payment — instead of relying on scheduled syncs that lag behind.

API Performance Optimization

Faster APIs That Don't Slow Down Your Application

We audit and optimize existing APIs for response time, database query efficiency, and caching, fixing the slow endpoints that quietly drag down your application's overall performance.

API Maintenance & Monitoring

Keeping Integrations Running After They Go Live

We monitor API uptime and performance, handle version updates when third-party platforms change their APIs, and fix integration failures before they turn into missing orders or broken workflows.

How We Build & Integrate Your APIs

From mapping out what needs to connect to what, to the monitoring that catches problems after launch, we follow a structured process built for APIs that keep working long after the initial build.

Auraveni Solutions builds APIs that keep quietly doing their job — even when the platforms on the other end update, change, or need replacing.

FAQ

An API (Application Programming Interface) is the set of rules that lets two pieces of software communicate. An integration is the actual connection built using one or more APIs to make two specific systems work together — for example, connecting your website's checkout to a payment gateway's API.
