Custom API Development
Custom APIs and integrations that connect your website, app, billing, payments and internal tools — so data moves automatically instead of someone retyping it every evening.
What we build
Endpoints built for your business logic, with authentication, versioning and proper error handling.
Razorpay, UPI, payment links, subscriptions and webhooks that reconcile correctly with your records.
Order confirmations, reminders and alerts sent automatically from your own system.
Move orders and invoices from your website into Tally without manual entry.
Amazon, Flipkart, Meesho, Shopify and WooCommerce — keep stock and orders in step across channels.
The API layer your Android or iOS app talks to, including authentication and push triggers.
Event-driven flows so one action in a system triggers the right response in another.
Older software with no modern API? We build a layer around it rather than replacing what works.
One-time migrations or scheduled syncs between databases, spreadsheets and platforms.
What you receive
Custom Quote
API work is priced by the number of systems involved and how cooperative each one is. Tell us what you want connected and what you're doing manually today, and we'll scope it properly before quoting.
How we work
What data exists where, and what should happen automatically instead of manually.
We confirm each system can actually do what's needed, before any commitment.
Structure, authentication and failure behaviour agreed with you in writing.
Developed against staging, tested with real cases including the ones that go wrong.
Go live, with documentation, credentials and a walkthrough for your team.
Questions
Not always. Some systems support scheduled exports, database access or file drops that we can build around. We check first and tell you honestly if it isn't workable.
You do, on final payment, along with the documentation. We reuse our own general-purpose libraries across projects, but what's built for you is yours.
Integrations occasionally break when a provider updates. If you're on a care plan we handle it as part of the plan; otherwise we quote the fix.
Credentials are stored securely and never in code repositories, connections use HTTPS, and access is limited to what each integration actually needs. We can also work under an NDA.
Yes. We're often brought in specifically for an integration alongside an in-house team, and the documentation is written for exactly that situation.
A single straightforward integration is usually one to two weeks. Multi-system projects depend on how quickly access and credentials come through.
Most growing businesses end up running several systems that don't know about each other — a website taking orders, a billing package, a spreadsheet for stock, and a WhatsApp number where customers actually ask questions. Somebody spends an hour a day copying between them, and mistakes creep in at exactly the points that cost money.
Custom API work removes that copying. Once systems can pass data directly, an order placed online can raise an invoice, update stock, and send a WhatsApp confirmation without anyone touching it.
ZenoraTech builds integrations and custom APIs for small and medium businesses in Tiruchirappalli and across Tamil Nadu, and remotely for clients elsewhere in India. Related services: web application development, business automation, payment gateway setup and Tally & GST automation.
Describe the task someone repeats every day. That's usually where an integration pays for itself first.
