API Development

API development and integration

Clean connections between your systems so data stops being copied by hand between them.

The problem

An order comes in on your website. Someone reads it, opens your accounting software, and types the line items in again. At the end of the day someone else opens the logistics system and types the delivery address in for the third time. This is not a people problem — your team is doing exactly what the systems require. It is a connection problem: the systems do not know about each other, so a human has to carry the information between them. An API is a connection point. When systems have them, data can move on its own.

An order placed in one system appears correctly in every other system that needs to know about it.

Built for: Teams whose data exists but lives in the wrong place at the wrong time.

What we deliver

  • Clean documented endpoints. Every API we build ships with documentation that describes what each endpoint expects, what it returns, and what the error responses mean. An undocumented API is one the next developer cannot safely use.

  • Webhooks for real-time events. When something happens in one system, the other systems that care about it hear about it immediately — not on the next scheduled import.

  • Versioning and rate limits. Changes to an API do not break the systems already using it. Rate limits prevent one runaway process from taking everything else with it.

  • Integrations with what you run. Zoho, Tally, Razorpay, Shiprocket, Google Sheets, WhatsApp — we connect the tools your business is already on rather than asking you to replace them.

Frequently asked questions

What is an API in plain terms?
An API is a defined way for two pieces of software to talk to each other. When your payment gateway tells your database that a payment cleared, it does that through an API. We build and connect those endpoints so the conversation happens automatically instead of via a person copying a number from one screen to another.
Can you integrate with Indian systems like Tally or GST portals?
Tally has an XML import mechanism we can write to. For GST, we can connect to the GSTN sandbox for filing and validation flows. Where official APIs exist, we use them; where they do not, we use the import formats the system supports.
What if the system we need to connect to does not have an API?
It depends on what the system exposes. Many older tools have CSV imports, webhook receivers or file-drop integrations even without a full API. We look at what is available before concluding that an integration is not possible.
