Connections
API and third party integrations
Most businesses already run four or five systems. The website should talk to them rather than become a sixth.
The website collects an enquiry. Sales works in a CRM. Accounts works in Tally. Delivery works in a courier dashboard. If those four do not talk, somebody spends their morning copying between them, and that person will eventually mistype something that matters.
Integration work is mostly about the unhappy path. Any developer can call an API when it responds correctly. The value is in what happens when it times out, returns a shape nobody documented, or succeeds twice for the same order.
So we build retries, we make writes safe to repeat, we log every exchange, and we make failures visible instead of silent.
What the work covers
Included in every api integrations project.
Payment gateways
Razorpay, Stripe, PayU, Cashfree and UPI. Confirmed by server side webhook, because a browser redirect is not proof that money moved.
CRM and sales tools
Enquiries pushed into HubSpot, Zoho, Salesforce or a sheet, with the source and campaign attached.
Messaging
WhatsApp Business API, SMS gateways and transactional email, with templates approved and delivery tracked.
Maps and location
Store locators, service area checks and route previews. Keys proxied through our own route so they are never printed in your page source.
ERP and accounting
Stock, pricing and invoice sync where an API exists, scheduled file exchange where it does not.
Failure handling you can see
Retries with backoff, a dead letter record for anything that never succeeded, and an alert rather than silence.
No themes, no page builders, no plugin stacks
Every site written from scratch, starting from almost nothing and adding only what the pages need. The whole speed recipe is published, not kept secret.
Read the recipe →AI, used properlyWe use AI to go faster, not to decide
It writes the mechanical parts. It never chooses the architecture, the performance budget, or a single fact about your business. Everything is reviewed by the person who will maintain it.
Where we draw the line →Questions
Asked often enough to answer here.
If yours is not here, the general questions page covers how we work, or you can just ask.
Our software has no API. Can you still connect it?
Usually. Scheduled CSV or Excel exchange over SFTP or email handles a surprising amount of real business integration. It is less elegant and it works. We would rather ship that than sell you a rewrite of software that is doing its job.
Who pays for the third party services?
You do, directly, in your own accounts. We set them up and hand over the credentials. Billing that runs through an agency is a problem the day you change agency.
How do you test a payment integration safely?
Sandbox credentials first, covering success, failure, timeout and duplicate callback. Then a small live transaction end to end before launch, refunded afterwards.
