API integration services that connect the systems your business already runs on.

An integration is code that authenticates against someone else’s system, sends a request in the format that system expects, handles the answer including the failures, and stores the result where your team can see it. The part that takes time is not the happy path. It is the retry when the gateway times out, the webhook that arrives twice, and the response that changes shape when the courier has no serviceable pincode.

What it is not: installing a plugin and ticking a box. A plugin works until the API version changes or a call fails quietly, and then the payment is captured but the order was never marked paid, and nobody finds out until a customer complains.

Times and prices below are the ones published in the table further up this page, not indicative ranges.

One API connected end to end is ₹10,000 one-time. Three together, usually payments plus SMS plus WhatsApp, are ₹25,000. Unlimited integrations with custom workflow automation are ₹50,000. Support runs 1, 3 and 6 months in that order, and after it a maintenance retainer is ₹5,000 a month per integration.

Very little of that goes into the code that makes the first successful call, which is often an afternoon. It goes into sandbox testing against the provider’s test credentials, retry and error handling, webhook verification so a replayed message cannot charge a customer twice, and the handover document that tells the next developer what exists. A quote far below this is usually skipping the last three.

WhatsApp is the price people question. It is higher because most of the work is not code: a Business Solution Provider account (AiSensy, Interakt or Gupshup), Meta business verification, and message template approval, each of which involves waiting on someone else.

You are handing over credentials that can move money and message your customers. Four things should be true before that happens, whoever does the work.

The first call is short and mostly questions. Which systems, which direction the data flows, what should happen when one of them is down, and who sees the error when it does. From that we can usually say on the same call whether this is a two-day job or a two-week one.

Plugin-shaped work on WordPress or Shopify sits at the fast end. Anything that reconciles two sets of records, orders against a ledger for instance, sits at the slow end, because the difficult part is deciding what the system does when the two disagree. We also work on codebases we did not build, including WordPress, Shopify, custom React and Next.js, PHP, Webflow and Bubble, as long as there is admin or repository access.

Three cases where we would tell you to keep the money.

The manual step happens five times a week and takes two minutes. The automation will cost more than the time it saves for years. Write the process down instead and revisit it when the volume grows.

The system you want connected has no public API. The only routes left are scraping or a script clicking through the interface, and both break the day the vendor moves a button. We would rather say that than build something you pay us to repair every quarter.

Your data is wrong in the source system. An integration spreads that error faster, not slower. Clean the records first; an automated pipeline pushing bad phone numbers into an SMS gateway only buys the mistake at scale.

Working code is half the delivery. The other half is a document listing every endpoint used, the credentials required and where they are stored, the webhook URLs registered with each provider, and what each error code means when it turns up in the log. A training session goes with it, so your team knows where to look when something fails, plus whatever support window came with the package.

Credentials stay in your accounts, registered to your business email rather than ours. If you move to another developer, nothing has to be rebuilt just to get you access.
