Website to CRM
The enquiry lands as a lead, assigned and timestamped, with the source recorded so you know which page produced it.

Your systems already talk. Just not to each other.
Most businesses do not need new software. They need the four tools they already pay for to stop being four separate places where the same customer gets typed in by hand.
Short answer
API integration connects two systems so data moves between them automatically — a website enquiry creating a CRM lead, a payment confirming an order, stock syncing from a supplier, a WhatsApp message sending on a status change. It is usually the cheapest improvement available to a business, because the software is already bought.

01 The premise
The cheapest improvement most businesses can make.
A typical small company runs a website, a CRM or a spreadsheet, an accounting package, a payment gateway and WhatsApp. Every one of them is paid for, and in most cases none of them know the others exist. A customer who enquires online is typed into the CRM by hand, typed into the invoice by hand, and messaged by someone copying a number off a screen.
That retyping is not merely slow. It is where errors enter — a digit dropped from a phone number, a name spelt two ways, an enquiry that never made it across because somebody was on leave. The cost is invisible precisely because it is spread across everybody’s day.
Integration removes it, and it is usually a small piece of work relative to its effect, because you are not buying new software. You are connecting what you already own. It is the first thing I look at when a business tells me their operations feel chaotic.
02 Common work
The integrations people actually need.
Roughly in the order they get asked for.
Payment gateways
Razorpay, PayU, CCAvenue or Stripe, with the order confirmed by webhook rather than by trusting the browser.
Payment Gateway IntegrationWhatsApp Business API
Automatic confirmations, status updates and reminders on the channel Indian customers actually reply on.
WhatsApp AutomationAccounting and invoicing
Orders becoming invoices without re-entry, and payment status flowing back the other way.
Supplier and inventory feeds
Stock, pricing and availability pulled on a schedule rather than updated by hand from a spreadsheet.
Ads and analytics
Conversions sent back to Google and Meta, including offline sales, so the platforms optimise on money rather than form fills.
Conversion Tracking03 Reliability
What separates an integration that lasts.
Anyone can make an API call succeed once. These are what stop it failing silently in month four.
Built in
- Retries with backoff. Third-party APIs go down. A failed call is retried rather than lost, with increasing gaps so you do not make the outage worse.
- Idempotency. The same event arriving twice must not create two leads or two invoices. Duplicate handling is designed in, not discovered later.
- Error logging and alerts. When something fails repeatedly, somebody is told. Silent failure is the normal way integrations die.
- Credentials stored properly. Outside the web root, never in the repository, revocable without a code change.
- Rate-limit awareness. Respecting the limits the provider publishes, so your account is not throttled or suspended at the worst possible moment.
- A manual fallback. A way to re-send or re-sync by hand when something has gone wrong. You should never be stuck waiting for me.

04 Process
How an integration gets done.
Map the flow
What triggers it, what data moves, what the receiving system needs, and what should happen when it fails. The failure case is the part usually skipped.
Check the APIs
What each side actually supports, its rate limits and its authentication. Occasionally this reveals the integration cannot work as imagined — far better known now.
Build and log
Written with logging from the start, so behaviour is observable rather than inferred.
Test the failures
Not just the happy path. Wrong credentials, timeouts, duplicate events, malformed data — each exercised deliberately.
Monitor
Alerting on repeated failure, plus a note explaining how to re-run something by hand.

API integration — your questions.
Straight answers, including the ones that cost me work. If yours is not here, ask it — I reply the same day.
A well-documented one-way integration — website enquiry into a CRM — is often a few days. Two-way synchronisation with conflict rules takes longer, because deciding which system wins when both have changed is a business decision, not a technical one.
Then the options narrow: a scheduled file export and import, a database-level connection if you control it, or occasionally screen-level automation, which I recommend only as a last resort because it breaks whenever the interface changes. I will tell you honestly which of these you are looking at.
Yes, through the official WhatsApp Business API. Message templates need Meta approval before they can be sent, which is a real factor in the timeline. I will not build anything using unofficial methods, because they get numbers banned.
Providers deprecate versions periodically, usually with notice. Sensible integrations pin a version and log clearly when something starts failing, so a change is caught quickly. Under a maintenance arrangement I watch for those announcements; without one, the logging still tells you.
It is more secure than the alternative, which is usually people emailing spreadsheets to each other. Credentials are stored outside the web root, never committed to the repository, scoped to the minimum permission needed, and revocable without touching code.
Yes. An API is a contract over HTTP and the language on either side is irrelevant. What matters is the quality of the documentation, not the technology.
