SERVICES / TEAMS & SCALE · API INTEGRATIONS

API Integrations

Payments, social media, CRM, fulfilment, telephony — anything with an API, wired into your product so it stays wired in. Two rails are home ground: Stripe, PayPal, ChargeBee and Clover on the payment side, and Facebook, Instagram, TikTok, X, LinkedIn, Pinterest and Snapchat on the social side — all shipped into production.

The free 30-minute session maps the systems that should talk in your operation, and the honest order to connect them. You keep the map either way.

Integration debt, as buyers describe it

N-01

The systems that should talk, don’t

Orders in the store, stock in the ERP, customers in the CRM — moved between them by people, on schedules, with mistakes. Every un-integrated seam is a re-typing job someone does forever.

N-02

The payment integration was built for the happy path

It works until a webhook is missed, a refund is partial, or a customer retries a timeout — then the books and the provider disagree. Payment integrations are where idempotency and reconciliation stop being theory and start being money.

N-03

A provider changed its API and broke the quarter

Versions deprecate, fields rename, rate limits tighten. Integrations without monitoring and without an owner degrade silently — the failure is discovered by a customer, not a dashboard.

N-04

Zapier connects it, until volume arrives

No-code connectors are honest prototypes, and they buckle at volume: no retries, weak error handling, per-task pricing that scales badly. Graduating the load-bearing flows to engineered integrations keeps what worked and removes what wobbles.

Every un-integrated seam is a human doing a machine’s job on a schedule. The map of your seams is a map of recoverable payroll.

02Deliverables, not adjectives

What we wire in

Payments and billing

Stripe, PayPal, ChargeBee and Clover — checkouts, subscriptions, refunds, disputes and webhooks, with idempotent writes and reconciliation views, because payment integrations are accounting systems in disguise.

You get: money flows your books can trust, provider hiccups included.

CRM, catalogue and fulfilment

Customers, products, orders and shipments flowing between store, ERP, CRM and logistics — the seams where staff currently re-type.

You get: records that move themselves, with an audit trail.

Social media APIs

Facebook, Instagram, TikTok, X, LinkedIn, Google, Pinterest and Snapchat — publishing, scheduling, media upload and analytics read-back, with the OAuth token refresh, per-network rate limits and per-network media rules handled where they belong. We built a multi-tenant social publishing platform on more than ten of these APIs and took it from an empty repository to mass adoption.

You get: one scheduling and campaign engine that speaks every network.

Messaging and telephony

WhatsApp Business, Telegram, Slack, Discord and Twilio — notifications, two-way conversations, verification codes and support handoffs, with delivery receipts read back into your own system and template approval handled where each platform asks for it.

You get: the channels your customers already use, wired to the product rather than to a person.

Anything with an API

Maps, accounting, marketing platforms, partner systems — the discipline is identical: contracts, retries, monitoring, documentation.

You get: integrations built to the same standard whatever the logo.

The reliability wrapper

Retries with backoff, idempotency keys, dead-letter queues, rate-limit respect and alerting — the unglamorous 40% that separates integrations that last from integrations that demo.

You get: flows that survive provider outages and tell you when they could not.

03The path, with dates

How it works

STEP 01

Map the seams

Which systems should talk, what data crosses, who owns each side — and the order that pays back fastest.

week 1
STEP 02

First seam closed

The highest-pain integration built with the full wrapper — retries, idempotency, monitoring — and verified against real traffic.

weeks 2–4
STEP 03

Seam by seam

Remaining integrations land in priority order, each documented and monitored from day one.

weeks 4–10
STEP 04

Own the estate

Version watches, deprecation handling and monthly health checks — integrations need an owner, and we stay on as one where wanted.

The order matters

Integrations pay back in a sequence: the seam bleeding the most money first. We rank them before we wire them.

05Book a call

Close the most expensive seam first

One 30-minute session maps your systems and ranks the seams by payback. The first integration is scoped in writing, priced before it starts, and shipped with the full reliability wrapper — never happy-path-only.

If a no-code connector genuinely covers a seam, we say so — engineering is for the load-bearing flows.

Month-six test

Demos test the happy path; month six tests the retries. We build for month six on day one.

The wrapper · 60 seconds
07Asked before buying

The questions buyers actually ask

Which payment providers have you integrated?

Stripe, PayPal, ChargeBee and Clover in production, plus licence-verification and payout flows around them. The pattern — webhooks, idempotency, reconciliation, disputes — transfers to any provider on your shortlist.

What makes a payment integration hard?

It is an accounting system in disguise: missed webhooks, partial refunds and customer retries all create money states your books must agree with. We build idempotent writes and reconciliation views from day one, because finding a mismatch in month six costs far more than preventing it.

Can you take over integrations that already exist?

Yes — starting with a read of their failure modes: what happens on timeout, on duplicate, on provider outage. The usual finding is missing wrapper, not wrong logic, and the wrapper can be retrofitted without a rebuild.

When is Zapier or Make good enough?

For low-volume, non-critical flows — genuinely good enough, and we say so. The graduation point is volume, money or customer-facing consequences; load-bearing flows deserve retries, monitoring and version control.

How do you handle provider API changes?

Version watches and deprecation alerts as part of the monthly ownership model, with changes shipped through the same tested pipeline as the original build. Integrations rot without an owner; the ownership is the service.

What does an integration cost?

Scoped per seam, in writing, after the free mapping session — with the reliability wrapper included in the number, not sold back to you later as hardening.
