API integration & development.

Your business data lives in systems that were never introduced to each other. We build the connections and the interfaces on top: front ends fed by live data, systems that sync instead of being retyped, and APIs of your own when you need one.

The problem & the fix

Systems that refuse to talk.

The problem

The CRM knows the customer, the ERP knows the stock, the website knows neither, and a person spends afternoons ferrying data between them. Every manual hop adds delay and a chance to mistype.

Our solution

We connect the systems through their APIs and build clean interfaces on the live data. Orders flow to accounting on their own, the website shows real stock, and the afternoons come back.

List the systems that should talk but do not. We will map the connections.

What we do

API services.

Connections, interfaces, and the plumbing between them.

Third-party integrations

CRMs, payment gateways, ERPs, courier systems, and marketing tools connected to your site or app.

API-driven front ends

Fast interfaces on React and Next.js that read and write live data from whatever runs your business.

Data synchronization

Two-way syncs that keep systems agreeing about customers, orders, and stock, with conflicts handled sanely.

Custom API development

REST and GraphQL APIs of your own, documented, versioned, and ready for partners or mobile apps.

Webhooks & automation

Events that trigger actions across systems, an order placed here, an invoice raised there, untouched by hand.

Reliability & monitoring

Retries, alerts, and logging, because an integration that fails silently is worse than none.

Not sure which of these you need? We will map it with you in a free call.

Ways to work with us

Three doors into API integrations.

The API integrations work is scoped together first, then quoted in writing.

Ongoing retainer

Best forTeams that need API integrations handled every month without chasing anyone.
PricingA monthly block of API integrations hours at a rate agreed once.
TimelineThe API integrations retainer rolls month to month. Stop with 30 days notice.
IncludesA monthly summary of the API integrations done and direct chat with the person doing it.
Talk retainers

Quick task

Best forOne task at a time: a broken sync, a new endpoint or a rate limit issue.
PricingOne small quote per API integrations job, agreed first.
TimelineUsually days, not weeks, for small API integrations jobs.
IncludesA short before and after API integrations summary.
Send the task

Start small on API integrations if you want. Most clients do.

Five commitments behind API integrations.

Five things you can hold us to on API integrations.

01Agreed cost upfrontThe API integrations scope and price are fixed before anything starts.
02Ownership stays with youAccounts, files and API integrations access sit under your name throughout.
03Confidentiality firstOne signature and your API integrations information is covered.
04We fix our own missesThe first 30 days of fixes on our API integrations cost you nothing.
05The doer answers youThe person you brief on API integrations is the person who delivers.
Why choose GAP3

Why our integrations stay connected.

Anyone can call an API once. The craft is in what happens when it fails at 2 a.m.

Built for failure days

Retries, queues, and alerts mean a provider outage becomes a delay, not a data loss.

Data stays reconciled

Sync rules are explicit about which system wins, so records never quietly drift apart.

Documented flows

Every connection is diagrammed and documented, so it is maintainable by any team, forever.

Fast on the front

The interfaces on top of the data stay quick, cached sensibly, and honest about loading states.

Honest sizing beats a sales pitch: micro API integrations jobs go to freelancers, giant programs to giant agencies, the rest to teams like ours.

Integration work fits when.

FAQ

API questions, answered.

Connecting two systems so they exchange data automatically: your website to your CRM, your store to your accounting, your app to a payment gateway. The manual retyping between them disappears.

Anything with an API, and most modern software has one: CRMs, ERPs, payment gateways, courier services, marketing platforms, and custom or legacy systems. File-based exchanges work as a fallback for the stubborn ones.

Yes. Stock levels, pricing, availability, and account data can render live on your site through a fast API-driven front end.

With our builds, the work queues and retries, an alert fires, and nothing is lost. Designing for the failure case is most of the engineering.

Yes. REST or GraphQL, versioned and documented with Swagger, ready for partners, mobile apps, or your own future front ends.

Explicit rules about which system owns each field, idempotent updates, and reconciliation checks that flag drift instead of letting it accumulate.

Yes, when built properly: scoped keys, encrypted transport, secrets managed outside the code, and access logged. We treat integration credentials like the master keys they are.

A single well-documented API connects in days to a couple of weeks. Multi-system syncs with edge cases take longer, and the mapping phase tells us which before you commit.

A fixed quote per connection or project. Weigh it against the daily hours of retyping it removes; integrations usually clear that bar quickly.
