Can a system with no API still be integrated?

Often, yes. A system without an API can usually be connected through file exports, direct database access or careful automation of its interface, and CoreFinity Tech confirms which route is reliable before quoting.

Who pays for third party API costs in an integration project?

The client pays third party API costs directly, billed to the client's own accounts. CoreFinity Tech sets up every service in the client's name so the client controls the keys, the spending and the vendor relationship.

What happens when a third party API changes?

API providers deprecate endpoints with varying notice, so CoreFinity Tech builds integrations that detect and report breakage immediately instead of letting data go missing for weeks.

Can CoreFinity Tech fix an integration built by someone else?

Usually, yes. CoreFinity Tech diagnoses why the existing integration fails and recommends repairing or replacing it based on value.

Systems Integration: Make your systems talk to each other.

Two way connections across payments, CRMs, messaging, calendars and databases.

Talk to an engineer

Businesses rarely run on one system. They run on a payment provider, a CRM, an accounting package, a booking calendar and a messaging channel, none of which were designed with the others in mind.

The gap between them is usually filled by a person with a spreadsheet. Integration work closes that gap, which is both cheaper than the person and considerably less error prone.

( What this covers )

Systems Integration, in practice

Payment gateways

Stripe and regional providers, including subscriptions, refunds, settlement reconciliation and the webhook handling that keeps records straight.

CRM connections

Leads, contacts and deals synchronised automatically, so your sales system reflects reality without anyone updating it.

WhatsApp and messaging

Order confirmations, reminders and notifications through the channel your customers actually read.

Calendar synchronisation

Two way iCal sync so availability stays correct across every channel you sell through, and double bookings stop happening.

Database integration

Connecting systems that hold overlapping data, with a clear decision about which one is the source of truth.

Custom API work

Building the API your partners need, or consuming one that is badly documented, which is most of them.

( Worth talking to us if )

Any of this sounds familiar.

The same information is entered into two systems by hand
Your booking availability is wrong across channels
Payments reconcile manually at the end of every month
A supplier or partner has an API and nobody has connected it
An existing integration breaks regularly and nobody knows why

( How we work )

The shape of a typical build

01
Map what exists
Which systems hold what, where they disagree, and which one should win when they do.
02
Design the flow
Direction, frequency, and what happens on conflict. Two way sync without conflict rules causes more problems than it solves.
03
Build with failure in mind
Retries, idempotency and alerting, because third party APIs go down and yours should survive it.
04
Verify against real data
Tested with your actual records, not with clean examples that hide the edge cases.

( What you end up owning )

Everything, and no strings.

The integration code and its configuration
Documentation of every flow, including conflict rules
Credentials held on your own accounts throughout
Monitoring so a failed sync raises an alert, not a mystery

( Built with )
