Connect your business systems with reliable integrations

When your systems do not talk to each other, staff can end up copying customer, booking, order or accounting information between platforms. A well-designed integration can move the right data while keeping errors and interruptions visible.

When systems do not communicate

Stop relying on people to keep separate platforms aligned.

Manual CSV exports, copied order details and customer records maintained in several places create delay and uncertainty. A website enquiry may need to enter a CRM, booking data may need to reach an operational system, or accounting information may need to follow an order without being typed again.

Integration discovery starts with the business flow: which system owns each piece of information, where it needs to go, when it should move and what should happen when the data is incomplete or a service is unavailable.

The technical route may then use an available API, webhook, scheduled synchronisation or another proportionate exchange method. If the core problem is the wider sequence of tasks and decisions, business process automation may be the better starting point.

01

Define the source of truth

Agree where each record is owned so updates do not create competing versions or unclear responsibility.

02

Map data in business terms

Identify what each field means, which values are required and how information should be transformed or validated.

03

Plan for interruption

Decide how failures, duplicate events, expired access and partial updates should be detected and recovered.

Potential integration requirements

Move useful information without losing control of it.

These are examples of possible integration work, not claims about previous API projects or a fixed list of supported platforms.

01

CRM and customer data

Pass relevant enquiries, contacts, status changes or activity between a CRM and the other systems involved in the customer journey. Explore bespoke CRM development →

02

Orders and product information

Synchronise suitable order, product, stock or fulfilment data between websites and operational platforms where access permits.

03

Booking and operational systems

Move booking details, availability changes or customer actions between calendars, booking software and operational tools. Explore booking systems →

04

Accounting and payments

Connect relevant financial events or payment outcomes while keeping ownership, reconciliation and compliance responsibilities clear.

05

Imports, exports and data feeds

Replace an appropriate manual file transfer with a validated scheduled exchange when real-time movement is unnecessary.

06

Third-party services

Assess the available interface, permissions, limits and reliability before connecting a specialist platform to the wider business workflow.

From data flow to dependable operation

Reliability is part of the integration.

A successful request is only the happy path. Authentication, invalid data, duplicate events and third-party outages also need deliberate behaviour.

  1. 01

    Review systems and access

    Confirm available APIs or exchange methods, permissions, limits, documentation and the data each platform owns.

  2. 02

    Design the data flow

    Map fields, authentication, validation, direction, frequency and whether updates should be real-time or scheduled.

  3. 03

    Build and test failures

    Handle retries, duplicate events, expired access, invalid responses and interrupted synchronisation as appropriate.

  4. 04

    Monitor and maintain

    Use logging and alerts to make problems visible, then support changes when a connected platform evolves.

Native connection or bespoke integration

Use an existing integration when it solves the requirement reliably.

A maintained native connector or suitable automation platform may provide the required data flow with less custom code and ongoing responsibility.

Bespoke API integration becomes worth exploring when the data mapping, business rules, scale, controls or failure behaviour cannot be handled proportionately by an existing option.

When healthy systems are not enough

An integration should respond appropriately when:

  • A third-party API is unavailable or a request times out.
  • Authentication expires or permissions change.
  • Invalid, incomplete or unexpected data is received.
  • An event is repeated or synchronisation is interrupted part-way through.

Integration questions

Start with the systems and the information that needs to move.

You do not need to define the technical approach. The current manual work, platforms and required outcome provide the useful context.

Discuss an integration
What information is useful for an initial integration discussion?

The names of the systems, the information copied today, which platform should own it, how quickly it needs to move and what currently goes wrong are useful starting points. Credentials should not be sent in an initial enquiry.

Does data need to synchronise in real time?

Not always. Real-time updates may be important for availability or immediate actions, while scheduled synchronisation can be simpler and more appropriate for reporting or lower-priority data.

What if one of the systems does not have an API?

Other supported export, import or data-access options may be assessed. Feasibility, security, reliability and the platform's terms need to be understood before a route is recommended.

How are authentication and permissions handled?

The approach depends on the connected platform. Access should use the permissions needed for the agreed data flow, with credentials and renewal responsibilities handled securely and documented clearly.

What happens when an integration fails?

Appropriate retries, logs, alerts and recovery behaviour are designed around the importance of the data. Failures should be visible rather than silently leaving systems out of sync.

Would a native integration be better?

Often, yes. If a maintained connector handles the required fields, timing, rules and reliability, bespoke development may be unnecessary. The alternatives should be assessed before custom work is proposed.
