API Integrations and Third-Party Systems
Most API integrations work well in testing but become unreliable in production. Webhooks can fail, APIs can time out or become rate-limited, and third-party systems can change how they return data.
We build integrations that account for these situations from the start. That includes webhook handling, retry logic, CRM and ERP synchronisation, payment gateway integrations, data validation and custom API connections.
The goal is simple: keep the systems your business relies on communicating reliably, even when one of them is temporarily unavailable.
Connections That Work Reliably
Your website or application rarely operates on its own. It may need to communicate with your CRM, ERP, accounting software, payment providers, inventory systems or other business platforms.
We build API integrations around the systems you already use, with appropriate error handling, retries and monitoring where required. If a service becomes unavailable, requests can be queued and retried rather than simply failing.
This reduces the need for manual reconciliation and helps keep important business data consistent across your systems.

What Our API Integration Service Covers
We build integrations around real-world conditions, not just the successful response that works in a development environment.
- Webhook handling and retry logic: Failed deliveries can be retried automatically rather than silently dropped.
- Queued and failed events: Events that cannot be processed immediately can be retained for review and later processing.
- CRM, ERP and payment integrations: Customer, order, payment and business data can be synchronised between the systems you rely on.
- Rate limit and timeout handling: Requests can be throttled, retried and backed off according to the limits imposed by each API.
- Data consistency checks: Integrations can be designed to reduce duplicate records, partial updates and mismatched data between systems.
- Custom API integrations: Where an existing connector is not suitable, we can build a custom integration around the API and workflow your business requires.
Why We Design for Failure
Third-party APIs can become unavailable, return unexpected responses, time out or change their behaviour. A reliable integration needs to account for what happens when a request does not succeed.
We design integrations to handle these situations through appropriate retry strategies, queues, validation and error handling. Depending on the system, failed events can also be logged or flagged for review so they do not disappear without explanation.
This approach is considered as part of the architecture from the beginning, rather than added after an integration has already caused problems in production.
What You Get
- Integrations designed to handle temporary outages, timeouts and rate limits.
- Failed events retained and logged where appropriate, rather than silently discarded.
- Data synchronisation designed to minimise duplicates and inconsistent records.
- Clearer visibility into integration failures and processing issues.
- Less manual reconciliation between business systems.
- Custom integrations built around your existing software and workflows.
The Business Problems This Solves
Poorly handled integrations can create problems that are difficult to spot immediately. An order may fail to reach a fulfilment system, a customer record may not update in the CRM, or a payment may be processed without appearing correctly in another business system.
These issues often end up as manual checks, support requests or time spent investigating what went wrong.
A properly designed integration can automate much of this process, handling temporary failures and making exceptions visible to the right people. The result is less manual administration and more reliable communication between the systems your business depends on.
If your integrations currently rely on manual checks or regularly require someone to fix failed synchronisation, we can review the setup and identify the underlying problems.
THE BUSINESS CASE
Why Robust Integrations Save Time and Money
Poorly designed integrations can create ongoing administrative work, data inconsistencies and avoidable support issues. Reliable integrations reduce the amount of manual work required to keep systems in sync.
Reliable Data Transfer
We design integrations to handle temporary API failures and retry requests where appropriate. When a service is unavailable, data can be retained and processed when the connection becomes available again.
Handles API Limits
Many third-party APIs impose limits on how frequently they can be called. We account for those limits when designing integrations, using appropriate throttling and retry strategies to avoid unnecessary failures.
Consistent Business Data
Customer records, orders, payments and inventory often need to remain consistent across multiple systems. We build synchronisation logic around the specific data and workflows your business relies on.
Less Manual Administration
Automating data transfer between systems reduces repetitive data entry and manual reconciliation. Your team can spend less time moving information between platforms and more time working on the tasks that require their attention.

FAQ
Your API Integration Questions Answered
Connecting different software systems can involve technical constraints, legacy platforms and third-party APIs that you don't control. Here are answers to some of the questions we hear most often.
An API is a way for different software applications to communicate with each other. For example, an API can allow orders from your website to be sent automatically to your accounting, fulfilment or inventory system.
API integrations can reduce manual data entry, keep information synchronised between systems and automate processes that would otherwise require your team to move data between platforms.We design integrations to account for temporary outages and failed requests. Depending on the system, data can be placed into a queue and processed when the service becomes available again.
We can also implement logging and alerts so persistent failures are visible rather than silently leaving data unprocessed.Often, yes. The available approach depends on what the system supports. Some legacy platforms provide APIs, database access or scheduled data exports such as CSV files.
We assess the available interfaces and recommend the most reliable way to connect the system without introducing unnecessary complexity.The timeline depends on the number of systems involved, the available APIs, the complexity of the data and the business rules that need to be handled.
A straightforward integration between two well-documented platforms may take a few weeks, while projects involving multiple systems, legacy software or complex synchronisation can take considerably longer.
After reviewing the requirements, we provide a clear scope and estimated timeline.Third-party APIs can change, so integrations need to be built with those changes in mind.
Where platforms provide versioned APIs and documentation, we follow their supported integration methods and can plan updates when new versions are introduced. For custom or less predictable systems, monitoring and error handling can help identify unexpected changes before they cause wider problems.It can be, particularly where your team repeatedly transfers large amounts of data between systems.
The value depends on the volume and complexity of the work being automated, as well as the cost of maintaining the integration. We can assess the existing process and help determine whether automation is likely to provide a worthwhile return.
