Integration
API development and integration so your systems share data reliably
When systems do not talk to each other, people end up copying data between them. We build APIs for your own applications and connect them to the third-party services you use, with error handling and logging so integrations stay dependable.
Who this is for
- Businesses using several tools that hold overlapping data
- Software teams that need a well-designed API for apps or partners
- Companies integrating payments, shipping, SMS or accounting services
- Organisations with fragile integrations that fail without warning
Problems it can solve
- Staff copy data between systems by hand
- Integrations break silently and errors go unnoticed
- Partners or mobile apps need secure access to your data
- An old integration depends on files emailed or uploaded manually
What is included
What our API Development and Integration service can include
Every project is scoped to your needs. These are the areas we typically cover; we agree the exact list with you before work starts.
API design
Clear endpoints, data formats and versioning for your own platform.
Security
Authentication, authorisation and rate limits to control who can access what.
Third-party integrations
Connections to services such as payment gateways, couriers, SMS, email, CRM and accounting tools.
Webhooks and events
Real-time updates between systems when something changes.
Data mapping
Matching fields between systems and handling differences in format.
Error handling and retries
Logging, alerts and retry rules so failures are visible and recoverable.
Documentation
API documentation that developers inside and outside your company can follow.
Process
How API Development and Integration projects run
A practical sequence with review points, so you see progress and can change direction early.
Map the data
Which systems hold which data, and where it needs to flow.
Design
API contracts or integration flows, including error cases.
Build
Development with automated tests against sandbox environments.
Verify
End-to-end testing with real scenarios and monitoring setup.
Document and support
Documentation, handover and ongoing monitoring.
Order-to-invoice integration
When an order is placed online, an integration could create the invoice in the accounting system, book a courier pickup, and send the tracking number back to the customer, logging each step so failures can be retried.
This is a hypothetical example to explain the service, not a description of a client project.
FAQ
Questions about API Development and Integration
Can you integrate with any software?
We can integrate with software that offers an API, webhooks or a supported import and export method. We check this early.
What happens when an integration fails?
We build logging and alerts so failures are visible, and retries where it is safe to do so.
Do you write API documentation?
Yes. Documentation is part of every API we build.
Can you fix an integration someone else built?
Yes. We review how it works, find why it fails and recommend repair or replacement.
Need two or more systems to work together?
List the tools involved and what should happen between them. We will assess the options.
