API Development & Integrations
We connect your systems through clean APIs, so data flows automatically instead of being copied across by hand.
The problem
Your CRM, store, accounting and website run side by side instead of together. Data is maintained twice, transfer errors pile up and every new tool is a pain to plug in.
What is included
- Analysing your systems and data flows
- Connecting external APIs such as CRM, payment providers, accounting or marketing tools
- Building your own REST APIs and webhooks
- Middleware for syncing, transforming and error handling
- Authentication, rate limits and logging
- Monitoring and error alerts
What you get
- A working integration between your systems
- API documentation
- Data flow diagram
- Error logging and alerting

FAQ
Questions about this service
When is Make.com or n8n enough, and when do I need custom code?
Automation platforms are faster and cheaper for many standard cases. For high volumes, complex logic or missing connectors, we build custom.
What happens when an external API changes?
We monitor the integration and adapt it under a maintenance agreement before it causes outages.
Can you build an API for our software?
Yes. We develop documented REST APIs and webhooks so partners and customers can connect.
