## In short
API development and integration connects software systems so they exchange data automatically. LOLCorp builds secure, documented APIs and integrates third-party platforms, automating workflows and reporting across your tools.

## Why integration work pays for itself
Most businesses run on a patchwork of tools that do not talk to each other, and staff fill the gaps by hand. Third-party API integration connects those tools so an order, a payment or a form submission triggers everything that should follow.

Our API development services cover both consuming other platforms’ APIs and building your own, whether that is an API for a mobile app, a partner integration or a public developer platform. We also build the internal business tools, dashboards and workflow automation that sit on top of the connected data.

## FAQ
### What is API integration?
It is connecting two or more software systems so they can exchange data automatically, for example syncing orders from your shop to your accounting software.

### Can you integrate with our existing software?
Almost always, as long as the system has an API or a data export. We will tell you honestly if it is not feasible.

### How much does an integration cost?
Simple integrations are quick and affordable. Complex ones depend on the systems involved. We quote a fixed price after reviewing the APIs.

### Do you document the APIs you build?
Yes, with clear documentation that your team or partners can use.
