API Development & Integrations

Connect Your Systems. Stop Re-Typing Data.

Custom APIs and integrations that make your software work together — orders, payments, CRM, accounting, and government services — so data flows automatically instead of through copy-paste.

API Development & Integrations illustration

Sound familiar?

Re-keying between systems

Staff manually copy the same data between your website, spreadsheets, and accounting.

Manual exports and imports

Every report means exporting a CSV here and importing it there — slow and error-prone.

Tools that won’t talk

Each system holds part of the picture, and nobody sees the whole thing in one place.

Frequently Asked Questions

What systems can you integrate?

If it has an API, we can connect it — payment gateways, CRMs, accounting software, e-commerce platforms, logistics providers, and marketing tools. We also build the APIs for your own software so others can integrate with you.

Can you connect to software that has no API?

Often yes — through database-level integration, file/SFTP exchange, or controlled automation. We’ll assess the safest, most maintainable option for your specific systems during scoping.

Is it secure?

Yes — authentication, encryption, rate limiting, and audit logging are standard, following OWASP practices and PDPA requirements for any personal data that flows through.

Do you provide documentation?

Always. Every API and integration ships with clear documentation so your team — or any future developer — can work with it confidently.
