APIs that connect everything you run.
Secure, well-documented REST and GraphQL APIs for your apps and devices, plus integrations with the payment, messaging and business tools you already use.
API Development at picoBytes
Behind every good app is an API that’s fast, secure and predictable. When it’s badly designed, every new feature takes longer and every integration breaks something else.
We design APIs contract-first, document them clearly and test them automatically, so your mobile, web and device teams can build against them with confidence. We also connect your systems to third-party services, from payments to WhatsApp to your ERP.
What we do
REST & GraphQL APIs
Well-structured APIs with versioning, pagination and clear errors.
Authentication
Secure sign-in with JWT and OAuth, API keys and role-based permissions.
Third-party integrations
Payment gateways, SMS, WhatsApp Business, email, CRMs and ERPs.
Webhooks & automation
Event-driven integrations that keep your systems in sync automatically.
Documentation
OpenAPI specs and docs your developers and partners can actually use.
Performance & monitoring
Caching, rate limiting, logging and alerts for production APIs.
From first call to launch
Discover
We map the requirement, constraints and budget, and agree on what “done” looks like.
Prototype
A proof-of-concept board, clickable design or first build that tests the riskiest parts early.
Build
Development in short milestones with regular demos, on real hardware and real screens.
Launch & support
Production handover, store or server deployment, and updates after release.
Common questions
REST or GraphQL?
REST is simple, cache-friendly and works well for most apps and devices. GraphQL helps when many different screens need different slices of data. We’ll suggest the best fit for your clients.
Can you integrate with our existing software?
Usually, yes. If the software has an API, database access or file exports, we can connect it. We check the access options at the start.
How do you keep APIs secure?
Authentication on every endpoint, encrypted connections, input validation, rate limiting and logging, plus regular dependency updates.
Will we get API documentation?
Yes. Every API we build comes with OpenAPI documentation and example requests.
