Mobile app backends
APIs designed for Flutter and other mobile clients, including auth, uploads and notifications.
API development & integration
API development and integrations that connect your systems
We design and build secure REST APIs for mobile apps and partners, and connect your software to the payment, messaging and business tools you already use.
Systems that don't talk to each other cost you every day
When your website, app, accounting software and payment provider don't share data, staff copy information between them by hand, and errors creep in. A well-designed API lets each system exchange data automatically and reliably.
We build APIs with Django REST Framework: versioned endpoints, token or JWT authentication, permission checks on every request, rate limiting where needed and documentation your developers or partners can follow.
What we deliver
API Development & Integration services
Payment gateway integration
Checkout, webhooks, refunds and reconciliation with your payment provider.
Messaging integrations
Email, SMS and WhatsApp/Messenger notifications triggered by business events.
Third-party and partner APIs
Connecting to suppliers, couriers, marketplaces and accounting tools.
Webhooks and automation
Reliable event handling with retries and logging so nothing is silently lost.
API documentation
Clear endpoint documentation and example requests for your team or partners.
Business benefits
What you gain
No more double entryData moves between systems automatically and consistently.
Secure by designAuthentication, permissions and input validation on every endpoint.
Ready for new channelsOne API can serve a mobile app, a web dashboard and partners.
TraceableLogging and idempotent operations make failures visible and safe to retry.
How we work
Our API Development & Integration process
Clear milestones, working demos and written decisions, so you always know what is being built and why.
- Integration mappingWe list the systems involved, the data that must flow and what should happen when something fails.
- API contractEndpoints, payloads and authentication are agreed and documented before coding.
- Build and testEndpoints are built with automated tests, including permission and failure cases.
- Monitor after launchLogging and alerts help catch integration issues before customers notice.

Read the case study →Do you build REST or GraphQL APIs?
We mainly build REST APIs with Django REST Framework because they are simple to secure, cache and document. We can discuss alternatives if your project needs them.
Can you integrate with a payment gateway in Bangladesh?
Yes, provided the gateway offers an API. We handle checkout, webhooks and reconciliation.
How do you secure an API?
Token or JWT authentication, permission checks per endpoint, input validation, HTTPS only, rate limiting on sensitive endpoints, and no secrets in the mobile app.
Will we get documentation?
Yes. Every API we deliver comes with endpoint documentation and example requests.
