REST API
At Seftali Agency, we design secure, well-documented and maintainable REST APIs for businesses in Samsun, and build reliable integrations with third-party systems such as payment, cargo and ERP.
REST API DEVELOPMENT AND INTEGRATION
A REST API lets your website, mobile app and business software share data in a standard way. Product, order, customer and stock information flows in a controlled manner instead of being typed into every system by hand. That is why we do not start by writing code; we start by clarifying which data flows between which systems, and for whom.
Besides designing APIs from scratch, we connect your existing systems with payment providers, cargo companies, and ERP and accounting software. The goal is clear endpoints, consistent error messages and a structure that makes it easy to add new systems later.
WHY IT MATTERS FOR YOUR BUSINESS
A well-designed API and properly built integrations reduce repetitive work, lower errors and let your systems grow together.
WHAT WE OFFER
Our REST API service covers not only writing code but also design, security, documentation and long-term maintainability.
HOW IS THE PROJECT MANAGED?
DISCOVERY AND DATA ANALYSIS
We listen to which systems will share which data, your current software and constraints. Deliverable: Integration map and scope.
API DESIGN
Endpoints, data models, error structure and the authentication method are planned. Deliverable: API draft for approval.
DEVELOPMENT
The approved draft is coded, with security, validation and rate limiting layers added. Deliverable: Working test environment.
INTEGRATION
External services such as payment, cargo and ERP are connected and flows are tried with real data. Deliverable: Connected and tested integrations.
TESTING AND DOCUMENTATION
Error scenarios, load and security are checked and usage documentation is prepared. Deliverable: Test results and API documentation.
LAUNCH AND MONITORING
The API goes live with logging and error monitoring, and a version and maintenance plan is shared. Deliverable: Live API and maintenance plan.
Every stage ends with a deliverable that is submitted for your approval. This way you always know where the project stands, and we move on to the next stage only with your approval.
API AND INTEGRATION FOR BUSINESSES IN SAMSUN
Manufacturers, retailers and service businesses in Samsun often use several programs at once: an online store, accounting software, a cargo panel and a stock system. When these do not talk to each other, the same work is done twice. Businesses searching for a "Samsun software company" or "Samsun API integration" usually want to tidy up exactly this scatter.
We work with businesses in Ilkadim, Canik, Tekkekoy, Bafra and Carsamba, taking into account their local workflows, the software they use and their cargo or payment preferences. Instead of a ready-made template, we build an integration structure that fits your current setup and leaves room to grow.
COMMON API AND INTEGRATION MISTAKES
- Delivering the API without documentation and leaving later developers to guess
- Postponing authentication and authorization and publishing endpoints openly
- Making changes without versioning and breaking existing applications
- Depending directly on external services without planning for errors and timeouts
- Going live with an integration without trying it on real data and edge cases
FREQUENTLY ASKED QUESTIONS
?How does API development and integration start for a business in Samsun?
We begin with a discovery where we clarify which systems will share which data. Then the scope, security approach and timeline are prepared, and development starts with your approval.
?Can you integrate my existing software without replacing it?
In most cases, yes. We examine the API or data transfer method your software offers and build a connection layer in between. If there are limits, we explain the alternatives during discovery.
?How is API security handled?
Token-based authentication, role-based authorization, encrypted connections, request limiting and logging are used together. Which data is opened to whom is planned from the start.
?Can the API be changed after delivery?
Yes. With versioning, new features are added without breaking current users. We can plan support options for maintenance, monitoring and further development that fit your needs.
