What Is an API?

A service contract that lets applications share data and business functions in a secure, defined and reusable way.

An API defines how web, mobile, SaaS and enterprise systems communicate with each other. It validates requests, checks permissions, runs business rules and delivers results in a standard format, enabling faster development of digital products.

Standard communication

Let applications access data and functions through defined request, response and error contracts.

Controlled access

Protect your services with authentication, authorization, rate limiting and validation rules.

Reusable services

Use the same business functions consistently across web, mobile, partners and internal applications.

Independent scaling

Keep performance steady by scaling heavily used services independently of the rest of the application.

API Types and Capabilities

Build the right service model for every application and integration need.

We design the most suitable API approach for requirements such as real-time processing, flexible data querying, high-volume event streaming or legacy system compatibility.

REST API development

Build clear, scalable services that follow HTTP standards for web, mobile and enterprise applications.

  • Resource-oriented endpoint design
  • JSON requests and responses
  • OpenAPI documentation

GraphQL API

Provide flexible, type-safe data access in which clients select the fields they need in a single request.

  • Schema and type design
  • Query and mutation structure
  • Subscription support

SOAP and enterprise services

Stay compatible with existing enterprise systems that need strong contract, transaction and security standards.

  • WSDL and XML contracts
  • WS-Security compliance
  • Legacy system connections

Webhook and event APIs

Automatically notify relevant systems of orders, payments and status changes with low latency.

  • Event publishing and subscription
  • Signature and source verification
  • Retry and delivery tracking

Third-party API integration

Connect payment, shipping, maps, communication and partner services to your application with secure adapters.

  • External service adapters
  • Data transformation and mapping
  • Error and quota management

API gateway and management

Control service access, traffic, versions and usage metrics in a central management layer.

  • Identity and access policies
  • Rate limiting and quotas
  • Logging and analytics
Ready-Made Connector or Custom API?

The right approach depends on how critical and unique the connection is for your business.

Ready-made connectors can give you a quick start for standard data transfer and common applications. A custom API is more sustainable when you need custom business rules, high traffic, strong security and long-term productization.

STANDARD SOLUTION

Ready-made connector

Suited to teams that want to set up limited, standard data transfer between common applications quickly.

  • Quick startShort setup with ready-made fields and triggers
  • Low upfront effortLittle development and infrastructure needed
  • Common application supportDefined product and service connections
  • Limited control and flexibilityData, rule and quota limits set by the platform
Best suited for Standard flow · Low volume · Quick connection
FLEXIBLE SOLUTION

Custom API development

Built for projects where data and business functions must be delivered in a controlled way according to security, performance and product goals.

  • Custom data and business contractsFull alignment on fields, rules and error behavior
  • Advanced security controlIdentity, scope, quota and audit policies
  • Performance and scale managementArchitecture optimized for transaction volume
  • Controlled lifecycleVersioning, documentation and backward compatibility
Best suited for Custom business rule · High traffic · Productization

Signs that you need a custom API

If several of the following apply to your project, custom API development may be a better fit than a ready-made connector.

  • Data-specific permissions and access rules must be applied.
  • Standard connectors do not meet the required business rules.
  • High request volume and low response time are targeted.
  • Multiple web, mobile or partner applications will use the same service.
  • The API's versioning, SLA and developer experience need to be managed.
  • You want full control over the data and service lifecycle.

API Development Process

A contract-first, testable and observable development model from requirement to live service.

We treat an API project not just as endpoint development but as a product process in which data ownership, security, error behavior, performance and developer experience are designed together.

  1. 01

    Requirement and consumer analysis

    We identify the applications that will use the API, the data to be shared, business functions, traffic expectations and security boundaries.

  2. 02

    Contract and architecture design

    Before development, we design resources, endpoints, data schemas, error codes, versioning and the identity model.

  3. 03

    Service development

    We develop business rules, data access, validations and security controls in line with the agreed contract.

  4. 04

    Automated testing and security

    We verify normal, faulty, unauthorized and heavy-traffic scenarios with automated tests and apply security controls.

  5. 05

    Documentation and sandbox

    So API consumers can get started quickly, we prepare interactive documentation, sample requests, error explanations and a test environment.

  6. 06

    Release and monitoring

    We release the API in a controlled way and continuously monitor usage, errors, latency, capacity and security indicators.

Benefits of Custom API Development

Turn your application capabilities into powerful services that new products and channels can use quickly.

Well-designed APIs reduce dependencies between development teams, standardize integrations and let digital products scale securely.

Faster product development

Speed up web, mobile and partner projects by reusing shared data and business functions.

Lower system dependency

Decouple applications with clear contracts so a change in one system affects others less.

Secure data sharing

Expose data only to permitted users and systems with identity, authorization, quota and validation rules.

Independent scalability

Scale heavily used endpoints and services independently according to traffic needs.

New channels and partners

Create new sales channels and business models by opening existing functions to different clients in a controlled way.

Observable operations

Make service health visible by monitoring request, error, latency, capacity and usage metrics.

API Security and Scalability

A reliable API architecture that protects your services on every request and grows with traffic.

We treat API security not as a layer added afterward but as an end-to-end approach in which identity, authorization, data validation, traffic control and observability are designed together.

Identity and authorization

Verify user, application and service identities and apply scope- and role-based access to every resource. OAuth 2.0 OIDC JWT Scope

Traffic and abuse control

Protect service capacity with quotas and rate limits per client, user or endpoint. Rate limit Quota Throttling

Data and request security

Apply transport encryption, schema validation, sensitive field protection and secure key management. TLS mTLS Validation Secrets

Audit and threat monitoring

Centrally monitor service access, security violations and unusual usage behavior. Audit log WAF SIEM Alert

Send your question
What is API development?

The process of designing, coding, testing and operating API contracts that let applications share data and business functions through secure, standard and reusable services.

Should we use REST, GraphQL or SOAP?

The choice depends on the consumers, data querying needs, real-time behavior, security standards and existing systems. Different service types can also be used together in one project.

How long does an API development project take?

The duration depends on the number of endpoints, business rules, data sources, security, integration and performance scope. After discovery, a phased roadmap is prepared for the priority services.

How is API security ensured?

Authentication with OAuth 2.0, OIDC, JWT or mTLS; role- and scope-based authorization, TLS, request validation, rate limiting, secure key management and audit logs are applied.

Can an API be added to an existing system later?

Yes. By analyzing the existing application's architecture, data model and security boundaries, a suitable service layer, adapter or modernization approach can be developed.

Is API documentation delivered?

Yes. OpenAPI/Swagger documentation covering endpoints, fields, schemas, identity, error codes and examples is provided, along with a developer guide, code samples and a sandbox environment when needed.

How are API performance and capacity tested?

Load, stress and endurance tests are run under expected and peak traffic scenarios. Bottlenecks are resolved by measuring response time, error rate, transaction capacity and resource usage.

Is API support provided after going live?

Depending on the project scope, monitoring, alerting, error analysis, capacity improvement, security updates and new endpoint and version development services can be offered.
