API and Interface Development

The Bridge Between Systems
API and Interface Development

What are APIs and Interfaces?

Connecting Systems
An API, also known as a programming interface, allows programmatic access to systems and data. It enables various applications to communicate with each other. This allows existing systems to be extended, processes to be automated, or data sets to be synchronized.

Outgoing and Incoming APIs

Incoming APIs
Incoming APIs are interfaces provided by a system to receive data from other systems. They allow data and functions to be made available to third parties.
Incoming APIs
Outgoing APIs
Outgoing APIs are interfaces used by a system to transmit data to other systems.
Outgoing APIs
Synchronization
With the help of incoming and outgoing APIs, a lossless data flow between systems can be enabled – systems can send and receive data from each other.

Our API Offer

Professional API design is the key to successful applications. We help design a robust, scalable, and user-friendly API that meets specific requirements and enables smooth data flow.
Integrating APIs can be a challenge. We offer tailor-made solutions to ensure seamless data flow between different systems. No matter the system, no matter the scope.
Security is an essential aspect in creating and using APIs. Our team develops secure interfaces with elements such as authentication via Oauth2.0, authorization, encryption, and data validation. We ensure that the API is compatible with the latest security protocols and standards and offer regular reviews and security audits.
Best practices in creating and using APIs include standardized interfaces, taking into account user experience, scalability, flexibility, maintainability, and compliance with industry-standard security standards. We support in choosing the right technologies and architectures for the API and implement them according to best practices. We ensure optimal performance, high user satisfaction, and effective integration into your business processes.
Restful
Restful is the design standard of the hour and allows for efficient and secure data transmission without developers having to delve into a complicated architecture.
Secure
Well-built APIs are secure and only allow the desired user group access to selected data.
User-friendly
Using design standards, APIs and wrappers can be designed that are easy to use and develop further.
Performant
In the age of IoT, latencies are a critical success factor in the establishment or use of APIs.

API Design for Every Use Case

Depending on the initial conditions, different API technologies may be required.
REST
Universal API architecture style for various scenarios
SOAP
XML-based protocol, which is widely used in legacy applications
GraphQL
Flexible data queries via a single endpoint
RPC
Direct procedure calls over networks

Our API Development Process

Step 1: Preparation

Define Requirements
Define Requirements
The requirements for the API are defined. We clarify which data and functions it should provide and who the target audience of the API will be.

Step 2: Implementation

Testing and Documentation
Technical Development
The structure of the API is designed. Aspects such as data format, transmission protocols, and security features are also defined.
Testing and Documentation
Testing and Documentation
At the end of development, we subject every development area to comprehensive automated and manual development tests and security checks. Additionally, upon request, our internal editorial team creates an operations manual, installation instructions, and API documentation.
Acceptance
Acceptance
Upon acceptance, the API is published and accessible to the target audience.

Step 3: Support

Acceptance
Maintenance and Support
If desired, the interface or API will be continuously monitored by us after the development has been completed so that we can respond as quickly as possible in the event of disruptions. In consultation, we keep the entire tech stack up-to-date and further develop the range of functions.
All contact requests are free of charge and non-binding, by phone, e-mail and in person. We are happy about every project and will get back to you as soon as possible.
