App-Entwicklung: App API Development
Your app is only as good as the API powering it. A well-structured API delivers data reliably, scales under load, and can be maintained without every update becoming a risk. We build APIs specifically for the demands of mobile apps: low latency, efficient data formats, stable versioning, and clear documentation – so frontend teams can move fast.
Challenges you'll recognise
- Your app API returns more data than needed, slowing down every request on mobile devices.
- Old app versions break after every backend update – you can no longer deploy changes without losing users.
- Your API code is undocumented and hard to follow – every new integration costs disproportionate time.
REST and GraphQL
For mobile apps, the choice of API paradigm directly affects performance and data consumption. REST APIs are simple and widely understood; GraphQL lets the app request exactly the fields it needs – no over-fetching, no wasted requests. We choose the right paradigm based on your specific requirements.
Versioning
Mobile apps cannot force all users to update immediately. That is why app APIs need a clean versioning strategy that keeps older app versions working while new features are rolled out. We build versioning in from the start rather than bolting it on later.
Performance
Mobile users are impatient and often on slow connections. We optimise APIs deliberately: response caching, pagination, compression, and efficient database queries ensure the app stays responsive even under difficult network conditions.
Documentation
An undocumented API is a maintenance trap. We deliver OpenAPI specs that stay automatically up to date, with clear examples for every endpoint. This speeds up the app team's work and makes external integrations predictable.
Good to know
Mobile-First API Design
APIs for mobile apps must handle poor connections, limited bandwidth, and heterogeneous devices. We design with these constraints from day one rather than considering them as an afterthought.
Versioning from Day 1
Breaking changes in an API mean broken apps for users who have not updated. Consistent versioning gives you the freedom to evolve the backend without breaking older client versions.
OpenAPI Documentation
Auto-generated, always-current API documentation speeds up app development and makes external integrations predictable – without manual documentation overhead.
