For C# we highly recommend to use nswag to generate clients, for other languages you can use e.g. swagger
- Integrate generated library code into your project
This section describes basic API principles:
- By default AI is trained for correctness first. Thus, AI rather returns empty result than a wrong value
- AI understands document and delivers facts what is ON the document, but does not make assumptions e.g. on invoice there is 0% and region outside EU then it does not assume it is VAT exempted; only if explicitly VAT exemption is on doc it will be returned
- Versioning: x.y.z
- x: Groundbreaking architecture/functional change
- y: API breaking change leads to impl. effort on your side
- z: added prediction fields, minor technical, functional changes, bug fixes, maintenance releases
- Backward compatible: New version deliveries are seamless for Cloud customers and by default backward compatible. New major features (change version in y) needs a dev update in case you need this new feature
- Cloud API: Most deployments are without downtime, if service window needed we announce it usually 2 weeks ahead
