nextbike-api-reverse-engineering

This HTTP-API documentation is what I got from reverse engineering the nextbike app.

There are two different apps:

A web view based app which was discontinued. The interface is still available, though. It's a monolithic javascript web app, performing ajax requests to an API. They use xml format (with .xml endings) for the most requests (although similar functionality is given when changing the suffix to .json)

A native app, which replaces the 1. app since version 4.x (probably).

Base URL and Versioning

All the API versions listed here seem to deliver the same functionality (unconfirmed).

Base URL: https://api.nextbike.net/
- api/ used as standard here
- api/v1.1/
- api2/
Webview URL: https://webview.nextbike.net/

Obtaing API key

It seems as they use hardcoded API keys in their new, (probably) native app. In the old webview based app, the endpoint https://webview.nextbike.net/getAPIKey.json returns a key that is always the same. Maybe they change it when bumping versions in the app or regularly in the webview endpoint.

You can either get the the api key via the endpoint or use the hardcoded one.
