Introduction

RiverZone exposes its data via an Application Programming Interface (API). This document is the official reference for that functionality.

Getting Started

  1. Read the documentation (please :)

  2. Contact us at api@riverzone.eu to get an API key.

  3. To start experimenting with a few examples we recommend a REST client called Postman. Simply tap the button below to import a pre-made collection of examples and the associated environment variables.

Run in Postman

See the chapter about Postman on how to install and setup the collection.

Basic concepts

Assumptions

The API is entirely HTTP-based

Methods to retrieve data from the API require a GET request. Methods that submit or change data require a POST. Methods that destroy data require a DELETE. API Methods that require a particular HTTP method will return an error if you do not make your request with the correct one. HTTP Response Codes are meaningful.

The API is a RESTful resource

The API attempts to conform to the design principles of Representational State Transfer (REST). More details on REST can be found here. Libraries to build REST-compatible API clients are readily available for several programming languages. A list of REST frameworks is available at the bottom of the above mentioned page.

The format used for structured data exchange is JSON

The API supports the JSON (JavaScript Object Notation) format. Details on how JSON works can be found here and here. Libraries that convert to and from the JSON format are readily available for popular and less popular programming languages. A full index, sorted by language, can be found at the bottom of this page

SSL/TLS is supported and enforced

The API only works with HTTP-within-SSL/TLS (HTTPS). HTTP requests will be accepted but redirected to the HTTPS endpoint. Issuing HTTPS request from the start is highly recommended to avoid passing both the authentication KEY and potentially confidential data in clear text over the web.

Parameters have certain expectations

Some API methods take optional or requisite parameters. Please keep in mind that all query-string parameter values should be converted to UTF-8 and URL encoded.

Authentication

Authentication is performed using an API key provided by RiverZone. The API key must be included in the HTTPS request using one of the following two methods:

Where both are provided the query-string parameter takes precedence.

The API key is a string, more specifically it is a UUID in its canonical form (e.g.: “123e4567-e89b-12d3-a456-426655440000”).

Throttling

Throttling and rate-limiting schemes are applied on a per-key and per-request-type basis to all requests to prevent overloading the system with too many / too fast requests.

HTTP Response Codes and Errors

HTTP Status Codes

The RiverZone API attempts to return appropriate HTTP status codes for every request.

Error Messages

{
  "errorCode": 3000,
  "errorMessage": "Too many requests in a short amount of time. Slow down"
}

When the RiverZone API returns error messages, it does so in JSON format. See example in the right panel (or above if you’re reading this on a small screen).

Error Codes

Error codes, as found in the body of returned error messages, further define the scope of an error. The following error codes may be returned:

Versioning and evolution

RiverZone API is constantly evolving. Existing methods are being improved and extended and new functionalities are being added.

Backward-compatible changes are implemented as extensions to existing versions, while backward-incompatible changes are implemented by introducing entirely new versions.

While we are strongly committed to never introduce breaking changes to existing versions, integration code must be flexible enough to handle backward-compatible updates gracefully.

Here is a list of backward-compatible changes together with how integration code is supposed to deal with them.

Introducing a new REST resource

This is never a problem as existing integration code, not knowing about new endpoints, will not use them.

Adding properties to existing response objects

Existing integration code should ignore unmapped fields.

Note: Some JSON libraries, most notably Jackson, by default will throw an error in case an unmapped field is encountered during parsing. It is important that such libraries are configured to ignore (and possibly report) unmapped fields rather than fail.

Adding optional properties to existing request objects

This is never a problem as existing integration code, not knowing about the new fields, will not populate them.

Adding new values to existing enums in request objects

This is never a problem as existing integration code, not knowing about the new values, will not use them.

Adding new values to existing enums in response objects

This is trickier and we try to limit it only to cases where the change can be handled in a backward-compatible way.

An example would be adding a new value to Poi‘s type property. Existing integration code should ignore POIs with an unknown type (it is still recommended to log these events to keep track of them).

Test with Postman

Postman is a handy API client that facilitates testing and experimenting with RESTful endpoints.

Installing Postman

Before you can use the RiverZone API Postman Collection, you must either download the Postman App for Windows, OS X, or Linux or you can use Postman online:

Install the API Collection

We’ve created a Postman Collection that contains the main RiverZone API RESTful endpoints, including some examples. Click the Run in Postman button below to get started.

Run in Postman

Environment Variables

In order to use the above collection you will need to set some environment variables in Postman. After importing it, select RiverZone API Environment from the list of environments and populate the following:

This object models 3 types of stations/gauges:

Other visual references (rocks, banks, etc) are modeled as POIs with type=altGauge

Property Type Description
id UUID Globally unique Gauging Station id
type enum One of:
  • online: readings are provided by the water authority owning the gauge
  • manual: readings are provided by users based on direct observation of a physical measuring stick
  • synthetic: readings are computed from readings from other gauges via a formula (e.g.: sum of the flows from 2 tributaries)
revision int Incremented every time details for this station are edited/updated
revisionTs int Updated every time revision is incremented. Unix epoch. Seconds since Jan 01 1970 (UTC)
isActive boolean true if RiverZone is collecting readings from this station, false otherwise (station is “dormant”)
sensors list of enum List of sensors supported by the station. Supported enum values are level and flow
name String Gauging station name (as named by the owning source/authority)
riverId UUID NOT YET SUPPORTED
Id if the River monitored by this station
river map[LanguageCode]String River being monitored by this station
countryCode String ISO 3166-1 alpha-2 Country Code
state String State, region or administrative area, where applicable (depends on country)
latlng LatLng Gauging station location. Null if location is unknown
dataSourceId UUID Id of the entity/authority publishing station data
sourceLinks map[LanguageCode]SourceLink Direct links to the station as published online by the owning authority, where available, or a generic link to the water authority’s page if direct per-station links are not available, or empty if nothing at all is available (e.g.: manual/crowdsourced and synthetic stations)
Links to pages with graphs are preferred over pages with tables or with just the current value.
parserConfigs String A comma-delimited list of settings used by the parser to extract readings for this station.
WARNING: The format and the nature of data contained in this field is different for each source, may be subject to change without notice and is reported here for completeness’ sake only (and because it might help in crafting sourceLink variants)
observationFreqMins int How often the station acquires new samples. Set to -1 if there is no fixed observation frequency because:
- this station is listed-but-not-active (samples are not being actively read and stored)
- this is a manual/crowdsourced gauge
- the samples are acquired erratically
publishingFreqMins int How often new samples are (usually) published by this station, -1 if there is no fixed publication frequency.
Usually the same as observationFreqMins but not necessarily (e.g.: some stations acquire samples every 15 mins but only publish them in bulk every X hours)
note map[LanguageCode]String Notes about this gauging station, curated by experts/editors. Examples:
- influenced by erratic dam release, can be unreliable
- often gets stuck in winter in freezing conditions
synthetic SyntheticGauge Only populated for synthetic-type stations, null otherwise
