Your application can do much more than echo data from our APIs. These tutorials should help explain the background behind our APIs as well as the agronomic science they open up. The more context you understand, the better your app can be.

Intro to Restful APIs

aWhere’s API platform is built as REST-based web services. Any application or programming language that connects to and interact with the wider Internet can easily integrate our data. There are four essential parts to implementing RESTful APIs using HTTP—URIs, verbs, headers and status codes, and payloads.

Growing Degree Days (GDD)

In agronomy the standard metric for heat measurement is the growing degree-day, or GDD (it’s also called a growing degree unit, GDU, but GDD is the more common term). While many other factors influence plant development, the GDD is a simple starting point that is used by most farmers for tracking their crop growth.

Potential Evapotranspiration (PET)

Evapotranspiration is a metric that gauges how quickly water leaves the earth, either through evaporation or through a plant’s use of water (some of which is ultimately lost as water vapor). Water that leaves the earth needs to be replenished, either by rain or by irrigation, in order for plants to have sufficient supply to grow. Potential Evapotranspiration (PET) is the calculation, based on weather, of how much water is likely to evapotranspirate over a certain amount of time.
