Introduction

Welcome to the Iteris ClearAg Accounts API. This system allows API integrators to create and utilize users, fields, and growths within the ClearAg family of APIs. In addition, this API offers several services for providing information about fields and growths that, in return, provide even greater accuracy and value for users.

Please note that before users can access the ClearAg Accounts API, an active account and license key is required. These credentials will be provided for each service request. To obtain your API key, contact your Iteris account representative.

API Services

The ClearAg Accounts API allows users to edit, add, and delete information related to user access, field details, and growth specifications. Each of the following endpoints outlines the given action and the information necessary when working in the API. If using the Accounts API in conjunction with the Crop Health API, please refer to the Crop Health API documentation for additional information.

Multiple data center regions are available to meet users’ legal and performance needs. Currently, data centers exist within the United States (ag.us.clearapis.com) and the European Union (ag.eu.clearapis.com). Account and related information such as fields and growths are not shared between these regions. Please contact your account representative for account creation and data segregation information.

Additional API information, such as details on supported unit sets and API behavior, is available in the Supplementary API Information section of the Appendix.

1. Users

A unique user ID must be used when performing any action within the Accounts API. The endpoints documented below provide a means of creating and managing user information.

1.1. Create User - v1.0

After first obtaining an account ID provided by Iteris, the Create User endpoint allows for the creation of a user within an account. Once the user is created, a user ID is provided that will be needed to perform most operations within the system. Note that multiple users may be added using a single account ID.

Crop Description

Corn

Must be an integer between 70 and 130. Lower numerical values represent “early” relative maturity, resulting in plants maturing fast. A higher numerical value represents crops that have a “late” relative maturity, meaning a relatively slow maturity. If no value is provided, the default relative maturity is 100.

Spring Wheat

Valid values include “early,” “medium,” and “late.” Crops that have an “early” relative maturity are expected to mature relatively fast, and crops having a “late” relative maturity are expected to mature relatively slowly.

Winter Wheat

Valid values include “early,” “medium,” and “late.” Crops that have an “early” relative maturity are expected to mature relatively fast, and crops having a “late” relative maturity are expected to mature relatively slowly.

Cotton

Categorized by one of the following statements: “early,” “medium-early,” “medium,” “medium-late,” or “late.” If no value is given, a default relative maturity of “medium” will be used.

Soybean

Classification indicating how early a variety matures. Valid values fall into the following range bins: 000.0 to 000.9, 00.0 to 00.9, and 0.0 to 10.9. Multi-zero range bins indicate the earliest maturities, with values near 10.9 indicating the latest maturities. Default is 3.0. Please note that if neither relative maturity nor maturity group are specified, the default value will be stored as relative maturity; if maturity group is specified, it will be stored as relative maturity.
