Introduction

Welcome to the Iteris ClearAg Accounts API. This system allows users to create and utilize a tightly integrated interface of ClearAg APIs featuring several field/growth-specific capabilities, including growth models, irrigation, nutrient, and harvest drydown services.

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 is used to create, add, modify, and delete individual users and the field(s) associated with each user. This is the primary mechanism that enables ClearAg’s field and crop-specific agronomic API services to track and record the state of the crop and benefit from user input and feedback. Having a field ID created by the Accounts API is the first step in using many of the Crop Health API endpoints, including the growth, nutrient, and drydown models, as well as custom soil modeling and irrigation recommendation services.

Note that while at least one user ID must be established in order to create and manage one or more fields, it is not necessary from a technical perspective to create individual accounts for each end user of an application that uses the ClearAg APIs, nor is it necessary that user accounts include any kind of personally identifiable information (PII). It is the responsibility of the authorized API user to implement the use of the Accounts API in such a manner that complies with any applicable PII laws or regulations to which their business is subject.

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. Additionally, the ClearAg Customer Success Team can provide best practice recommendations on integrating the Account API for your particular use case.

Please note that API responses are currently only provided in English.

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.
