Conventions | OData

Introduction

In this section you can find a description of the available OData V4 conventions and the conventions adopted by CaaS OData endpoint to identify patterns like: Nullability, Empty Value and more.
Those conventions are also reported as "section" inside each API description page

Null and Empty values

In the following table we have listed all "null" and "reset" value for each data type exposed by CaaS OData endpoint.

Null
It is used to represent a non-value that didn't change. When null is passed, OData will not parse the value and not keep it into consideration.
If the value is required passing null will cause a Validation Error.
Reset
It is used to reset a value in the Datastore to null/empty.
Each Data Type accept a specific value to be used which get parsed by OData and translated it "reset the value to its default/null value".
