Validation

All data sent to the API will passed through three layers of validation: schema, logical and data integrity.

Schema Validation

Each data object has a schema file that represents its required shape and some basic validation rules. Data must conform to the schema definition; even if you are using JSON.

The latest schema pack can be downloaded from here.

Logical Validation

Logical validation rules ensure that data is not contradictory to itself; for example an employee leaving date cannot be before their start date. The full list of logical validation rules and their meaning are detailed in the table below.
