Conditions

Every element in the form may have two types of conditionals: required_conditions (to force data entry into the given field) and visible_conditions (to hide/show fields dynamically -- to enable "decision tree"-like functionality).

operator	string	Condition operator (`"equal_to"`, `"not_equal_to"`, `"is_empty"`, `"is_not_empty"`).

Validations

The following properties must be included in order to create/update a form object in our system. Any validation errors will return a 422: Unprocessable Entity and an object with a list of validation errors.

Required Form Properties

Property	Type	Description	Example
name	string	The name you've given this form.	`"Fire Hydrant Inventory"`
elements	array	Custom form elements.	Required element properties vary by field type (see form element properties tables above).

Example validation response if the name is not included:

{
  "form": {
    "errors": {
      "name": ["cannot be blank"]
    }
  }
}

Notes

The entire form object is required when making an update. Omitting existing elements will result in data loss! The typical workflow for updating an existing form is to fetch the form object, modify it, and then submit the PUT request.
