The decision object

A decision is the main ressource to interact with.

It contains an outcome, as well as details (scenario, score, rules) that you can use to trigger specific actions in your application.

Attribute	Description
id string	ID of the decision.
app_link url	Link to the app with the detail of the decision, including intermediate values.
created_at timestamp	Time at which the object was created (received by Marble, before executing scenarios). Measured in seconds since the Unix epoch.
trigger_object object(trigger_object)	Trigger object data, for example a full transaction.
trigger_object_type string	Trigger object type, for example `transaction`.
outcome ENUM(string)	`approve`, `decline`, `review`, `block_and_review`,`null` `null` if the scenario could not compute a score.
scenario object(scenario)	Scenario that was executed. See scenario.
rules array[rule]	Array of rules executed in the scenario. See rule.
score int	Score computed by the scenario (sum of all `score_modifier` of rules that evaluated to`true`). Only present if `outcome != null`.
scheduled_scenario_execution_id string	ID of the scheduled scenario execution. Only present if the decision was created by a scheduled scenario execution

The scenario shows details about the scenario executed.

This is mainly useful to display its information in a third-party system, like a case manager.

Attribute	Description
id string	ID of the scenario.
name string	Name of the scenario.
description string	Description of the scenario.
scenario_iteration_id string	Unique identifier of the scenario version use in this decision
version string	Version of the scenario.

The rule provides all the detail of the rules that were computed to produce an outcome.

This is mainly useful to display its information in a third-party system, like a case manager.

Attribute	Description
name string	Name of the rule.
description string	Description of the rule.
score_modifier int	If the rule is true, this is added to the scenario's score.
result bool	Did the rule evaluate to true or false ?
rule_id string	Unique identifier of the rule version used in this decision
error object	Error when executing the rule. See error.

The error provides more context when a scenario was not able to produce an outcome, or a rule was not able to produce a score.

Note that error == null if Marble was able to produce an outcome (ie when decision.outcome != null).

Attribute	Description
code int	Machine-readable error code.
message string	Human-readable error message.

Possible errors on the decision object:

code	message
100	Scenario was not able to compute a score because all rules failed.

Possible errors on the rule object:

code	message
200	A field ({field name}) in rule is empty or missing
