Decision models

Decision models are scalable and reusable assets that streamline and centralize complex conditional business logic. They allow teams to improve consistency and reduce maintenance by building logic once and reusing it across multiple recipes and projects.

Each decision model includes the following components:

• An input schema that defines the expected input fields.
• An output schema that defines the values the model returns.
• A decision table that provides a single-page view of the business rules.

Refer to the following sections for more information:

• Decision tables
• Decision Models by Workato connector
• Role-based access control
• Create a decision model
• Edit a decision model

Decision tables

Each row in a decision table defines a set of conditions and an output. When a recipe calls a decision model using the Decision Models by Workato connector, the model evaluates each row in the decision table sequentially, from top to bottom. If the input values meet every condition in the row, the evaluation stops and the model returns that row's Outcome values. You can configure a Default outcome to return for each output field if the input values don't match the conditions in any row.

Limitations

Decision tables have the following limitations:

• Decision tables support a maximum 2,000 rows, 50 input columns, and 50 output columns per table.
• Each decision model supports a maximum of one decision table.

Decision Models by Workato connector

The Decision Models by Workato connector allows you to integrate decision models into your recipes.

How to connect to Decision Models by Workato

No configuration is required to set up this connector.

Make decision action

The Make decision action evaluates inputs using your selected decision model.

Input
